Road transportation in the context of "Aviation fuel"

Aviation fuels are either derived from petroleum or are blends of petroleum and synthetic fuels, and are used to power aircraft. These fuels have more stringent requirements than those used for ground-based applications, such as heating or road transportation. They also contain additives designed to enhance or preserve specific properties that are important for performance and handling. Most aviation fuels are kerosene-based—such as JP-8 and Jet A-1—and are used in gas turbine-powered aircraft. Piston-engined aircraft typically use leaded gasoline, while those equipped with diesel engines may use jet fuel (kerosene). As of 2012, all U.S. Air Force aircraft had been certified to operate on a 50-50 blend of kerosene and synthetic fuel derived from coal or natural gas, as part of an initiative to stabilize fuel costs.
