How should a controller respond to a pilot who declares an emergency?

When a pilot declares an emergency, the appropriate response for a controller is to acknowledge the emergency and provide assistance. This is critical because a declared emergency indicates that the pilot may be facing a dangerous or unstable situation that requires immediate attention and support from air traffic control.

By acknowledging the emergency, the controller is confirming that they have received the pilot's distress call, allowing them to respond appropriately and efficiently. This could involve providing necessary information such as directing the aircraft to the nearest airport, clearing airspace, or coordinating with emergency services to ensure the safest possible outcome.

In emergency situations, time is often of the essence, and proactive support from the controller can be vital in helping the pilot to stabilize the situation or safely manage the emergency. This approach aligns with standard operating procedures in aviation, which prioritize safety and effective communication during critical incidents.
