The disclosure relates to a door locking assembly for locking a door of an aircraft, comprising a locking hook adapted for blocking in a locking position a lockable arm of a door of an aircraft; a release lever connected to the locking hook for moving the locking hook from a releasing position into the locking position in response to being actuated by a lockable arm of a door of an aircraft; an operating handle connected at least to the release lever and rotatable for moving the locking hook from the locking position to the releasing position; and a locking indicator connected to the locking hook for indicating positioning of the locking hook in one of the locking position or the releasing position.

Embodiments are directed to systems and methods for a sliding door in a pressurized aircraft. In one embodiment, an aircraft comprises a fuselage having a door opening, and a door configured to slide into the door opening from within the fuselage, the door held in a closed position in the door opening by excess air pressure within the fuselage during operation of the aircraft.

A separating element (10) for a platform cabin comprises at least one leaf (20), mounted movably between a closed position and an open position, the leaf (20) being subjected to a return force toward its open position, and, for the or each leaf (20), a return member (36) for returning the leaf (20) toward its closed position, said return member (36) comprising a first end (60) articulated at an articulation point (64) movable jointly with the leaf (20). This return member (36) also comprises a second end (62) mounted movably relative to the partition (12) between an active position and an inactive position, such that when the leaf (20) is open and the second end (62) is in the active position, the return member (36) is in a working configuration in which it exerts, on the leaf (20), a return force returning the leaf (20) toward its closed position, and when the leaf (20) is open and the second end (62) is in the inactive position, the return member (36) is in a second configuration in which it does not exert a force returning the leaf (20) toward its closed position.

A versatile door system for an aircraft includes forward and aft door assemblies. The forward door assembly includes a forward hingeable door hingeably coupled to the airframe proximate a forward location of an aircraft opening and a forward slidable door slidably coupled to the forward hingeable door. The aft door assembly includes an aft hingeable door hingeably coupled to the airframe proximate an aft location of the aircraft opening and an aft slidable door slidably coupled to the aft hingeable door. In a closed configuration, the forward hingeable door, the forward slidable door, the aft hingeable door and the aft slidable door are securably disposed within the aircraft opening. In operation, the forward hingeable door, the forward slidable door, the aft hingeable door and the aft slidable door are individually operable to collectively provide access to a selectable width of the aircraft opening.

In some examples, a track comprises a plurality of members coupled to one another. The plurality of members comprises a first member, a second member, and a third member. The first member is operable to couple the track to an aircraft. The second member forms a first rail. The third member forms a second rail. In addition, the third member comprises at least a portion of an outer mold line of the aircraft. Moreover, the third member is operable to support a step load. The first rail and the second rail are operable to guide movement of an aircraft component along the track.

A latch arrangement for a door includes a plurality of steps disposed at an interior of the door. One of the plurality of steps is rotatable relative to the door between a first position and a second position. The door is movable between a closed position and an open position. A latch is in operable communication with the rotatable step. The latch is engageable with a latch receiver to lock the door in the closed position in response to the rotatable step being in the first position. The latch is disengageable from the latch receiver when the step is in the second position thereby allowing the door to move to the open position.

A handle attachment assembly that includes first and second insert members, and a handle assembly that includes a cover and a main body portion. The main body portion includes a handle portion and first and second attachment portions extending from the handle portion. The cover is removably connected to the main body portion and the main body portion and the cover cooperate to define a handle interior. The first and second attachment portions include first and second attachment members, respectively. The first attachment portion and the first insert member are secured together by a first fastener, and the second attachment portion and the second insert member are secured together by a second fastener.

A rotary wing aircraft with a fuselage that is equipped with at least one rail, comprising at least one sliding element, in particular a sliding door or a sliding window, that is slidably supported by the at least one rail, wherein the at least one sliding element is at least slidable along the at least one rail by means of an opening sliding movement into an opening movement direction from a fully closed position into a fully opened position, wherein a dampening unit is provided that dampens the opening sliding movement of the at least one sliding element upon reaching of the fully opened position.

Systems and methods include providing an aircraft with a fuselage having a sliding door system disposed on at least one side of the fuselage. The sliding door system includes a forward sliding door having an upper slide rail and a lower slide rail, a rearward sliding door having an upper slide rail and a lower slide rail, an upper rail coupled to each of the upper slide rail of the forward sliding door and the upper slide rail of the rearward sliding door, a lower rail coupled to each of the lower slide rail of the forward sliding door and the lower slide rail of the rearward sliding door, and a plurality of actuators coupled to each of the upper rail and the lower rail and configured to displace and retract the forward sliding door and the rearward sliding door linearly with respect to the fuselage.

Systems for latching and locking an aircraft door and associated methods are disclosed. The system comprises a latch and a lock. The latch can be configurable between: a latched configuration where the latch interferes with a lift mechanism for causing lifting of the aircraft door to permit opening of the aircraft door; and an unlatched configuration where the lift mechanism is permitted to cause lifting of the aircraft door. The lock can be configurable between: a locked configuration where a configuration change of the latch from the latched configuration to the unlatched configuration is prevented; and an unlocked configuration where the configuration change of the latch from the latched configuration to the unlatched configuration is permitted.
