Selecting
Record Track
allows you to define how your course is saved.
Choosing not to save your track may free the processor up to run
other functions a little bit faster; however, you are not likely to notice
any difference in performance unless the four data ports are near their
full throughput capacity. You also have three different levels of track
saving capability:
Normal
,
Fine
, and
Detailed
. The software saves
each calculated position coordinate to draw the lines for the plot screen.
There are a finite number of plot points which can saved in memory,
before the CDU begins overwriting the first set of plot points. If you
are traveling a long distance at a high rate of speed (say over 10 knots)
you probably will want to use the
Normal
selection, which only stores
a plot point when your direction changes. If you are doing some tight
maneuvering or station keeping tasks, you will probably want to use
the
Detailed
selection, which stores a position every 0.5 meters. The
Fine
selection stores a plot point every 7 meters.
