A gas generation method and apparatus, capable of use in an aircraft, generates oxygen with at least one On Board Oxygen Generating System (OBOGS) and generates an inert gas with at least one On Board Inert Gas Generating System (OBIGGS) and selectively supplies an auxiliary supply of inert gas utilizing a waste gas output of the at least one OBOGS. The inert gas can include nitrogen. An auxiliary source of oxygen can also be provided. Control valves can be used to selectively supply the waste gas output of the at least one OBOGS to the atmosphere or to...

What is claimed is: 1. A method of generating gases, the method comprising: generating oxygen from a first air stream input with at least one On Board Oxygen Generating System (OBOGS); generating an inert gas from a second air stream input with at least one On Board Inert Gas Generating System (OBIGGS), said first air stream input and said second air stream input having substantially the same ratio of nitrogen to oxygen; and selectively supplying one of a fuel tank or cargo bay with a waste gas output of the at least one OBOGS. 2. The method of claim 1, wherein the at least OBOGS comprises two OBOGSs. 3. The method of claim 1, wherein at least one OBIGGS comprises two OBIGGSs. 4. The method of claim 1, wherein the inert gas comprises nitrogen. 5. The method of claim 1, further comprising providing an auxiliary source of oxygen. 6. The method of claim 5, wherein the auxiliary source of oxygen provides oxygen from at least one tank of compressed oxygen. 7. The method of claim 1, further comprising selectively supplying the waste gas output of said at least one OBOGS to either the atmosphere or to either of two locations. 8. The method of claim 1, further comprising receiving a third air stream at a first temperature and providing said third air stream at a modified temperature as a source for said first and second air streams. 9. The method of claim 1, further comprising receiving a third air stream and providing filtered air with a reduced water content as a source for said first and second air streams. 10. The method of claim 1, further comprising monitoring oxygen content of at least one of the gases. 11. A method of generating gases for use in an aircraft including a passenger compartment, a fuel tank, and a cargo bay, the method comprising: generating oxygen from a first air inlet with at least one On Board Oxygen Generating System (OBOGS) and supplying the oxygen to the passenger compartment of the aircraft; generating an inert gas from a second air inlet with at least one On Board Inert Gas Generating System (OBIGGS) and selectively supplying the inert gas to either the fuel tank or the cargo bay of the aircraft), said first air stream inlet and said second air stream inlet receiving substantially the same ratio of nitrogen to oxygen; and selectively supplying a waste gas output of the at least one OBOGS to one of the either the fuel tank or the cargo bay. 12. The method of claim 11, wherein the at least one OBOGS comprises two OBOGSs. 13. The method of claim 11, where the at least one OBIGGS comprises two OBIGGSs. 14. The method of claim 11, wherein the inert gas comprises nitrogen. 15. The method of claim 11, further comprising selectively providing an auxiliary source of oxygen to the passenger compartment. 16. The method of claim 15, within the auxiliary source of oxygen provides oxygen from at least one tank of compressed oxygen. 17. The method of claim 11, further comprising selectively supplying the waste gas output of the at least one OBOGS to either the atmosphere or to either the fuel tank or the cargo bay. 18. The method of claim 11, further comprising receiving a third air stream at a first temperature and providing said third air stream at a modified temperature as a source for said first and second air inlets. 19. The method of claim 11, further comprising receiving a third air stream and providing filtered air with a reduced water content as a source for said first and second air inlets. 20. The method of claim 11, further comprising monitoring the oxygen content of at least one of the gases. 21. A gas generator system comprising: at least one On Board Oxygen Generating System (OBOGS) arranged to receive a first air stream and generate oxygen therefrom, the OBOGS having an outlet in fluid communication with one of a fuel tank or cargo bay; and at least one On Board Inert Gas Generating System (OBIGGS) arranged to receive a second air stream and generate an inert gas therefrom, said first air stream and said second air stream having substantially the same ratio of nitrogen to oxygen; wherein a waste gas output of said at least one OBOGS is selectively supplied to the fuel tank or cargo bay. 22. The systems of claim 21, wherein said at least one OBOGS comprises two OBOGSs. 23. The system of claim 21, wherein said at least one OBIGGS comprises two OBIGGSs. 24. The system of claim 21, wherein said inert gas comprises nitrogen. 25. The system of claim 21, further comprising an auxiliary source of oxygen. 26. The system of claim 25, wherein said auxiliary source of oxygen comprises at least one tank of compressed oxygen. 27. The system of claim 21, further comprising a first control valve and a second control valve, said first control valve selectively supplying the waste gas output of said at least one OBOGS to either the atmosphere or to said second control valve and said second control valve selectively supplying the waste gas output of said at least one OBOGS to either of two locations. 28. The system of claim 21, further comprising at least one heat exchanger to receive a third air stream at a first temperature to provide said third air stream at a modified temperature as a source for said first and second air streams. 29. The system of claim 21, further comprising at least one filter/water separator to receive a third air stream and to provide filtered air with a reduced water content as a source for said first and second air streams. 30. They system of claim 21, further comprising at least one oxygen monitor. 31. The system of claim 21 wherein the OBIGGS is in fluid communication with one of the fuel tank or cargo bay. 32. A gas generator system for an aircraft including a passenger compartment, a fuel tank, and a cargo bay, the system comprising: at least one On Board Oxygen Generating System (OBOGS) arranged to receive a first air stream input and generate oxygen therefrom and to supply said oxygen to the passenger compartment the OBOGS having an outlet in fluid communication with one of the fuel tank or cargo bay; and at least one On Board Inert Gas Generating System (OBIGGS) arranged to receive a second air stream and generate an inert gas therefrom and to selectively supply said inert gas to the fuel tank or cargo bay, said first air stream derived from said second air stream after said second air stream is conditioned by one or more processes consisting of processes which do not substantially alter the nitrogen to oxygen ratio of said second air stream; wherein a waste gas output of said at least one OBOGS is selectively output to either of the fuel tank or the cargo bay. 33. The system of claim 32, wherein said at least one OBOGS comprises two OBOGSs. 34. The system of claim 32, wherein said at least one OBIGOS comprises two OBIGGSs. 35.
