Abstract: Embodiments of systems, devices, and methods are described that relate to module structures for use in forming a cabin interior of an aircraft. Many embodiments relate to a support structure including a lattice configurable to provide a standardizable frame for connection to the interior of the aircraft and to provide a space within the frame in which module fixtures can be positioned and secured to the frame. Embodiments of the support structure can include a floor with a number of structures and devices that can be used to provide support for the module and secure the module to the floor of the aircraft fuselage. Embodiments of transport systems for the modules are also described and such can be integrated with the floor of the module such that the modules transport mechanism, or a significant portion thereof, is contained within the module itself.
