A heliport beacon should be provided at a heliport where:
a) long-range visual guidance is considered necessary and is not provided by other visual means; or
b) identification of the heliport is difficult due to surrounding lights
The heliport beacon shall be located on or adjacent to the heliport preferably at an elevated position and so that it does not dazzle a pilot at short range.
The heliport beacon emit repeated series of equispaced short duration white flashes.
The light from the beacon is show at all angels of azimuth.
This specification details Federal Aviation Administration requirements for airport light beacons at civil airports, military airports, seaplane bases, and heliports.
L-801H Medium intensity heliport beacon
L-802H High intensity heliport beacon
L-801H 33 to 39 flashes per minute (fpm)
L-802H 33 to 39 flashes per minute (fpm)
a. The duration of individual flashes must be from 75 to 300 milliseconds (ms).
b. The requirement above may be met in capacitor discharge-type beacons by a series of rapid successive flashes which appear to the viewer to be one uninterrupted flash.
a. Airport beacons must provide the following signal colors:
L-801H & L-802H Alternate white, green, and yellow
The airport beacons must be designed to operate from a standard line voltage below 600 volts, at a tolerance of ±10 percent, 60 Hertz line frequency, alternating current.
