The Manual Edit function can also be used to enter range and bearing
data, or select a position on the chart, but this should only be done if a
visual sighting allows the operator to improve the accuracy of the indicated
MOB location.
When range and/or bearing values are manually edited the MOB
location will NOT be based on elapsed time and history data. The
range and bearing data will be used instead.
To manually enter the MOB values do the following:
1. From the Man Overboard window, click on the Manual Edit button.
The Bearing, Range and Elapsed Time
values become editable and additional
buttons, Done and Cancel Edit appear.
2. To edit the MOB position, enter values in
the relevant fields and click the Done
button. The MOB symbol is re-drawn at
the revised location.
3. Or, to cancel the edit operation, click the
Cancel Edit button.
It is important to press Done or Cancel Edit after activating the
manual edit function. If the manual values are left in the menu this
will interfere with the immediate activation previously described.
Specifically the elapsed time will not count up until the operator
selects either button. The operator must ensure that the manually
entered values are accurate before selecting Done.
To select an MOB position on the chart do the following:
1. From the Man Overboard window, click on the Select A Position
On Chart button and move the cursor into the chart display. The
button changes to Cancel and the cursor displays the Oscar
symbol below the cross.
2. Click in the display area to position the
MOB event. The MOB symbol is
dropped at the selected position with the
range and bearing from the CCRP to the
Oscar displayed and the Start button at
the bottom of the window active.
Note that the MOB operation is not
active until the Start button is pressed.
