Why is it considered good operating procedure to file the fuel tanks after the last flight of the day?

To prevent overfilling the tanks
To reduce the weight for the next flight
To prevent moisture condensation by eliminating airspace in the tanks
To enhance engine performance for the next flight

The correct answer is: To prevent moisture condensation by eliminating airspace in the tanks

Filing the fuel tanks after the last flight of the day is beneficial primarily to prevent moisture condensation by minimizing the airspace in the tanks. When fuel tanks contain air, temperature changes can cause condensation to form inside the tank, leading to water accumulation. Water is detrimental to engine operation, as it can cause corrosion, decrease fuel quality, and potentially lead to engine failure. By filling the tanks to the top, you eliminate the airspace, thus reducing the potential for condensation and effectively protecting the fuel system from moisture-related issues. Additionally, keeping the tanks full also helps in managing the overall health of the aircraft, as it reduces the risk of fuel contamination and helps ensure a stable fuel supply for the next flight.
