Terminal Radar Approach Control (TRACON) is a facility that manages aircraft arriving and departing from airports within a specific airspace. It uses radar technology to track and guide planes during their approach and departure phases, ensuring safe distances between aircraft. TRACON controllers communicate with pilots to provide instructions on altitude, speed, and flight paths. This coordination helps prevent collisions and optimizes the flow of air traffic, especially in busy airport environments. By managing the airspace efficiently, TRACON plays a crucial role in maintaining safety and order in aviation.
