This study of extreme low temperature C-141, KC-135, and B-52 operational missions indicates that the -58 C freeze point specification for JP-4 fuel is ultra conservative. The study suggests that the freeze point could be increased by at least 12 C with no effect on in-flight performance and that there is a good possibility that commercial, Jet A fuel (-40 C freeze point) would be acceptable for these aircraft. A method of identifying realistic extreme low temperature, in-flight exposure and airplane fuel system response was developed. The ground environmental extremes were not studied and could impact the conclusions.
