(3) CREATE MAP, INDEX LINE
INDEX LINE
Map index lines are shown as relative lines on the PPI. Using a paper chart
they are planned before passing obstacles to maintain stand- off range. They
also used to prepare wheel-over points.
The index lines can be plotted on the Radar video using two points. Index lines
can either be shown as continuous or dotted.
The coordinates of the index lines are ship- specific (relative) and are shown in
(  ) for the bearing and in (NM) for the distance in the EDIT INDEX LINE
display.
