JET A-1 is an aviation fuel
formerly known as “kerosene” which
is suitable for most jet aircraft.
It meets stringent international requirements,
particularly those of the latest versions of the
AFQRJOS, the British DEF STAN 91-91 standard,
the ASTM D1655 standard, and the NATO F-35
specification.
It has a minimum flashpoint of 38°C and a
maximum freezing point of -47°C.
JET A-1 is the principal fuel used for jet
turbine engines. It is also used in general
aviation for compatible diesel engine planes.
Jet fuel or aviation turbine fuel (ATF) is a
type of aviation fuel designed for use in
aircraft powered by gas-turbine engines. It is
colourless to straw-colored in appearance. The
most commonly used fuels for commercial aviation
are Jet A and Jet A-1, which are produced to a
standardized international specification. The
only other jet fuel commonly used in civilian
turbine-engine powered aviation is Jet B, which
is used for its enhanced cold-weather
performance.
Jet fuel is a mixture of a large number of
different hydrocarbons. The range of their sizes
(molecular weights or carbon numbers) is
restricted by the requirements for the product,
for example, the freezing point or smoke point.
Kerosene-type jet fuel (including Jet A and Jet
A-1) has a carbon number distribution between
about 8 and 16 (carbon atoms per molecule);
wide-cut or naphtha-type jet fuel (including Jet
B), between about 5 and 15.
