When a MOB event has been activated, the Man Overboard window
displays the following read-only data:
•
Bearing (R) - the relative bearing from
CCRP to MOB event.
•
Bearing (T) - the true bearing from
CCRP to MOB event.
•
Range (nm) - the distance from CCRP
to MOB event.
•
Elapsed Time - time since the MOB
event started.
•
Latitude / Longitude - values from
CCRP to MOB event based on Set and
Drift values.
When an MOB operation is active the button at
the bottom of the window displays
Cancel MOB
.
If the MOB event is being activated based on the suspicion that a person
has gone overboard sometime in the past the operator may manually
adjust the elapsed time value accordingly by clicking on the
Manual Edit
button. If you manually edit the
Elapsed Time
value only, then the MOB
symbol is automatically placed at a position based on own ship history
data, with an adjustment based on the Set and Drift value that was in effect
at the manually specified time. The bearing and range values will
automatically update to reflect the new location, which will be along the
own ship history track - offset from the track based on the applied Set and
Drift.
The figure below shows the calculation of position for a MOB event that
occurred in the past along ship's track.
