![]() Runways without approach lighting may provide radio controlled intensity adjustments of runway edge lights.On runways with both approach lighting and runway lighting (runway edge lights, taxiway lights, etc.) systems, the approach lighting system takes precedence for air-to-ground radio control over the runway lighting system which is set at a predetermined intensity step, based on expected visibility conditions.With FAA approved systems, various combinations of medium intensity approach lights, runway lights, taxiway lights, VASI and/or REIL may be activated by radio control.or DoD En-route supplement will list information on type, runway, and frequency used If flying an instrument approach, activating lights crossing the final approach fix provides enough time to spot the runway environment upon breaking out into landing.A good practice is to turn the lights on before entering the pattern, and refreshing them by keying the mic on each downwind leg.REMEMBER: after 15 minutes the lights turn off, do now allow this to happen while you are on a short final!. ![]() Controlled on one frequency, usually CTAF, but not always.All lighting systems which are radio controlled at an airport, whether on a single runway or multiple runways, operate on the same radio frequency.Control of lighting systems is often available at locations without specified hours for lighting and where there is no control tower or FSS or when the tower or FSS is closed (locations with a part-time tower or FSS) or specified hours.Radio control of lighting is available at selected airports to provide airborne control of lights by keying the aircraft's microphone. ![]()
