What should be done to protect aircraft surfaces during refueling?

Protecting aircraft surfaces during refueling is critical to maintaining the integrity and appearance of the aircraft. The correct action is to protect surfaces from hose and nozzle damage. This involves taking the necessary precautions to prevent contact between fueling equipment and the aircraft's surfaces, which can lead to abrasions, scratches, or other forms of damage. Careful handling of, and maintaining distance from, the refueling hose and nozzle can minimize the risk of accidental contact with the aircraft.

While using specific materials like stainless steel hoses or applying wax may be beneficial for other reasons, they are not directly related to the immediate protection of surfaces during the refueling process. Additionally, while ensuring that personnel are safe is important, the focus here is specifically on the aircraft surfaces themselves. Properly managing equipment during refueling is the most effective way to keep the aircraft protected.
