13. USING TARGETS
To create and use Targets the Chartnav 343 must be
connected to a position-finding instrument such as a GPS or
Decca/Loran and the Chartnav must be receiving a reliable fix.
You may choose to use your Chartnav 343 to steer to a single
point Target or to follow a route, see section 3.
Single Point Route Following
This is where a single point on a chart is chosen and made the
Target.
Multiple Waypoint Route Following
This is where a route on the chart is chosen, a Waypoint is
made the Target and the route is followed in the desired
direction.
The vessel will immediately turn towards the Target
when Navigator Control is engaged. This may be a
large course change!
With Navigator Control selected, engage Navigator Control on
your Autopilot. The vessel will turn onto that track. The Cross
Track Error information will then keep the vessel on course.
As the vessel approaches the Target Waypoint the Waypoint
Arrival Alarm will be triggered.
If the Chartnav is set to Manual Route Following (see section
14.5), when the Waypoint is reached, you have to manually
select the new Target Waypoint. Position the cursor on the
next waypoint and press the
SELECT
key.
If Automatic Route Following has been set, the Chartnav will
automatically move the Target to the next Waypoint in the
route and transmit the new course to your autopilot.
When the Final Waypoint is reached your Autopilot will
continue on its last heading. Regain Manual Control on your
Autopilot.
