What role does "air traffic control" play in aviation?

Air traffic control plays a vital role in aviation primarily by managing aircraft movements within controlled airspace. This involves providing instructions to pilots regarding navigation, altitude, and flight path to ensure safe and efficient operations. By overseeing the traffic and coordinating between different aircraft, air traffic controllers help prevent collisions, thus maintaining safety in busy airspaces. They also facilitate the orderly flow of air traffic, allowing for safe takeoffs, landings, and transitions through various airspace sectors. The effectiveness of air traffic control is crucial, especially in congested areas where multiple aircraft are operating near each other, as it greatly reduces the risk of accidents.
