Delivery of high quality fuels to commercial turbine engine aircraft may become more critical for supersonic transport operation. This paper presents high temperature stability test results on current aviation turbine fuel samples taken from refineries and airports throughout the world. Transportation methods involve combinations of tanker, barge, multiproduct pipeline, and truck movements. Data show that, through the application of proper handling techniques, fuels can be transported from refinery to aircraft, through complex distribution systems, with no significant loss in thermal stability. Data also indicate that current aviation turbine fuels are well above the minimum thermal stability specification limits for present subsonic jet aircraft.

To verify the practicality of a single-grade general aviation avgas which would meet the needs of engines using grade 80/87 and 100/130 fuel, a flight evaluation was conducted in selected light aircraft. Some 2200 hr of actual flight operation demonstrated the acceptability of this fuel for grade 80/87 certificated aircraft, together with a performance advantage for grade 100/130 users.

A study has been made by the Coordinating Research Council (CRC) of electrostatic phenomena during the fueling of both a full-scale mockup of a typical jet aircraft wing tank and a small-scale rig representing a single compartment of an integral wing tank. The tests were performed with equipment typical of modern aircraft fueling installations and using several batches of typical aviation turbine fuels as supplied by the manufacturers.
