Path predictor – user selectable to present a path predictor, in
place of a velocity vector, as a curved line originating at CCRP and
extending along the predicted path over ground own ship will
travel in the time interval used for the velocity vector. The path is
drawn as thin long dashed line style with the same basic colour
used for own ship symbols.
Past track - user selectable to present a past track for the primary
and/or secondary positioning sources. The past track is presented
as line connecting own ship current and past positions. The
primary past track shall be drawn using a thick solid line style with
same basic colour used for own ship symbol.
The secondary past track is drawn using a thin solid line style with
the same basic colour used for own ship symbols.
Past track time increments - may be selected and are shown as
short single lines perpendicular to the past track, spaced along
the past track to represent the distance own ship travelled in the
user selected increment of the time interval used for the velocity
vector.
Past track past position markers - may be selected and these
are shown with time markers.
Past positions are drawn as small filled circular symbols with a
diameter of not more than 1.5 mm, with the same basic colour
used for own ship symbols.

Tracked target symbols
Manually marked radar target in acquisition state - targets which are manually
marked for acquiring are shown as thin broken circle, centred at and guided with
the position of target. The circles have about 5 mm in diameter and are drawn
using a thin dashed line style with the same basic colour used for target symbols.
Targets get a number in the sequence of appearing.
Automatically detected radar target in acquisition state – which is detected after
entering a set acquisition zone. It is a circle, nominal 5 mm in diameter and using a
thick dashed line style, with the required colour red.
The symbol flashes until acknowledged by the user. Once acknowledged, the
symbol ceases flashing (even when they remain inside the acquisition area) and
unless considered as dangerous, shall be drawn as a normal radar target in an
acquisition state (i.e. detected outside an acquisition area) with the basic colour of
other non dangerous target symbols. If additional detected as dangerous, it stays
red coloured.
Calculated tracked radar targets - are presented as circles centred at the targets
tracked position. The circles are 3 mm in diameter and be drawn using a thick
solid line style.
Tracked radar targets generated from a target automatically detected in an
acquisition area that have not been acknowledged, are basic coloured in red and
continue to flash until acknowledged by the user (even when they move outside
the acquisition area).
Once acknowledged, the symbols cease flashing and unless considered as
