• ED Decision 2019/012/R found in: Aerodromes (139/2014) Part-ADR.AR Part-ADR.OR Part-ADR.OPS CS-ADR-DSN CS-HPT-DSN (Jun 2023)

CS HPT-DSN.F.670 Final approach and take-off area lighting systems ED Decision 2019/012/R (a) Applicability: FATO lights should be provided where a FATO is established at a heliport intended for use at night. They can be omitted where the FATO and the TLOF are nearly coincidental and the TLOF lights are provided, or the extent of the FATO is self-evident. (b) Location: FATO lights should be placed along the edges of the FATO. The lights should be uniformly spaced as follows: (1) for an area in the form of a square or rectangle, at intervals of not more than 50 m with a minimum of four lights on each side including a light at each corner; and (2) for any other shaped area, including a circular area, at intervals of not more than 5 m with a minimum of ten lights. (c) Characteristics: (1) FATO lights should be fixed omnidirectional lights showing white. Where the intensity of the lights is to be varied, the lights should show variable white. (2) The light distribution of FATO lights should be as shown in Figure F-9, Illustration 4. (3) The lights should not exceed a height of 25 cm and should be inset when a light extending above the surface would endanger helicopter operations. (4) Where a FATO is not meant for lift-off or touchdown, the lights should not exceed a height of 25 cm above ground or snow level.
