Parallel Cursor
The Parallel Cursor facility enables a rotating
parallel cursor centred on own ship’s
CCRP to
be displayed.
The parallel cursor graphics consist of two
dashed orthogonal lines (axes) extending to
the edge of the chart display with their axis
crossing point at CCRP, the end points of each
line are marked with a semi-circular marker at
the edge of the chart display . A series of
equally spaced dashed parallel lines, spaced at
the currently set range ring interval, are shown
on either both sides of the CCRP (full mode) or one side of the CCRP (half
mode).
To access the facility click on the Parallel Cursor field from the NAV Tools
menu list. The Parallel Cursor window is displayed.
To turn on the Parallel Cursor and change settings do the following:
1. To turn the parallel cursor on tick the Display On check box. The
first time the parallel cursor is displayed, one cross axis runs
parallel to ship’s heading and the display mode is in full.
2. When the parallel cursor is displayed the Interval field changes
from Cursor Off to displaying the line interval in nautical miles
(NM). To increase or decrease the NM interval change the scale
ratio.
3. To toggle between Full and Half mode click on the Display Mode
drop down arrow.
