Description
JET A-1 is a kerosene-type fuel. It is compatible with most jet aircraft, both civil and military, helicopter turbine engines, turboprops and compression-ignition piston engines.
Like diesel, kerosene is a middle distillate. But it is lighter than diesel while remaining heavier than gasoline. It is the most widely used aviation fuel.
It has a boiling point of 150°C-250°C, a flashpoint over 38.0ºC (100ºF) and a maximum melting point of -47.0ºC and it is colorless to straw-colored in appearance.
This fuel is of sufficient quality to meet strict international standards, such as the latest issues to date of the British standard DEF STAN 91-091, the American standard ASTM D1655 and NATO’s F-35 specification.
