The following are examples of types of air traffic controllers: TOWER CONTROLLERS direct the movement of vehicles on runways and taxiways. They check flight plans and give pilots clearance for takeoff and landing. Most work from control towers, watching the traffic they control. APPROACH CONTROLLERS take over responsibility for the aircraft from the area control/tower control. They ensure that aircraft traveling within an airport’s airspace maintain minimum separation. They give clearances to enter controlled airspace and hand over control of aircraft to en route or tower controllers. They also provide information to pilots, such as weather conditions and other critical notices. ENROUTE CONTROLLERS monitor aircraft in the upper airspace. They work at area control centers located throughout the country, typically not at airports.
