The issue there is that the AFD is a compilation of information from
different sources, one of which is the FAA.

What are the others?


National Aviation Charting Office
(http://en.wikipedia.org/wiki/Airport/Facility_Directory).
Considering myafd.com has the charts and most of the same information,
yet lacks some non-NACO related information suggests that there are
other sources involved as well,
