Therefore, the number of lights needed to meet this requirement will depend on the horizontal beam spreads of each light as well as the shape of the obstacle. Thus, with narrower beam spreads, more lights will be required. a) 360° horizontal. For flashing lights, the intensity is read into effective intensity, as determined in accordance with the Aerodrome Design Manual (Doc 9157), Part 4. b) Between 2 and 10° vertical. Elevation vertical angles are referenced to the horizontal when the light is levelled. c) Between 2 and 20° vertical. Elevation vertical angles are referenced to the horizontal when the light is levelled. d) Peak intensity should be located at approximately 2.5° vertical. e) Peak intensity should be located at approximately 17° vertical. f) Beam spread is defined as the angle between the horizontal plane and the directions for which the intensity exceeds that mentioned in the “intensity” column.

For flashing lights, the intensity is read into effective intensity, as determined in accordance with the Aerodrome Design Manual (Doc 9157), Part 4. b) Elevation vertical angles are referenced to the horizontal when the light unit is levelled. c) Beam spread is defined as the angle between the horizontal plane and the directions for which the intensity exceeds that mentioned in the “intensity” column. Note.— An extended beam spread may be necessary under specific configuration and justified by an aeronautical study. 6-5 14/11/13 Tere! Kuna hoone läbib Tallinna lennuvälja lähiümbruse sisemist horisontaalpiirangupinda, tuleb selle nurkadesse paigaldada madalintensiivsusega tüüp B (low-intensity type B) lennuohutustuled.
