Abstract
The rudder angle indicator system utilizes a low cost potentiometer coupled to the rudder to provide a signal proportional to rudder angle. A stepper motor positions, in open loop arrangement, the dial of a rudder angle indicator, such as a large three-faced rudder angle display, in accordance with the potentiometer signal. An active sector tab and sensor are utilized to provide a signal in accordance with when the indicator is in the active sector of the display so as to minimize the search for the indicator zero index tab.
