Jet A-1 is a type of aviation fuel, mainly composed of kerosene, tailored for jet and turbo-prop aircraft. Engineered to meet stringent industry standards, Jet A-1 fuel is formulated for stable performance at high altitudes and cold temperatures, with a freeze point around -47°C (-53°F) to prevent freezing in aircraft fuel systems. It also has a low flash point, making it suitable for high-energy applications required in aviation.

The fuel’s reliable combustion properties ensure a consistent supply of energy during flight, and additives may be included to improve storage stability and reduce risks associated with microbial growth in fuel tanks. Used globally, Jet A-1 is the standard fuel for commercial airlines, as well as many cargo and private jets.
