8. HOW TO CONTROL CHART OBJECTS
8-6
[True outlines shown if]: If the length or width of the own ship mark is greater than 3
mm, the own ship mark is shown with the true scale symbol. Select [Length] or [Beam
width].
The right illustration in the figure below shows own ship mark and AIS targets with
scaled symbols. The left illustrations shows own ship mark and AIS targets with point
symbol. AIS targets are displayed as true scale symbol if the displayed chart scale is
larger than set with "Outlines" limit (length>3 mm) on the [General] page in the [Sym-
bol Display] menu and your own ship are displayed as true symbol scale if the size of
the true scale symbol is larger than 3 mm on the chart display.
[Velocity Vectors]
[Ship Vectors]: Show or hide own ship vector.
[Target Vectors]: Show or hide target vectors.
[Style]: Select the vector style. The [std ECDIS] vector is a speed-referenced vector
symbol. [Conventional] is a simplified symbol.
[Time Increments]: Check to show ticks of velocity vector. This controls both own ship
and targets ticks. If ticks are too tightly spaced, they will be automatically removed
from the display, until spacing between ticks is sufficient to distinguish them separate-
ly. This depends on display scale and speed of vessel and target.
[Path Predictor]: Check to show the path predictor. The path predictor is a single
dashed line originating at the CCRP and drawn at a length to represent the distance
and path own ship will travel over the ground in the user-selected time interval for own
ship speed vector.
[Radar Antenna]: Check to mark position of radar antenna (with "x”).
