What is the C172S engine RPM at which it develops 180 horsepower?

The C172S engine develops its maximum rated horsepower of 180 at 2700 RPM. This value is important for pilots and students to understand because it represents the optimal engine speed where the engine operates most efficiently and produces maximum output.

When operating at this RPM, the aircraft can achieve the best performance in terms of climb rate and overall power during flight maneuvers. It is crucial for pilots to be familiar with engine performance characteristics, as they affect flight planning, takeoff and landing distances, and climb performance.

Understanding the engine's relationship between RPM and horsepower also helps with engine management during different phases of flight. While the other RPM values mentioned may correspond to normal operational ranges, they do not produce the same maximum horsepower as 2700 RPM does for the C172S, making it a key figure in the aircraft's performance metrics.
