Activated
and Selected When an activated target is selected a
dashed square outline appears centred on
the target origin and information on the
target is shown in the AIS Info window.
When an activated AIS target’s length and
beam exceed the standard AIS symbol
triangle, the AIS triangle is drawn with the
ship’s outline around it. The ships outline
symbol is not displayed if any of the
following apply:
 When the reference point of the
reported position is unavailable.

When the dimensions of the ship are
unavailable.
 When the beam of the outline is less
than 7.5mm.
 When the targets heading is not
reported
When the AIS ship's outline is selected to
display target tote information, the dashed
square outline appears centred on the
target origin and information on the target
is shown in the AIS window.
An AIS ship's outline is NOT
considered for CPA/TCPA
infringements. These calculations will
be taken from the AIS triangle symbol.
Not used in
collision
avoidance The AIS symbol is rendered as a dotted
line with no vector when not used in
collision avoidance calculations when SOG
and/or COG are not available. Or when
the Activate on CPA/TCPA/BCR setting is
disabled in AIS Display.
The default state for a newly acquired target is sleeping.
The following criteria will cause a sleeping target to become activated:

When manually selected by the operator (see below).

When the target infringes the CPA/TCPA/BCR limits shown on the
Target Data tab folder of the Selected Target sub menu.
This is providing the Activate on CPA/TCPA/BCR setting is
enabled in the AIS Display window.
