3-1 Introduction to navigating
The unit has two ways of navigating, going straight to a
point or following a route.
3-1-1 Navigating to a point
When the unit is navigating to a point, the chart and
highway windows show navigation data:
A The boat position .
B The destination point marked with a circle.
C The boat’s plotted course to the destination.
D Two CDI lines, parallel to the boat’s plotted course,
which indicate the maximum expected deviation
from the plotted course.
For more information, see Appendix C.
If the unit is connected to an autopilot, the unit will send
data to the autopilot to steer the boat to the destination.
Start the autopilot before starting to navigate to the
point.
If the unit has no autopilot, steer the boat manually.
use the boat position and destination on the chart or
•
highway windows;
use navigation data shown on the data header or;
•
use COG and BRG on the compass.
•
Note:
If the XTE alarm is enabled, an alarm will sound if the
•
boat deviates too much from its intended course.
If the arrival radius alarm is enabled, then an alarm
•
will sound to show that the boat has reached the
destination.
When the destination is reached an arrival warning
•
appears with the option to cancel navigation.
3-1-2 Going to a waypoint or to a point on
the chart
A waypoint is a position that you can set on the chart, for
example a fishing spot or a point on a route.
