The U.S. Air Force has been working toward the approval/certification of alternative (non-petroleum) aviation fuels as a part of the DoD Assured Fuels Initiative. The initial focus of this effort has been a 50/50 blend of Fischer-Tropsch fuel and conventional JP-8 jet fuel. This blend was flown on a B-52 in September and December 2006. As part of this process, the Air Force is developing a new fuel certification process to enable (relatively) rapid approval of fuels from coal, oil shale, and biomass. This effort is being coordinated with alternative fuel approval methods being developed for ASTM, as well as the FAA's Commercial Alternative Aviation Fuel Initiative (CAAFI). Up-to-date results for these efforts will be discussed.
