Which of the following is a correct statement regarding the load capacity of cabin doors?

The correct statement regarding the load capacity of cabin doors is that the load capacity includes both passengers and cargo. This is essential to understand because the cabin door's structural integrity must support not only the weight of the passengers entering and exiting the aircraft but also any cargo or baggage placed near the door area.

The door's design takes into account various loads it may encounter during operations, including dynamic forces during flight and static loads while on the ground. Ensuring that both passengers and cargo are considered in the load capacity helps maintain safety and compliance with operational limits.

Recognizing that both passengers and cargo contribute to the overall load is crucial during the boarding process, as exceeding these limits could compromise door functionality or safety protocols. This highlights the importance of managing not just passenger numbers but also the distribution and weight of cargo in proximity to the cabin doors.
