Abstract: A method and apparatus for a hierarchical access system for a compartment. The hierarchical access system comprises a moveable barrier, a locking mechanism, and a control unit. The moveable barrier is capable of preventing access to at least one of a first space and a second space in the compartment in the lavatory when the moveable barrier is in a closed position. The locking mechanism is capable of securing the moveable barrier in the closed position. The control unit is capable of unlocking the locking mechanism in a manner that provides different levels of access to the first space and the second space in the compartment in response to receiving an access request.

Abstract: An emergency equipment system comprising an elongate member, an emergency equipment package, and a cutter. The elongate member may have a first end and an angled end. The emergency equipment package may have a sleeve on one side capable of receiving the elongate member from the angled end. The cutter may be attached to a side of the elongate member and may be capable of cutting the sleeve.

Abstract: A composite tie rod comprises an open lattice body formed of interlaced filaments held in a solid matrix. A pair of composite fittings bonded to the ends of the body rigidly connect rod ends with the body. The rod ends form attachment points on the tie rod.

Abstract: Disclosed is an apparatus and method for supporting the center stowage bins, center monuments, aircraft systems, and overhead modules, such as attendant rests, for commercial aircraft. Use of an overhead lattice support structure provides an efficient structural support system for the passenger luggage center stowage bins, and also provides the necessary overhead space to accommodate modules, such as crew rests, as well as essential aircraft systems, including ducts, tubes, electrical wiring, and electrical equipment. The overhead lattice support structure also simplifies aircraft assembly operations by allowing more systems (ducting and electrical) to be pre-installed in a back shop rather than in a final assembly line.
