A method for creating ullage in a fuel tank includes the steps of porting NEA into a mixing chamber during descent, exposing the mixing chamber to ambient air and communicating a mixture of NEA and ambient air into the fuel tank. A complementary apparatus to the method includes a mixing chamber for receiving NEA during descent, a port for communicating ambient air with the mixing chamber during descent and a port for communicating a mixture of the NEA and the ambient to the fuel tank.
I claim: 1. A method for creating ullage in a fuel tank comprising:porting NEA into a mixing chamber during descent,exposing said mixing chamber to ambient air andporting a mixture of NEA and ambient air into said fuel tank;wherein porting said ambient air into said fuel tank includes the steps of:porting said mixture to a wing tank and,porting said mixture from said wing tank to a center tank;the method further comprising:porting said NEA to said center tank if not in descent andporting ullage from said center tank to said wing tank.
