Air Traffic Control (ATC) is a service that manages the movement of aircraft in the sky and on the ground. Its primary goal is to ensure the safety and efficiency of air travel by coordinating takeoffs, landings, and in-flight navigation. ATC personnel use radar and communication systems to monitor aircraft positions and provide instructions to pilots. ATC operates in various sectors, including en-route control, which manages aircraft flying at high altitudes, and tower control, which oversees aircraft at airports. This system is essential for preventing collisions and maintaining orderly air traffic flow, contributing to the overall safety of the aviation industry.
