I upgraded from my 6010 to a new 6030 and went looking for
airspace files. All the sites I found don't include Class E associated with
airports (Airspace we FAR 103 pilots can't fly in (without permission)). I wrote
John Leibacher and asked if was possible to generate a second set of files that
included Class E associated with airports. He contacted Lynn Alley who generated
the appropriate files and put them on his website
http://www.soaringdata.info/.

The FAA has marked the Class E as "Beta - not for navigation" but in my opinion
it is better than nothing.
