Air traffic controllers are professionals who help manage the safe movement of aircraft in the sky and on the ground. They work in control towers at airports and in area control centers, using radar and communication systems to guide pilots. Their main job is to ensure that planes take off, land, and fly safely without getting too close to each other. These controllers communicate with pilots, providing them with important information about weather conditions, flight paths, and any potential hazards. By coordinating the actions of multiple aircraft, air traffic controllers play a crucial role in keeping air travel safe and efficient for everyone involved, including passengers and airline staff.
