shown against the selected sensor source
are applied. If manual data is entered the
COG readout shown in the Indicator Display
is displayed in yellowish-orange and the
ship's course vector line is displayed in the
same colour.
If your SOG goes below 0.5 knots the COG
value will show as a series of green dashes.
The COG will return to display an active
course bearing when SOG is at 0.5 knots or
higher.
SOG Source Values
The SOG folder lists the available SOG sensor
data sources with the currently active sensor
source and its value in highlight.
When Computed is selected for the sensor
data source for SOG the system continually
computes the values based on other active
types of sensor data received.
To change the SOG sensor source or values do the following:
1. Tick the button next to the source. Whenever the sensor source is
about to be changed a window prompts to confirm the change.
2. To confirm click the Yes button, or to return to the previous sensor
source and value click the No button.
If no sensor source is available manual sensor data can be entered.
CAUTION: MANUAL SENSOR DATA
Using manual data is not the normal mode of operation. A sensor
device should be selected as soon as valid data is available.
Manual data cannot be entered if AIS input is enabled. Before
entering data turn off the AIS input, see AIS Display in Chapter 10
