Can you change the electrical condition of the plane while fueling?

• A. No
• B. Yes, with approval
• C. Yes, only during ground power on
• D. Only if safety dictates

Answer: (A)

During fueling, electricity can be an ignition source. Any change to the aircraft’s electrical condition—like turning systems on or off or energizing equipment—can create a spark or arc that could ignite fuel vapors. To minimize that risk, the electrical state is kept in a safe, constant condition throughout the fueling process. That’s why the correct approach is not to change the electrical condition while fueling.
