Dangerous AIS target – presented as bigger triangle (5mm base
and 7.5mm height) with thick solid lines, red coloured.
Symbol flashes, until it is acknowledged by user.
As soon as it is not stated as dangerous, it changes to blue, like
normal targets.
Heading lines - may be selected for activated AIS targets and
associated targets, represented by AIS target symbols.
Heading lines originates at the apex of the AIS triangle and
extends not less than 4 mm and at least 4 mm beyond the bow of
the true scaled outline when it is used. They are drawn using a
solid line style with the same basic colour as used for target
symbols.
Heading lines for dangerous AIS targets are flashing with their
base symbol until acknowledged by the user.
Heading lines–turn indicators – user selectable to display turn
indicators for activated AIS targets and associated targets
represented by AIS target symbols.
Turn indicators are shown as a single line extending at least 1 mm
but not more than 2 mm perpendicular to the heading line in the
direction of turn. The indicator is drawn using a thin solid line
style with the same basic colour as used for their target symbols.
Turn indicators for dangerous targets will be red coloured (until
no longer dangerous) and will flash with their symbol until
acknowledged by the user.
Activated AIS targets–true scaled outlines - when own ship is
presented as a true scaled outline, the user may select to add true
scaled outlines to activated AIS target symbols.
True scaled outlines for activated AIS targets are drawn around
the AIS target symbol triangle relative to the targets’ reported
position according to the offsets, beam and length. The outline is
drawn in a thick solid line style. True scaled outlines for activated
AIS targets are drawn with the same basic colour used for target
symbols.
True scaled outlines for individual activated AIS targets shall not
be used, when a target’s heading is not reported or when the
beam of the outline is less than 7.5 mm.
If additional parameters are activated like those for OS, they are added to AIS targets and
shown the same way like for OS.
