Which cargo door can be manually operated and opened from both inside and outside?

The Bulk Compartment Door is unique among the options because it is designed to be manually operated from both the inside and outside of the aircraft. This feature provides versatility and accessibility when loading or unloading cargo. The ability to operate it from either side enhances the efficiency of cargo handling, especially in varied operational environments or in cases where ground support might be limited.

The other doors mentioned serve different functions and typically do not have the same dual-access manual operation feature. For instance, cargo doors like the Forward and Aft Cargo Doors are generally operated through powered means and may not offer manual access from both sides. Emergency Exit Doors are designed primarily for evacuation and safety purposes and are not intended for routine cargo access. This focus on operational access positions the Bulk Compartment Door as a critical component in the A320’s cargo handling procedures.
