- An engine-driven unit used for variable-pitch propellers. A CSU automatically permits adjustment of the pitch for varying the speed and power. This allows the propeller to operate more efficiently at any selected combination of RPM, manifold absolute pressure, and air speed.Flyweights which are balanced by the oil pressure, increase or decrease the pitch and maintain propeller speed constant.
