Hi Sean,

If you are prepared to spend money, GlobalMapper (http://
www.glbalmapper.com) is the way to go. But it is fairly serious
money. On the free side, FWTools (http://fwtools.maptools.org) does
everything you need and more, but the learning curve is steep. It is
a command-line driven thing.

You should be aware also that it isn't just a simple conversion. The
sectionals and state aero charts are published in Lambert Conformal-
Conic projections. You'll need to learn about about map projection,
color maps, and so forth. Unless you already understand this stuff,
it will take many hours of study and experimentation to get a result.
