Claim 0:
1. A control system for an engine operatively coupled with a propeller, the control system comprising:
an electric propeller governor having a motor and a flyweight governor spring mechanically coupled with the motor;
a sensor operable to sense a propeller speed of the propeller;
one or more control devices communicatively coupled with the motor of the propeller governor and the sensor, the one more control devices configured to:
receive, from the sensor, data indicative of the propeller speed of the propeller;
receive a commanded power level;
energize the motor of the electric propeller governor to provide a first preload on the flyweight governor spring as a result of receiving a commanded power level;
determine whether the propeller speed exceeds a propeller speed threshold, the propeller speed threshold being different than a propeller speed set point; and
as a result of the propeller speed exceeding a propeller speed threshold, energize the motor of the electric propeller governor to change a preload on the flyweight governor spring from the first preload to a second preload, the first preload corresponding to a first set point of the propeller speed set point and the second preload corresponding to a second set point of the propeller speed set point, wherein the second set point corresponds to the commanded power level.
