What is a key function of radar in ATC?

Radar plays a crucial role in Air Traffic Control (ATC) by monitoring and guiding aircraft within controlled airspace. This involves detecting the position, speed, and direction of aircraft, which allows air traffic controllers to maintain safe distances between planes, facilitate efficient traffic flow, and manage the airspace effectively.

With radar, controllers can receive real-time data about air traffic, enabling them to communicate with pilots and provide necessary instructions for takeoffs, landings, and in-flight navigation. This function is vital for avoiding collisions and ensuring that flights adhere to their assigned routes and altitudes.

Other functions mentioned, such as tracking weather patterns or assisting in runway maintenance, do not directly relate to the primary role of radar in ATC. Similarly, calculating flight durations for scheduling is primarily conducted using flight management systems rather than relying on radar capabilities. Overall, the central purpose of radar in ATC is its ability to maintain situational awareness and control of aircraft within the airspace system.
