The intermediate floor 12b partitions an interior of a fuselage into two sections 6 and 7 including the upper section 6 that forms a cabin and the lower section 7 that has an open bottom 23 leading to outside via a bottom surface of a fuselage. The intermediate floor 12b provides a loading flat surface in the upper section 6 having a pseudo-floor 27 constituted from replaceable slabs 28 to which various equipment is attached. The intermediate floor 12b also forms a fixed member that can suspend facilities 16 and 17 to be suspended and the facilities are accessible from outside of the fuselage through the open bottom 23.SELECTED DRAWING: Figure 2 |
