14.7 How to Use Instant Track to Return to or Deviate
from Monitored Route
The instant track feature provides a temporary track, consisting of four waypoints, to
return to or deviate from the monitored route. Correct data from navigation sensors is
essential to this function.
There are two instant track modes: [Safe Off Track] and [Back to Track].
[Safe Off Track]: This mode provides a track from the monitored route to a safe loca-
tion to avoid collision or the like.
[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 continuously be created and monitored while
monitoring the instant track route.
The parameters for the track (channel limit, turn radius, etc.) can be set on the [Instant
Track] page. See section 21.2.
14.7.1 Safe off track mode
If it becomes necessary to deviate from the monitored route; for example, to avoid col-
lision, use the [Safe Off Track] mode to create an instant track to a safe location. An
instant track can be created without a monitored route.
1. When the monitored route is active,
click the [Instant Track] button on the
InstantAccess bar to show the [Instant
Track] dialog box. The message
"Please click a destination." appears on
the [Planning] page.
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.
