G-PILOT driving rudder to
port, rudder is at 12° to port
G-PILOT is not driving rudder,
rudder is at 18° to port,
If the rudder is turned 30° or more, the display
shows 30° and the arrowhead is on:
G-PILOT is not driving rudder,
rudder is amidships
direction the rudder is moving. For example:
Rudder angle can be displayed even if the boat
is being steered manually.
Course error
The course error is the angle between the
actual boat heading and the intended autopilot
course, for example:
Actual heading 90°
CTS (course to steer) 110°
Course error is 20° to starboard
Actual heading 290°
CTS 250°
Course error is 40° to port, but 30° is
the largest error that can be displayed,
so the display shows 30° to port
