The cross symbol flashes while
the Lost Target alarm is
unacknowledged.
Note that lost AIS targets do not
generate CPA/TCPA alarms.
AIS targets in an Activation Zone will remain flashing red until the AZ Entry
alert is acknowledged (see Alert Status Indicator). When the alert has been
acknowledged the AIS symbol will revert to its normal (green) state, even
when the target remains in the Activation
Zone.
When CPA/TCPA Limit and Bow Crossing Limit alerts have been
acknowledged the AIS symbol stops flashing, but the symbol remains in
red until the CPA/TCPA and Bow Crossing infringement limits no longer
apply.
AIS Safety Messages
Safety messages can be sent from own ship to
selected AIS targets. The safety message is sent
using an AIS minimum Keyboard & Display (MKD)
which can be accessed by either right clicking on the
AIS target, or from the AIS Info tab folder in the
Selected Target sub menu.
For information on using the MKD to send safety messages, see AIS Info.
Two -node Support for AIS Targets
In a two node system, one or more nodes may be responsible for
interfacing with the device that provides AIS target and own ship AIS
data. The system will make one node (with an interface to an AIS device)
responsible for distributing the AIS target and own ship data to all other
nodes.
WARNING!
IF A LOCAL NODE LOOSES COMMUNICATION WITH THE AIS
DISTRIBUTING NODE, ALL AIS TARGETS ARE REMOVED FROM THE
LOCAL NODE DISPLAY.
