 3. System Description__________________
 The rapid-decompression safety-system prevents a pressure difference between different closed areas in the aircraft (for example; cockpit/cabin, cabin/cargo compartment) if a rapid decompression occurs. This prevents structural damage to the fuselage and damage to the equipment and furnishings, installed in these areas.
 The rapid-decompression safety-system has: - Rapid-decompression panels (cargo compartments). - Dado panels (cabin) (Ref. 25-23-00). - Air grills (stowages and lavatories). - Cockpit door (Ref. 52-51-00).
