ABSTRACT:
A foot operated electrical control is disclosed with simulated aircraft rudder pedals coupled to potentiometers for providing signals to a microcomputer having a flight simulation program. The pedals are additionally linked to one another by slides and a rocker arm for simultaneous pedal travel in opposite directions. The potentiometers may provide cumulative signals determined by pedal displacement or distinct signals when functioning independently of one another. For this latter purpose a carrier block for the rocker arm is positionable out of engagement with the foot pedals. Opposed springs of the control serve to position the pedals in an upright static position. Each pedal is coupled to a potentiometer by spring and pedal biased slides with one of the slides in wiping contact with the pedal.
