Where is the safety valve located?

• A. Aft left corner of the cargo door
• B. Aft right corner of the cargo door
• C. Fore left corner of the cargo door
• D. Fore right corner of the cargo door

Answer: (A)

The safety valve is placed in the aft left corner of the cargo door because this location minimizes interference with the door opening and sealing hardware while providing an unobstructed vent path outward. Placing it here keeps vented air or fumes away from the cockpit and cargo space and aligns with typical exterior venting routes, making maintenance and inspection straightforward. Placing the valve in fore corners could put it too close to hinges or mechanisms or vent toward areas where it could affect door operation or interior spaces, and the right-side position may encounter equipment or access constraints. For these reasons, the aft left corner is the standard, safest placement.
