Velocity vectors for targets shall
be selected for display.
Velocity vectors shall be
presented as single lines
originating at the targets’
tracked/reported position and
extending in the direction of
course CTW or COG, as
appropriate, for a length
representing the distance the
target will travel in the time interval
used for own ship’s velocity
vector. Vectors shall be drawn
using a thick short dashed line
style with the same basic color
used for target symbols.
Velocity vectors for dangerous
targets shall be the required red
basic color and shall flash with
their base target symbols until
acknowledged by the user.
Once acknowledged, the symbols
shall cease flashing and unless
considered as dangerous, shall
assume the basic color of other
non-dangerous target symbols.
