Describe the function of a governor in an aircraft engine.

To control the aircraft's altitude and speed

To regulate engine speed by adjusting fuel flow and maintaining RPM

The function of a governor in an aircraft engine is crucial for maintaining the engine's performance by regulating engine speed. It achieves this by adjusting the fuel flow to the engine, thereby controlling the revolutions per minute (RPM). This regulation ensures that the engine operates within its optimal speed range, which is essential for efficient performance, reliability, and safety during flight operations. A governor actively responds to changes in the power demand and environmental conditions by making real-time adjustments to maintain the desired RPM, ensuring smooth operation and preventing potential engine issues related to speed fluctuations.

To monitor engine temperature and pressure

To manage the fuel-air mixture for combustion
