Which of the following is a function of approach/tower radar services in aviation?

The function of approach/tower radar services in aviation is largely centered around determining the position of aircraft and providing separation between them. This is crucial for maintaining safe distances between aircraft in both the approach phase when they are descending toward the airport and upon landing, as well as during takeoff and initial climb phases.

Approach radar services assist in tracking the aircraft's location, speed, and altitude, enabling air traffic controllers to make informed decisions about sequencing arriving and departing flights safely. By determining the position of multiple aircraft in the airspace they manage, controllers can provide timely instructions to pilots to ensure safe operation within crowded airspace environments.

This role includes assessing potential conflicts between aircraft and implementing separation standards, which are vital to mitigating the risk of mid-air collisions and ensuring that pilots can safely navigate during critical phases of flight.
