What additional requirement is in place for an A321 with passengers onboard?

For an A321 with passengers onboard, the regulation stipulates that there must be at least two flight attendants present. This requirement is in place to ensure that there is sufficient crew to manage the safety and welfare of passengers during flight, particularly in the event of an emergency. The presence of multiple flight attendants helps to ensure that there are enough personnel to assist passengers effectively, manage cabin safety procedures, and handle any emergency situations that may arise.

The two flight attendants’ requirement is aligned with safety standards that aim to provide a higher level of service to ensure passenger security. The regulations take into account the size of the aircraft, passenger load, and the need for comprehensive coverage in handling cabin operations safely.

In contrast, having one flight attendant would not provide adequate coverage for aircraft of that size, especially if the number of passengers exceeds a certain threshold. Hence, while two is established as the minimum, it is a necessity for operational safety and efficiency in managing a larger number of passengers onboard an A321.
