Classification: CPC B | IPC B

Claim 6:
7. A method for controlling an engine operatively coupled with a propeller, the method comprising:
receiving, by one or more control devices, data indicative of a propeller speed of the propeller;
receiving a commanded power level;
energize a motor of an electric propeller governor to provide a first preload on a flyweight governor spring as a result of receiving a commanded power level;
determining, by the one or more control devices, 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, adjusting the propeller speed set point from a first set point to a second set point to change the propeller speed of the propeller;
wherein adjusting the propeller speed set point based on whether the propeller speed exceeds the propeller speed threshold comprises energizing, by the one or more control devices, the motor mechanically coupled with the flyweight governor spring of the electric propeller governor to change a preload on the flyweight governor spring from the first preload to a second preload, wherein the second preload corresponds to the second set point, and wherein the second set point corresponds to the commanded power level.
