Turnpoint Exchange includes airspace files. The airspace files listed
under Arizona Soaring Association were not provided by ASA, are not
approved by ASA, and are known to not properly depict the location of
the US Mexico border.

In the file asa_2010_sua.sua the border is defined by the Southern
boundary of the following airspace - R2301W, R2301E, Sells 1 MOA, Ruby
1 and Fuzzy MOAs. The border is undefined between W Nogales and
Evelyn. It is then defined by the Southern edge of Tombstone C MOA
and Tombstone B MOA, and is then undefined all the way to El Paso.

A review of the current sectional chart will show that each of these
airspace areas extends to, and it terminated by, the US Mexico border.

The polygon closing line to the South of these airspace areas does not
represent the location of the border.

An airspace file that does properly depict the US Mexico border is
available to ASA contest series and South West Soaring Championship
contestants from the scorer.
