    Abstract: A helicopter programmable collective control system includes a motorized collective control stick 2 used in conjunction with a multi-axis control stick 30, with the multi-axis control stick 30 as the default collective controller. A collective control signal processor reads collective input the pilot is giving through one of the two control sticks 2, 30 and provides a motor drive signal 44 (which is dampened to prevent over control) to position the collective control stick 3. The collective control stick position is used to drive the rotor collective pitch actuators 16.
