Looking at the image above let us say the pilots are able to land this aircraft with wheels up in an emergency situation.
Generally they carry bending moments shear forces and torsional loads which induce axial stresses in the stringers and skin together with shear stresses in the skin.
Load supporting aircraft flooring systems preferably are provided with a longitudinally separated series of transverse bridges having an upper doubler flange which defines latitudinally separated upper openings and a latitudinally separated series of beams which include an upper flange and.
Manufacturers use some system of station marking.
An integrated floor for an aircraft fuselage includes a composite panel forming a floor surface and composite beams bonded to the floor panel.
Typically it extends from a flat vertical surface such as a wall to which it must be firmly attached.
