Definition#
ATC stands for Air Traffic Control. It is the ground-based service responsible for directing aircraft movement on the ground and through controlled airspace, maintaining safe separation between aircraft, and providing advisory services.
Why It Matters Operationally#
ATC manages takeoff and landing sequences, en-route separation, and weather-related reroutes. Controllers use radar, communication, and procedural standards to ensure orderly traffic flow. Airport throughput, delays, and safety are all directly tied to ATC capacity and performance.
Common Misunderstandings#
- ATC does not control aircraft in uncontrolled (Class G) airspace.
- Pilots flying VFR in Class E airspace above 1,200 ft AGL are not required to communicate with ATC unless entering Class B, C, or D airspace.
