What is required of crew members when fueling operations occur with passengers on board?

• A. At least one crew member must remain on board
• B. All crew members must evacuate
• C. No crew members are allowed on board
• D. Only the captain must remain

Answer: (A)

In situations where fueling operations are conducted with passengers aboard an aircraft, it is essential that at least one crew member remains on board. This is primarily to ensure the safety and well-being of passengers in case of an emergency or any unforeseen incidents that may arise during the fueling process. Having a crew member present allows for immediate communication with ground personnel and readiness to provide instructions or assistance to passengers.

Furthermore, regulations and safety protocols typically require that the aircraft is monitored during fueling operations to manage any potential hazards effectively. While it may seem reasonable to consider evacuating all crew members or only allowing the captain to remain, these approaches would limit the aircraft's immediate response capabilities should the need arise. Thus, maintaining a presence of at least one crew member on board strikes a balance between safety compliance and readiness to act in case of an emergency.
