Critical Points
The Critical Points tab folder enables you to select
and view position and alert trigger details on
critical points that have been generated in the
Critical Points tab folder of the Edit Route menu.
Routes can be loaded for monitoring and cleared
in the same way as described for the Route tab
folder. When a route is loaded the Route area
shows the name of the monitored route.
No data is displayed when a route is first loaded.
To select the first CP on the route click on the
<
button. The field to the right of the
<
button will
show the abbreviation CP1 (unless the CP label
has been changed from the default, see Edit
Route - Critical Points).
CPs are shown as squares
in Monitor mode. When
CPs are selected from the
tab folder the screen
symbol changes from a square to a
rounded triangle.
When a CP has been selected the folder shows the point's
Latitude/Longitude position, its alert trigger and own ship proximity trigger
(distance or time), the type of alert generated (Alarm or Warning) and any
CP description that has been generated. The bottom of the folder displays
the selected CP DTG and TTG status.
To view position and alert trigger details on further CPs, click on the
>
button. The next CP in the route is selected and its data shown in the
folder.
To centre the screen on the selected Critical Point, click on the Goto
button. Own ship, along with all other chart and target positions, are moved
in accordance.
