Description

Jet fuel A*1.

Jet fuel designed for use in aircraft powered by gas-turbine engines. It is clear to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A*1 are produced to a standardized international specification.

Jet fuel is a mixture of a large number of different hydrocarbons. The range of their sizes is restricted by the requirements for the product, for example, the freezing point or smoke point. Kerosene-type jet fuel has a carbon number distribution between about 8 and *6 carbon numbers (carbon atoms per molecule); wide-cut or naphtha-type jet fuel (including Jet B), between about 5 and *5 carbon number.

Jet A*1 is the standard specification fuel used in the rest of the world. Jet A*1 has a flash point higher than *8 °C (**0 °F), with an autoignition temperature of **0 °C (**0 °F).
