European Aviation Safety Agency
Notice of Proposed Amendment 2018-04
Helicopter emergency medical services performance
and public interest sites
RMT.0325 & RMT.0326 (OPS.057(a) & OPS.057(b))
EXECUTIVE SUMMARY
The objective of this Notice of Proposed Amendment (NPA) is to contribute to the achievement of the overall objectives
of the EASA system, which are defined in Article 2 of Regulation (EC) No 216/2008 (the Basic Regulation).
This NPA, therefore, proposes to:
— foster efficient and proportional rules, more precisely regarding:
HEMS requirements for high altitudes;
a new HEMS concept to cover mountain operations and rescue operations (other than search and rescue
(SAR) operations);
— maintain a high aviation safety level by reviewing the requirements related to flights to/from public interest sites
(PISs) located in congested areas; and
— maintain a high aviation safety level by reviewing the requirements related to HEMS flights by day or night,
regarding equipment, training, minima, and operating/hospital site illumination.
The proposed draft amendments are expected to increase safety, improve harmonisation and ensure alignment with
ICAO while keeping the economic impact for HEMS operators to a minimum.

1. About this NPA
1. About this NPA
1.1. How this NPA was developed
The European Aviation Safety Agency (EASA) developed this NPA in line with the Basic Regulation and
the Rulemaking Procedure1. This rulemaking activity is included in the EASA 5-year Rulemaking
Programme2 under rulemaking task RMT.0325 & RMT.0326 (OPS.057(a) and OPS.057(b)). The text of
this NPA has been developed by EASA based on the input of the RMT.0325/0326 Rulemaking Group
(RMG), on the comments received following the publication of the subsequent HEMS concept paper,
and on a focused consultation. It is hereby submitted to all interested parties3 for consultation.
1.2. How to comment on this NPA
Please submit your comments using the automated Comment-Response Tool (CRT) available at
https://hub.easa.europa.eu/crt/4.
Please submit your responses to the questions asked in the impact assessment part of this NPA by
responding to the related EU Survey ‘RIA questions for RMT.0325’, which is available at:
https://ec.europa.eu/eusurvey/runner/RMT0325_questions_for_NPA
The deadline for submission of comments is 18 September 2018.
1.3. The next steps
Following the closing of the public commenting period, EASA will review all comments.
The outcome of the NPA public consultation will be reflected in a comment-response document (CRD).
Based on the comments received, EASA will develop an opinion containing the proposed amendments
to Regulation (EU) No 965/2012 and will publish the CRD concurrently with the opinion.
The opinion will be submitted to the European Commission, which will use it as a technical basis in
order to prepare an EU regulation.
Following the adoption of the regulation, EASA will issue a decision containing the related acceptable
means of compliance (AMC)/guidance material (GM).

EASA is bound to follow a structured rulemaking process as required by Article 52(1) of Regulation (EC) No 216/2008. Such a
process has been adopted by the EASA Management Board (MB) and is referred to as the ‘Rulemaking Procedure’.
See MB Decision No 18-2015 of 15 December 2015 replacing Decision 01/2012 concerning the procedure to be applied by EASA for
the issuing of opinions, certification specifications and guidance material (http://www.easa.europa.eu/the-agency/management-

2. In summary — why and what
2. In summary — why and what
2.1. Why we need to change the rules — issue/rationale
Amendments to the Air OPS Regulation are needed to properly address the issues regarding HEMS
operations stemming from stakeholder feedback, non-transposition of JAA material, and non-
implementation of or deviation from the rules, including:
— helicopter performance, in particular performance in high mountains;
— public interest site (PIS) provisions;
— the safety level of helicopter emergency medical service (HEMS) flights, especially at night;
— the delegation of line maintenance tasks to the HEMS technical crew member.
Exemptions5 in accordance with Article 14 ‘Flexibility provisions’ of the Basic Regulation relevant to
the scope of this RMT:
The UK CAA issued Safety Directive (SD) No SD-14/003, introducing additional requirements to increase
the safety of HEMS flights at night, as an immediate reaction to a safety problem in accordance with
Article 14.1 of the Basic Regulation, has been reviewed.
Alternative means of compliance (AltMoCs) relevant to the scope of this RMT:
The Finnish AltMoC regarding the safety of single-pilot HEMS flights has been reviewed.
Three AltMoCs regarding the use of the cargo sling for mountain HEMS operations have been
reviewed.
ICAO and third-country references relevant to the scope of this RMT:
The 2014 FAA amendment to FAR.135 regarding air ambulance operations has been reviewed,
although no alignment was specifically sought.
Operations to and from PISs
Under JAR-OPS 3 of the JAA, it was established that many Member States (MSs) had encountered
problems with fully applying the performance rules where helicopters were operated to some sites in
the public interest and in particular for HEMS and air ambulance operations to some hospitals in
congested hostile areas. Although MSs accepted that progress should be made towards operations
where risks associated with a critical engine failure were eliminated, or limited by the exposure time
5
Exemptions that have an impact on the development of this RMT’s content and that refer to:
— Article 14.1: Measures taken as an immediate reaction to a safety problem;
— Article 14.4: Exemptions from substantive requirements laid down in the Basic Regulation and its implementing rules in the
event of unforeseen urgent operational circumstances or operational needs of a limited duration;
— Article 14.6: Derogation from the rule(s) implementing the Basic Regulation where an equivalent level of protection to that
attained by the application of the said rules can be achieved by other means;
— Article 22.2(b): Individual flight time specification schemes deviating from the applicable certification specifications which
ensure compliance with the essential requirements and, as appropriate, the related implementing rules.

2. In summary — why and what
concept6, a number of landing sites still exist that do not (or never can) allow operations to
performance class (PC) 1 or 2 requirements as they should.
These sites are generally found in a congested hostile environment:
(1) in the grounds of hospitals; or
(2) on hospital buildings.
The problem of hospital sites is mainly historical and, whilst MSs could insist that such sites are not
used — or only used at such a low weight that critical engine failure performance is assured – it would
seriously curtail a number of existing operations.
Even though the rules for the use of such sites in hospital grounds for HEMS operations attract
alleviation, it is only partial and will still impact upon present operations.
Due to the fact that such operations are performed in the public interest, it was felt at the time the
rules were drafted that the relevant authority should be able to exercise its discretion so as to allow
continued use of such sites provided that it is satisfied that an acceptable level of safety performance
can be maintained — notwithstanding that the site does not allow operations to PC1 or PC2 standards.
However, it is in the interest of continuing improvements in safety that the alleviation of such
operations be constrained to existing sites, and for a limited time period.
The aim was to use the PIS provision only for hospital sites that could not be modified and could not be
made compatible with the helicopter performance requirements. This should have restricted their use
to a limited number of historical sites.
A hospital landing site is a take-off and landing site where the site dimensions and obstacle
environment are known in advance. It is similar to an aerodrome in that respect. The differences
between a hospital landing site and an aerodrome or heliport are that the features, dimensions,
obstacle control and aeronautical information services (AIS) are not under the control of the helicopter
operator, are not within the remit of EASA and, in some cases, are not under the control of the
national aviation authority (NAA) either.
PISs are an operational solution to a wider problem. This operational solution has safety implications.
The reduction in the safety level from normal CAT requirements is considered and accepted by MSs as
long as there is a public interest to keep conducting essential helicopter operations to a particular
hospital site.
New hospital landing sites should be designed with due regard to the helicopter performance
requirements. This aim has not been achieved by the current set of rules: the operating rules should
ensure that, in the long term, PC1 will be achievable at all or most of the hospital landing sites. The
current rules do not achieve this goal and should therefore be amended.
Mountain operations and other than search and rescue (SAR) operations
Regarding mountain operations, the current HEMS rules are not suited to mountain operations above
10 000-ft density altitude, but serve their purpose for low-altitude operations. One of the aims of this
NPA is to ensure that HEMS rules are adapted to any kind of terrain, therefore negating the need for a
separate definition of mountain operations. Currently, MSs are conducting mountain HEMS operations
6
‘Exposure time’ means the actual period during which the performance of the helicopter with the critical engine inoperative in still
air does not guarantee a safe forced landing or the safe continuation of the flight.

2. In summary — why and what
in different ways. Some are conducting them according to national rules, because they consider
mountain HEMS operations as state or similar services falling outside the scope of the Basic Regulation.
Other MSs are conducting them according to CAT and HEMS rules, and use a number of AltMoCs and
multiple flexibility provisions to adapt the rules to mountainous environments.
Regarding other than SAR operations, where a person is endangered by the environment and, as far as
can be assessed at the moment of initiating the rescue operation, not by a medical condition, are
currently not covered by the HEMS rules. It should be noted that SAR operations are clearly not within
the remit of EASA as they fall outside the scope of the Basic Regulation. ICAO defines SAR operations as
follows:
— search: an operation, normally coordinated by a rescue coordination centre or rescue sub-
centre, using available personnel and facilities to locate persons in distress.
— rescue: an operation to retrieve persons in distress, provide for their initial medical or other
needs and deliver them to a place of safety.
It is an institutional service coordinated by rescue centres, mainly for the purpose of providing
assistance to aircraft.
Some MSs apply national rules for other than SAR operations because they consider other than SAR
operations to be state or similar services. Other MSs do not have national rules for other than SAR
operations or include mountain HEMS and other than SAR operations in HEMS operations: in order to
ensure the same level of assistance to people living in a town or to people undertaking activities or
living in mountainous areas, some MSs do not distinguish between HEMS and other than SAR
operations. Those MSs have a single HEMS concept of operations.
The resulting situation is the lack of a level playing field across European mountains, the duplication of
effort in the design of flexibility provisions and development of national rules, and the lack of exchange
of best practices.
The aim of this NPA is to enable MSs to include other than SAR operations into the HEMS concept of
operations. In order to do this, special techniques and equipment that are needed for these operations
(rescue hoist, hook, hovering disembark and embark) need to be introduced in the CAT HEMS
regulatory framework.
Other than mountain HEMS operations
HEMS operations involve higher levels of risk than pure CAT operations, since HEMS operations may
have a direct impact on the patient’s health or even their survival. Some MSs have argued that current
rules do not make that industry sector safe enough. The available accident data supports the idea that
HEMS operations at night or in marginal weather conditions can be improved.

