When should ATC grant priority to distressed aircraft?

Priority should be granted to distressed aircraft whenever distress is indicated because safety is the primary concern in aviation operations. Distressed aircraft, which may be experiencing technical failures, fuel shortages, medical emergencies, or other serious situations, require immediate assistance to ensure the safety of those on board and on the ground.

Prioritizing such aircraft can facilitate faster routing, clearance, and communication to help resolve the situation as effectively as possible. It is crucial for air traffic control (ATC) to respond to any indications of distress proactively, regardless of the current traffic conditions. This approach ensures that the necessary resources and attention are swiftly directed to the aircraft in need, which is vital for preserving lives and managing emergencies effectively.

Granting priority only during emergencies declared by the pilot, only when there is no other air traffic, or solely during off-peak hours would unnecessarily complicate response efforts and could potentially lead to a dangerous situation where timely assistance is not provided.
