➤ To follow the reversed route:
3. Press the
GOTO key. The Goto/Follow functions are displayed.
4. Press
FOLLOW ROUTE.
The vessel’s current position becomes the origin and the first waypoint in
the reversed route becomes the target waypoint. The function bar is
removed.
Target Point Arrival
Target alarms (see Chapter 4) can be set up to sound 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.
• The vessel reaches the closest point of approach to the target (ie. it
crosses a line passing through the waypoint and perpendicular to the
track).
➤ To cancel the Arrival alarm and go towards the next waypoint in the
route, press any key.
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.
If the target waypoint was the subject of a
GOTO, or was the last waypoint
in a route, the pop-up alarm is cleared and any temporary waypoint is
removed.
Alter a Route
A route can be followed from a selected waypoint (Join a route) or, if
already following, advanced to the next waypoint. Also the XTE can be
restarted, setting the current vessel position as the new origin.
In addition, a selected waypoint can be moved as described in
Section 3.2, or removed from the route as described in Section 3.3.
