I can hardly see how it should affect VFR flights.


Well pattern altitudes might be one problem. How about easterly/westerly
odd/even +500 altitudes?

So you're a couple hundred feet off, that's no big deal. As for pattern
altitudes I always use 1000 agl, plus or minus depending on how I round
the field elevation.