2. In summary — why and what
Safety risk assessment
A data analysis of the 26 major HEMS accidents that took place in Europe during the period 2005–2014
has been used. The conclusions were the following:
Accidents/major incidents % of % of fatalities and serious Related issue
occurrences injuries
Loss of visual reference 17 % 46 % Mountain and other than
mountain operations
Collision with obstacles during final 21 % 14 % Mountain and other than
approach or hover at the operating mountain operations
site
Power-plant-related issues 8% 16 % Public interest sites and mountain
operations
Other system failures 12 % 0% Not applicable
Other crew-related issues 23 % 20 % Mountain and other than
mountain operations
Other issues 19 % 4% Not applicable
The data available allows to identify the main risk factors in HEMS operations. However, the figures are
too small to identify which options are best suited to prevent the recurrence of accidents. Moreover,
the data set relates to the JAA times, and it was not feasible to identify which parts of the JAA material
were effectively transposed into national rules when the various accidents took place (in the 2003–
2014 period and in different MSs). For this reason, the analysis has to rely on expert judgement,
including the analysis of the safety impacts of the options further in the text.
2.2. What we want to achieve — objectives
The overall objectives of the EASA system are defined in Article 2 of the Basic Regulation. This proposal
will contribute to the achievement of the overall objectives by addressing the issues outlined in
Chapter 3. The specific objectives of this proposal are to:
— foster efficient and proportional rule, more precisely regarding:
HEMS requirements for high altitudes;
a new HEMS concept to cover mountain operations and rescue operations (other than
SAR operations);
— maintain a high aviation safety level by reviewing the provisions related to flights to/from PISs
located in congested areas; and
— maintain a high aviation safety level by reviewing the requirements related to HEMS flights by
day or night, regarding equipment, training, minima, and operating/hospital site illumination.
2.3. How we want to achieve it — overview of the proposals
2.3.1. Public interest sites (PISs)
The term ‘public interest site’ (PIS) covers two different derogations from the helicopter performance
requirements: the derogation in Article 6.6 of the Cover Regulation, and the derogation in
point CAT.POL.H.225. Article 6.6 was introduced as a temporary, transitional arrangement to

European Aviation Safety Agency NPA 2018-04
2. In summary — why and what
accommodate differing actions by some MSs. The aim of the current proposal is to merge the two
differing schemes of Article 6.6 and point CAT.POL.H.225 into a single one. The following principles
have been established in order to merge the two schemes:
The merged PIS derogation should be defined in point CAT.POL.H.225, and the provisions in Article 6
should no longer be needed.
Sites that were legitimately granted PIS derogations under Article 6.6 should remain eligible to PIS
derogations under new point CAT.POL.H.225.
Such sites belong to two categories:
— hospital landing sites that are eligible to the current CAT.POL.H.225 derogations (i.e. those sites
that had been in use before 1.7.2002);
— hospital landing sites that have been operated for the first time between 1.7.2002 and
28.10.2014, and would have been eligible to the current CAT.POL.H.225 derogation, if they had
been operated before 1.7.2002. The provisions of Article 6.6 are applicable only to existing sites.
The Air OPS Regulation, which introduced Article 6.6, was published on 25.10.2012 and has been
in force since 28.10.2014.
Any new hospital landing site that had not been in use before 28.10.2014 is expected to be designed
with due considerations to the Air OPS helicopter performance rules. New hospital landing sites are
not eligible to any derogation.
It appeared that Article 6.6 has not only been used for the continuation of use of existing sites, but also
to bring new hospital landing sites into existence after 28.10.2014 and then to approve these ‘newly
existing sites’ as PISs. This situation is assumed to have happened only in a couple of MSs.
Such practice should not be possible and should be discontinued. Moreover, it should be made clear
that new hospital landing sites that came into existence after 28.10.2014 are not eligible to a PIS
derogation.
Article 6.6 should remain applicable until 31.7.2022 in case such hospital sites had been approved as
PISs, and a disruption to the health services was unacceptable, and a transition period of up to 5 years
was needed to render such sites compatible with the needs of the operators and the helicopter
performance requirements applicable to them.
It is also reinforced that there will be no approvals of new PISs.
— If a hospital landing site is currently compatible with the helicopter performance requirements,
the obstacle environment should be controlled in such a way that helicopter performance
requirements are complied with, otherwise the helicopter operations should be discontinued.
— It is also expected that, if the current fleet of HEMS and air ambulance helicopters is capable of
operating in compliance with the helicopter performance requirements and without a PIS
exemption, the operators will not change their fleets in such a way that safety would be
decreased over congested hostile areas. The increased risk to third parties should not be
accepted.
The worsening of the obstacle environment at existing PISs should also be avoided.
— NAAs usually have no competency on building restrictions or the growth of trees outside
aerodromes, where not covered by safeguarding arrangements.

2. In summary — why and what
— However, NAAs should monitor the obstacle environment at PISs through review of the
operator’s approvals. The current guidance material already foresees a national directory of PISs,
where site dimensions and obstacle environment at PISs should be recorded.
— NAAs should be capable of monitoring any changes in the obstacle environment at a PIS by
checking the amendments to the operator’s operations manual and ensuring that operators
amend their operations manuals as part of the oversight cycle. In order to mandate this, the NPA
proposes to introduce an additional requirement for operators to ensure that PIS data in the
operations manuals remains valid and that any change to this data is notified to the competent
authority and the authority of the state of the PIS. This proposal does not preclude NAAs from
developing their own obstacle-monitoring activities at hospital sites and heliports.
— If the obstacle environment has permanently changed in such a way that exposure time has
significantly increased in certain wind conditions, NAAs should reassess and, if necessary, revoke
the PIS approval for this site. In order to achieve this, the NPA proposes to introduce a new
requirement in Part-ARO, and proposes to move the guidance on national directories of PISs to
AMC.
Date on which approved PIS was established Maximum duration
of the PIS approval
Before 28.10.2014 Unlimited duration, provided
there is no permanent worsening
of the obstacle environment.
After 28.10.2014 PIS approval to expire by
31.7.2022 together with
Article 6.6 provisions
Helicopter hospital landing sites are typically not EASA-certified aerodromes. The following are outside
the remit of the operational rules and outside the scope of the Basic Regulation:
— any aerodrome regulation regarding the obstacle environment at PISs;
— any aeronautical information service (AIS) requirements, such as obstacle charts at PISs;
— any rules regarding the confidentiality of obstacle data that has been collected by individual
operators.
The NPA proposes that the obstacle monitoring activities performed by the NAA should be required
only for the purpose of granting, maintaining and revoking PIS approvals. The proposal does not
prevent NAAs from using the directory of PISs for other purposes (such as AIS), subject to national
regulations or requirements.
It would be desirable for operators to reduce the burden associated with the evaluation of PC1
capability at every hospital site, and the burden associated with obtaining PIS approvals for each
individual site. This would be especially useful when an operator is urgently requested to fly outside its
usual territory. The following was considered:
The determination of the PC1 capability remains an operator task because it is type-specific and may
depend on parameters such as cabin configuration and fuel load.

2. In summary — why and what
It is good practice for hospitals and/or MSs to chart the obstacle environment in the vicinity of hospital
landing sites. It does help the operator to identify in advance at which sites it can operate in PC1 and at
which other sites it can only operate with a prior PIS approval. However, this good practice should not
be mandated through operational rules.
In those MSs where such practice is not in place, it is for the operators to pre-survey the obstacle
environment at hospital sites in advance, define whether or not PC1 can be complied with, seek PIS
approvals as needed and define site-specific contingency procedures. Operators have to coordinate
with the medical needs of their clients, in order to know in advance to which hospital sites they may be
requested to fly.
Since a number of hospital sites may remain PISs in the foreseeable future, it was considered
important to keep minimum performance margins when operating to these sites. The required
performance level of 8 % climb gradient in the first segment reflects ICAO Annex 14 Volume II in ‘Table
4-3 ‘Dimensions and slopes of obstacle limitations surfaces’ for PC2 and establishes a means of
mitigating performance issues. This requirement is retained because it defines a proportionate mass
penalty at PISs, thereby applying an additional performance margin to such operations.
The NPA proposes to amend the following in accordance with these principles:
— Article 6,
— point ARO.OPS.220,
— point CAT.POL.H.225, and
— create new AMC3 ARO.OPS.220.
2.3.2. Mountain operations and other than SAR rescue operations
2.3.2.1 Applicable regulations
The aim of the current proposal is to adapt the existing HEMS rules to mountain operations and to
other than SAR rescue operations. The intent is also for the MSs that wish to do so, to be able to adopt
European rules without introducing national variations.
MSs that want to keep mountain HEMS and other than SAR rescue operations under national rules
should also be able to use the Air OPS Regulation as a reference for the drafting of their rules.
Two kinds of operations have been identified as other than SAR operations, and are not currently
included in the definition of HEMS:
— Operations where a person is at an imminent or anticipated future health risk from the
environment and needs to be rescued or provided with supplies;
— Operations where persons (other than medical professionals), animals, or equipment (other than
medical equipment) need to be transported to and/or from a HEMS operating site. The supply of
avalanche rescue operations is a typical example of such operations.
Not only the nature of the flights performed as other than SAR rescue operations, but also the risks
involved in such operations were assessed to be equivalent to the risks involved in HEMS operations.
The latter is especially the case when a non-pre-surveyed operating site needs to be used under time

