Adjusting the heading alignment
After completing the initial compass calibration, you can make further adjustments to the
alignment without having to swing the compass again.
Although the compass calibration removes most of the alignment error, small errors (a few
degrees) will probably remain.
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. You can then enter this value on the Heading Alignment screen, as described
above.
If the average heading error is more than 5°, you should perform the compass deviation
correction procedure again, circling more slowly and in more favorable conditions.
