Which fuel is used in jet air crafts?

The most widely used fuel in jet aircraft is Jet A-1, which is a high-quality kerosene-based fuel specifically designed for jet engines. It is a refined petroleum product that is similar to gasoline but less volatile and has a higher flash point. Jet A-1 is widely available worldwide and is used by both military and commercial jet aircraft.

Another type of fuel used in jet aircraft is Jet A, which has a slightly different composition but meets similar quality and performance standards. Some newer jet aircraft, such as the Boeing 787 Dreamliner and the Airbus A350 XWB, are also certified to use Sustainable Aviation Fuel (SAF), a blend of traditional jet fuel and renewable feedstocks such as plant oils or algae-derived fuels. SAF offers reduced carbon emissions and improved sustainability.
