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.

NACELLES DESCRIPTION (3) THRUST REVERSER AND FAN EXHAUST C OWL THRUST REVERSER The thrust reverser is located behind the fan cowls. It consists of a fixed structure (inner fixed structure), which provides su pport for the thrust reverser actuators, and a translating cowl. In forward thrust configuration it encloses the engine core with an aerodynamic flow path, and uses the translating cowl to provide a fan exhaust duct and a nozzle exit. In reverse thrust configuration, the blocker doors reverse the fan flow to forward direction trough cascades, while the translating cowl moves aft in order to let the flow pass trough. The inner fixed structure has two halves, each made of CFRP sandwich construction. It is hinged to the pylon at the top with the 12 o'clock hinge beam and is locked at the bottom centerline with the 6 o'clock latch beam (aluminum alloy parts). Each half is electrically opened and held in position by HOR (not illustrated). The forward frame, designed as a torsion box, is fitted to the forward of the inner fixed structure and made of CFRP. Its main functions are to attach the thrust reverser to the engine and to provide structural support to the actuation system and the cascades. The following elements are attached to the inner fixed structure: - the cascades (CFRP), - the blocker doors (CFRP), hinged to the translating cowl and attached to links, - the translating cowl. The translating cowl is an assembly of: - the acoustic barrel (CFRP sandwich), which enhance noise reduction, - the external barrel (CFRP).
