An Air Traffic Controller (ATC) is a professional responsible for ensuring the safe and efficient movement of aircraft in the sky and on the ground. They communicate with pilots using radios, providing instructions on takeoffs, landings, and flight paths. By managing the flow of air traffic, ATCs help prevent collisions and delays, making air travel safer for everyone. To perform their job, Air Traffic Controllers use radar and other technology to track aircraft positions. They work in control towers at airports or in area control centers, often under high pressure. Their role is crucial in maintaining the organization and safety of the busy skies.
