What is one application of RADAR in aviation?

Tracking aircraft movements is a significant application of RADAR in aviation. RADAR systems are employed to monitor the positions and trajectories of aircraft in real-time, which is essential for safe flight operations. This capability allows air traffic control to manage the spacing between aircraft, prevent collisions, and ensure orderly landings and takeoffs. The detailed information provided by RADAR about an aircraft’s speed, altitude, and direction enhances situational awareness for both pilots and air traffic controllers, which is critical in crowded airspaces.

Other applications mentioned, such as measuring soil moisture levels and calculating fuel efficiency, do not relate to aviation and utilize different technologies. While providing real-time weather updates is an important function in aviation, it typically involves different systems, such as METAR and TAF reports, rather than primarily relying on RADAR systems designed for tracking aircraft.