2. In summary — why and what
pressure. Therefore, it was finally decided that other than SAR rescue operations shall fall under the
definition of a HEMS flight.
HEMS rules and alleviations are well suited to the complexity of mountain operations. For safety
reasons, it is preferred to operate different phases of the same mission under the same regulatory
framework with the same alleviations (search, the unknown condition of the people to be rescued,
transportation of support teams of mountain rescuers, etc.).
This NPA proposes amendments to the definition of HEMS in Annex I (Definitions) to the Air OPS
Regulation and in GM1 SPA.HEMS.100 in order to introduce the concept of rescue operations (other
than SAR operations).
2.3.2.2 HEMS operations using the cargo hook and sling
A number of MSs already allow missions that require the use of the cargo hook and sling, under a
HEMS approval, even though the current rules do not foresee this kind of operation. They have
provided AltMoCs to their operators by setting a number of conditions for such operations and by
referring to SPO.SPEC.HEC. This concept is considered valid and should be included in HEMS.
The use of the cargo hook and sling is accepted as an equivalent method to the use of the hoist, to
conduct HEMS operations at locations where landing is not a safe option.
The risks associated to hoist and sling load operations are different. HEMS sling load operations are
subject to risk assessments and specific standard operating procedures.
The use of the helicopter hoist allows the operator to conduct the mission more efficiently, as the
helicopter doesn’t always need to land at an intermediate landing site. The use of the hoist or the sling
should be the operator’s decision that doesn’t need to be biased by regulations.
Using the hoist or the hook and sling both require the help of a technical crew member, but the skills
needed are different. The NPA proposes to introduce the definition of the ‘HEMS HEC technical crew
member’. As the HEMS HEC crew member is needed when the HEMS crew member is not, the number
of crew members need not be increased.
The NPA proposes to create and amend the following in order to enable the use of the cargo hook and
sling for HEMS operations:
— create a new definition of ‘HEMS HEC operations’ in Annex I;
— amend the definition of ‘technical crew member’ in Annex I;
— amend the definition of a ‘HEMS operating site’ in Annex I;
— create new point SPA.HEMS.105;
— create new AMC1 SPA.HEMS.105.
2.3.2.3 Seating of the HEMS technical crew member
It is recognised that the HEMS technical crew member should be sitting at the front in order to assist
the pilot to the best of their abilities. However, in the following cases, this should not be a requirement
and the rules should be simplified:

An agency of the European Union
European Aviation Safety Agency NPA 2018-04
2. In summary — why and what
— For HEMS operations with the use of the cargo hook and sling, the technical crew member is no
longer needed in the front seat after the in-flight reconnaissance of the HEMS operating site and
landing at a nearby intermediate landing site. Help is needed to deal with the sling and supervise
the operation from inside or under the helicopter.
— For HEMS HHO operations, when it is reasonably likely that the hoist is going to be used, the
HEMS HHO technical crew member can assist the pilot and check for obstacles from the HHO
technical crew member’s position in the cabin, and acts as the HHO operator.
After landing at the HEMS operating site, the technical crew member may remain on the ground and
assist the medical team while the commander performs a refuelling flight.
After landing at the HEMS operating site, the technical crew member may remain on the ground to
marshal the helicopter for repositioning purposes.
It is, therefore, proposed to use a more performance-based approach to the seating of the technical
crew member by amending point SPA.HEMS.130 and creating new AMC1 SPA.HEMS.130(e).
2.3.2.4 Oxygen requirements for mountain operations at high altitudes
Helicopters are unpressurised and are usually not equipped with a fixed oxygen installation. At high
altitudes, oxygen supply is required by the Air OPS Regulation. Unlike aeroplanes, helicopters don’t
need to fly at high altitudes in the cruise phase. They only fly at high altitudes temporarily for the
purpose of landing, taking off, hoisting and sling load operations in the mountains. The need for
oxygen is lower, because of the shorter time periods spent at high altitudes, and also because the
physiology of mountain crews tends to adapt to the lower oxygen partial pressure at higher altitudes.
The current helicopter CAT and HEMS oxygen rules are based on aeroplane rules and are deemed too
restrictive for helicopter operations in mountainous areas. Three options are considered to enable
high-altitude helicopter operations in the mountains:
Option 1: Ensure that portable oxygen bottles can be installed on board and used by pilots. This would
mirror the AMC for aeroplane operations, which allows portable equipment as a means of compliance.
It should also be applicable to helicopter CAT and HEMS operations. A number of helicopters with
HEMS equipment installed already have airworthiness-approved oxygen bottles on board to provide
life support to patients. Pilots should be able to use the oxygen from these bottles for high-altitude
operations. The nasal cannula (flexible oxygen hoses bringing oxygen to the nostrils) is considered to
be the preferred oxygen dispenser for HEMS operations. It allows the use of oxygen during the
operation, when necessary, with minimum distraction to the pilot.
Option 2: Enable high-altitude HEMS operations without oxygen on the condition that sufficient
mitigation measures are in place. The current rules for specialised operations in Part-SPO include
mitigations for high-altitude flights between 13 000 and 16 000 ft for flight duration of up to
10 minutes. However, with regard to CAT HEMS operations,
— it is expected that 10 minutes is not enough to cover the duration of a HEMS mission at high
altitudes; also, the safety standards for CAT and HEMS operations are higher than for SPO
operations;
— for HEMS operations, the time duration without oxygen is therefore proposed to be extended to
30 minutes between 10 000 and 16 000 ft to cover the operational needs;

European Aviation Safety Agency NPA 2018-04
2. In summary — why and what
— new mitigations are proposed to be introduced, in addition to the ones in the SPO alleviation,
such as a once-in-a-lifetime hypoxia training;
— the proposed oxygen alleviation deviates from CAT standards in a controlled manner; however,
it is proposed not to be applicable for CAT operations (other than HEMS operations).
Option 3: Align the oxygen requirements for complex helicopters of the CAT and HEMS rules with the
requirements for non-complex helicopter oxygen requirements when it is justified for operational
reasons, because HEMS operations in mountainous areas do not vary significantly with the complexity
of the helicopter. Therefore, HEMS operations with a maximum operating passenger seating
configuration of six or less should be able to use the oxygen requirements that are in place for non-
complex helicopters.
It is proposed to follow all three options. These options do not allow the pilot to plan a lengthy cruise
above 10 000 ft.
The NPA, therefore, proposes a new AMC2 CAT.IDE.H.240 and amendments to SPA.HEMS.110,
AMC1 SPA.HEMS.110(d), and GM1 ORO.GEN.130(b) in order to simplify oxygen rules that are
applicable to helicopters that operate in mountain areas.
2.3.2.5 Helicopter performance requirements for mountain operations at high altitudes
The current generation of twin-engine helicopters that are used in HEMS operations are capable of
operating in PC2 as high as 10 000 ft density altitude with a HEMS configuration and payload. But there
are limited phases of flight at HEMS operating sites (during take-off, landing, hovering disembark,
rescue hoist or sling operations) where it is not possible to comply with PC1 or PC2.
Above this altitude, the HEMS rules cannot be met and patients’ lives remain to be saved.
Although the current HEMS rules may be partly responsible for the helicopter manufacturers’ efforts to
produce twin-engine helicopters with ever higher power margins, it is unlikely that the HEMS market
above 10 000 ft will provide enough an incentive for manufacturers to go much further in this
direction.
It is, therefore, proposed to adjust performance requirements to the reality of high-altitude
operations, and enable the use of category A certified helicopters in PC3 above this altitude for HEMS
operations.
PC3 operations over a hostile environment shall only be conducted when a HEMS operating site used
for take-off, landing or HEMS HEC operations is located above 10 000 ft density altitude and with a
helicopter certified in category A or equivalent, as determined by the Agency, in order to attract the
same CAT HEMS alleviations at the HEMS operating site.
The use of category A or category A equivalent certified helicopters improves safety during the entire
mission from the HEMS base to the HEMS operating site, not only in respect of risk of engine failure,
but also thanks to system redundancy that is not available on category B certified helicopters. In
addition, such helicopters are more suitable platforms for equipment such as helicopter terrain
awareness and warning system (HTAWS), autopilot, flight director, IFR capabilities, etc., that are
important mitigation measures to reduce the risk of loss of reference, collision with obstacles, and loss
of control in flight. See also Section 2.3.3. below.

European Aviation Safety Agency NPA 2018-04
2. In summary — why and what
The NPA proposes the following new rules and amendments to existing rules and AMC in order to
adapt HEMS performance requirements to high-altitude mountain operations, and to mountain-
specific conditions:
— amend CAT.POL.H.420,
— amend SPA.HEMS.125,
— create new AMC1 SPA.HEMS.125(b)(4).
2.3.3. Other than mountain HEMS operations
The NPA proposes new requirements to improve the safety of HEMS operations, especially at night and
in marginal weather conditions, for HEMS operations.
2.3.3.1 Night vision imaging systems (NVIS)
NVIS, when properly used by appropriately trained crew members in a crew concept, is considered to
greatly assist in maintaining situational awareness and in managing risks during night operations.
HEMS without NVIS should be restricted to pre-surveyed operating sites, and to well-lit urban areas.
The NPA proposes to amend SPA.HEMS.100, to create new AMC1 SPA.HEMS.110(b) and new
GM1 SPA.HEMS.100(c) in order to mandate NVIS at night for HEMS operations to unsurveyed sites
outside well-lit urban areas.
2.3.3.2 Obstacle awareness and avoidance
Moving maps with own-ship position, terrain database and obstacle database are considered to be
essential tools for situation awareness and obstacle avoidance. They are proposed to be mandated for
HEMS operations. HTAWS would therefore meet the proposed requirements, but would not be the
only available system to do so.
HTAWS provides terrain proximity warnings, and some models also provide obstacle proximity
warnings, in addition to the above-mentioned features.
However, HTAWS warnings as defined in the current HTAWS standard are not considered to have a
decisive role in terrain and obstacle avoidance. This is due to the amount of nuisance warnings that are
being generated. HTAWS is, therefore, not proposed to be mandated for HEMS operations.
Taking into account that rulemaking task RMT.0708 ‘Controlled flight into terrain (CFIT) prevention
with helicopter terrain avoidance warning systems (HTAWS)’ will reconsider the requirements for
HTAWS, moving maps and other situational awareness devices that will be available in the near future,
it has been decided not to require certified equipment and accept an electronic flight bag (EFB)
application.
The NPA proposes to amend SPA.HEMS.110(b) and to create new AMC1 SPA.HEMS.110(b) to improve
the situational awareness of the pilots regarding the obstacle environment.
2.3.3.3 Simplification of the HEMS operating minima
The NPA proposes to improve and simplify the current version of the HEMS VFR minima, as they are
currently presented in SPA.HEMS.120.
By day, the NPA proposes the merging of the 499–400 and 399–300 ft cloud base categories for
simplification purposes. It was simply not practical for visibility minima to vary every 100 ft.

