Further heading alignment adjustment
You should always check the compass alignment after swinging the
compass. However, once the initial deviation correction procedure has
been performed, you can make adjustments to the alignment as often
as you wish, without swinging the compass again.
Although the compass deviation correction procedure removes most
of the alignment error, you will probably be left with small errors (of
the order of a few degrees) that will vary depending on the heading.
Ideally, you should check the heading reading against a number of
known headings, plot a deviation curve, and determine the heading
alignment value that will give the lowest
average
alignment error.
This value can then be entered on the Heading Alignment screen, as
described above.
