What should be briefed in anticipation of non-local sorties in relation to lost communications?

Anticipating non-local sorties involves ensuring that all crew members are aware of procedures that help maintain safety in the event of lost communications. Briefing a flight plan that adheres to the Flight Information Handbook is crucial because this document contains important information about expected routes, altitudes, communication frequencies, and other pertinent operational details. Understanding the flight plan enables crew members to have a clear understanding of the intended operation, which is vital during unexpected situations like communication failures.

By adhering to established guidelines within the Flight Information Handbook, the crew can better navigate through potential emergencies. While the other options may contain useful procedures, they are not as comprehensive as the flight plan in helping the crew maintain situational awareness and navigate when communication is lost. Being well-versed in the flight plan boosts the team's preparedness for maintaining safe operations and executing the necessary actions to ensure the safety of the sortie despite challenges.
