Updated US Airspace files for the charting cycle effective December
17, 2009 are now available in the airspace area of the Worldwide
Turnpoint exchange. The same files are available on my website
atwww.xmission.com/~lalley/aviation.

My website also includes a file generator for US airport informationin
SeeYou (.cup), Cambridge Aero (.dat) and Nadler database format(.ndb)
for the ILEC SN10. The data source for my file generator has been
updated for the December 17 charting cycle.

Happy downloading!
