WebAt high-altitude, the outside air temperature decreases for constant engine revolutions per minute (rpm) and true airspeed (TAS) causing a decrease in the specific fuel consumption of jet engines. Thus, the pilot is able to fly with optimum cruise speed at high-altitudes with the best fuel economy. WebJPTS is a high thermal stability, high altitude fuel, created specifically for the U-2. JPTS has a lower freeze point, higher viscosity, and higher thermal stability than standard USAF fuels. In 1999, the Air Force spent approximately $11.3 million (equivalent to $20.58 million in 2024 dollars) on fuel for the U-2 aircraft and was looking for a lower-cost alternative.
