DOORS
On the A380-800 there are sixteen pas senger/crew doors and emergency exit doors. They are located on the main and the upper deck as follows:
- eight passenger/crew doors on the main deck, four on each side of the cabin,
- two emergency exit doors upon the wing, one on each side of the cabin , - six passenger/crew doors on the upper deck, three on each side of the cabin.
The passenger/crew doors can be u sed as emergency exits if needed. The emergency exit doors have the same design principle as the
passenger/crew doors. The doors on the right hand side of the fuselage are a mirror image of those on the left hand side.

The main deck doors have an external skin panel made of aluminum alloy. It is riveted to six horizontal beams, six vertical frames and two edge members, all made of aluminum alloy. During opening/closing movements, the door is supported by a support arm made of Carbon Fiber Reinforced Plastic (CFRP) and guided by two guide arms. An emergency exit slide system is mounted on the main deck doors.

DOORS (continued) UPPER DECK DOORS UPPER DECK DOORS
The upper deck doors have the same design principle as the main deck doors. The difference between the main and the upper deck doors is in their geometrical forms. The upper doors have seven horizontal beams and only five vertical frames. Due to their position on the fuselage, the upper deck doors are more inclined that the main deck doors, and the support arm is located in the lower part of the door.
The emergency exit slide system is not mounted on the upper deck door, but it is located underneath the doo r in a separated compartment in the fuselage.

Forward and aft cargo doors have the same design principle. They have internal and external skin panels made of aluminum alloy and riveted to vertical frames and horizontal beams. The difference between the forward and the aft cargo door is that the forward cargo door has nine vertical frames while the aft cargo door has only eight vertical frames. These doors are hinged on their upper end and latched by hooks on the lower end. The piano hinges on the upper end make a good load distribution possib le. The forward and aft cargo doors are hydraulically actuated.
