The PHL elevated LED lights mark the perimeter (FATO) of a heliport. The FAA recommended perimeter color is green. The ICAO recommended color is green (C-array) when the FATO and TLOF are the same or white (H-array) when there is a separate green TLOF inner perimeter. The purpose of the PHL’s LED floodlight is to provide light “washing” the pad surface to provide better depth perception to the pilot than simply having perimeter lights. It improves conspicuity to the pilot but does not provide uniform, illumination of the pad surface. The floodlight is engineered to be well controlled and reduce glare to the pilot. The overall height is compatible with standard height PEL’s to be used together on the same perimeter. The LED floodlight should be separately circuited for control independent of the colored LED perimeter light.
