How can static accumulation associated with aircraft fueling operations be minimized?

Grounding the airplane and the fueler during aircraft fueling operations is essential to minimize static electricity accumulation. When fuel is transferred, the movement of fuel can generate static electricity due to friction and turbulence. This static charge can accumulate on both the aircraft and the fuel delivery system.

By effectively grounding both the airplane and the fueling equipment, any static electricity that builds up can be safely dissipated to the ground. This process reduces the risk of ignition of flammable vapors that could be generated during fueling operations. Grounding ensures that the charge does not reach a sufficient level to cause a spark, which could ignite any fuel vapors present.

In contrast, using non-conductive materials or avoiding bonding would not help in preventing static buildup, as these methods do not allow for the dissipation of electric charge. Additionally, failing to ground the airplane and the fueler may create dangerous situations where static buildup could lead to an explosion or fire during the fueling process. Hence, ensuring proper grounding is a critical safety measure in these operations.
