Change Heading with RCAH
Change Heading While in Autopilot (RCAH)
You can steer to a new heading with the Straight Right Arrow and Straight Left Arrow buttons. Momentary presses of either of these buttons will cause the pilot to alter the heading by one degree per press. For example, pressing the Straight Left Arrow button five times will cause the heading to be changed by 5 degrees to the port. Holding either of these buttons down causes the pilot to turn the rudder so as to make a port or starboard turn. The rudder turns as long as the button is held down or until the rudder reaches the end of its travel range. When you release the button, the autopilot will move the rudder to stop the boat from turning. When the turn is stopped, the autopilot captures the compass heading and then moves the rudder so as to maintain this heading. An example RCAH turn is shown in the figure below.
