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.
