The latter, I think. For example, over the past several years, I've noticed
and reported more than a dozen instances in which airports in the NY
Sectional were displaced by up to a mile or so from their actual locations
(in some cases, they were moved to the wrong side of a river or highway,
which makes it particularly confusing to use the chart to find a given
airport for the first time). The errors were always fixed in the next
edition, but I've never seen such repositionings mentioned in the chart
bulletins.
