Term: Airport Traffic Control Tower
Definition:
Airport Traffic Control (ATC) towers are terminal facilities that use air and ground communications, visual signalling and other devices to provide ATC services to aircraft operating in the vicinity of an airport or on the movement area. They authorise aircraft to land or takeoff at the airport or to transit the class D airspace area regardless of flight plan or weather conditions (IFR or VFR). A tower may also provide approach control services (radar or non-radar).
