What procedures should be followed in a lost communications scenario?

In the event of a lost communications scenario, following the chronological order of assigned, vectored, expected, and filed is the correct procedure. This method is designed to prioritize the most recent and relevant information available to the pilot for maintaining safe operations.

The sequence begins with any instructions given by Air Traffic Control that were assigned to the pilot. If those instructions are not available, the pilot should then consider any vectors provided during the flight. If neither of those is applicable, the next step would be to refer to expected instructions that the pilot is anticipating from ATC, and finally, if no communication has been established for a considerable time, the pilot should rely on the filed flight plan.

This structured approach ensures that the pilot acts methodically and remains as close as possible to the intended route of flight while maximizing the chances of reestablishing communication with ATC. It also allows for the safe avoidance of potential airspace conflicts and helps maintain situational awareness.

The other choices would not systematically provide the best path forward. For example, flying at MEA altitude only does not take into account the most current directives that may assist in determining safety and navigation. Immediately turning around could lead the pilot into airspace or situations that are not safe without adequate information on
