Target Point Arrival
You can set up target alarms (see Chapter 4) to alert you when the
vessel is approaching the target point. The arrival alarm is defined as a
circle (not visible on the screen), with a specified radius around the
target.
The alarm is triggered when either of the following conditions is met:
• The distance to the target point is less than that specified for the
Arrival alarm.
• Your vessel reaches the closest point of approach to the target (that
is, it crosses the perpendicular to the track, and through the target).
➤
To cancel the Arrival alarm and go towards the next waypoint in the
route,
either
press any key
or wait for 10 seconds.
The target becomes the origin, the next waypoint becomes the target
point, and the two are connected by a dotted line indicating the current
leg. Any previous route leg is removed from the screen, but waypoints
remain.
Altering the Route
You can use the soft keys to follow a route from a selected waypoint
(Join a route), or if already following, you can advance to the next
waypoint. You can also restart the cross track error, setting the current
vessel position as the new origin.
In addition, you can move a selected waypoint as described in section
3.2, or remove a waypoint from the route as described in section 3.3.
Joining a Route
➤
To start tracking the current route at a selected waypoint:
1. Move the cursor over the required waypoint until the letters WPT and
the waypoint soft keys are displayed.
2. Press the FOLLOW FROM HERE soft key.
Your vessel follows the route, using the selected waypoint as the
target point.
3. To return to the default display, move the cursor away from the
waypoint or press CLEAR.
