Jet Fuel / Aviation Kerosene
Jet fuel is aviation fuel designed for use in aircrafts powered by gas-turbine engines.
First of all, there is no aviation fuel in the industry named JP54. No refinery in the world produces JP54 and no airline in the world would buy JP54. The most commonly used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification. The only other jet fuel used in civilian turbine-engine powered aviation is Jet B, which is used only for cold-weather performance but its lighter composition makes it more dangerous to handle and thus rarely used.
Jet A specification fuel has been used in the US since the 1950s and is usually not available outside the United States and a few Canadian airports whereas Jet A-1 is the standard specification fuel used in the rest of the world, The Russian product is called TS-1 and is a common standard.
The major difference in Jet A and Jet A-1 is the lower freezing point of A-1 and the mandatory addition of an anti-static additive to Jet A-1. The corresponding ASTM specification is D1655.
Avgas (Aviation Gasoline) is used in small piston engine aircrafts within the aviation community, mostly airplanes used by private pilots, for flight training, by flying clubs and for crop spraying. There are only two main Avgas grades (100 and 100LL low lead)
Military organizations all over the world use a different classification system starting with JP (for "Jet Propellant"). Jet A-1 is similar to JP-8, Jet B is similar to JP-4. JP-2 and JP-3 are obsolete. Other grades are JPTS, Zip Fuel, Syntroleum, Synthetic Jet Fuel and Jet Biofuel.
