Plain English Meaning
A jet fuel that is a mix of kerosene and gasoline, used mainly in very cold places because it does not freeze as easily as standard jet fuel.
Full Definition
A turbine engine fuel that is a wide-cut blend of kerosene and gasoline, with a lower flash point and better cold-weather performance than Jet A or Jet A-1. It is used primarily in very cold climates because it remains fluid at extremely low temperatures, but its higher volatility makes it more flammable and harder to handle safely.
