What is a fundamental requirement from the flight plan regarding accuracy and completeness?

The accuracy and completeness of a flight plan are crucial for ensuring safety and effective communication with air traffic control and other pilots. Selecting the option regarding thorough briefing of each member of the formation flight reflects an understanding of a key safety protocol. Briefing each member ensures that everyone is aware of the flight's objectives, procedures, and any contingencies, thus promoting a coordinated and safe operation. This is particularly important during formation flying where close proximity to other aircraft requires all members to be on the same page regarding maneuvers and responsibilities.

The other options do not align with the principles of safety and thoroughness required in flight planning. Filing a flight plan without review can lead to oversights and potentially dangerous situations. Naming only the pilot as a mandatory requirement overlooks the need for complete information for effective flight management. Similarly, the ability to revise a flight plan after departure suggests a lack of preparedness and could compromise safety protocols established by aviation authorities. Prioritizing the accurate briefing of formation members bolsters operational integrity and aligns with best practices in aviation safety.
