Separate spring devices are linked to the grip for simulating break-out force and force-deflection characteristics. Each spring device is linked to a damper for damping grip movement in the pitch and roll directions. The spring devices have (1) variable spring pre-load bias thereby enabling adjustments of the breakout forces; and (2) adjustable stick neutral position. Transducers measure grip deflection in roll and pitch for utilization by a computer. | |
