I made a
Google Earth Plugin version of these charts that can be run from web browser. This is about 2 gigabytes of map tiles.
One big huge mosaic covering entire lower 48 US states (AK and HI coming soon). You can switch between Sectional and Terminal Area charts by checking/unchecking the boxes at the bottom.
The Google Earth Version can be downloaded from this post This version is also in the process of being updated with more current maps, mosaic, etc.
