When following lost communications procedures, what is the first altitude to consider?

The appropriate first altitude to consider when following lost communications procedures is the minimum altitude prescribed for Instrument Flight Rules (IFR). This altitude is crucial as it ensures a safe flying environment above terrain and obstacles, providing the pilot with the necessary margin for safety in the event of communication loss.

In the case of lost communications, the pilot must prioritize maintaining a safe flight path. The minimum altitude for IFR operations is established to prevent altitude conflicts with other air traffic and obstacles, allowing the pilot to remain within legal and safety parameters until further instructions can be established or the situation is resolved.

The last altitude assigned by Air Traffic Control (ATC) may be relevant; however, it does not account for potential safety risks associated with the airspace. Similarly, considering an assigned altitude only does not provide any assurance regarding obstacle clearance. Lastly, selecting any altitude below 5,000 feet disregards specific safety protocols and regulations that are in place to protect both the aircraft and its occupants.

By focusing on the minimum altitude for IFR operations first, pilots can effectively ensure they remain at a safe height, are compliant with regulations, and can avoid risks associated with altitude during periods of lost communication.
