How long does it take to defuel the T-6A through the over the wing gravity refueling ports?

The T-6A cannot be defueled through the over the wing gravity refueling ports because these ports are specifically designed for refueling only, not for defueling. In normal operation, the aircraft is equipped with a fuel system that allows defueling through dedicated defueling ports located on the aircraft’s fuselage. Defueling through the gravity refueling ports would be impractical and could lead to fuel system complications, spills, or other issues, which is why these ports are not used for that purpose. Understanding the design and function of the T-6A's fueling system is crucial for safe and efficient aircraft operation.