European Aviation Safety Agency NPA 2018-04
2. In summary — why and what
The NPA proposes to no longer distinguish between single-pilot operations with technical crew
members and two-pilot operations. The distinction was considered not to be adequate, especially
when the technical crew member is sufficiently trained.
The NPA proposes to adapt the HEMS VFR weather minima, following the input of an expert group that
assessed the conditions that experienced and lesser experienced pilots can safely fly into. On average,
this leads to a reduction of the HEMS minima by day, and to a slight increase in the weather minima at
night. At night, the visibility is increased from 2 500–3 000 to 3 000 m visibility with NVIS, and from
2 500–3 000 to 5 000 m visibility without NVIS. 5000 m visibility is actually higher than the visibility
minimum that is sometimes accepted in special VFR (3 000 m), but this is justified since HEMS without
NVIS is a more demanding operation than reaching an aerodrome in a control zone. Also, the 5 000 m
visibility minimum is applicable in combination with a lower ceiling minimum (1 200 instead of
1 500 ft). When the ceiling is higher than 1 500 ft, the visibility minima can be reduced to 3 000 m.
The aim is not to give operational credit to NVIS operations, but to allow reduced visibility in HEMS
operations only if sufficient mitigation measures are in place. By day, the VFR minimum visibility is
averaged out at 1 500 m for dispatch, starting from values of 1 000, 2 000 and 3 000 m. The reduced
VFR minima for day and night can be applied in single-pilot operations provided the HEMS technical
crew member receives sufficient training. The option for the commander to decide to continue a day
flight if the visibility is temporarily reduced, but not below 800 m, is proposed to be kept.
The NPA proposes to replace ‘cloud base’ with ‘ceiling’ for night HEMS VFR minima. This is deemed
useful in particular for weather conditions where FEW clouds would be present at known locations
(coastline, hill tops) without interfering with the flight. In addition, the NPA proposes that dispatch
conditions should be described in the operations manual. Therefore, operators should define precisely
in which particular cases the cloud base may be lower than the minimum ceiling without increasing the
risk.
The requirement to remain clear of clouds when flying VFR is unchanged.
The NPA proposes to amend SPA.HEMS.120 and CAT.POL.H.215, create new AMC1 SPA.HEMS.120(d),
new GM2 SPA.HEMS.120 and new GM1 CAT.POL.H.215(a)(3) in order to simplify the HEMS VFR
minima.
2.3.3.4 Enabling HEMS operations under instrument flight rules (IFR)
HEMS operations can theoretically take place under IFR, but there are a number of restrictions in the
Air OPS Regulation that do not make IFR a practical solution. IFR reverts back to Part-CAT as HEMS
flights are always required to comply with it unless SPA.HEMS provides derogations.
Enabling HEMS operations under IFR often requires the ability to perform part of the flight in VFR and
to make approaches to places other than established aerodromes or heliports. The use of point in
space (PinS) approaches and departures to an initial departure fix (IDF) is therefore needed.
This NPA proposes reduced VFR minima for HEMS operations under IFR using PinS approaches and
departures to an IDF, when the instrument chart instructs the pilot to ‘proceed VFR’.
Depending on the class of airspace and time of day, the ‘proceed VFR’ minima can mean anything from
visibilities of 800 to 5 000 m. When the missed approach point (MAPt) of the PinS approach and the
IDF are very close to the heliport or operating site, the VFR minima may be much higher than needed
for the purpose of achieving a landing or a go-around, especially at night.

European Aviation Safety Agency NPA 2018-04
2. In summary — why and what
The NPA proposes to reduce and simplify the VFR minima for that case, in order to align the minimum
visibility with that needed to complete the procedure.
Note: The following PinS approach enablers are already being addressed in separate rulemaking tasks,
because their use will not be restricted to HEMS operations:
— conditions to comply with the requirements of CAT.OP.MPA.305 when flying an IFR approach to
a location with no aviation weather observations: RMT.0379 ‘All-weather operations’ and
RMT.0573 ‘Fuel procedures and planning’;
— provision of the QNH when flying an IFR approach to a location with no aviation weather
observations, and when the approach chart doesn’t specify the procedure: RMT.0573 ‘Fuel
procedures and planning’;
— dispatch conditions allowing helicopter IFR operations to take place with a single destination
alternate, when flying an IFR approach to a location with no aviation weather forecasts:
RMT.0573 ‘Fuel procedures and planning’; and
— the introduction of operating minima for helicopter PinS approaches into the Air OPS Regulation:
RMT.0379 ‘All-weather operations.
HEMS operations may also use aerodromes. Helicopter specialised operations (SPO) and helicopter
offshore operations (HOFO) can operate IFR to an aerodrome without an alternate. The NPA proposes
to also define the conditions for HEMS operations to operate IFR to an aerodrome without an
alternate.
The NPA proposes to create new SPA.HEMS.122 and GM1 SPA.HEMS.122, to amend CAT.POL.H.215, to
create new GM1 CAT.POL.H.215(a)(1) and (a)(2), and to create new AMC1 SPA.HEMS.120(c) in order to
enable IFR operations for HEMS.
2.3.3.5 Mitigating the risk of loss of visual reference during flight
This NPA proposes to facilitate the use of IFR for HEMS operations. This is a first step towards
mitigating the risk of loss of visual reference during the flight. However, most HEMS operations are
expected to remain under visual flight rules (VFR). The loss of visual reference during a VFR flight
remains one of the major contributors to fatal accidents in HEMS, which calls for the following
amendments:
Increased pilot experience with night HEMS operations: Newly recruited HEMS pilots typically lack
night flight experience. Unfortunately, helicopter night experience can mainly be gained by flying
HEMS.
The minimum night experience required for HEMS is proposed to be marginally increased to take these
factors into account.
Improved IMC training for pilots that do not hold a current instrument rating: The current recency
requirement is deemed too insufficient to achieve sufficient pilot proficiency in dealing with a loss of
visual references during a flight. The 30-minute instrument flight recency is proposed to be replaced by
a structured training session with a minimum duration of 45 minutes and a number of training
elements to be successfully covered during each session.
Stabilisation platforms: It is proposed to require helicopters to be equipped with a basic stability
augmentation system or autopilot for single-pilot operations at night. Higher standards of automation

2. In summary — why and what
for single-pilot operations at night are desirable but may not be achievable at reasonable costs,
whereas the proposal would be sufficiently helpful to the single pilot without excessive disruption to
the current HEMS fleet. It is nonetheless expected that some operators will have to either retrofit their
helicopters or undertake a fleet change. A sufficient time frame of 5 years following the date of
application of the amending regulation is therefore necessary for the successful implementation of
that new requirement.
The NPA proposes to amend SPA.HEMS.110(e), SPA.HEMS.130, and AMC1 SPA.HEMS.130(d), and to
create new AMC1 SPA.HEMS.110(e) in order to mitigate the risk of loss of visual references during VFR
flights.
2.3.3.6 HEMS crew member training and checking
The HEMS technical crew member is considered to be essential to the safety of single-pilot operations.
Rules put emphasis on a crew cooperation concept that is currently not developed in the AMC that
defines the primary tasks of the HEMS crew member or in the AMC that defines the training of the
HEMS crew member.
Feedback from stakeholders shows that the HEMS crew member training and checking varies
significantly among operators. Operators that provide the most advanced training programmes use
line flying under supervision, for which amendments to ORO.TC should be introduced, while operators
that provide the minimum training in accordance with AMC1 SPA.HEMS.130(f) barely comply with the
objectives of the rules. Training is essential considering the variety of backgrounds of the HEMS crew
members, some of which have no aviation knowledge when they are recruited.
The NPA, therefore, proposes to include the reading of checklists into the AMC that defines the
primary tasks of the HEMS technical crew member, in accordance with the rules.
The NPA also proposes to completely restructure the training and checking of HEMS crew members,
taking into account any prior aviation knowledge they might have, and to include the following into the
training and checking programme:
— initial and recurrent training covering the primary tasks of the HEMS crew member;
— additional training and checking reflecting any additional tasks the HEMS crew member may be
assigned, in addition to their primary tasks;
— conversion course ground training and checking when changing helicopter types;
— initial and recurrent aircraft/FSTD training;
— operator proficiency checks;
— line flying under supervision;
— line checks.
In addition, the NPA proposes to consider a HEMS crew member to be inexperienced until they have
flown 50 HEMS missions following the completion of the initial conversion course. Once the
50 missions are flown, the HEMS crew member that changes helicopter types or operators would not
be considered to be inexperienced.

2. In summary — why and what
The NPA, therefore, proposes to amend ORO.TC.110 and ORO.TC.130, to create new GM1 ORO.TC.105,
to amend AMC1 SPA.HEMS.130(e) and AMC1 SPA.HEMS.130(f)(1), and to create new
AMC2 SPA.HEMS.130(f)(1) in order to improve crew cooperation and HEMS crew member training and
checking, and to improve the overall safety of HEMS single-pilot operations.
2.3.3.7 Other minor adjustments to the HEMS rules
The NPA proposes to introduce the following minor adjustments:
— illumination of the HEMS operating site to be better described;
— HEMS dispatch criteria to be included in the operations manual;
— introducing a HEMS tactical risk assessment that may be included in the daily briefing, and
amended as necessary;
— means of observing and recording weather conditions at the HEMS operating base to be defined
in an AMC;
— the current set of considerations for the operation of single-pilot night HEMS with a technical
crew member is proposed to be extended to two-pilot operations, because these considerations
address HEMS operating conditions in general and they remain valid regardless of the crew
composition;
— the ‘aircraft tracking’ wording to be used consistently throughout the Air OPS Regulation;
— the part on the HEMS commander experience to be removed from the implementing rule and
placed in AMC.
The NPA proposes to both amend and create the following, and to delete
AMC1 SPA.HEMS.130(e)(2)(ii)(B) in order to achieve the above-mentioned minor improvements:
— amend SPA.HEMS.130(e)(3);
— amend SPA.HEMS.140;
— amend AMC1 SPA.HEMS.140;
— create new GM1 SPA.HEMS.140(a);
— create new GM1 SPA.HEMS.145(b);
— amend AMC1 SPA.HEMS.130(d).
2.4. What are the expected benefits and drawbacks of the proposals
The impact assessment supports the preferred options regarding PISs and the measures proposed to
mitigates risks related to a degraded visual environment, because they bring important safety benefits.
The impact assessment also supports the preferred options regarding mountain operations.
It was also assessed that no maintenance privilege should be granted to the HEMS technical crew
member.
For the full impact assessment of the alternative options, please refer to Chapter 4.

