What is the primary effect of the Nf governor in flight operations?

The primary effect of the Nf governor in flight operations is to maintain the propeller RPM within a specified limit, specifically preventing it from exceeding 1853 RPM. This is critical for ensuring the safety and efficiency of the aircraft, as exceeding the maximum RPM can lead to propeller damage or failure. The Nf governor automatically adjusts fuel flow to the engine based on the propeller speed, keeping the RPM stable during various phases of flight, including climbs, descents, and cruise.

Maintaining the RPM within safe operational limits also helps optimize performance and reduces the risk of overspeed situations that can compromise aircraft integrity. This regulation of engine output is essential for reliable flight operations, which is why the specific focus on maintaining the propeller RPM is vital in the context of the Nf governor’s function.
