What is Hamilton Standard constant speed propellers?
This propeller system is a double-acting hydraulic propeller system in which the hydraulic pressure (engine oil pressure) on one piston dome is used against governor oil pressure on the other side of the piston. These two opposing hydraulic forces are used to control and change blade angle or pitch.

What happens if Prop governor fails?
Governor Failures—Overspeed Wild changes in prop rpm in flight can signal loss of governing control, forcing the blades into the fine or high-rpm pitch settings. When this happens, get the engine speed down before it does any damage.
What happens when prop governor fails?
What is the most vital component of a propeller governor?
The most powerful force is the governor oil pressure acting on the propeller piston. This piston is connected mechanically to the blades; as the piston moves, the blades are rotated in proportion.
