US Airspace and Airport Data Update

Updated US airspace information for the charting cycle effective May
5, 2011 is now available on my website at http://www.soaringdata.info;
it should also be available on the Airspace section of the Worldwide
Soaring Turnpoint Exchange soon. Updated US airport data in formats
that support virtually all glide computers and loggers as well as many
recreation-style GPS devices may also be found by following the link
under the Airport Information section on my website.

Please note that the Columbia, SC Class C airspace was erroneously
omitted from the January and March 2011 updates. That error has been
corrected in this revision.

Other stuff on my website includes:

- Current sectional charts in CMR format for SeeYou
- Current sectional charts in TIFF format that can be displayed in
GoogleEarth
- Current airspace maps that can be loaded into Garmin recreational
(non-aviation) GPS receivers

As always, all of this is completely free, and redistributable.

Happy Downloading!
