11. HOW TO MONITOR ROUTES
11-7
[Back to Track] . This mode creates a track to follow to return to the monitored route
when the vessel goes outside the channel limits.
The mode is automatically selected according to whether a monitored route is active
or not and the amount of off course. Further, if a monitored route is active while follow-
ing the instant track route, the instant track mode can be changed manually.
* An additional instant track route can be joined to the instant track route related to a
monitored route.
The parameters for the instant track (channel limit, turn radius, etc.) can be set on the
[Instant Track] page. See section 21.4.
11.8.1 Safe off track mode
If it becomes necessary to deviate from the
monitored route; for example, to avoid
collision, use the safe off track mode to cre-
ate an instant track to a safe location.
1. Click the [Instant Track] button on the
InstantAccess bar™. The [Instant
Track] pop-up window appears and dis-
plays the message "Please click a des-
tination."
Note 1: If a monitored route is active,
the [Back to Track] mode can also be
selected.
Note 2: If a monitored instant track route is already active, an instant track mode
different from the currently active one can be selected.
2. Click a destination. The location is marked with an orange circle and arrow. The
message "Please click a point to decide an angle." appears in the [Instant Track]
dialog box. The location must be within 50 NM of current position.
