Abstract: 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.

Abstract: A rotating retractable step system positioned within a cutout of a wall is presented. The rotating retractable step system comprises a foot pedal and a support shaft. The foot pedal is configured to be stowed in a vertical orientation within the cutout of the wall, and to rotate between the vertical orientation and a horizontal orientation. The support shaft is associated with the foot pedal, such that movement of the support shaft extends the foot pedal outwardly away from the cutout, or retracts the foot pedal towards the cutout.

Abstract: Secondary barriers for aircraft are disclosed. An example secondary barrier includes a plurality of tracks to mount to a first monument in a cabin of an aircraft and a plurality of rods, where respective ones of the rods slidably engage respective ones of the tracks. The secondary barrier includes a panel coupled to respective ends of the rods. The rods to move relative to the tracks between a stowed position and a deployed position. The panel in the deployed position is to interface with a second monument in the cabin opposite the first monument. The rods are to extend between the first monument and the second monument when the secondary barrier is in the deployed position.

Abstract: A chiller galley cart includes a plurality of walls defining an interior cavity, a supply valve defined in one wall of the plurality of walls, and a return valve defined in one wall of the plurality of walls. The supply valve and the return valve are configured to couple to a chiller positioned in the interior cavity to provide cooled airflow from the chiller galley cart. A method for cooling a demand galley cart positioned in a cart compartment of a galley includes positioning a chiller galley cart in the cart compartment having a chiller positioned in the interior cavity coupled to the supply valve and the return valve and coupling the supply valve to a supply port of the galley and coupling the return valve to a return port of the galley.

Abstract: A compartment door of a galley within an internal cabin of a vehicle (such as an aircraft) includes a front panel having a front outer surface, and a footstep system secured to the front panel. The footstep system is moveable between a retracted position and an extended support position. The footstep system is vertically oriented in the retracted position. The footstep system outwardly extends and folds to provide a step surface in the extended support position.
