Temporary Routes
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 cross track
distance (XTD) limits for Port and Starboard,
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. A temp route can also 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 an orange 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 chart
window, in Temp Route mode the letters TMP WPT 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.