UNDERLYING PRINCIPLES
(a) General
The original Joint Aviation Authorities (JAA) Appendix 1 to JAR-OPS 3.005(i) was introduced in
January 2002 to address problems that had been encountered by Member States at hospital
sites due to the applicable performance requirements of JAR-OPS 3 Subparts G and H. These
problems were enumerated in ACJ to Appendix 1 to JAR-OPS 3.005(d) paragraph 8, part of
which is reproduced below.
‘8 Problems with hospital sites
During implementation of JAR-OPS 3, it was established that a number of States had
encountered problems with the impact of performance rules where helicopters were
operated for HEMS. Although States accept that progress should be made towards
operations where risks associated with a critical power unit failure are eliminated, or

3. Proposed amendments and rationale in detail
limited by the exposure time concept, a number of landing sites exist which do not (or
never can) allow operations to performance class 1 or 2 requirements.
These sites are generally found in a congested hostile environment:
- in the grounds of hospitals; or
- on hospital buildings;
The problem of hospital sites is mainly historical and, whilst the Authority could insist that
such sites not be used - or used at such a low weight that critical power unit failure
performance is assured, it would seriously curtail a number of existing operations.
Even though the rule for the use of such sites in hospital grounds for HEMS operations
(Appendix 1 to JAR-OPS 3.005(d) sub-paragraph (c)(2)(i)(A)) attracts alleviation until 2005,
it is only partial and will still impact upon present operations.
Because such operations are performed in the public interest, it was felt that the Authority
should be able to exercise its discretion so as to allow continued use of such sites provided
that it is satisfied that an adequate level of safety can be maintained - notwithstanding
that the site does not allow operations to performance class 1 or 2 standards. However, it
is in the interest of continuing improvements in safety that the alleviation of such
operations be constrained to existing sites, and for a limited period.’
As stated in this ACJ and embodied in the text of the appendix, the solution was short-term
(until 31 December 2004). During the commenting period of JAA NPA 18, representations were
made to the JAA that the alleviation should be extended to 2009. The review committee, in not
accepting this request, had in mind that this was a short-term solution to address an immediate
problem, and a permanent solution should be sought.
[…]
(d) Long-term solution
Although not offering a complete solution, it was felt that a significant increase in safety could
be achieved by applying an additional performance margin to such operations. This solution
allowed the time restriction of 2004 to be removed.
(1) The derogation provided for by Article 6.6 of Regulation (EU) No 965/2012, which allows
Member States to approve public interest sites under their own conditions, was meant to
be a temporary transitional arrangement. This transitional arrangement was only
intended to allow the continuation of existing sites. For this reason, any newly approved
public interest sites that have been established since 28 October 2014 will have to be
phased out by 2022.
(2) No mandatory phase-out is foreseen for approved sites that were established as public
interest sites before 28 October 2014.
(3) A public interest site should be considered to be established at the time when it was
operated in the public interest for the first time.
(4) As of the ‘date of entry into force of this amendment’ there should be no more approvals
of public interest sites that were established after 28 October 2014, in accordance with
point ARO.OPS.220(c).
(5) As of the ‘date of entry into force of this amendment’ the obstacle environment at
approved public interest sites should be kept under check in order to avoid performance
class 1 operations to be further hindered, in accordance with point ARO.OPS.220(d).

Table 1. Duration of public interest site approvals
Date on which the Maximum duration
approved PIS was of the PIS approval
established
Before 28.10.2014 Unlimited duration, provided
there is no permanent worsening
of the obstacle environment.
After 28.10.2014 PIS approval to expire by
31.7.2022.
(6) Since a number of hospital sites may remain approved public interest sites in the
foreseeable future, it was considered important to keep minimum performance margins
when operating these sites.
(i) The required performance level of 8 % climb gradient in the first segment required
by point CAT.POL.H.225(a)(5) reflects ICAO Annex 14 Volume II in ‘Table 4-3
'Dimensions and slopes of obstacle limitations surfaces’ for performance class 2.
It was established as a means of mitigating performance issues. This requirement is
retained as it defines a proportionate mass penalty at such sites, thereby applying
an additional performance margin to such operations.
(ii) The performance delta is achieved without the provision of further manufacturer’s
data by using existing graphs to provide the reduced take-off mass (RTOM).
(iii) If the solution in relation to the original problem is examined, the effects can be
seen.
(A1) Solution with relation to (c)(1): although the problem still exists, the safest
procedure is a dynamic take-off reducing the time taken to achieve Vstayup and thus
allowing VFR recovery — if the failure occurs at or after Vy and 200 ft, an IFR recovery
is possible.
(B2) Solution with relation to (c)(2): as in (c)(1) above.
(C3) Solution with relation to (c)(3): once again, this does not give a complete
solution;, however, the performance delta minimises the time during which a climb
over the obstacle cannot be achieved.
4. AMC2 CAT.IDE.H.240 is added as follows:

OXYGEN STORAGE AND DISPENSING EQUIPMENT
(a) Supplemental oxygen requirements may be met either by means of installed or portable
equipment.
(b) The use of oxygen dispensers should not prevent the crew from performing their intended tasks,
including any radio communications.
(c) The oxygen-dispensing unit should be approved in accordance with Commission Regulation (EU)
No 748/2012 and may consist in a nasal oxygen cannula.

THE HEMS PHILOSOPHY
(a) Introduction
This GM outlines the HEMS philosophy. Starting with a description of acceptable risk and
introducing a taxonomy used in other industries, it describes how risk has been addressed in this
Subpart to provide a system of safety to the appropriate standard. It discusses the difference
between HEMS and air ambulance -— in regulatory terms. It also discusses the application of
operations to public interest sites in the HEMS context.
Following the extension of the definition of HEMS to rescue operations other than search and
rescue (SAR), this GM also discusses rescue operations.
Crisis situations are not HEMS. They can affect a large number of people at the same time. Such
operations are conducted under national regulations and are therefore not discussed.
(b) Acceptable risk
The broad aim of any aviation legislation is to permit the widest spectrum of operations with the
minimum risk. In fact, it may be worth considering who/what is at risk and who/what is being
protected. In this view, three groups are being protected:
(1) third parties (including property) — highest protection;
(2) passengers (including patients); and
(3) crew members (including technical crew members) — lowest protection.
It is for the Llegislator to facilitate a method for the assessment of risk — or as it is more
commonly known, safety management (refer to Part-ORO).
(c) Risk management
Safety management textbooks8 describe four different approaches to the management of risk.
All but the first have been used in the production of this section and, if it is considered that the

3. Proposed amendments and rationale in detail
engine failure accountability of performance class 1 equates to zero risk, then all four are used
(this of course is not strictly true as there are a number of helicopter parts, - such as the tail
rotor which, due to a lack of redundancy, cannot satisfy the criteria):
(1) Applying the taxonomy to HEMS gives:
(i) zero risk; no risk of accident with a harmful consequence –— performance class 1
(within the qualification stated above) -— the HEMS operating base;
(ii) de minimis; minimised to an acceptable safety target -— for example, the exposure
time concept where the target is less than 5 ×x 10-8 (in the case of elevated final
approach and take-off areas (elevated FATOs) at hospitals in a congested hostile
environment the risk is contained to the deck edge strike case -— and so in effect
minimised to an exposure of seconds);
(iii) comparative risk; comparison to other exposure -— the carriage of a patient with a
spinal injury in an ambulance that is subject to ground effect compared to the risk
of a HEMS flight (consequential and comparative risk);
(iv) as low as reasonably practicable; where additional controls are not economically or
reasonably practicable -— operations at the HEMS operating site (the accident
site).
(2) HEMS operations are conducted in accordance with the requirements contained in
Annex IV (Part-CAT) and Annex III (Part-ORO), except for the variations contained in
SPA.HEMS, for which a specific approval is required. In simple terms, there are three
areas in HEMS operations where risk, beyond that allowed in Part-CAT and Part-ORO, are
identified and related risks accepted:
(i) in the en-route phase, where alleviation is given from height and visibility rules;
(ii) at the accident site, where alleviation is given from the performance and size
requirement; and
(iii) at an elevated hospital site in a congested hostile environment, where alleviation is
given from the deck edge strike -— provideding elements of the CAT.POL.H.305 are
satisfied.
In mitigation against these additional and considered risks, experience levels are
set, specialist training is required (such as instrument training to compensate for
the increased risk of inadvertent entry into cloud), and operation with two crew
(two pilots, or one pilot and a HEMS technical crew member) is mandated.
(HEMS crews and medical passengers are also expected to operate in accordance
with good crew resource management (CRM) principles.)
(d) Additional mountain-specific considerations
It was considered necessary to enable sling load operations under HEMS, in addition to the
hoist. Environmental, equipment or organisational conditions may lead operators to choose
either the external hoist or cargo hook operation, based on a risk assessment.
In order to enable HEMS operations at all altitudes, HEMS operations under performance class 3
have been authorised under the following conditions: operations over a hostile environment
should only be conducted when a HEMS operating site used for take-off, landing or HEMS HEC
operations is located above 10 000 ft density altitude and with a helicopter certified as
category A or equivalent as defined by the Agency, in order to attract the same CAT HEMS
alleviations at the HEMS operating site.

