ECDIS User Guide Annex A – Static Site
65900012 Annex A-9
Range Limit
The Range Limit is the proximity to the Static Site in
which a target may be set to trusted, and will not
raise CPA/TCPA alerts if the target breaches
CPA/TCPA limits.
The Range Limit can be set in the Trusted Targets
window. The default range limit value is 0 NM, so
that no targets can be accidentally set as trusted
unless the range limit is changed. The maximum
value that is set as a range limit is 40 NM.
If a trusted target is no longer within the defined
range limit, whether by changing position or the
range limit value is reduced, then the target is
automatically removed as a Trusted Target and
must be added again manually as a Trusted Target
if it returns to within the trusted target range limit.
As an ECDIS can only see its own tracked
targets, it may not always be possible to
see all trusted targets that have been
selected on other nodes in a multi node
system, although they will be displayed globally in the Trusted
Target list.
Adding a Trusted Target
Only identified targets within the trusted target range limit are eligible to be
added as a Trusted Target.
A target can be added as a Trusted Target by two methods:
1. Enter the target ID into the input box in the Trusted Targets
window, and select the ' Add Target ' button. The target will be
added to the Trusted Target list.
If 'Add Target' button is used and the target is not eligible to be set
to trusted, a message will be displayed indicating the reason and
the target will not be added.
