Use COG as heading
If heading data is not available from a compass sensor, it is possible
to use COG from a GPS. COG will be used in the true wind
calculations.
Ú
Note:
The autopilot cannot be operated using COG as the
heading source. COG cannot be calculated when stationary.
Pitch/Roll
If a suitable sensor is fitted, the system will monitor the inclination of
the vessel. The offset value should be entered to adjust the readings
so that while the vessel is stationary at the dock, the
Pitch
and
Roll
value reads 0.
Environment
If a suitable sensor is fitted, the system will monitor the current
sea/air temperature and barometric pressure.
The offset value to be entered should adjust the reading from the
sensor to match a calibrated source.
Rudder
Starts the automatic calibration of the rudder feedback. This
procedure sets the correct relationship between the physical rudder
movement and the rudder angle readout.
Follow the instructions on the display to perform the rudder
feedback calibration procedure.
Advanced
This option is used for manually applying an offset to the displayed
data for third party sensors which cannot be calibrated through the
AP44.
Damping
If data appears erratic or too sensitive, damping may be applied to
make the information appear more stable. With damping set to off,
the data is presented in raw form with no damping applied.
