A privacy door assembly for installation in an aircraft relative to a flight deck door of the aircraft includes a door frame having a first post and a second post, where the second post comprises a latch recess. The privacy door comprises a latch positioned on an edge of the privacy door and arranged to engage the latch recess when the privacy door is in a closed position within the door frame. An access door is positioned in the privacy door, where the access door is rotatable from a closed position to an open position in a forward direction. A first mechanical door handle system including a mechanical combination lock is positioned on an aft side of the privacy door and coupled to the latch, and a second mechanical door handle system is positioned on a forward side of the privacy door and coupled to the latch.

An aircraft and system of doors for providing security to a flight deck of the aircraft, and methods for operating the same, are provided. A passenger cabin is separated from a flight deck by an aisle that includes doors at either end. The doors are locked by a controller and one of the doors may only be unlocked, during a flight, if the remaining door is locked. As a result, a pilot can access a lavatory in the aisle in a secure manner. Additionally, the door closest to the passenger cabin may include a window that allows the pilots to view the passenger cabin through a peephole in the flight deck door. The controller may selectively dim or block a view through the window to prevent monitoring of the pilots' movements onto and off of the flight deck.

An aircraft comprises a cockpit, a passenger cabin, and an aircraft monument. The aircraft monument contains a hallway connecting the cockpit and the passenger cabin, wherein the aircraft monument is formed of a plurality of walls joined together to form a unitary structure. The plurality of walls includes a first wall having a first doorway and a second wall having a second doorway. A secondary security door is within the second doorway.

An access device enables controlled or secure communication between different areas of an enclosure, and in the example illustrated in the present application of an aircraft, while providing reduced size. The access device includes a folding door which, when in folded position, allows at least one of said openings to be closed and, when in deployed position, forms a security vestibule with at least one movable shutter allowing said opening created by the deployment of said folding door to be closed. By superimposing the main components of the security vestibule that said components allow to close, the device frees up the adjoining cabin space when the security vestibule is not in use.

A privacy door assembly for installation in an aircraft relative to a flight deck door of the aircraft includes a door frame having a first post and a second post, where the second post comprises a latch recess. The privacy door assembly also includes a privacy door rotatably coupleable to the first post via a set of hinges, where the privacy door comprises a decompression latch arranged to engage the latch recess when the privacy door is in a closed position within the door frame, and where the decompression latch is configured to disengage from the latch recess in response to a decompression detected on a forward side of the privacy door.

A secondary barrier system for an aircraft includes a secondary barrier gate including a telescoping structure is disclosed. The secondary barrier gate may include a plurality of crossmembers, and at least one of the plurality of crossmembers may include a panel treatment. The secondary barrier gate is rotatable between a stowed position and a deployed position and extendable between a retracted length and an extended length. The secondary barrier gate is securable in the stowed position and the deployed position. The secondary barrier gate may be rotatably mounted to a ceiling or within a crown area of the aircraft. The secondary barrier system may also include a stowage latch actuatable to selectively release and/or secure the secondary barrier gate from/in a stowed position and a deployment latch actuatable to selectively release and/or secure the secondary barrier gate from/in one of a retracted length or an extended length.
