Temporary Route Plans
A temporary route (temp route) can be created
and displayed on screen, either independently, or
in addition to a currently displayed planned route.
The temp route is edited and monitored
independently of the planned route via the Temp
Route tab folder.
The Temp Route tab folder displays off track
limit, speed, turn statistics and waypoint DTG
default values. The speed value is taken from
own ships current SOG and the turn radius is a
system configurable default value.
All temp routes originate from own ship's CCRP
and is shown as a dotted line. A temp route may
be used to join and transition to a previously
planned route.
Creating and Editing a Temporary Route
To create and edit a temp route do the
following:
1. Select Temp Route from the Route menu and click on the
Create/Edit button. A short straight segment starting at the bow of
the ship and in the direction of the ship’s COG is drawn. The
segment is displayed as a magenta dotted line, underneath the
COG dashed line. The length of the line segment represents the
value shown in the Waypoint DTG field (default value 2000
metres). A waypoint circle is drawn at the end of the line segment
and is labelled as
T0 (if Show waypoint labels is ticked in the
Route Display Settings).
2. To add waypoints to the temp route move the cursor into the video
circle, in Temp Route mode the letters TMP WYPT are shown just
beneath the cross hair.
3. Left click at the required position to create the next waypoint. A
waypoint circle is drawn at the selected point and is labelled T1 . A
turn radius representing the value in the Turn Radius field is drawn
between the waypoints. Further waypoints can be created in the
same way.
