The common use of Jet A or Jet A-1 fuel in aviation turbine engines is due to its specific properties suited for high-performance aircraft. These fuels are kerosene-based and have a high flash point, which enhances safety during handling and storage. Additionally, Jet A and Jet A-1 are formulated to perform well at the high altitudes and low temperatures typically experienced during flight, preventing issues such as fuel freezing or improper combustion.

Jet A and Jet A-1 offer excellent thermal stability, which is crucial for the performance of turbine engines. The fuel's characteristics support efficient combustion, which translates to better engine performance and reliability. This makes it the preferred choice for commercial aviation and many military aircraft.

Gasoline, while used in piston engines, does not have the same performance characteristics or safety profile for turbine engines. Diesel is typically associated with compression-ignition engines rather than the type of combustion occurring in turbine engines. Propellant 83, although known in some specific application areas, is not standard for aviation turbine engines. Consequently, Jet A or Jet A-1 stands out as the optimal and commonly used fuel in this context.
