![]() They look white to the pilot approaching from the short end of the runway, but to a pilot approaching from the other end, who would be landing or taking off in that direction, they are yellow to indicate that the runway is nearing the end. Found in AIXMv.5.1.1.AIXM.AIXM package.AIXMv.5.1.1.AIXM.AIXM Features. How does the system work if there’s no one to listen on the other end of the radio The pilot triggers the lights by keying the aircraft’s microphone when tuned in to the frequency. You might also find it referred to as the Aircraft Radio Control of Aerodrome Lighting or ARCAL. ![]() When an instrument runway lighting is designed, the last 600 metres (2,000 ft), or one-half of the runway length available (whichever is less), are bi-directional. Diagram - Lighting / Pilot Controlled Lighting. It’s called the PCL, or Pilot Controlled LIghting system. The majority of runway edge lights are clear or white, but there are some exceptions to provide additional information to pilots in certain circumstances. The integration of VHF with SMS enables both remote pilot or operator control via radio, whilst enabling the system to be controlled and monitored from any position globally via a text message on SMS. These airports will have Pilot Controlled Lighting, or PCL, where pilots can adjust the lighting themselves by keying a microphone button a certain number of times. FEC Remote Lighting Controller represents the combination of two wireless technologies. ![]() At airports where there is a control tower, the tower will manage the lights to account for visibility and pilot preference, but some airports do not have control towers. After a preset time (usually 5 to 15 minutes), the ob and windsock lights would automatically shut down. Many HIRL and MIRL systems have variable intensity controls, whereas the LIRLs normally have one intensity setting. While reviewing a recent approach and landing aid lighting issue, NBAA observed that the approach, runway, and airport lighting information is scattered throughout the sub-sections of an individual airport’s entry in the FAA Chart Supplement. These light systems are classified according to the intensity they are capable of producing: Runway edge lighting are used to outline the edges of runways during periods of darkness or restricted visibility conditions. ![]() An aircraft landing at Zurich International Airport, with runway edge lights visible For the airport with ICAO code LIRL, see Latina Air Base. ![]()
