What is the maximum load capacity of the main cabin door?

The maximum load capacity of the main cabin door is critical for ensuring safe and efficient boarding and deboarding of passengers. The correct answer reflects that the main cabin door can accommodate up to 1000 pounds or the equivalent of 4 passengers. This capacity is designed to maintain structural integrity while allowing for safe egress and ingress in various operational scenarios, including emergency situations.

Understanding the load capacity is essential for personnel involved in passenger loading and unloading, as exceeding this limit could compromise the door’s function and safety features. In contrast, the other options present higher weights and passenger equivalents that exceed the structural specifications intended for the cabin door, which could lead to potential risks or failures during operation. Therefore, it is imperative to adhere to the provided maximum load capacity to ensure safety and compliance with operational standards.
