What is the main function of air traffic control?

The main function of air traffic control is to coordinate aircraft movements on the ground and in the airspace. This involves directing aircraft during takeoff and landing, providing guidance during flights, and ensuring safe distances between aircraft to prevent collisions. Air traffic controllers use radar, visual observation, and communication with pilots to manage the flow of air traffic efficiently and safely.

Effective air traffic control preserves the organization within busy airspaces, which is crucial for maintaining safety in the aviation industry. The role encompasses not only the immediate control around airports but also the broader management of air routes, ensuring that flying is as safe and orderly as possible. Unlike the other options, which either do not relate directly to air traffic control or focus on unrelated areas within aviation, the core mission revolves around the real-time coordination and safety of aircraft movements.
