Description
CIVIL JET FUELS
Aviation turbine fuels are used for powering jet and turbo-prop
engined aircraft and are not to be confused with Avgas. Outside
former communist areas, there are currently two main grades of
turbine fuel in use in civil commercial aviation : Jet A*1 and Jet
A, both are kerosene type fuels.
There is another grade of jet fuel, Jet B which is a wide cut
kerosene (a blend of gasoline and kerosene) but it is rarely used
except in very cold climates.
JET A*1
Jet A*1 is a kerosene grade of fuel suitable for most turbine
engined aircraft. It is produced to a stringent internationally
agreed standard, has a flash point above *8°C (**0°F) and a freeze
point maximum of **7°C. It is widely available outside the U.S.A.
Jet A*1 meets the requirements of British specification DEF STAN
****1 (Jet A*1), (formerly DERD ***4 (AVTUR)), ASTM specification
D***5 (Jet A*1) and IATA Guidance Material (Kerosine Type), NATO
Code F**5.
JET A
Jet A is a similar kerosene type of fuel, produced to an ASTM
specification and normally only available in the U.S.A. It has the
same flash point as Jet A*1 but a higher freeze point maximum
(**0°C). It is supplied against the ASTM D***5 (Jet A)
specification.
JET B
Jet B is a distillate covering the naphtha and kerosene fractions.
It can be used as an alternative to Jet A*1 but because it is more
difficult to handle (higher flammability), there is only
significant demand in very cold climates where its better cold
weather performance is important. In Canada it is supplied against
the Canadian Specification CAN/CGSB 3.*3
MILITARY
JP*4
JP*4 is the military equivalent of Jet B with the addition of
corrosion inhibitor and anti-icing additives; it meets the
requirements of the U.S. Military Specification MIL-DTL****4U Grade
JP*4. (As of Jan 5, ***4, JP*4 and 5 meet the same US Military
Specification). JP*4 also meets the requirements of the British
Specification DEF STAN ****8 AVTAG/FSII (formerly DERD ***4), where
FSII stands for Fuel Systems Icing Inhibitor. NATO Code F**0.
JP*5
JP*5 is a high flash point kerosene meeting the requirements of the
U.S. Military Specification MIL-DTL****4U Grade JP*5 (as of Jan 5,
***4, JP*4 and 5 meet the same US Military Specification). JP*5
also meets the requirements of the British Specification DEF STAN
****6 AVCAT/FSII (formerly DERD ***2). NATO Code F**4.
JP*8
JP*8 is the military equivalent of Jet A*1 with the addition of
corrosion inhibitor and anti-icing additives; it meets the
requirements of the U.S. Military Specification MIL-DTL*****3E.
JP*8 also meets the requirements of the British Specification DEF
STAN ****7 AVTUR/FSII (formerly DERD ***3). NATO Code F**4.
