6 Adjusting Autopilot Settings
WindTrim (wind response) (unE tC)
Note: Only available if vessel type = 6 (sail boat) on Type 150/150G
or Type 400/400G.
WindTrim (wind response) controls how quickly the autopilot
responds to changes in the wind direction. Higher wind trim settings
will result in a pilot that is more responsive to wind changes.
Cruise speed (CSE SPd)
Set the cruise speed to the boat’s typical cruising speed. If both the
boat’s speed through the water and speed over ground are unavailable
via SeaTalk or NMEA, the autopilot will use this default cruise speed
when computing course changes.
AutoAdapt (AUt AdP)
The AutoAdapt feature allows the autopilot to compensate for
heading errors at higher latitudes, which are caused by the increasing
dip of the earth’s magnetic field. The increased dip has the effect of
amplifying rudder response on northerly headings in the northern
hemisphere, and on southerly headings in the southern hemisphere.
Note: If you set AutoAdapt to 1 or 2, you then need to enter your
current latitude in the next screen (Latitude), so that the autopilot can
provide accurate course keeping by automatically adjusting the
Screen text Options
unE tC Range = 1 to 9
Lower values (1 to 3) = autopilot responds to longer term
wind changes (less pilot activity)
Typical values = 4 to 6
Higher values (7 to 9) = autopilot responds to shorter term
wind changes (more pilot activity)
Screen text Range
CSE SPd 4 to 60 knots
Options
0FF AutoAdapt off
1 AudoAdapt compensation on – Northern hemisphere
2 AutoAdapt compensation on – Southern hemisphere
