approach lights

Layout of a simple airfield approach lighting system.A system of high-intensity lights located along the approach path of an instrument runway. The lights radiate beams in a directional pattern by which a pilot aligns the aircraft with the extended centerline of the runway on the final approach for landing. They assist the pilot in transitioning from instrument flight conditions to visual conditions at the end of an instrument approach. These lights extend into the approach area up to a distance of 2400 to 3000 ft (730–900 m) for the precision instrument runway and 1400 to 1500 ft (420–450 m) for the non-precision runway.
