WHAT IS JET A FUEL?
Jet A is a flammable, kerosene-type jet fuel normally only available in the United States. This fuel enjoys massive popularity in American aviation—more than 575 million barrels were produced in 2016 alone. Jet A is notably similar to Jet A-1—a common type of jet fuel in the U.K. and elsewhere around the world—but has a higher maximum freezing point of -40 degrees Celsius. Both Jet A and its international counterpart have a density of 6.71 pounds per gallon.
You’ll recognize Jet A by its pure white or straw white color and its smell, which is similar to that of kerosene. The fuel should be sumped daily to ensure it stays clean, dry and on-color, and maintains a proper odor.
Along with standalone use, Jet A can be blended with Fuel System Icing Inhibitors (FSIIs), such as Di-EGME or PRIST. These FSIIs prevent ice from forming in the fuel lines. You can also buy either traditional Jet A or bio-based jet fuel, which has proven successful in many flights.
