Under company procedures, when may passengers remain onboard during single-point fueling?

• A. You must always remove all passengers
• B. Only if the main cabin door is closed
• C. Never allowed
• D. Provided at least one crewmember onboard to monitor

Answer: (D)

During single-point fueling, there are hazards such as fuel spills, fumes, and static that require supervision by trained crew. If passengers are onboard, the operation is permitted only when at least one crewmember is onboard to monitor. This provides a person who can watch for any abnormal conditions, ensure cabin safety procedures are followed, and coordinate with the fueling team if anything needs attention. The other options are too absolute or miss the key control: you don’t automatically remove all passengers, the status of the main cabin door isn’t the deciding factor, and you don’t categorically prohibit fueling with passengers onboard when a crewmember is present to monitor.
