- A pitch control unit is a device used in aircraft propellers to control the pitch of the blades. It interfaces with the propeller and is commanded electrically by the Propeller Electronic Control (PEC) Unit1. Another term for this device is a propeller governor or constant speed unit2. The first units were manufactured in 1929 and included a mechanical hand-driven wheel to change the blade pitch3.Learn more:✕This summary was generated using AI based on multiple online sources.
