Thanks. I was partial to the Airnav site, since it also gave info on FBO's,
rental cars, nearby restaurants, etc., as well as the charts.

Wasn't too happy with AOPA, since it took too much navigating to get the
charts. Airnav was pretty easy.

Will go to NACO now for the latest.

I suspect the AirNav stuff is identical to the "real" charts, and the
disclaimer is mainly a legal requirement. The same holds true for
other sites such as SkyVector. That way, if you use information from
these sites, and if by unfortunate chance it happens to contain any
kind of error, and you kill yourself in a plane as a result, it's your
fault, not the fault of the sites in question. But in practice, it's
the same information in the same format.

There are times when I think the obsession with using only
"authorized" and "certified" charts is a bit pathological. I can
understand avoiding outdated charts, but when you can get a scan of a
current chart online, where's the risk in using it? Are details on
the charge going to be mystically mutated by the simple act of
scanning them?
