Man Overboard
The Man Overboard (MOB) function enables management of a MOB
emergency. When MOB is active, a symbol is displayed on the chart
display representing `Oscar' – the person in the water.
A MOB operation may be immediately activated by clicking on
the top-level MOB (Oscar) button, situated below the Safety
check icon. The Oscar button is shown in orange whenever the
MOB event is active.
When there is no active MOB event the button is shown in the
standard background colour.
Upon activating the MOB event a symbol is dropped at own ship's CCRP.
The Oscar button is displayed with an orange background and the Man
Overboard window appears with the bearing, range and elapsed time
values. Elapsed time counts up, while range and bearing values update
automatically based on own ship movements. Oscar will drift from the initial
location based on the own ship set and drift at the time the event started.
CAUTION:
The position and heading data used by the system must be valid
and accurate to use the Man Overboard feature as described
below; otherwise erroneous information can be indicated. If this
is the case alternative methods should be used to assist with
search and rescue of the person who has gone overboard.
A MOB event may also be activated from the Man Overboard window from
the Nav Tools menu and clicking the
Start button on this window.
Unlike clicking the Oscar button on the upper toolbar, accessing
the Man Overboard window does NOT immediately generate a
MOB operation. Therefore the preferred method to start an MOB
event is via the Oscar button below the Safety check icon.
