Which type of fuel is commonly used in aviation engines?

The commonly used fuel in aviation engines is jet fuel, which is specifically designed to meet the requirements of turbine engines found in most commercial and military aircraft. Jet fuel is a kerosene-based fuel that has properties optimized for high performance in the demanding operating conditions of aviation, including high altitude and fluctuating temperatures.

Jet fuel provides a high energy-to-weight ratio, which is essential in aviation to maximize the efficiency of flight. It is formulated to have a low freezing point and to prevent the formation of ice in the fuel lines, which is crucial when flying at high altitudes. Additionally, jet fuel’s combustion characteristics are well-suited for the high-load and high-speed environments that turbine engines operate in, contributing to aircraft safety, reliability, and efficiency.

In contrast, gasoline, while used in some smaller general aviation aircraft with piston engines, does not have the appropriate characteristics for turbine engines. Similarly, natural gas and cooking oil are not suitable for aviation applications due to the lack of energy density and other physical properties required for efficient aircraft operation at altitude. Thus, jet fuel stands out as the standard fuel type in the aviation sector.
