Examples of rotor speed reduction using a feed-forward rotor speed control command are provided. In one example, a computer-implemented method includes: receiving, by a processing device, flight command indicative of a change in a flight characteristic of an aircraft comprising a rotor; generating, by the processing device, a change in load factor based on the flight command; generating, by the processing device, a change in rotor speed based on the change in load factor; generating, by the processing device, a rotor speed command based on the change in rotor speed to a flight controller to cause the aircraft to change a rotor speed of the rotor; and changing, by the processing device, the rotor speed of the rotor responsive to the rotor speed command.
