Differences between Jet A and Jet A-1
Jet A specification fuel has been used in the United
States since the 1950s and is only available in the
United States, whereas Jet A-1 is the standard
specification fuel used in the rest of the world. Both
Jet A and Jet A-1 have a relatively high
flash point of 38 °C (100 °F), with an of 210 °C
(410 °F). This means that the fuel is safer to handle
than traditional avgas.
The primary differences between Jet A and Jet A-1 are
the higher freezing point of Jet A (−40 °C vs −47 °C for
Jet A-1), and the mandatory requirement for the addition
of an anti-static additive to Jet A-1.
Like Jet A-1, Jet A can be identified in trucks and
storage facilities by the
UN number 1863
Hazardous Material placards.
Jet A trucks, storage tanks, and pipes that carry Jet A
are marked with a black sticker with a white "Jet A"
written over it, next to another black stripe.
The annual U.S. usage of jet fuel was 20.2 billion
gallons (77 billion litres) in 2009.
Typical physical properties for Jet A and Jet A-1
Jet A-1 Fuel must meet the specification for DEF STAN
91-91 (Jet A-1), ASTM specification D1655 (Jet A-1) and
IATA Guidance Material (Kerosine Type), NATO Code F-35.
Jet A Fuel must reach ASTM specification D1655 (Jet
