- seat rails are regularly provided on the cabin floor, at predetermined connection points fixed to the cabin floor or are connected to the aircraft structure and enable variable attachment of passenger seats to it.
- connection points are provided on the aircraft structure, frequently on the frames of the aircraft fuselage, for the luggage storage compartments, the wall paneling and cable and ventilation lines. These connection points are usually repeated at least in areas of a constant fuselage cross-section in the longitudinal direction of the aircraft fuselage at regular intervals, which enables the use of standardized assemblies, in particular including luggage compartments and/or wall panels.
- connection points directly provided by the manufacturer on the cabin floor are basically sufficient to equip the aircraft cabin according to the originally intended purpose of an aircraft, the connection points for cabin equipment for a different purpose are generally not optimal.
- an airliner designed for commercial passenger transport to a so-called VIP aircraft with individual cabin equipment (such as a government aircraft) or converted into a hospital aircraft the connection points provided for the configuration of the aircraft cabin as a typical passenger cabin for the cabin equipment are based on their respective, on the equipment of a passenger cabin aligned position often unsuitable .
- connection points can be introduced into the aircraft structure, which enable the desired cabin equipment to be attached to it.
- Disadvantage of this State of the art is that the provision of additional or alternative connection points is not possible in every case, at least at the desired position and often requires complex approval by the responsible supervisory authorities.
