14.11 Using AIS to avoid collisions
You can use the AIS safe zone and safety message functions to
help you avoid collisions with other vessels and objects.
Safe Zones
A safe zone is a ring centred on your vessel within which a target
is considered dangerous. It is displayed in the radar or chart
applications as a red ring.
This AIS safe zone uses the same criteria as MARPA and will
deem a target dangerous if it comes within a specified distance
of your vessel (closest point of approach or CPA) within a
specified time (time to closest point of approach or TCPA). The
CPA and TCPA are calculated using COG/SOG and position
from the AIS target.
When your system recognizes a dangerous AIS target:
• The target symbol changes to red and flashes.
• The dangerous alarm dialog is displayed (this can be disabled
if required).
• The dangerous alarm sounds (this can be disabled if required).
Note: When the AIS unit is connected and functioning, the
system will check for dangerous targets within the safe
zone and if enabled issue an alarm whenever necessary.
Dangerous target alarm operates irrespective of the status of
the AIS target display, or the safe zone ring.
Safety Messages
When the status of the AIS Safety Messages function is set to
On, any incoming safety messages from surrounding vessels,
shore stations and mobile stations are displayed in a dialog box.
If known, the message will include the sending vessel’s position
in latitude / longitude. You will have the option to:
• Remove the message ( Ok ).
• Place a waypoint on your chart / radar to mark the sending
vessel’s position ( Place Waypoint ).
• Goto the sending vessel’s position ( Goto Waypoint ).
Note: You will NOT receive any safety messages in
Simulator mode ( homescreen > Set-up > System Settings
> Simulator ).
