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. It has a boiling point of 150°C-250°C, a flashpoint over 38.0ºC (100ºF) and a maximum melting point of -47.0ºC.
Aviation fuels fall into two categories: kerosene and aviation gasoline.
Aviation gasoline is similar to motor gasoline. It consists of hydrocarbons and tetra-ethyl lead and has a high octane number. It is very popular for propeller aircraft.
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 is the type of aircraft and its technical characteristics that will determine the aviation fuel you use. Because of the conditions in which they are used, these fuels both comply with particularly stringent international quality requirements.
JET A-1 is marked in airport refueling facilities in white letters against a black background, preceded by two white vertical bars. Similarly, JET-A1 dispenser nozzles are painted black.
