----------------------------------------------------------
What does "fractioned" mean?
Does this involve the separation of oxygen from nitrogen by evaporation of liquid air?
If so, is there an air liquifier on board, or do you have to fill a storage tank on the a/c with liquid air before take off?
Supertanker ships use engine exhaust gases for inerting. Many supertankers were lost to explosions before exhaust gas inerting was introduced.
Why can't this method be applied to aircraft (maybe with some special attention to eliminating corrosive products of combustion)?
