An actuating system for an actuatable door and to an actuatable door having such an actuating system. The actuating system comprises a rotatable latching shaft, a rotatable locking shaft, a latching device, comprising a latch, and a locking device. The latch is adapted to maintain the actuatable door in a closed position. The locking device comprises a locking cam, that is mounted to the locking shaft and that is adapted to engage with the latch in a closed and latched position, and a latch securing lever, that is driven by the locking cam and that is adapted to engage with the latch to maintain the latch in a closed and secured position.

An embodiment is a system including an external passenger seating unit comprising at least one seat; and a translation mechanism for translating the external passenger seating unit between a first position in which the external passenger seating unit is stowed in a payload bay of an aircraft and a second position in which the external passenger seating unit is deployed external to the aircraft for accommodating at least one passenger.

Examples provide a door assembly including a dual operation slide device for a sliding privacy door associated with a seat unit. The door assembly includes a sliding door movably mounted to a door support member of a seat unit. The door slides laterally between a retracted position and a deployed or partially deployed position. The dual operation slide device includes a trigger and release mechanism for switching the door assembly from a primary track system used during a normal operation mode to a secondary track system used during a backup operation mode if the primary track becomes jammed or otherwise malfunctions based on manual activation of a release lever or force applied activation. The dual operation slide device enables a user to return the sliding door to a retracted position after a failure of the primary slide units to operate in the normal operational mode.

An actuating system for an actuatable door and to an actuatable door having such an actuating system. The actuating system comprises first and second rotatable latching shafts, a coupling link, first and second pivotable mechanical transmission elements that are mounted onto first and second rotatable latching shafts, respectively, and first and second latching members. First and second latching members are non-rotatably mounted to the second rotatable latching shaft and adapted for latching the actuatable door in a closed position. A first rotation of the first rotatable latching shaft results in pivoting of the first and second mechanical transmission elements and a second rotation of the second rotatable latching shaft, which causes a third rotation of first and second latching members.

Aircraft door (1) having an inside door opening lever (6) coupled to a vent flap (5) by a conditional opening mechanism having two modes and including a flap stop (20) to cooperate with a stop surface (21). The stop (20) has a first trajectory, the stop surface (21) being arranged outside this first trajectory of the flap stop (20). The stop (20) has a second trajectory, the stop surface (21) being arranged on this second trajectory of the flap stop (20).

An aircraft is equipped with an auxiliary access control barrier (AACB) to prevent access to an area of the aircraft. The AACB includes laterally extendable door panels that are slidably attached to each other to vary a width of the AACB, a hinge by which the door panels are pivotably attached to the aircraft, such that the door panels are pivotable between a deployed position, in which the door panels are positioned across the opening to prevent passage through the opening and in which the AACB has a first width, and a stowed position, in which the door panels are positioned to allow passage through the opening and in which the AACB has a second width, and one or more locks to prevent relative motion between the door panels to fix the width of the AACB and/or to secure the AACB within the opening in the bulkhead.

A plug door assembly for a pressurized aircraft is provided. The door assembly includes a surround and a door, and connector assemblies along the edges that act to transfer in-place stresses directly across the fuselage opening via the door, as well as stops that react redial loads generated by cabin pressure. The door assembly obviates the need for a separate frame to transmit stresses around the perimeter of the fuselage opening.

An aircraft door arrangement, comprising a door pivotable between closed and open positions, a frame section in a door opening region, and an articulation arrangement connecting the door and frame section. First and second arms are mounted on the frame section, rotatable about first and second axes, respectively. Third and fourth arms are mounted on the door, rotatable about third and fourth axes, respectively. The second arm, at a first position, is rotatably coupled to the fourth arm about a fifth axis, and at a second position, closer to the second axis, is rotatably coupled to the third arm about a sixth axis. The third arm, at a third position, is rotatably coupled to the first arm about a seventh axis, and at a fourth position, closer to the third axis, is rotatably coupled to the second arm about the sixth axis. All axes are oriented substantially parallel.

A flight deck barrier door for an aircraft, the flight deck barrier door including a door frame and a door panel in the door frame. The door panel has a plurality of vents. The door panel and door frame have a minimum total vented surface area of 1000 square inches.

An information projection and control system for projecting information onto a projection area provided by a vehicle door, comprising at least one control unit that generates information, for projection onto the projection area; at least one projection device that projects the generated information onto the projection area; and at least one movement sensor that detects movements in a sensing area associated with the projection area, wherein the at least one control unit is adapted to control generation of the generated information on the basis of the detected movements.
