3 Navigation: Chart
3-1 Introduction to navigating
The Explorer 660 has two ways of navigating,
going straight to a point or following a route.
Enter waypoints at points of interest before
starting to navigate (see section 5-2-1).
Tip: Create a waypoint at the start of the trip
to navigate back to.
Goto: Going straight to a point
The Explorer 660 can navigate straight to a
waypoint or to any arbitrary point:
1 Switch to the chart display
(see section 2-6).
2 Start navigating using the GOTO/AUTO key
(see section 3-4).
When the Explorer 660 is navigating, the
chart, data and highway displays show
navigation data. The chart shows:
The boat position .
The destination point marked with
a circle.
The boat’s plotted course to the
destination.
Two CDI lines, parallel to the boat’s
plotted course (see Appendix C, CDI).
If the Explorer 660 is connected to an
autopilot, the Explorer 660 will send data
to the autopilot to steer the boat to the
destination. Start the autopilot.
If the XTE alarm is enabled, an alarm will
sound if the boat deviates too much from its
intended course (to set the XTE alarm, see
section 15-8).
3 If the arrival radius alarm is enabled, then,
when the boat comes within the arrival
radius of the destination, an alarm will sound
to show that the boat has reached the
destination (to set the arrival radius alarm, see
section 15-8).
4 To stop the Goto, see section 3-4.
Following a route
A route is a list of waypoints that the boat can
follow (see section 6).
1 To create waypoints before creating the
route, see section 5-2-1.
2 To create a route, see section 6-2-1.
3 To start the route, see sections 3-4 or 6-3-1.
When the Explorer 660 is navigating,the
chart, data and highway displays show
navigation data. The chart shows:
The boat position .
The waypoint at the end of the current
leg marked with a circle.
The boat’s plotted course along the leg.
Two CDI lines, parallel to the boat’s
plotted course (see Appendix C, CDI).
If the Explorer 660 is connected to an
autopilot, the Explorer 660 will send data
to the autopilot to steer the boat to the
destination. Start the autopilot.
If the XTE alarm is enabled, an alarm will
sound if the boat deviates too much from its
intended course (see section 15-8).
If the arrival radius alarm is enabled, then,
when the boat comes within the arrival radius
of the waypoint at the end of the current leg,
an alarm will sound (to set the arrival radius
alarm, see section 15-8).
4 The Explorer 660 stops navigating to the
waypoint at the end of the current leg and
starts the next leg of the route:
a When the boat comes within 0.025 nm of
the waypoint.
b Or when the boat passes the waypoint.
c Or if the waypoint is skipped (see section
6-3-2).
5 When the boat has reached the final
waypoint, or to stop the boat following
the route at any time, cancel the route (see
section 6-3-3).
The chart display shows the chart, the boat’s position course and navigation data. To show the Chart
display, press ESC until the chart is displayed.
