Jet Fuel A-1


Powering the Aviation Jet Engines


Aviation turbine fuels (ATF), more widely known as jet fuel, are fuels used to power aircraft with gas turbine engines, such as military jet aircraft and civilian passenger aircraft. ATF is produced from crude oil by fractional distillation; it consists of highly refined kerosene.


The most commonly used ATF aviation turbine fuels in commercial aviation are Jet A and Jet A-1, which are produced according to standardized international specifications.
