In order to comply with statutory regulations, the invention concerns an emergency exit suitable for occupying two different configurations and which is used during a land or maritime evacuation of an aircraft. The door of the emergency exit is formed of one upper element (20) able to pivot inside the cabin (12) and one lower element (22) able to pivot outside the cabin. A main locking system (64), accessible from inside and outside the cabin and normally locked, controls the opening of the upper element (20) and then of the lower element (22) during a land evacuation. A secondary locking system (26), normally locked, is activated prior to a landing so that the lower element (22) then remains closed when the main locking system (64) is activated.
