What is the role of bonding in reducing static charges on the airframe?

• A. It isolates static charges from the airframe
• B. It provides a continuous, low-impedance path to equalize potentials and dissipate static
• C. It stores energy for emergency use
• D. It converts AC to DC

Answer: (B)

Bonding keeps all metal parts of the airframe at the same electrical potential by providing a continuous, low-impedance conductive path between components and to the grounding system. When static charges build up, this path lets charges flow and equalize across surfaces rather than accumulating at isolated spots, so the charge is safely dissipated to ground. This reduces the chance of disruptive sparks and interference with avionics during fueling and operations. It’s not about isolating charges, storing energy, or converting AC to DC, which is why the other options don’t fit.
