Which system provides bonding during fueling/defueling?

• A. Grounding Rod
• B. Refueler / Defueler System
• C. Bonding Cable
• D. Static Ground

Answer: (B)

Bonding during fueling and defueling is about creating a continuous electrical path so aircraft, fueling equipment, and the ground are at the same electrical potential, preventing static discharge sparks in a flammable environment. The system that provides this bonding during fueling/defueling is the Refueler/Defueler System, which is designed to connect the aircraft’s fuel system to the fueling equipment and to a ground path with bonding conductors and clamps, maintaining electrical continuity as connections are made or broken. While a bonding cable is part of the process, the overall setup that ensures proper bonding during fueling is the refueler/defueler system. Grounding rods establish earth ground for structures in general, but they don’t provide the bonding path at the fueling interface. Static grounding is a broad practice to reduce static buildup, not the specific bonding arrangement used during fueling operations.