European Aviation Safety Agency NPA 2018-04
3. Proposed amendments and rationale in detail
The use of category A or equivalent helicopters improves safety during the entire mission, not
only in respect of risk of engine failure, but also because of the available system redundancies.
Moreover, such helicopters are more suitable for equipment such as HTAWS, autopilot, flight
director, IFR capabilities, etc., that are important mitigations measures to reduce the risk of loss
of reference, collision with obstacles, and loss of control in flight.
(de) Air ambulance
In regulatory terms, air ambulance is considered to be a normal transport task where the risk is
no higher than for commercial air transport operations under Part-CAT and to the full OPS.CAT
and Part-OROcompliance. This is not intended to contradict/complement medical terminology
but is simply a statement of policy; none of the risk elements of HEMS should be extant and
therefore none of the additional requirements of HEMS need to be applied.
To provide a road ambulance analogy:
(1) if called to an emergency: an ambulance would proceed at great speed, sounding its siren
and proceeding against traffic lights -— thus matching the risk of operation to the risk of a
potential death (= HEMS operations);
(2) for a transfer of a patient (or equipment) where life and death (or consequential injury of
ground transport) is not an issue: the journey would be conducted without sirens and
within normal rules of motoring -— once again matching the risk to the task (= air
ambulance operations).
The underlying principle is that the aviation risk should be proportionate to the task.
It is for the medical professional to decide between HEMS or air ambulance -— not the pilot. For
that reason, medical staff who undertake to task medical sorties should be fully aware of the
additional risks that are (potentially) present under HEMS operations (and the prerequisite for
the operator to hold a HEMS approval). (For example, in some countries, hospitals have
principal and alternative sites. The patient may be landed at the safer alternative site (usually in
the grounds of the hospital) thus eliminating risk -— against the small inconvenience of a short
ambulance transfer from the site to the hospital.)
Once the decision between HEMS or air ambulance has been taken by the medical professional,
the commander makes an operational judgement over the conduct of the flight.
Simplistically, the above type of air ambulance operations could be conducted by any operator
holding an Air Operator Certificate (AOC) (HEMS operators hold an AOC) — and usually are
conducted when the carriage of medical supplies (equipment, blood, organs, drugs, etc.) is
undertaken and when urgency is not an issue.
Regarding other than SAR rescue operations, if a person is endangered by the environment
without a medical condition, then a helicopter may be needed. Such danger may arise, for
instance, from temperature, wind, or snow. The same principles should apply when the person’s
life is not immediately endangered by the situation, however action is required, the flight is
considered to be a normal transport task where the risk is not higher than for commercial air
transport operations under Part-CAT and Part-ORO. None of the additional requirements of
HEMS need to be applied. Such a rescue operation may also be conducted by a HEMS operator.
When the medical condition of the person is not known in advance, in a situation of time
pressure, then this rescue operation is part of the definition of HEMS.

3. Proposed amendments and rationale in detail
There are only two possibilities: transportation as passengers or cargo under the full auspices of
OPS.CAT and Part-ORO (this does not permit any of the alleviations of SPA.HEMS -— landing and
take-off performance should be in compliance with the performance Subparts of Part-CAT), or
operations under a HEMS approval as contained in this Subpart.
(fg) HEMS operational sites
The HEMS philosophy attributes the appropriate levels of risk for each operational site; this is
derived from practical considerations and in consideration of the probability of use. The risk is
expected to be inversely proportional to the amount of use of the site. The types of sites are as
follows:
(1) HEMS operating base: from which all operations will start and finish. There is a high
probability of a large number of take-offs and landings at this HEMS operating base and
for that reason no alleviation from the operating procedures or performance rules are
contained in this Subpart.
(2) HEMS operating site: because this is the primary pick-up site related to an incident or
accident, its use can never be preplanned and therefore attracts alleviations from
operating procedures and performance rules, when appropriate.
(3) Additional HEMS operating site: each HEMS mission is different, especially in
mountainous areas where the crew and helicopter need to adapt to different conditions.
High altitude, unstable wind conditions, degraded vision, and difficult terrain are some of
the characteristics of HEMs operations. Sometimes, the mission requires an additional
HEMS operating site to be used, due to performance issues (weight reduction by
unloading equipment), for hook preparation and stowage, or for dispatching ground
rescue units when the accident or rescue site is not reachable.
(34) The hospital site: is usually at ground level in hospital grounds or, if elevated, on a
hospital building. It may have been established during a period when performance criteria
were not a consideration. The amount of use of such sites depends on their location and
their facilities; normally, it will be greater than that of the HEMS operating site but less
than for a HEMS operating base. Such sites attract some alleviation under this Subpart.
(gh) Problems with hospital sites are explained described in GM1 CAT.POL.H.225.
During implementation of the original HEMS rules contained in JAR-OPS 3, it was established
that a number of States had encountered problems with the impact of performance rules where
helicopters were operated for HEMS. Although States accept that progress should be made
towards operations where risks associated with a critical engine failure are eliminated, or
limited by the exposure time concept, a number of landing sites exist that do not (or never can)
allow operations to performance class 1 or 2 requirements.
These sites are generally found in a congested hostile environment:
(1) in the grounds of hospitals; or
(2) on hospital buildings.
The problem of hospital sites is mainly historical and, whilst the authority could insist that
such sites are not used – or used at such a low weight that critical engine failure
performance is assured – it would seriously curtail a number of existing operations.
Even though the rule for the use of such sites in hospital grounds for HEMS operations
attracts alleviation, it is only partial and will still impact upon present operations.

3. Proposed amendments and rationale in detail
Because such operations are performed in the public interest, it was felt that the
authority should be able to exercise its discretion so as to allow continued use of such
sites provided that it is satisfied that an adequate level of safety can be maintained -
notwithstanding that the site does not allow operations to performance class 1 or 2
standards. However, it is in the interest of continuing improvements in safety that the
alleviation of such operations be constrained to existing sites, and for a limited period.
It is felt that the use of public interest sites should be controlled. This will require that a
State directory of sites be kept and approval given only when the operator has an entry in
the route manual section of the operations manual.
The directory (and the entry in the operations manual) should contain for each approved
site:
(i) the dimensions;
(ii) any non-conformance with ICAO Annex 14;
(iii) the main risks; and
(iv) the contingency plan should an incident occur.
Each entry should also contain a diagram (or annotated photograph) showing the main aspects
of the site.

When a HEMS operating base that is intended to be used for night operations is at a location without
weather reporting, the operator should have means for observing and recording local weather
conditions, including cloud base and visibility from the HEMS operating base.

4.1. Public interest sites (PISs)
The issues to be addressed are described in Chapter 2.1.1.
4.1.1. Who is affected
Hospitals, health authorities, NAAs, operators, pilots, and authorities in charge of building permissions
could be affected by the amendments to the rules regarding PISs.
4.1.2. How could the issue/problem evolve
With the current set of rules and regulations:
— PIS derogations should be dealing with historical sites only. It seems that PIS derogations are
being used not only to continue the use of existing sites, but also to deviate from the helicopter
performance rules for new hospital sites that are coming into service.
— Hospitals are constructing new buildings continuously;
— At PISs, there is an opportunity to create new rooftop helipads with sufficient dimensions and
obstacle clearance every time a new building is constructed at the hospital site. This would allow
to terminate the PIS derogation and to improve safety. These opportunities are often missed
because there is no incentive to improve PISs and no deadline to phase out the current
derogations;
— At hospital sites that can be operated under performance class 1 (PC1), the current rules do not
prevent helicopter flight paths to be obstructed by new buildings and obstacles. In some MSs,
there are no other schemes to prevent helicopter flight paths from being obstructed by new
obstacles.
If this happens, and the hospital landing site existed before 2002 or 2014, it may become a PIS;
— It is likely that in the future there will be more PISs, and not less, because of the changing
obstacle environment at hospitals;
— For the same reason, it is likely that the obstacle environment will worsen at PISs, instead of
improving towards compatibility with the helicopter performance requirements;
— The PIS rules are likely to become a global exemption from the performance requirements at
hospital sites in some MSs, with a high cost to safety.
4.1.3. What we want to achieve
The objectives are already included in Section 2.2. Furthermore, this detailed issue is related to the
following specific objective:
— to ensure that the trend described in Section 4.1.2 above is reversed, ensure that there are no
new PISs, and that the obstacle environment does not worsen at existing PISs.

4.1.4. How it could be achieved — options
The options that have been analysed are the following:
Option No Description
0 No policy change (no change to the rules; risks remain as outlined in the
issue analysis).
1 Amend the PIS rules as proposed.
Discarded options:
A number of options had already been considered during the consultation of the related concept paper
and have been discarded. These options were the following:
— The option to phase out the categories of PISs, or all PISs, by 2022 or later: it was considered
that there would be no viable alternative at some hospital sites, and this would invite new
exemptions and derogations to be filed;
— The option to use safety promotion at European level only: the conflicting interests are too
important between the aviation industry, the health industry and the authorities in charge of
building permissions. Safety promotion would not work. Safety promotion at national level, as
adapted to local circumstances, may be useful in addition to EASA rulemaking.
4.1.5. Applied methodology
The methodology applied to this RIA is the multi-criteria analysis (MCA), which allows comparing all the
options by scoring them against a set of criteria.
The MCA covers a wide range of techniques that aim to combine a variety of positive and negative
impacts into a single framework to allow an easier comparison of scenarios.
The MCA key steps for this RIA include the following:
— establishing the criteria to be used for comparing the options (these criteria must be
measurable, at least in qualitative terms);
— scoring how well each option meets the criteria (the scoring needs to be relative to the baseline
scenario);
— ranking the options by combining their scores.
The criteria used to compare the options were derived from the Basic Regulation and the guidelines for
the RIA. The principal objective of EASA is to ‘establish and maintain a high uniform level of safety’, in
accordance with Article 2(1) of the Basic Regulation. Additionally, the Basic Regulation identifies
environmental, economic, social, and proportionality objectives.
For the scoring of the impacts, a scale of – 5 to + 5 is used to indicate the negative and positive impacts
of each option (i.e. from ‘very high’ to ‘very low’ negative/positive impacts). The intermediate levels of
benefits are termed ‘high’, ‘medium’ and ‘low’, providing a total of five levels in each direction (five in
the positive and five in the negative one), with a ‘no impact’ score also being possible.

This methodology applies as well to the options analysed for the other issues that are discussed in this
NPA.
Option 0 (no change) is assessed in each paragraph of the impact assessment. The other options are
numbered as follows: The topic number, followed by a letter if several options are proposed in a
defined topic. Option 2a is option ‘a’ of topic number 2.
4.1.6. Public interest sites (PISs) — analysis of impacts
4.1.6.1 Public interest sites (PISs) — safety impact
Option 0: Compared to the current situation, negative safety impacts in some MSs are expected if no
action is taken, as already mentioned in Section 4.1.2 above.
Option 1: Amending the rules will improve the current safety issue.
4.1.6.2 Public interest sites (PISs) — social impact
Option 0 and Option 1: the social impact is deemed to be negligible for both options because health
services should not be impacted.
4.1.6.3 Public interest sites (PISs) — economic impact
Option 0: No impacts expected.
Option 1: With Option 1, authorities will face higher costs due to the need for a larger workforce
(including NAAs and authorities in charge of building permissions) to ensure that the obstacle
environment does not worsen at PISs. Hospitals located in congested hostile areas and that wish to
receive HEMS helicopter traffic will also need to better control the obstacle environment at the
helicopter landing site, potentially with the help of authorities in charge of building permissions.
A very low negative economic impact is, therefore, expected.
4.1.6.4 Public interest sites (PISs) — conclusion
Column 1 Option 0 Option 1
No change NPA proposal
Safety impact –1 +3
Social impact 0 0
Economic impact 0 –1
TOTAL –1 +2
Based on the impacts, the conclusion can be drawn that Option 1 is clearly supported by the impact
assessment. The following question will help to better assess the scale of the issue.
Question to NAAs:
— How many PISs are approved in your territory?
— If the rules don’t change, do you expect the number of approved PISs to increase or decrease in
the next 5 years?
— What would be the percentage?

