Heliport lighting normally consists of a circle or square of inset lights around the surface called the TLOF (touchdown and lift-off area) and another around the overall [[landing]] area called the [[FATO]] (final approach and takeoff area). The later encompasses the TLOF as well and the lights may be elevated or inset. Both sets of lights are now recommended to be green by the [[International Civil Aviation Organization]] and [[Federal Aviation Administration]]. Yellow (amber) was the former standard and is still preferred in many locations. There is a great deal of variance in color depending on the owner and jurisdiction. These lights were traditionally [[incandescent]] but are now increasingly [[light-emitting diode]]s with brightness control. The TLOF and FATO lights may be supplemented with surface [[flood light]]s. A lighted [[wind cone]] is necessary. At ground-based locations, a row of [[lead-in lights]] in the preferred direction of approach is sometimes used. Visual slope [[guidance system]]s (such as HAPI, PAPI, etc) are recommended in both ICAO and FAA documents but are rarely deployed due to the high cost relative to the rest of the lighting system. While airports commonly use 6.6A [[direct current]] power, heliport lighting is normally [[AC power]]ed. [[Radio control]] by the pilot via a automated ground-based controller is also common.{{factFact|date=May 2008}}
