FATO and TLOF Lights
A minimum of four flush or raised light fixtures is recommended per side of a rectangular FATO or TLOF. A light is located at each corner with additional lights uniformly spaced between the corner lights with a maximum interval of 25 feet (7.5 m) between lights. Lamps are 40 watt, 120 volt or 45 watt, 6.6 ampere bulbs.
Lighted Wind Indicator
An FAA L807 Size 1 (about 22 ft overall height with an 8 ft, international orange windsock) is recom-mended, or the L806 (10 ft tall) may be substituted. The L807 has a hinged pole and a rigid base, the L806 has a frangible base. Both use four 120 watt, 120 volt PAR38 lamps to illuminate the windsock and a 116 watt lamp for the obstruction light. The L807 must be outside the safety zone and away from flight paths.
Heliport Identification Beacon
Located within 1/4 mi of the heliport, three 500 watt sealed beam lights rotate at 10 to 15 rpm to produce 30 to 45 fpm in white, green and yellow. Not required on lighted airports. Flash Technology beacon using Morse code signals is also available.
Landing Direction Lights
To identify alignment of the approach route, a line of five L860 or L861 lights with omnidirectional yellow lenses are spaced at 15 ft (4.5 m) intervals.
Floodlights
Mounted on buildings or poles, elevated floodlights should illuminate all of the operational area and should be hooded to prevent upward glare that would hinder the vision of approaching pilots.
Taxiway Lights
Taxiway center lines are defined with semi-flush L852A and L852B bi-directional or unidirectional green lights spaced at 50 feet (15 m) intervals. Blue lights set at the same intervals are used to define the edges of an unpaved taxi route.
Obstruction Lights
Objects exceeding a height of 200 feet (61 m) above the ground and within one nautical mile of the airport shall be marked with a red FAA approved obstruction light. Review Flight Light’s Obstruction Light Brochure for requirements. Contact the local FAA office with additional questions.
Visual Glide Path Indicator
The heliport approach path indicator (CHAPI) provides pilots with visual course and descent cues. The optimum location of a CHAPI is on the extended center line of the approach path at a distance that brings the helicopter to a hover 3 to 8 feet (0.9 to 2.5 m) above the TLOF center.
