3 Navigation: Chart
3-1 Introduction to navigating
The chart window shows the chart, the boat’s position course and navigation data.
The Instrument has two ways of navigating, going straight to a point or following a route.
3-1-1 Navigating to a point
When the Instrument 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 Instrument is connected to an autopilot,
the Instrument 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 Instrument has no autopilot, steer the
boat manually:
a use the boat position and destination on
the chart or highway windows
b or use navigation data displayed on the
data header (see section 2-7-3)
c or use COG and BRG on the compass (see
section 2-7-4).
Note:
1 If the XTE alarm is enabled, an alarm will
sound if the boat deviates too much from
its intended course (see section 17-8).
2 If the arrival radius alarm is enabled, then
an alarm will sound to show that the boat
has reached the destination
(see section 17-8).
3 When the destination is reached an
arrival warning appears with the option
to cancel navigation (goto or route).
yes
the navigation is cancelled,
no
navigation
continues however XTE and highway are
no longer displayed.
