Abstract: An aircraft fuselage assembly includes a primary structure with first and second rows of support elements extending parallel to a longitudinal axis and into an interior space of the fuselage where they have a free end. The free ends of the first and second rows are spaced from one another to from a free space below a common plane of the free ends and extending to the primary structure. A cargo floor assembly with at least one first cargo floor element is fixedly connected to the free ends of the first row in the common plane and at least one second cargo floor element fixedly connected to the free ends of the second row in the common plane. At least one central cargo floor element is arranged between the first and second lines and is releasably connected to the support elements of the first and second rows.

Abstract: A system for moving loads in an aircraft, comprising a cargo hold floor and at least one roller track comprising a plurality of rollers, defining a plane of movement for the load, arranged one behind the other in the hold floor. At least one guide track is provided in the floor extending parallel to the roller track. At least one transfer vehicle is detachably received in the guide track, movable along the guide track. At least one locking device is configured, in a locking position, to block movements of a load relative to the roller track parallel to the movement plane and perpendicular to the movement plane and, in a release position, to allow relative movements. The locking device is configured to be actuated by a transfer vehicle in the guide track to shift the locking device out of the release position into the locking position, or vice versa.
