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.
