ABSTRACT:
Automatic trim control for a position stick. Strain gauges are mounted with respect to the position stick so as to generate signals proportional to the force manually exerted upon the control stick. The signals from the strain gauges are used to control trim motors which adjust force exerted by springs on the position stick in opposition to the manual force. The signals from the strain gauges are used to control the trim motors so as to reduce the force of the trim springs opposing the manual force. The trim springs are adjusted to reduce the opposition force to a minimum.
