Why is bonding and grounding essential during fueling?

Preventing static electricity buildup and discharge during fueling is what bonding and grounding aim to achieve. Fuel flow and movement of air can generate static charges, and a static spark in a fuel–air mixture can ignite vapors. Bonding creates a continuous conducting path between all components—aircraft, fueling hose, nozzle, and equipment—so they are at the same electrical potential, eliminating the voltage difference that could cause a spark. Grounding ties the fueling system to earth, draining away any accumulated charge rather than allowing it to jump to the aircraft or nozzle. Together, these practices minimize the ignition risk in the presence of flammable vapors, which is why they’re essential during fueling. They aren’t primarily about corrosion protection, speeding up fueling, or improving communication, which is why those options don’t fit the main purpose.
