What must be done before conducting Aircraft refueling operations?

Before conducting aircraft refueling operations, it is crucial that the aircraft is properly bonded to the refueling equipment. Bonding ensures that any static electric charge that may be present is equalized between the aircraft and the fueling equipment, which significantly reduces the risk of sparks that could ignite fuel vapors. This is an important safety measure in aviation operations, as fueling involves highly flammable materials.

Establishing a proper bond is a standard protocol that helps to mitigate the hazards associated with refueling, ensuring that both the aircraft and the equipment are at the same electrical potential. By doing so, it helps to protect the safety of ground crew and equipment involved in the operation.
