What action should an aircraft take when radar contact is terminated?

When radar contact is terminated, an aircraft should resume normal non-radar position reporting. This is important because once radar service is lost, the air traffic controller can no longer monitor the aircraft's position and altitude directly. The aircraft is required to revert to the procedural communication methods that are standard in non-radar airspace.

In non-radar environments, pilots provide position reports based on specific intervals or when passing designated reporting points. This ensures air traffic control has the necessary information to maintain safe separation between aircraft, even without radar tracking.

By returning to normal position reporting, the pilot aids in maintaining situational awareness for both themselves and air traffic control, which is crucial for the safety of all aircraft in the vicinity.
