automatic rudder gain
When the h1000 pilot is part of an integrated h1000 system, boat speed data is supplied via the
Speed/Depth Interface unit. This allows the autopilot to automatically ‘learn’ the correct value for
rudder gain by monitoring boat speed and rate of turn. The rate of turn will be approximately 7.5
q
per
second.
If there is no direct speed input or the speed is being set by the manual speed band selections, then the
rudder gain value must be entered manually. Refer to
Manual Rudder Gain
.
checking the automatic rudder gain learning
1. Steer the boat onto a suitable heading and allow time for the boat to settle on this course.
2. Select
Compass Mode
by repeatedly pressing the
MODE
key.
3. Press the
ON
key on any h1000 pilot display or hand-held controller.
4. The autopilot will now steer the boat on the selected heading.
5.
At a speed not exceeding 15 knots
, make at least six large course changes of at least 120
q
, by
multiple presses of the 10
q
course change buttons on any h1000 pilot display or hand-held
controller. This enables the autopilot to learn the rudder gain value.
6. When the autopilot has learnt the rudder gain value, the rate of turn will be approximately 7.5
q
per
second. (To estimate the rate of turn the display is updated every 1 second, therefore the heading
display should jump in 7
q
to 8
q
steps.)
7. Press the red OFF key to disengage the autopilot and return to manual steering.
