How To Use Instant Track To Return To Or Deviate From Monitored Route; Safe Off Track Mode - Furuno FMD-3200 Operator's Manual

11. HOW TO MONITOR ROUTES
11.7 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.
Neither monitored route nor instant track route active.*
• Both monitored route and instant track route are active.*
• The absolute value of off track is within the channel limit
setting.
• Both monitored route and instant track route active.*
• The absolute value of off track is outside the channel
limit setting.
* 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.
