Which ignition system components are used in the Cessna 172 for improved performance?

The Cessna 172 is equipped with two magnetos, which significantly enhance engine performance and reliability. This dual ignition system provides redundancy; if one magneto fails, the engine can still operate on the other magneto. Additionally, having two magnetos allows for better combustion efficiency, as they ignite the fuel-air mixture at slightly different times. This results in a more complete combustion process, improving overall engine performance and providing a smoother operation.

The presence of two magnetos also contributes to a more reliable ignition setup, as both systems can be tested and monitored during pre-flight checks. Pilots can observe the RPM drop when switching from both magnetos to one, ensuring that both units are functioning correctly. This dual setup is a standard feature in many aircraft because it not only enhances performance but also increases safety in case of a malfunction.
