I'm not sure how many others have noticed this or not, but the FAA has started allowing *free* downloads of a lot of their digital products. That includes Sectionals, Aerodrome/Flight Directories, Terminal Area Charts, etc.
FAA Sectionals
VFR Terminal Area Charts
Aerodrome/Flight Directory
Note that each chart is about a 40MB download, so it might take a little while. The A/FD is unfortunately done on a page-by-page basis, so you can't download an entire volume easily. But a clever person could probably figure out a way to write a script to download the individual pages and then join them all into a single PDF.
For anyone looking for a way to make use of this digital data, and who happens to have an iPad lying around, here's another suggestion: Go download an app called Transit Maps. It's a free program designed for reading transit maps for various cities around the world. But a side effect is that it turns out to be an excellent large-image viewer as well. I downloaded a few charts, converted them from TIF to PNG (the developer is looking at adding TIF support but hasn't yet), and transferred them to Transit Maps using a simple http server.
The maps take a second or two to load initially, but once they're in, you can pan, zoom, etc. and it works just like Google Maps, with the center loading first in lower resolution and then higher resolution getting added later. This works becuase Transit Maps processes the raw image to create "tiles" of images that it can load quickly, then go back and get the higher resolution data. It's very usable.
All that's missing is to geo-reference the images, and then put a GPS bug on the screen to track your position. But neither of those tasks is trivial. Viewing a static map, is. With this strapped to your knee, you could toss all of your paper maps.
There may be better applications for viewing these, if anyone has suggestions i'm all ears. But for the price, this is excellent.
