Spotlights are a part of supportive lighting. They are used when the lamps surrounding the landing zone do not provide sufficient light for a pilot to operate safely. They illuminate the TLOF, FTAO and/or the parking zone. They should be placed in such way that does not cause any threats for helicopters. Moreover, their light is directed down to illuminate the helipad surface and not to weaken a pilot’s visibility.
However, if the lights do hinder visibility in any way, a pilot should request turning the lights off. He or she may also be able to turn them off remotely by themselves. Landing direction indicator lights consist of five, green, multidirectional lights put at the center of a landing/takeoff line. They should be put in 5-meter intervals, and their line must be place more than 6 meters and less than 18 meters from the TLOF zone border.
