Okay, Jim, I think you said an error greater than ten degrees will ground
the airplance. I'll accept that. Can you give me the reference for the ten
degree figure? Are you saying that the airplane should be taken to the
compass rose during the annual or is there some "quick check?"

Part 23 and Part 43.

Runways are to the nearest 5 degrees and will be renumbered
as required. During the annual inspection the compass
should be checked to be sure it is within degrees on all
headings and any time there has been a change in the
airplane that would cause the deviation to change.


Yes, an error greater than 10 degrees, even with the
correction card, requires correction.
