1. An aircraft comprising:
a fuselage, and
a plurality of load-bearing structures within the fuselage supporting a floor,
the floor comprising:
a plurality of beams parallel to each other and perpendicular to a longitudinal direction,
a plurality of rails parallel to each other and to the longitudinal direction,
at least one fixed floor part, and
at least one movable floor part that is movable relative to the at least one fixed floor part, having at least one longitudinal edge parallel to the longitudinal direction;
wherein each of said plurality of beams comprises:
a first beam portion secured to the fixed floor part, and
a second beam portion secured to the movable floor part,
the first and second beam portions being aligned, positioned end to end and separated at a cutting plane positioned in line with the at least one longitudinal edge of the at least one movable floor part,
wherein at least one of said plurality of rails comprises at least one first rail portion secured to the at least one movable floor part and at least one second rail portion secured to the at least one fixed floor part of the floor, extending said first rail portion,
wherein the floor comprises at least one hinge connecting the at least one movable floor part and the at least one fixed floor part and having a pivot axis parallel to the longitudinal direction, said hinge comprising, each said plurality of beams, a pivot link which connects the first and second beam portions, and
wherein each said first beam portion is fastened to a first load-bearing structure of the plurality of load-bearing structures, and each said second beam portion rests on a second load-bearing structure of the plurality of load-bearing structures without being fastened thereto,
wherein each said second beam rests on the second load-bearing structure without being fastened thereto at a location on each said second beam between first and second right- and left-hand lateral edges of the floor,
wherein the floor comprises:
the at least one movable floor part comprises first and second movable floor parts,
the first movable floor part comprising:
a left-hand longitudinal edge positioned at the left-hand lateral edge of the floor and a right-hand longitudinal edge spaced apart from and offset towards the left in relation to a first rail,
the second movable floor part comprising:
a right-hand longitudinal edge positioned at the right-hand lateral edge of the floor, and
a left-hand longitudinal edge spaced apart from and offset towards the right in relation to a second rail,
wherein the left-hand longitudinal edge is positioned at the left-hand lateral edge of the floor and the right-hand longitudinal edge is positioned at the right-hand lateral edge of the floor are adjacent of the fuselage,
said aircraft further comprising:
a central wing box, and
a main landing gear casing,
wherein the at least one movable floor part is positioned above at least one of the central wing box or the main landing gear casing.
