Jet fuel, Aviation Turbine Fuel (ATF), or Avtur is a type of fuel designed for use in aircraft powered by gas-turbine engines. It is clear to straw-coloured 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.
Aviation Fuel or Jet fuel is a mixture of a large number of different hydrocarbons. Kerosene-type jet fuel (including Jet A and Jet A-1) has a carbon number distribution between about 8 and 16 carbon numbers (carbon atoms per molecule); wide-cut or naphtha-type jet fuel (including Jet B), between about 5 and 15 carbon numbers.
Aviation fuel or Jet Fuel is a specialized type of petroleum-based fuel used to power aircraft; it is generally of a higher quality than fuels used in less critical applications such as heating or road transport, and often contains additives to reduce the risk of icing or explosion due to high temperatures, amongst other properties.
Civil Jet Fuels
Aviation turbine fuels are used for powering jet and turbo-prop engined aircraft and is 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 is a kerosene grade of fuel suitable for most turbine engine aircraft. It is produced to a stringent internationally agreed standard, has a flash point above 38°C (100°F) and a freeze point maximum of -47°C. It is widely available outside the U.S.A. Jet A-1 meets the requirements of British specification DEF STAN 91–91 (Jet A-1), (formerly DERD 2494 (AVTUR)), ASTM specification D1655 (Jet A-1) and IATA Guidance Material (Kerosene Type), NATO Code F-35.
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 (-40°C). It is supplied against the ASTM D1655 (Jet A) specification.
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 3.23.

Military Jet Fuels
Jet-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-PRF-5624S Grade JP-4. JP-4 also meets the requirements of the British Specification DEF STAN 91–88 AVTAG/FSII (formerly DERD 2454), where FSII stands for Fuel Systems Icing Inhibitor. NATO Code F-40.
Jet-5 is a high flash point kerosene meeting the requirements of the U.S. Military Specification MIL-PRF-5624S Grade JP-5. JP-5 also meets the requirements of the British Specification DEF STAN 91–86 AVCAT/FSII (formerly DERD 2452). NATO Code F-44.
Jet-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-T-83188D. JP-8 also meets the requirements of the British Specification DEF STAN 91–87 AVTUR/FSII (formerly DERD 2453). NATO Code F-34.
JP-9is a gas turbine fuel for missiles, specifically the Tomahawk containing the TH-dimer TetraHydroDiMethylCycloPentadiene produced by catalytic hydrogenation of methylpentadiene dimer.
JP-10is a gas turbine fuel for missiles, specifically the ALCM. It contains a mixture of (in decreasing order) endo-tetrahydrodicyclopentadiene, exo-tetrahydrodicyclopentadiene, and adamantane. It is produced by catalytic hydrogenation of dicyclopentadiene. It superseded JP-9 fuel, achieving a lower low-temperature service limit of −65 °F (−54 °C).
JP54 is an abbreviation for “Jet Propulsion, A1, Colonial Grade 54″ During the refining process only 15% of the crude oil is made up of JP54 the rest of the grade is used for different types of plastic.
Developed by JP Morgan, Colonial grade JP54 was replaced by AVGAS also known as AVGAS100LL, it’s the number one low sulphur content kerosene used worldwide. It’s gasoline!
JP54 powers gas turbine aircraft engines. Jet A and A-1 have specifications that can be used in fuel worldwide. Jet B is used in cold weather elements. Commonly a number of different mixtures make up jet fuel and this relates to flash points and how the carbon numbers are distributed.
Actually most jet fuel exported from Russia etc. is “JP54” or “Colonial JP54”. It is similar to “Jet A” except the the Specific Energy is 18.4 mj/kg compared to that of 42.8 mj/kg of “Jet A”.
Also there is a slight difference in additives. The jet fuels come in a number of flavors. There is a 100+ page handbook needed to specify them all. However, all the jet fuels relate to additives to A1, which allows the plane not to leave a white tail in the sky showing where a plane has been.
Jet fuel is kerosene, and not a distillate like Gasoil/ Diesel. In the refinery, it separates above gasoline’s and parafins.
So, no airline will ever purchase “JP54”, there is no trading desk that will trade JP54 and you will find no oil company that sells “JP54”. They will sell Aviation fuel A1 enhanced to a variety of specifications, most usual, the Colonial Grade 54. There is no ticker on the commodity exchanges for “JP54” to allow you to see the market value of the product.
There is no special temperature considerations to consider. Remember that at 40,000 feet it is -46 Centigrade more or less regardless of where you are and the season. The only problem related to temperature is when you fill in a wet, hot climate, the air you take along in the same tanks contains a lot of water that condenses and forms spiking ice crystals that will destroy the jet turbine. The airlines will fix this with additives, usually fatty acids.
Military grade jet fuel is produced by the refineries and delivered directly since they will require special additives.
Jet fuels have a typical boiling range of 150-270°C, (which is somewhere between the boiling ranges of the gasoline and diesel we use in our road vehicles), and typically account for around 10-15% of total refinery production (3000 tonnes per day for a medium to large refinery!)
Methodology for Platts Jet Fuel price index
Platts Jet Fuel Price Index is calculated by Platts using that organization’s proprietary daily assessments for Jet Fuel spot prices in the relevant regional centers. When a market is not assessed on a particular day, for instance because of a market holiday, the previous working day’s spot assessment is used. Each of the individual Platts assessments is given a weighting by Platts in the regional baskets, based primarily on uplift data and trading volume; in a similar way, each of the regional indices is given a weighting in the Global Composite Index (speci????ed in the column “Share in Composite Index”).
These values are compared with the average spot prices in 2000, similarly weighted by uplift during that period, to generate a percentage figure reflecting the overall rise in markets compared to the base period. As an example, an index value of 200 reflects a doubling of price since the year 2000.
