Yet another source for US Airport Information

Some years ago I wrote a program to extract airport information from
the NASR data published by the FAA's National Flight Data Center.
I've finally gotten around to putting a dumb little website around it,
so that others can use it to build their own database extracts. The
site produces .CUP files (for use in SeeYou) and, optionally, a
companion file containing exactly the same set of airports for use in
a glide computer. Two different companion file formats are
available: .NDB for the ILEC SN10, and CAI .DAT format for use with
Cambridge and others (such as GNII) that use it. I've also provided
"how to" notes on using these data with Volksloggers and Garmin GPS
units.

You may ask what the difference is between this and other sources of
similar data. The main difference is in the comment information
provided for each airport. In the CUP file, I support three different
levels of comment detail. The normal level includes runway length,
width, and surface info; communication frequencies; fuel availability;
and owner/manager contact information for private fields. A higher
level adds to this pretty much everything the FAA knows about the
airport; stuff like obstacles, runway and marking conditions, etc. A
low detail level is provided for memory-limited devices, such as
generic (non-aviation) Garmin GPS units.

Since I own an SN10, I've undertaken some special efforts to make sure
the comments make sense and look good on that platform. On the SN10,
the comments will appear properly divided and centered on five 16-
character lines, matching the screen layout of the instrument.

At the same location you can also download current US airspace
information extracted from NASR data. which is also available at on
the Worldwide Turnpoint Exchange. Additionally, I've made available a
few current-ish sectional charts (those for my local flying area in
the Western US) that have been reprojected for use in SeeYou.

All of this information is from public sources; it is free and freely
redistributable.
