<p>In order to satisfy the regulations, an emergency exit is proposed which is able to take up two different configurations, according to whether it is used for a land or ditching evacuation from an aircraft. The door of the emergency exit is formed by an upper element (20), able to pivot towards the inside of the cabin (12), and by a lower element (22), able to pivot towards the outside of the cabin. A main locking system (64), accessible from the inside and the outside of the cabin, and normally locked, controls the opening of the upper element (20), then of the lower element (22), during a land evacuation. A secondary locking system (26), normally unlocked, is actuated before ditching, in such a way that the lower element (22) then remains closed when the main locking system (64) is actuated. <IMAGE></p> |
