The airport traffic control tower (ATCT) is the facility which supervises, directs, and monitors the arrival and departure traffic at the airport and in the immediate airspace within 5 mi from the airport. The tower is responsible for issuing clearances to all departing aircraft, providing pilots with information on wind, temperature, barometric pressure, and operating conditions at the airport, and for the control of all aircraft on the ground except in the maneuvering area immediately adjacent to the aircraft parking positions called the ramp area.
