Question: 1 / 550

What information does Airport Surveillance Radar (ASR) provide to air traffic controllers?

Location and altitude of airplanes

Only the altitude of airplanes

Only the location of airplanes

The correct choice highlights that Airport Surveillance Radar (ASR) primarily provides the location of airplanes. ASR is designed primarily for use in terminal airspace to assist controllers in tracking aircraft. It uses a process called radar reflection to determine the position of aircraft in the airspace around an airport.

While ASR does not provide altitude information directly, it is crucial for controllers to manage aircraft during takeoff, landing, and while in the traffic pattern. Controllers can derive altitude data from other sources, such as transponder information or secondary radar systems.

ASR does offer some basic information regarding the speed and direction of the aircraft based on their movement between radar sweeps, but this is not its main function. Overall, the functionality of ASR is centered on providing an accurate picture of aircraft locations, ensuring safe and efficient traffic management around airports.
