Abstract: The invention relates to a latching box for selectively retaining a movable element such as an undercarriage or a hatch in position, the box comprising a body carrying: a hook pivotally mounted about a first pivot axis between an engaged position and a disengaged position relative to the movable element; a locking member pivotally mounted about a second pivot axis parallel to the first pivot axis to pivot between a position for blocking the hook in the engagement position and a release position for releasing the hook; and at least one cam actuator in which the cam co-operates operationally with the locking member to move it towards the release position. The cam of the actuator is a cylindrical cam mounted to rotate about an axis of rotation orthogonal to the first and second pivot axes.

Abstract: The invention relates to a method for controlling the manoeuvring of the landing gear of an aircraft, in which at least one of the steps of pulling on the doors of the bay to relieve the door retaining hook, actuating the door hook or hooks to free the doors and opening the doors is executed in response to the detection of a flight situation suitable for the occurrence of a manoeuvre order, even before the manoeuvre order is received.

Abstract: The invention relates to a device for maneuvering, on the ground, a door of an aircraft landing gear, the door being linked with door maneuvering means and uplock means for locking the door when it reaches the closed position, at least one unlocking electromechanical actuator arranged to act upon the uplock means with a view to deactivating them during opening of the door in flight. According to the invention, the device comprises control means 17 which can be operated by an operator on the ground in order to control at least: an opening sequence during which the unlocking electromechanical actuator is actuated in order to deactivate the uplock means, a closing sequence during which the maneuvering means are actuated in order to close the door again.

Abstract: A control box for selectively delivering orders to receivers (8, 12). The control box comprises a shaft (14) mounted to turn about an axis of rotation (X), while being capable of sliding along the axis (X) between a rest position towards which it is urged by return means (24), and an active position. An order delivery apparatus (16, 11) co-operates with the shaft (14) to deliver orders as a function of the angular position of the shaft (14). A rotary drive (15) causes the shaft to turn. A safety actuator (23) causes the shaft to slide from the rest position in which anti-rotation structure (27, 28) prevents the shaft from turning to the active position in which the anti-rotation structure (27, 28) leave the shaft free to turn under drive from the rotary drive (15).

Abstract: The invention provides a control box for selectively delivering orders to receivers (8, 12), the control box comprising: a shaft (14) mounted to turn about an axis of rotation (X), while being capable of sliding along said axis (X) between a rest position towards which it is urged by return means (24), and an active position; order delivery means (16, 11) co-operating with the shaft (14) to deliver orders as a function of the angular position of the shaft (14); rotary drive means (15) for causing the shaft to turn; and safety actuation means (23) for causing the shaft to slide from the rest position in which anti-rotation means (27, 28) prevent the shaft from turning to the active position in which the anti-rotation means (27, 28) leave the shaft free to turn under drive from the rotary drive means (15).