4.2. Mountain HEMS operations and rescue operations other than SAR operations
The issue to be addressed is described in Section 2.1.2.
4.2.1. Who is affected
Hospitals, health authorities, NAAs, operators, and pilots could be affected by the amendments to the
rules regarding mountain operations.
4.2.2. How could the issue/problem evolve
The lack of harmonisation across Europe and the use of potentially competing national rules could
drive a race towards deregulations.
4.2.3. What we want to achieve
The objectives are already included in Section 2.2. Furthermore, this detailed issue is related to the
following specific objective:
— to provide a proportionate framework for mountain HEMS and rescue operations other than SAR
operations.
4.2.4. How it could be achieved — options
The options that have been considered are the following:
Option No Description
0 No policy change (no change to the rules; risks remain as outlined in
the issue analysis).
2a Include mountain HEMS operations and rescue operations other than
SAR operations in the rules, and introduce the use of the cargo sling
in HEMS operations.
2b Introduce performance and oxygen alleviations for mountain HEMS
operations.
2c Make the rules on the seating of the HEMS crew member more
performance-based.
Discarded options:
A number of options had already been considered during the consultation of the related concept paper
and have been discarded. These options were the following:
— The option to consider all HEMS activities as state or similar services was not considered to be
the way forward by a number of stakeholders that are in favour of European regulations;
— The option to consider HEMS activities as part of SPO to better include mountain and rescue
operations: this option was considered to be unsafe by the majority of the stakeholders;
— The option to introduce flexibility provisions was not considered to be useful, as these already
exist in the Basic Regulation) and are highly likely to remain in the new Basic Regulation.

4.2.5. Mountain HEMS operations and rescue operations other than SAR operations — analysis of impacts
4.2.5.1 Mountain HEMS operations and rescue operations other than SAR operations — safety impact
Option 0: No impact expected.
Option 2: The oxygen part of Option 2b introduces alleviations to the rules, together with a number of
mitigations on the safety side. The alleviation results in oxygen rules that are possible to be complied
with, instead of the current rules which are simply disregarded. The mitigations that are introduced
have a positive safety impact as they are now much more oriented to the characteristics of mountain
HEMS and rescue operations.
The performance part of Option 2b proposes to align the rules with the capabilities of high-
performance twin-engined helicopters, in order to allow the operation of a whole mission under the
same regulatory framework.
In addition, the use of Category A or Category A equivalent helicopters is an alignment with current
practice and avoids a reduction of safety during the entire HEMS mission that would take place if
Category B helicopters were operated in HEMS.
Category A helicopters appear to be safer, not only in respect of risk of engine failure and other failures
due to system redundancy.
In case rescue operations (other than HEMS) are operated with single-engined helicopters, the
combination of Option 2a and Option 2b has a significant positive impact on safety because Category A
helicopters will be operated instead.
Option 2c is designed to have a negligible safety impact.
Overall, Option 2 is expected to have a positive safety impact compared to Option 0 because it will
extend the scope of HEMS operations where it is reasonable to do so, while defining the best practice
for the use of the cargo sling.
4.2.5.2 Mountain HEMS operations and rescue operations other than SAR operations — social impact
Option 0: No impact expected.
Option 2: The alleviations introduced in Options 2a and 2b ensure that more, or at least an equal
number of mountain HEMS and rescue operations can be performed.
For authorities, the impact would be positive, as the introduction of harmonised European regulations
will allow competent authorities which wish to do so to adopt them instead of developing national
regulations and alternative means of compliance. The impact on authorities is therefore positive.
Option 2c has no social impact.
4.2.5.3 Mountain HEMS operations and rescue operations other than SAR operations — economic impact
Option 0: No impact expected.
Option 2: The investments required when introducing the new rules as detailed in Option 2a and 2b
are considered to be rather limited compared to Option 0. The new rules are mainly the result of
adjusting them to the everyday practice that is currently in place for HEMS operations in different MSs.
However, the economic impact of Option 2b will not be negligible for a small number of operators:

European Aviation Safety Agency NPA 2018-04
4. Impact assessment (IA)
— In case other than HEMS rescue operations are conducted with single-engined helicopters, the
combination of Option 2a and 2b has a significant negative impact because operators will have
to invest in Category A certified helicopters with significantly higher operating and capital costs.
This negative economic impact is partly offset by the capability of Category A certified helicopters to
complete the entire mission, thus avoiding the inefficiency of a rendezvous system.
— A small number of twin-engined helicopters used in HEMS in the mountains may not be capable
of the helicopter performance required at high altitudes close to 10 000 ft density altitude
(the proposed requirements being based on the performance of recent helicopters such as the
EC135 T3 and the AW109 SP). As the number of helicopters concerned is considered to be small,
and no change in helicopter type is expected (only variants), the economic impact is limited.
Oxygen part of Option 2b: as oxygen is already needed for medical purposes in most HEMS helicopters,
the economic costs of an approved oxygen storage and dispensing unit are considered to be very low.
If costs are higher than expected in specific circumstances, operators can also choose not to carry
oxygen on high-altitude HEMS and rescue operations using the oxygen alleviation, in which case the
highest costs come from a once-in-a-lifetime hypoxia training for each pilot.
Option 2c: the proposal allows HEMS HHO operations to be conducted with one crew member less in
specific cases. This has a positive economic impact.
From the perspective of a level playing field across Europe, the introduction of harmonised European
rules with Options 2a, 2b and 2c is considered to be positive. Cross-border cooperation in mountain
areas may also benefit from harmonised European rules.

Question to helicopter operators that conduct mountain operations at high altitudes (8 000 ft or
higher):
— Will you be affected by the EASA helicopter performance rules if they are to be applied for
mountain operations?
— Is your fleet capable of meeting the proposed helicopter performance requirements to the highest
altitudes in your area, up to 10 000 ft density altitude?
— If not, how much will it cost to adapt your fleet?
Question to helicopter operators that conduct other than SAR rescue operations:
— How many helicopters in your fleet are engaged in such operations?
— Do you operate such missions with single-engine or twin-engine helicopters?
— If you use single-engine helicopters, how many of them will need to be replaced by twins?
— How much will it cost: Fixed costs? Recurrent costs?

4.3. Other than mountain HEMS operations
The issue to be addressed is described in Section 2.1.3.
4.3.1. Who is affected
Hospitals, health authorities, NAAs, operators, and pilots could be affected by the amendments to the
rules regarding HEMS operations.
4.3.2. How could the issue/problem evolve
As already discussed in Section 2.1 and 2.1.3, HEMS is an activity that is prone to risk-taking.
Available accident data indicates that the current rules do not sufficiently ensure the safe execution of
this type of flights, especially during night and in marginal weather conditions. Several MSs have
developed additional requirements in order to mitigate shortcomings in the current rules.
4.3.3. What we want to achieve
The objectives are already included in Section 2.2. Furthermore, this detailed issue is related to the
following specific objective:
— to improve the safety of HEMS operations, especially at night and in marginal weather conditions.

4.3.4. How it could be achieved — options
The following Options 3a to 3e were developed and analysed in the current working groups, while
Option 4 had been previously identified as valid during previous rulemaking group sessions:
Option No Short title Description
0 No policy change.
3a Improve the situational awareness of pilots regarding the obstacle
environment during night flights by introducing the requirement of having a
device available with a moving map display, providing own-ship position and
obstacles.
3b Simplify the HEMS VFR minima by day and night:
Merging the visibility minima for 499–400 ft and 399–300 ft ceiling and for one
or two pilots.
Changing cloud base for ceiling.
Slightly increasing visibility minima at night.
Making alleviations accessible only to operators with NVIS equipment and full
technical crew member training.
3c Enable IFR operations in HEMS by introducing the possibility of reduced HEMS
operating minima when instructed to ‘proceed VFR’ following an instrument
approach or when instructed to ‘proceed VFR’ prior to an IFR departure.
3d Enhance crew training requirements by increasing the minimum required pilot
experience for HEMS flights during night, by improving IFR training for pilots
that not hold a current IR, and better define HEMS technical crew member
training and checking.
3e Require the helicopter to be equipped with a basic stability augmentation
system or autopilot for single-pilot operations at night.
4 Mandate NVIS at night for HEMS operations to non-pre-surveyed operating
sites outside well-illuminated built-up areas.
Discarded options:
A number of options had already been considered during the consultation of the related concept
paper. The introduction of HTAWS was not supported, and dry weather was not considered a good
enough mitigation measure to address the current safety risks in HEMS operations. These options
were, therefore, discarded.
4.3.5. Other than mountain HEMS operations — analysis of impacts
4.3.5.1 Other than mountain HEMS operations — safety impact
Option 0: No impacts expected.
Option 3: Option 3a, improving the situational awareness by means of requiring a device with a moving
map display and providing information regarding own-ship position and obstacles, mitigates the risk of
collisions with these obstacles. The safety impact is, therefore, considered to be significantly positive.
The safety impact of Option 3b is the following:

