What is a constant speed propeller equipped with?

A constant speed propeller is equipped with a governor, which is a crucial component that automatically adjusts the pitch of the propeller blades to maintain a constant rotational speed of the engine, regardless of changes in engine load or operating conditions. The governor senses the RPM (Revolutions Per Minute) of the propeller and adjusts the blade angle to either increase or decrease the amount of thrust produced, ensuring efficient performance and optimal engine operation.

This automatic adjustment allows pilots to focus on other aspects of flying, as the propeller system maintains engine speed without needing constant manual input. In contrast, other options such as a pilot control only or a fixed pitch blade do not provide the same level of automatic regulation. Additionally, a throttle lever is separate from the propeller control and is used to manage engine power output rather than directly maintaining propeller speed.
