Is it permissible to fuel a jet with external power on?

Fueling a jet while using external power is permissible because external power does not typically interfere with the fueling process, and safety procedures are in place to manage any associated risks. When fueling an aircraft, especially a jet like the Super Hornet, careful adherence to standard operating procedures ensures that any potential hazards are mitigated.

It is critical to note that pilots and crew must be aware of grounding procedures to avoid static discharge during fueling operations, which can ignite fuel vapors. Maintaining proper communication and awareness of the aircraft's systems while connected to external power is essential.

This practice streamlines operations and optimizes readiness, as there is a need to have systems operational while the aircraft receives fuel. Overall, while proper precautions should be taken, having external power on during fueling is an accepted procedure in certain scenarios, aligning with operational efficiency.
