Where should entry and exit times be documented on the flight plan?

Documenting entry and exit times in the flight plan is crucial for tracking the timeline of the flight's operations. The correct option, which specifies this information is housed in the Remarks, group one section, allows for clear and organized annotation of critical flight information that is readily accessible to all relevant team members. This ensures that details such as when the aircraft enters and exits various airspaces or controlled zones are properly recorded, which is essential for compliance with air traffic regulations and effective communication among crew members.

The Remarks section is specifically designed for unique or additional information that doesn't fit into the structured sections of the flight plan. It serves as a catch-all for information that is important for the mission's success and safety, including nuanced details about timings that support operational transparency and adherence to protocols during the flight.
