Route
The data shown in the Route tab folder is
calculated internally from the monitored route
and is read-only.
A route may be selected with a double mouse
click on the Monitor Route menu.
A summary of the active leg of the monitored
route is also shown on the Route Status popup
window.
To monitor own ship's progress against a route,
the ship's COG must be within 110 degrees
toward the planned track and within 80 degrees
away from the planned track, this is referred to
as the `bearing criteria'. If the ship’s COG
deviates more than the bearing criteria, then
route monitoring will stop.
When a route is loaded for monitoring,
monitoring automatically starts on the leg
closest to the ship that is within the bearing
criteria. If none of the route's legs meet the
criteria, then route monitoring will automatically
start when the ship comes within the monitoring
criteria of a route leg.
In some cases the system may begin
monitoring a leg that is not the closest
leg. This will normally occur when own
ship manoeuvres abruptly toward or
away from the closest leg, so that, temporarily, the bearing criteria
are not met.
During route monitoring, the ship’s cross-track distance from the route is
displayed and whether the ship is to the right or left of the track.
Where monitoring values are not currently valid the field displays a series
of dashes.
