Aviation fuel is a specialized type of fuel designed for use in aircraft. The most common types are Jet A and Jet A-1, which are kerosene-based fuels used in turbine engines. These fuels are formulated to provide high energy content and stability at various temperatures, ensuring safe and efficient flight operations. Another type of aviation fuel is Avgas, which is used in piston-engine aircraft. Avgas is typically leaded, providing the necessary octane rating for high-performance engines. Both types of aviation fuel undergo rigorous testing to meet safety and performance standards set by organizations like the Federal Aviation Administration (FAA).
