Parallel Index Lines
The Parallel Index (PI) Lines facility allows multiple sets of parallel index
lines to be displayed simultaneously. Each set may include up to fifteen
lines. The Parallel Index (PI) Lines facility allows up to fifteen index lines to
be displayed simultaneously. The lines span the entire chart display in both
primary and secondary display modes, irrespective of the scale ratio in use.
Each PI line is defined by the range of its closest point to own ship, its
bearing, line type and which side of the ship the line is on.
To access PI lines left click on the Parallel Index Lines field from the NAV
Tools menu list. The PI Lines window includes the following three tab
folders:
Edit - where all PI line and PI set editing functions are done,
including adding a set or line, copying, deleting or renaming a set
of lines or realigning a line or a set of lines to own ship’s current
heading.
Display - enables selection of one or more PI sets to be displayed
on the screen.
I/O - where import and export of PI Line sets is done.
Dual-node Support
Sets of parallel index lines are saved and retrieved in a database, shared
between both nodes. The set of parallel index lines displayed on a
particular node may be specified independently for each node.
