Jet A/ Jet A-1
This kerosene-type jet fuel, is the most commonly consumed jet turbine fuel, used by all commercial airlines around the world. In the U.S. and in some Canadian airports during the summer, Jet A is the standard jet fuel in use. The important difference between Jet A and Jet A-1 is the freeze point (the key low temperature limiting quality): Jet A has a freeze point of -40 °C maximum, whereas Jet A-1 has a freeze point of -47 °C maximum. Jet A-1, with the lower freeze point, is frequently required on high altitude flights when the fuel in the wings may be cooled to a very low temperature. Military aircraft in Canada and the U.S. use a version of Jet A-1 called F-34. This is a kerosene-type jet fuel with a freeze point of -47 °C plus two additives: fuel system icing inhibitor (FSII) and corrosion inhibitor.
Additives Available
Fuel System Icing Inhibitor (FSII)
Ice can form in fuel tanks at very low temperatures encountered by high altitude flying or in cold climates. Ice crystals can form from water that was dissolved into the fuel but seperated from the fuel as the tempurature dropped. Such ice crystals can cause filter plugging. FSII works by merging with any free water thus lowering it's freezing point.
The additive must be added at a controlled rate of .10-.15% into a flowing stream of fuel to ensure that it is completely dissolved in the fuel. The only FSII approved by Canadian and U.S. military is di-ethylene glycol monomethyl ether (di-EGME).
Corrosion Inhibitors (CI)
Jet fuel ditribution systems such as tanks, piplines, as well as some aircraft engine components are constructed of primarily uncoated steel. CI prevents free water and oxygen in the jet fuel from rusting or corroding these structures.
Static Dissipator (SDA)
Refinery processing can remove naturally present polar species generating fuels with poor conductivity. Such fuels have an increased rick of charge generation and ultimatley static discharge during loading or as fuel passes through the filters.To eliminate the risk SDA is added to jet kerosene. Stadis 450 is the only additive currently manufactured for use in aviation turbine fuels. CAN/CGSB-3.24 requires the SDA additive.
