Abstract: An aircraft having a hatch and a fall-protection device includes a structure comprising a roof pierced with an opening, a cover plate, and a lock provided to adopt a locking position, in which the lock holds the cover plate in the closed position in the opening, or, alternatively, an unlocked position, in which the lock does not hold the cover plate. The aircraft further comprises at least one fall-protection device provided so that, when the lock moves into the unlocked position, it is in a first position to allow movement of the cover plate under the influence of gravity from its closed position to an intermediate position, in which the cover plate is suspended from the structure and then moves from the first position into a second position, during which movement the cover plate moves from the intermediate position into an open position, no longer attached to the structure.

Abstract: A case including: a vessel, a cover mounted to be moved in rotation on the vessel via a hinge system which has a hinge axis and at least one hinge, wherein each hinge has a first portion which is fixedly joined to the vessel, a second portion) which is fixedly joined to the cover and a connector which assumes alternately an operating position in which the connector ensures the connection between the second portion and the first portion to allow for rotation of the second portion relative to the first portion about the hinge axis and, alternatively, a safety position in which the connector dissociates the second portion and the first portion.

Abstract: An airplane flight deck which includes an escape opening closed off by an emergency door and an emergency hatch. The emergency hatch comprises a sheeting and a locking/unlocking mechanism configured to take up a locked state in which the sheeting closes off the escape opening and an unlocked state in which the sheeting frees the escape opening.
