What should a pilot do when encountering a distress condition during IFR flight?

When a pilot encounters a distress condition during IFR flight, declaring an emergency and obtaining an amended clearance is the correct response. This action provides immediate notification to air traffic control (ATC) about the seriousness of the situation. By declaring an emergency, the pilot secures priority handling from ATC, which is crucial when navigating potential challenges or hazards. An amended clearance allows the pilot to adjust their route or altitude as necessary to resolve the situation safely, ensuring that they are adequately supported by air traffic services during the emergency.

Additionally, prioritizing communication with ATC in emergencies helps facilitate effective coordination for assistance or runway access, potentially smoothing the path to a safe landing. This proactive approach aligns with the established procedures for handling in-flight emergencies under IFR, emphasizing safety and the importance of clear communication.

The other options do not adequately address the severity of a distress condition and might lead to miscommunication or a failure to receive appropriate assistance in a timely manner.
