True or False: Fueling operators are allowed to leave the fueling unit unattended while connected to the aircraft.

Fueling operators are not permitted to leave the fueling unit unattended while it is connected to the aircraft because this practice poses significant safety risks. Unattended fueling operations can lead to accidents or emergencies that may go unchecked, increasing the risk of spills, fires, or unauthorized access to the aircraft. The protocols established for fueling operations prioritize safety by requiring that a trained operator remain present to monitor the process and respond immediately to any incidents or unusual occurrences. Adhering to this requirement ensures the safety of airport personnel, passengers, and the aircraft itself.
