In the event of an emergency deviation, what should a pilot do?

In an emergency deviation, it is critical for the pilot to notify Air Traffic Control (ATC) as soon as possible. This prompt communication is essential because it allows ATC to understand the situation and potentially provide assistance or modified instructions to help the pilot safely manage the emergency. By keeping ATC informed, the pilot ensures that they are aware of any changes in the situation, which also helps maintain safety for other aircraft in the area.

This immediate notification can involve stating "Mayday" or "Pan-Pan," depending on the severity of the situation, to convey the urgency of the matter. Quick communication enables ATC to effectively coordinate any necessary changes in traffic management — potentially clearing airspace or arranging for immediate landing opportunities. The sooner ATC is informed, the better positioned they are to provide the required support and ensure the safety of everyone involved.
