4.12.2 Target Filtering
From the Target List options menu, if 'Show Filter Settings' is selected, a
screen is displayed indicating which filter parameters can be set to reduce the
amount of data displayed on screen. This screen can also be accessed
through
‘System Settings’-> ‘User Settings’ .
Filters can be toggled on and off on the target list by pressing the
‘Options menu’ key and selecting ‘Toggle filters off’ . The bottom line
of the target list shows how many targets are visible or filtered out. If
a filter is set, the filter icon is displayed at the top of the screen.
The Filters icon does not represent CPA/TCPA alarm settings.
4.12.3 CPA/TCPA Settings
The transceiver can be configured to filter out approaching vessels which fall
within certain limits. The Closest Point of Approach (CPA) defines a boundary
around the own vessel upon which, if breached, will trigger the filter. Time to
Closest Point of Approach (TCPA) can only be set if CPA is set, and will trigger
the filter if the time to the CPA limit is breached.
These parameters are set on the
‘Filtering and CPA/TCPA Settings’ menu.
The target list shows targets which trigger the TCPA/CPA filter red.
These CPA/TCPA figures are calculated solely on AIS data and should not be
used for anti-collision purposes.
Note: Setting the CPA/TCPA filter will not activate the Filters Icon.
4.12.4 Target Plot
The Target Plot screen shows the location of other AIS equipped vessels and
shore stations relative to your own vessel. The target plot screen provides a
basic overview of AIS targets and should not be regarded as a substitute for
