Avgas: Keeping Propeller-Driven Planes Soaring

While jet engines have become the dominant force in modern aviation, propeller-driven planes still rely on avgas (aviation gasoline) as their fuel source. Avgas is specifically designed for piston engines and possesses distinct characteristics that set it apart from jet fuel.

Avgas comes in different grades to meet the specific requirements of various aircraft engines. The most commonly used grade is 100LL (low lead), which contains tetraethyl lead as an additive to prevent engine knocking. This grade is widely preferred due to its balance between performance and environmental considerations.

For specialized engine designs, other grades of avgas are available. These include 100/130 and 80/87, denoting octane ratings suitable for specific engine configurations.

The higher octane rating of 100/130 avgas ensures optimal performance for high-compression engines, while the lower octane rating of 80/87 avgas is suitable for low-compression engines.

The importance of avgas in keeping propeller-driven planes soaring cannot be overstated. Unlike jet fuel, avgas has properties that cater specifically to the needs of piston engines. Its formulation takes into account factors such as lubrication requirements, combustion characteristics, and resistance to detonation.

Furthermore, avgas plays a crucial role in maintaining the longevity and efficiency of piston-engine aircraft. The use of appropriate grade and quality avgas ensures proper engine function, reduces wear and tear on critical components, and minimizes the risk of engine failure during flight.
