What is a function of the governor in helicopter operation?

Fluctuates throttle based on pilot input
Synchronizes rotor blades
Adjusts the throttle as needed
Maintains altitude automatically

The correct answer is: Adjusts the throttle as needed

The role of the governor in helicopter operation centers around its ability to adjust the throttle as needed to maintain a constant engine speed, particularly during varying flight conditions. When changes occur in the load on the rotor system—such as during climbs, descents, or turns—the governor compensates by modulating the fuel flow to the engine. This regulation helps ensure that the rotor RPM remains within the optimal range for safe and efficient flight, thus enhancing overall helicopter performance and stability. This function is critical because maintaining the correct engine speed directly impacts rotor performance, which is essential for safe flight dynamics. The governor operates independently of pilot inputs, making automatic adjustments based on flight conditions rather than pilot commands, which distinguishes it from other potential functions within the helicopter’s control systems.
