What is the minimum fuel required for safe flight operation?

The minimum fuel required for safe flight operation in the T-6A is 200 pounds in each wing tank. This requirement ensures that the aircraft has enough fuel for safe operation, considering factors such as fuel consumption rates, reserve fuel needs, and the potential for fuel imbalance. Maintaining at least this amount in each wing tank helps to prevent engine fuel starvation during critical phases of flight, particularly in case of unexpected fuel consumption or emergencies. Having sufficient fuel in each tank also contributes to maintaining the aircraft's center of gravity and overall flight stability.

The other choices may not provide adequate fuel reserves for safe operations, potentially compromising the aircraft's performance and safety during flight.
