Aviation Jet Fuel Aâ1: Aviation Jet Fuel is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colorless to strawâcolored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet Aâ1, which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B, which is used for its enhanced cold-weather performance. Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. Aviation Jet Fuel is commonly referred to as JP54. However, this is the wrong terminology as there is no such grade of Jet Fuel. Jet A and Jet Aâ1 are what refineries offer. Aviation Jet fuel Gas is what powers turbine aircraft engines. Worldwide, Jet Fuel is the most used low Sulr content Kerosene. For instance, Colonial JP54 is similar to Jet A except the energy is 18.4 mj/Kg compared to the 42.8 MJ/kg of Jet A. Most importantly there is also a slight difference in additives.