Proprietary document. Copies are not controlled. Confirm revision status through the EASA intranet/internet. Page 64 of 72
An agency of the European Union
European Aviation Safety Agency NPA 2018-04
4. Impact assessment (IA)
— Increasing minima from 1 000 to 1 500 m for two-pilot operations by day, and increasing minima
from 2 500 to 3 000 m for two-pilot operations by night: positive safety impact.
— Reducing minima from 2 000/3 000 to 1 500 m by day for other kinds of operations: the negative
safety impact is partially mitigated by means of improving IMC training for pilots that do not
hold a current IR (Option 3d).
— Making the HEMS reduced minima only accessible with full HEMS crew member training (in
combination with Option 3d) and NVIS equipment: positive safety impact.
Therefore, the overall safety impact of Option 3b is positive by night and negative by day. The negative
impact by day can be offset by Option 3d.
Option 3c, enabling IFR operations in HEMS by introducing the possibility of reduced HEMS operating
minima when instructed to ‘proceed VFR’ following an instrument approach or when instructed to
‘proceed VFR’ prior to an IFR departure, covers a new set of rules following the latest developments
regarding the use of point in space (PinS) approaches and departures to an initial departure fix (IDF).
Option 3c proposes reduced VFR minima for HEMS operations under IFR using PinS approaches and
depatures to an IDF with ‘proceed VFR’. The reason for this is that when the missed approach point
(MAPt) of the PinS approach and the IDF are very close to the heliport or operating site, the VFR
minima may be much higher than needed for the purpose of achieving a landing or a go-around,
especially at night. The aim is to align the VFR minima with the visibility needed to complete the
procedure. Taking into account the fact that in order to execute these flights the pilot needs to hold a
current IR, that Option 3d increases the pilot experience requirements for night HEMS, and that Option
3e requires helicopters to be equipped with a basic stability augmentation system or autopilot for
single-pilot operations at night, it can be concluded that the negative safety impacts of Option 3c, if
any, are sufficiently mitigated.
Option 3d is all about further enhancing crew training requirements by increasing the minimum
required pilot experience for HEMS flights during night, by improving IFR training for pilots that do not
hold a current IR, and by further improving the training of HEMS technical crew members. The aim is to
mitigate the risk related to a loss of visual reference, and to reduce pilot workload by introducing crew
coordination concepts. Compared to Option 0, Option 3d will have a positive safety impact and can be
further enhanced by the implementation of Option 3e.
The loss of visual reference has been identified as one of the most important root causes of HEMS
accidents/serious incidents over the past 10 years. Option 3e, like Option 3d, aims to mitigate this risk
by requiring helicopters to be equipped with a basic stability augmentation system or autopilot for
single-pilot operations at night. Higher standards of automation for single-pilot operations at night are
desirable in order to achieve a significant reduction in workload. Basic handling of the helicopter will
require less attention, resulting in more time available to deal with the loss of visual reference.
Alternatively, an operator can choose to perform night HEMS flights with two pilots. With two pilots,
one can be assigned the task of handling the helicopter while the other would be dealing with the loss
of visual reference. The safety impact of this option is considered to be significant.
Option 4: NVIS.
Mandating NVIS at night for HEMS operations at non-pre-surveyed operating sites outside well-lit
areas will significantly improve the safety of HEMS operations at night.

European Aviation Safety Agency NPA 2018-04
4. Impact assessment (IA)
Night HEMS operations to pre-surveyed areas will remain possible, provided the obstacle data
regarding such sites is updated on a regular basis. This will also improve the safety of HEMS flights
without NVIS.
4.3.5.2 Other than mountain HEMS operations — social impact
Option 0 and Option 4: No impacts expected.
Option 3: Option 3a will not directly influence the number of flights being executed, as it primarily aims
to reduce the risk of collision with obstacles. The same applies to Option 3d, as this option is solely
related to experience and training.
The social impact of Options 3b and 3c is positive, as it is expected that both options make it possible
to execute more HEMS flights compared to Option 0. Health services will benefit from the increased
reliability of HEMS flights.
Option 3e has no direct impact on the number of HEMS flights, unless the costs related to this option
are so high, that health services in some MSs will no longer be able to afford helicopter services.
The probability that this would happen is kept very low by a 5-year implementation time frame, and is
therefore considered negligible.
The impact of Options 3a, 3d, and 3e on competent authorities is considered to be positive, as there
will be no need any more for alternative means of compliance and operational directives. This will also
improve the level playing field.
4.3.5.3 Other than mountain HEMS operations — economic impact
Option 0: No impacts expected.
Option 4: The economic impact of Option 4 is limited because a low-cost alternative to NVIS is
provided. Operators may elect to operate at night without NVIS. In this case, they should instead keep
a directory of pre-surveyed operating sites outside well-lit built-up areas. The regular update of this
directory generates costs that are considered to be negligible.
Option 3: The economic impact of Option 3a is considered to be negative, as investments have to be
made to equip helicopters with the proposed function. However, the costs are reduced by the option
to use electronic flight bags (EFBs).
The economic impact of Option 3b is positive for daytime operations, as the minima are lowered, but
negative for night-time operations because investments are necessary to benefit from lower NVIS
operating minima. If the operator opts not to invest in NVIS, then the operating minima are increased
compared to Option 0 and this might have a negative impact on the number of flights being executed.
On average, the economic impact of Option 3b is considered to be slightly negative compared to that
of Option 0.
Option 3c is only applicable when operators want to benefit from the possibilities it offers. If operators
do not want this, no additional investments are necessary and the situation is comparable to that of
Option 0. Therefore, the economic impact is assessed to be neutral.
Option 3d requires investments in training. The cost of additional flight crew member training is
considered to be limited. The cost of additional training of HEMS technical crew members will heavily

depend on current practices by the different operators. For some operators, there will be no or limited
economic impact, while for others the investment will be larger.
Option 3e requires significant investments. It could even lead to a situation where certain helicopters
currently being used for HEMS flights will have to be replaced, if two-pilot operations are not
considered, and if the fitting of a stability augmentation system or autopilot on the existing helicopter
is not practical, too costly, or if the additional mass reduces the payload too much.
A short study of the HEMS fleet indicates that very few of the oldest HEMS helicopters are likely not to
comply with Option 3e. The 5-year implementation period is proposed to reduce the economic impact
of this measure, as many of these older helicopters will become obsolete regardless of the proposed
change. The economic impact of Option 3e remains significantly negative.

Conclusion: Considering the consensus between industry, authorities and pilot associations to improve
the safety of HEMS operations, and also considering that the safety impact should weigh more than
the other factors, the impact assessment supports the NPA proposal to combine all the above-
mentioned options.
The following questions will help to better assess the costs and benefits of Option 3e.

— How many helicopters does your fleet comprise?
— How many helicopters will be impacted by 2023?
— What will be the average age of the impacted helicopters by 2023?
— What will be the cost of implementing:
• retrofit?
• fleet change?
• multi-pilot operations?

4. Impact assessment (IA)
4.4. Delegation of maintenance tasks to the technical crew member
4.4.1. The issue to be addressed
Part-145 maintenance organisations are required to use appropriate aircraft-rated certifying staff,
qualified as Category B1, B2 or B3 under Part-66. For the line maintenance of an aircraft that operates
away from a supported location, the maintenance organisation may derogate from the rules and issue
a limited certification authorisation to the commander, who will be in charge of small maintenance
tasks without holding a Part-66 licence. The issue is whether to extend this derogation to the technical
crew member for the maintenance of the hoist.
4.4.2. Who is affected
NAAs, HEMS operators, maintenance organisations, maintenance personnel, HEMS pilots, and
technical crew members.
4.4.3. How could the issue/problem evolve
Unless they are amended, the rules will remain prescriptive and will require either the commander or a
licensed engineer to be in charge of the hoist maintenance.
4.4.4. What do we want to achieve
To make the rules more performance-based, and allow the technical crew member in charge of
operating the hoist to be trained to the same proficiency level as the pilot and be allowed to be in
charge of limited hoist maintenance.
4.4.5. How it could be achieved — options
The following options have been analysed:
Option No Description
0 No policy change.
5 Extent the issue of a limited certification authorisation to the HEMS crew member in the
case of aircraft that operate away from a supported location.
4.4.6. Delegation of maintenance tasks — analysis of impacts
4.4.6.1 Delegation of maintenance tasks — safety impact
Option 0: No impacts expected.
Option 5: There have been cases of damage to the cable not being detected by commanders during
the ‘daily after the last flight’ cable inspection. Luckily, they were detected during regular maintenance
performed by Part-66 licensed personnel.
Technical crew members do not have to have an aviation background or hold a licence. If they are in
charge of hoist maintenance, the risk of damage going undetected and thus resulting in lack of
maintenance will increase. Safety will be affected.
4.4.6.2 Delegation of maintenance tasks — social impact
Option 0: No impacts expected.

4. Impact assessment (IA)
Option 5: A low positive impact is expected due to reduced pilot workload and increased technical
crew member experience.
4.4.6.3 Delegation of maintenance tasks — conclusion
The impacts can be summarised as follows:
Option 0 Option 5
No change
Safety impact 0 –2
Social impact 0 +1
TOTAL 0 –1
Conclusion: Option 5 is not supported.
4.5. Monitoring and evaluation
Monitoring is a continuous and systematic process of data collection and analysis about the
implementation/application of a rule/activity. It generates factual information for future possible
evaluations and impact assessments and helps to identify actual implementation problems.
With respect to this proposal, and according to what is included in the preferred option, EASA suggests
monitoring the following:
What to monitor How to monitor Who should monitor How often
Number and main Reports in ECR and EASA and national On a recurrent basis
causes of occurrences information collected authorities
(accidents/serious at MS level
incidents) related to
HEMS operations
Relevance of HEMS Number of MSs EASA and national On a recurrent basis
rules and regulations operating HEMS under authorities
national regulations,
extent of the variations
between HEMS and
national rules
Stakeholders are invited to provide:
— quantified justification of the possible impacts (e.g. economic, social, safety) of the options
proposed, or alternatively to propose a justified solution to the issue;
— any other information they may find necessary to bring to the attention of EASA; as a result, the
relevant parts of the RIA might be modified on a case-by-case basis.

5. Proposed actions to support implementation
— Implementation and standardisation efforts regarding the new requirements introduced in
Part-ARO
(Competent authorities, EASA)
— Providing supporting clarifications in electronic communication tools (SINAPSE or equivalent),
and creating a platform for Member States to exchange good practices on public interest sites
(PISs).
(Primarily targeted audience: competent authorities)
— Amending the current version of the frequently asked questions (FAQs) on the EASA website
regarding:
the applicability of the Air Operations Regulation to mountain rescue operations;
explanations on the carriage of cargo together with persons under HEMS HEC.
