The invention relates to floor heating for an aircraft which has a floor (20) made up of heatable panels (18). In order to be able to heat up the panels (18) in an energy-saving way, the same are provided with hollow chambers (26) which pass through them, wherein a feed line (28) for warm waste air
The invention relates to floor heating for an aircraft which has a floor (20) made up of heatable panels (18). In order to be able to heat up the panels (18) in an energy-saving way, the same are provided with hollow chambers (26) which pass through them, wherein a feed line (28) for warm waste air originating from the cooling of the aircraft's electronic equipment which is connected to the first hollow chambers (26), conveys hot air to the first hollow chambers (26) when the floor heating system is in operation.

The invention claimed is: 1. Aircraft floor heating comprising: an aircraft with a fuselage having a forward cockpit section and a cabin section located aft of the cockpit section and extending along the length of the aircraft, the cockpit section including a cockpit and an avionics bay containing
The invention claimed is: 1. Aircraft floor heating comprising: an aircraft with a fuselage having a forward cockpit section and a cabin section located aft of the cockpit section and extending along the length of the aircraft, the cockpit section including a cockpit and an avionics bay containing electronic equipment; a floor within the cabin section made up of heatable panels defining a plurality of first hollow chambers formed integrally with the panels and wherein each hollow chamber has a first end proximate to the cockpit section and a second end distal of the cockpit section; and a feed line operatively connected to the avionics bay and the first ends of the first hollow chambers and providing fluid communication therebetween, the feed line supplying warm waste air to the first ends of the hollow chambers, the warm waste air having originated from the cooling of the electronic equipment contained in the avionics bay, whereby the warm waste air travels through the first hollow chambers along the fuselage of the aircraft and heats the floor of the cabin section, a cargo door located in the fuselage aft of the first hollow chambers, the cargo door including heatable panels defining a plurality of second hollow chambers formed integrally with the panels, the second hollow chambers residing in fluid communication with the second ends of the first hollow chambers, the second hollow chambers being in fluid communication with one of (a) the cabin section, and (b) the outside of the aircraft, whereby warm waste air flows from the second hollow chambers to one of the cabin section and the outside of the aircraft. 2. Floor heating in accordance with claim 1, characterized in that the first hollow chambers extend in the longitudinal direction of the aircraft inside the panels. 3. Floor heating in accordance with claim 1, characterized in that the second hollow chambers terminate into the cabin section aft of the cargo door. 4. Floor heating in accordance with claim 1, further comprising: a first bleed air feed line operatively connecting the first ends of the first hollow chambers to a first supply of hot bleed air from the engine of the aircraft. 5. Floor heating in accordance with claim 4, further comprising: a second bleed air feed line operatively connecting the second hollow chambers to a second supply of hot bleed air from the engine of the aircraft. 6. Floor heating in accordance with claim 5, characterized in that the cross sections of the first and second bleed air feed lines determine the amount of hot engine bleed air supplied. 7. Floor heating in accordance with claim 1, characterized in that the panels are thermally uncoupled from a structure which supports the floor. 8. Floor heating in accordance with claim 1, further comprising: electric heating mats for supplementary heating of the panels. 9. Floor heating in accordance with claim 8, characterized in that the electric heating mats are positioned on the lower side of the panels. 10. Floor heating in accordance with claim 1, further comprising: electric heating coils or wires integrated into the first hollow chambers for supplying supplementary heating therein. 11. Floor heating in accordance with claim 1, further comprising: ventilators positioned in the first hollow chambers to generate a forced flow through the first hollow chambers. 12. Floor heating in accordance with claim 1, further comprising: thermal insulation located on a lower side of the panels. 13. Floor heating in accordance with claim 1, characterized in that the panels are profile elements produced by continuous extrusion. 14. Floor heating in accordance with claim 1, wherein the floor of the cabin section is flat and substantially horizontal. 15. Method for heating the floor of an aircraft having a forward cockpit section and a cabin section located aft of the cockpit section and extending along the length of the aircraft, the cockpit section including a cockpit and an avionics bay containing electronic equipment, wherein the aircraft includes a cargo door formed with panels, the method comprising: conveying air over the electronic equipment in the avionics bay to cool the electronic equipment and to warm the conveyed air, thereby to form warm waste air; conveying the warm waste air aftwardly from the cockpit section to a plurality of first hollow chambers that reside below a floor of the cabin section, the first hollow chambers having first ends in fluid communication with the cockpit section and second ends located aft of the first ends thereby to heat the floor of the cabin section maintaining fluid isolation between the warm waste air conveyed in the first hollow chambers and the cabin section of the aircraft between the first ends and the second ends of the first hollow chambers; conveying the warm waste air, after having flowed though the first hollow chambers, through a plurality of second hollow chambers defined by the panels in the cargo door; and venting, via the second hollow chambers, the warm waste air to one of (a) the cabin section and (b) the outside of the aircraft. 16. Method in accordance with claim 15, characterized in that the warm waste air is conveyed through the first hollow chambers in the longitudinal direction of the aircraft and counter to the flight direction. 17. Method in accordance with claim 15, further comprising: conveying the warm waste air into the cabin section after having flowed through the panels of the cargo door. 18. Method in accordance with claim 15, further comprising: mixing hot bleed air from the engine with the warm waste air thereby to create a mixture, the mixture being conveyed to the first hollow chambers. 19. Method in accordance with claim 15, further comprising: mixing hot bleed air from the engine with the warm waste air thereby to create a first mixture, the first mixture being conveyed to the first ends of the first hollow chambers, and thereafter, downstream of the first hollow chambers, mixing additional hot bleed air from the engine with the first mixture to create a second mixture, the second mixture being conveyed to the second hollow chambers in the panels of the cargo door. 20. Method in accordance with claim 15, characterized in that the floor of the cabin section is additionally heated by electricity. 21. Method in accordance with claim 15, characterized in that a forced flow is generated in the first hollow chambers. 22. Method in accordance with claim 15, wherein the floor of the cabin section is flat and substantially horizontal.
