Which type of fuel is used for airplanes?

The most common type of fuel used for airplanes is jet fuel, also known as aviation turbine fuel. Jet fuel is a type of hydrocarbon-based fuel specifically formulated for use in jet engines. It is a highly refined kerosene-type fuel that is produced from crude oil through a process called fractional distillation. Unlike gasoline used in piston-engine vehicles, jet fuel has a higher flash point and a lower freezing point, making it suitable for the extreme conditions encountered during high-altitude flights. Jet fuel is also formulated to provide the necessary lubrication for the fuel system components and to prevent the formation of ice crystals in the fuel lines and tanks at high altitudes.
