Which of the following statements is true regarding the bond between the fuel supply and the aircraft?

The statement regarding the bond between the fuel supply and the aircraft that is accurate states that it prevents static electricity buildup. This is a crucial aspect of aviation safety. When fuel is transferred or moved within the aircraft, particularly in conditions where fuel moves rapidly (such as during refueling), it can generate static electricity. If this static charge accumulates to a sufficient level, it can create a spark that may ignite flammable vapors in the fuel system or during the fueling process. Establishing a proper bond—by connecting a grounding cable between the fuel source and the aircraft—allows any static charge to safely dissipate to the ground, thereby mitigating the risk of a fire or explosion.

The other statements do not accurately reflect the relationship between the fuel supply and the aircraft. The bond is not specific to humid conditions, as static electricity can occur in a variety of environments. While stabilization of the aircraft during flight can be influenced by fuel load and distribution, this does not pertain to the bonding process itself. The statement regarding electric pumps suggests that bonding is unnecessary if such pumps are used, which is incorrect, since static electricity concerns persist regardless of the type of fuel delivery system in use. Thus, understanding the importance of grounding and bonding in aviation fuel systems is
