Jet / Aviation Fuel

Jet fuel, also known as aviation turbine fuel or Avtur, is a specialized, refined kerosene-based fuel designed for use in aircraft powered by gas-turbine engines, including commercial and military jets. 

Types and Characteristics:
  • Kerosene-Based:

    Jet fuel is primarily derived from kerosene, a light distillate of petroleum. 

  • Common Types:
    • Jet A and Jet A-1: These are the most common types used in commercial aviation, with Jet A-1 having a slightly lower freezing point, making it suitable for colder climates. 
    • Jet B: Contains a higher concentration of volatile components, making it suitable for cold weather operations, but with a lower flash point than Jet A or Jet A-1. 
    • Sustainable Aviation Fuel (SAF): Emerging as a promising alternative, SAF is manufactured from renewable sources like biomass or synthetic processes, aiming to reduce aviation’s carbon footprint. 
  • Key Properties:
    • Flash Point: Jet fuel has a higher flash point than gasoline, making it safer to handle and store, especially in the event of an accident. 
    • Freezing Point: Jet fuel has a low freezing point, which is crucial for operation in cold temperatures and at high altitudes. 
    • Additives: Jet fuel contains additives to improve performance, such as static dissipaters and gum inhibitors. 
  • Uses:
    • Turbine-Powered Aircraft: Jet fuel is used to power the turbine engines of commercial and military aircraft. 
    • Other Applications: Kerosene, the base of jet fuel, is also used for cooking, heating, and lighting in some regions.
