A reconfigurable interior sidewall system includes one or more simply
curved sidewall panels, each curved around the fuselage but
longitudinally linear and providing a consistent mating surface for
monuments. Panel openings are provided in each panel so that inner window
assemblies may be installed for opposing structural windows, each inner
window assembly having outward sculpturing for additional cabin room. A
cover plate is also provided for flush insertion into the opening to fill
the opening when it is not needed and to provide a constant profile for
cabin monuments whenever the layout of the cabin changes. This results in
the production of fewer parts as well as facilitating faster and less
expensive interior reconfigurations.
