Pilot-controlled lighting (PCL), also known as aircraft radio control of aerodrome lighting (ARCAL) or pilot-activated lighting (PAL), is a system that allows aircraft pilots to control the lighting of an airport or airfield's approach lights, runway edge lights, and taxiways via radio.
In many locations, smaller airports use pilot-controlled lighting systems when it is uneconomical or inconvenient to have automated systems or staff to turn on the taxiway and runway lights. In Canada, the lighting system is accessed through an aircraft radio control of aerodrome lighting (ARCAL) frequency, which is often shared with the CTAF.
The PAPI can be seen to the right (non-standard) side of the runway. The aircraft is slightly below the glideslope. A precision approach path indicator (PAPI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach.
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. [1] The majority of runway edge lights are clear or white, [2] but there are some exceptions to provide additional information to pilots in certain circumstances.
