What should the pilot in command confirm regarding fuel levels before takeoff?

The pilot in command must confirm that fuel levels include reserves for all scenarios as part of their responsibility to ensure a safe flight. This means that in addition to the fuel required for the planned flight to the destination, the pilot must account for any potential diversions, holding patterns, and unexpected delays. Regulations often require a specific minimum reserve fuel quantity that must be on board at the time of takeoff, which ensures the aircraft can safely handle unforeseen circumstances. This comprehensive approach to fuel management is critical for flight safety and operational preparedness, aligning with standard aviation practices and regulations.

The other options do not sufficiently prioritize flight safety. Relying on minimal fuel levels under favorable conditions can lead to dangerous situations if those conditions change. Additionally, thinking that only enough fuel for a one-way flight is adequate ignores the unpredictable nature of flight and the need for contingency plans. Finally, dismissing the necessity to confirm fuel levels simply because refueling options are available does not alleviate the pilot's responsibility; plans can change, and ensuring sufficient fuel is always required for safety.
