Is it possible to fuel a jet using electrical power?

Fueling a jet using electrical power is plausible in certain scenarios, particularly in modern aircraft systems that incorporate advanced technologies. The correct answer highlights that as long as the power cord remains connected, it allows for the systems that manage fuel transfer to operate, which can include pumps and control systems necessary for the refueling process.

In actual practice, fueling typically involves manual operation and protocols that ensure safety and efficiency, but some contemporary systems may allow certain automated processes to operate when powered. However, it's essential to note that while electrical systems can aid in refueling, they cannot independently complete the entire process without human oversight and adherence to standard procedures.

Considering the other options, manual operation and the necessity of ground checks may limit the actions to human-triggered, which is not entirely reflective of the capabilities provided by modern technologies. Emergency refueling typically involves additional protocols and controls, which further separates it from the straightforward situation indicated by the correct answer—that power availability directly supports the fueling systems' functionalities.
