In the aerospace context, ATC stands for Air Traffic Control. It is a service provided by ground-based controllers who direct aircraft on the ground and through controlled airspace, and can provide advisory services to aircraft in non-controlled airspace.
The primary purpose of ATC is to separate aircraft and to provide a safe, orderly, and efficient flow of air traffic. ATC is a service that is provided by government agencies, such as the Federal Aviation Administration (FAA) in the United States, and the Civil Aviation Authority (CAA) in other countries.
Examples of ATC services include:
- Tower control: This service is provided at airports and it involves controlling the movement of aircraft on the ground and in the airspace immediately surrounding the airport.
- Approach control: This service is provided at airports and it involves controlling the movement of aircraft on final approach to the airport.
- En route control: This service is provided at air traffic control centers and it involves controlling the movement of aircraft between airports.
- Flight service station: This service provides flight planning, weather briefings, and other services to pilots in non-controlled airspace.
ATC services are critical for the safe and efficient operation of the aerospace industry. Air traffic controllers use a variety of tools, such as radar, communication systems, and weather information, to track and direct aircraft, and to provide pilots with information and guidance to ensure safe and efficient flight. The ATC system is constantly evolving to keep up with the increasing demand for air travel, and to take advantage of new technologies to make the system safe.
