Certain environmental conditions such as cross-current can cause the autopilot system to steer
persistently to port or starboard, even when the rudder is centered. With a rudder angle reference
sensor / transducer connected to your autopilot system, you can use an autopilot control head
to specify an offset angle in +/- degrees to compensate for inaccurate rudder angle information
caused by such conditions.
The more accurate the rudder angle information, the more accurately the autopilot system can
keep to a correct course.
The rudder angle reference sensor / transducer connection to the ACU connection panel is shown
below.
