<Tr> <Td> </Td> <Td> </Td> </Tr> <P> Jet fuel, aviation turbine fuel (ATF), or avtur, is a type of aviation fuel designed for use in aircraft powered by gas - turbine engines . It is colorless to straw - colored in appearance . 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 commonly used in civilian turbine - engine powered aviation is Jet B, which is used for its enhanced cold - weather performance . </P> <P> Jet fuel is a mixture of a large number of different hydrocarbons . The range of their sizes (molecular weights or carbon numbers) is defined by the requirements for the product, such as the freezing or smoke point . Kerosene - type jet fuel (including Jet A and Jet A-1) has a carbon number distribution between about 8 and 16 (carbon atoms per molecule); wide - cut or naphtha - type jet fuel (including Jet B), between about 5 and 15 . </P> <P> Fuel for piston - engine powered aircraft (usually a high - octane gasoline known as avgas) has a low flash point to improve its ignition characteristics . Turbine engines can operate with a wide range of fuels, and jet - aircraft engines typically use fuels with higher flash points, which are less flammable and therefore safer to transport and handle . </P>
