You may choose to upload a file containing turnpoints and
(optionally) tasks that will be merged with FAA airport
information to produce the output. Four different input formats
are supported including SeeYou (.CUP) files, Cambridge (.DAT)
files, and Soaring Turnpoint Exchange (.STX) files as published in
the World Wide Turnpoint
Exchange (WWTX). ILEC .NDB files may also be used as
input turnpoint files, however any airspace they contain will
be lost or overwritten.
Don't have a turnpoint file? See here
for a discussion on where to get one for contest or recreational
Options for controlling the addition of airports in the output
files are as follows:
|Include all other airports within the
||Additional airports are merged with the input turnpoint
list and added to the output files as specified by the
bounding information provided in step #1. If no bounding
information is specified, the output will contain just the
points specified in the input file. Airport
information such as comments, frequencies, and runway data
will be updated.
|Compute a bounding polygon for adding
||A polygon that contains all of the points in the turnpont
file is automatically determined. Airports that fall within
that polygon will be merged into the output files.
|Do not add additional airports to the output
||The output files will contain only airports that were in
the input turnpoint file.
|Format conversion only - don't change
||Only airports in the input turnpoint file will be
included; Airport information such as comments and
frequencies won't be updated. This option is useful
for doing file format conversions.
|Include only points designated as turnpoints
||The output files will contain only designated turnpoints.

You can optionally choose to retain airport names and geographical
coordinates as in the input file, even if those are different from
the official FAA data. You can also choose to append turnpoint numbers
from contest turnpoint files to the turnpoint names so that they
can be easily selected on glide computers in the cockpit.
