How much horsepower does the C172S engine develop and at what RPM?

The Cessna 172S is equipped with a Lycoming IO-360-L2A engine, which develops a maximum of 180 horsepower at 2700 RPM. This specification is critical as it defines the performance characteristics of the aircraft, including its climb rate, cruise speed, and overall efficiency during flight.

Understanding the power output and RPM is essential for pilots because it affects how the aircraft responds under different flight conditions. The 2700 RPM setting allows the engine to operate at optimal efficiency while providing sufficient power for takeoff, climb, and cruise phases of flight. The performance of the aircraft hinges on maintaining the engine within the recommended RPM range to prevent strain and ensure the longevity of the engine components.

The focus on these ratings helps pilots make informed decisions about power management during various flight operations, ensuring safety and effective handling of the aircraft.
