ABSTRACT:
A helicopter collective control stick having a pilot grip positioned by a linkage assembly whose kinematics permits the control stick to occupy a small envelope and to have the pilot grip motion to be about a large radius. Our collective stick includes a biasing member to balance the control stick and linkage in the mid collective position and which provides a force gradient when the control stick is moved from the mid collective or trimmed position. Further, our collective stick is operable in concert with the full authority side arm controller to operate in either a tracking or a command mode.
