Sorry didn't mean to say it like that, compass deviation
correction. I was thinking about the swinging process,
flying a heading on a cardinal course (government surveyed
roads on sections lines are true N-S-E and W. Variation is
applied when setting the HI to get the local magnetic, then
turns are made with the HI and the compass read to determine
the deviation.

Sorry for being tired when I misspoke.
