FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering. Floor system comprises lengthwise beams secured at fuselage section top or bottom areas. Support element is arranged at lengthwise beams. One crosswise beam to support and secure floor elements is placed at two opposed support elements. Floor system represents a self-bearing structure disengaged from fuselage section as the main structure. Floor element supports functional element (armchair, set of armchairs, kitchen module and/or wc) to allow distribution of load on large area in floor system. Floor element features width corresponding to spacing between two lengthwise channels and length corresponding to spacing between two crosswise beams.
EFFECT: possibility to modify floor system in wide limits irrespective of static characteristics and limiting conditions of fuselage section, uniform load distribution, lower weight.
