What is the priority of an air traffic controller during a PANPAN call?

The priority of an air traffic controller during a PANPAN call is to respond immediately and provide necessary assistance. A PANPAN call indicates a situation that is urgent but not life-threatening, signaling that the aircraft may require help but not necessarily immediate emergency services. The controller's primary role is to ensure the safety and well-being of the aircraft, its crew, and passengers, as well as the airspace around them.

By responding promptly, the controller can assess the situation, gather information from the pilot, and coordinate any required support or traffic management. Immediate assistance during a PANPAN call helps to mitigate risks and ensure that the situation is managed effectively, maintaining safety and order in the airspace.
