4. The floor module according to claim 1 , wherein the cover element is formed from a first material and the floor element is formed from a second material, the first material forming the cover element having a thickness that is at least twice the thickness of the second material forming the floor element.
5. The floor module according to claim 1 , wherein the cover element has, on at least one edge, an upwardly curved section for covering a portion of a fuselage of an aircraft.
6. The floor module according to claim 1 , wherein connecting elements are provided between the cover element and the floor element.
7. The floor module according to claim 6 , wherein the connecting elements comprise tube sleeves, by means of which fasteners are adapted to fasten tie-down elements directly to transverse beams of the cargo hold.
8. The floor module according to claim 1 , wherein the cover element is fixedly connected to the floor element for common handling.
9. The floor module according to of claim 1 , wherein the hybrid composite part of the cover element and/or the floor element comprises carbon fibres and/or glass fibres.
10. The floor module according to claim 1 , wherein the rail which is attached to the floor element is provided with a freight-handling system.
11. The floor module according to claim 1 , wherein the cover element comprises a peripherally mounted stop rail.
12. The floor module according to claim 1 , wherein the floor element comprises connection chambers for connecting and/or extracting connection cables for freight-handling systems.
13. A use of a floor module according to claim 1 in the region of a cargo hold door.
14. The floor module according to claim 1 , wherein the cover element is formed from a first material and the floor element is formed from a second material, the first material forming the cover element having a thickness that is at least three times the thickness of the second material forming the floor element.
15. The floor module according to claim 1 , wherein the cover element is formed from a first material and the floor element is formed from a second material, the first material forming the cover element having a thickness that is at least five times the thickness of the second material forming the floor element.
