How many cabin crew members are required onboard when fueling during embarkation/disembarkation with passengers present?

The requirement for the number of cabin crew members during the fueling process when passengers are on board is dictated by the need for safety and regulatory compliance. Having four cabin crew members present ensures that there are enough personnel to effectively monitor the situation, assist passengers, and respond quickly in case of an emergency.

During fueling, it is crucial to have a designated crew member outside the aircraft to relay any potential hazards and to communicate with the fueling team. The additional crew members can ensure that all passenger needs are accounted for and can assist with any necessary emergency procedures. This additional presence of cabin crew guarantees a safer environment while maintaining effective oversight of the boarding and disembarkation process.

Having fewer than four crew members would compromise the level of safety management and emergency response capability, which is why four is the correct number in this context.
