Sorry, I meant to ask "aviation grade" map
software that you can zoom in and out or maybe get a profile view or
3D view etc.

You can lay the sectional images over DEM data for a 3Dish view.
Commercial software like ERDAS Imagine can readily handle this. I know
there's Free software to do it, but I haven't tackled it yet. (Pointers
will be appreciated.)

DEMs can be downloaded/ordered from http://seamless.usgs.gov/

Something I too think would be interesting to try. Something I would
investigate "in my copious spare time".

I've downloaded a good-sized chunk of the western US, but I need to
whack together some stitching software to put all the individual
sections back together into a seamless dataset. See spare time comment
above.
