Airport Engineering: What is the TLOF Lighting System?

What is a TLOF lighting system? The airport project will tell you today that for nighttime heliports.a TLOF lighting system should be set up，However, when the track-type FATO coincides with the TLOF. it may not be set. The surface TLOF lighting system of the heliport is mainly illuminated by sidelights, floodlights. spaced point light arrays (ASPSL) or light-emitting panel (LP) lighting (when it is difficult to set up edge or floodlights with FATO lamps) A variety of lighting systems or several components' TLOF lighting systems for elevated heliports or helicopter platforms should include: edge lights, floodlights, and/or spaced point light arrays (ASPSL) and/or light-emitting-plate (LP) lighting.

For surface heliports for night use, TLOF floodlighting or spaced spotlight array lighting or luminescent panel lighting should be provided for enhanced surface signatures.
