Additional Detail Information for Turnpoint File
Use
Here are some additional fine points for using input
task/turnpoint files:
- You can choose to limit the output to include turnpoints only.
For tab delmited or .STX input files, "turnpoints" include any
airport marked as a start, finish, or turnpoint.
- For .CUP input files, a turnpoint is indicated in the comment
field, as described in Comments in
CUP and STX files.
- You can choose to retain the names and/or geographical coordinates
of airports listed in input files, even if those names or coordinates
don't match the FAA NASR data. This is useful in contests so you
can be sure the output data matches the input turnpoint file. If the
associated options aren't selected, the official FAA name and/or location
data will replace that given in the input file.
- An option is provided to use the turnpoint number as a prefix
to turnpoint names in the output files. Turnpoint numbers are
taken from the 'NUM' column in STX turnpoint files, or from the
first (index) entry on each line of a DAT file. In CUP and NDB
input files, turnpoint numbers (if any) are assumed to be prefixed
to the name or code.
- Every airport in an input file should have an associated
identifier. If one is not listed as described in Comments
in CUP and STX files the system will search for one in the
FAA database, by geographical proximity. If one is not found,
the airport attribute will be deleted. See Why
are airports sometimes missing in output files? for more
information.
- If a comment in for an airport in an input turnpoint file
begins with an exclamation point, that comment will replace the
auto-generated one in the output file.
- If a comment for an airport in an input turnpoint file ends
with a tilde ('~') followed by additional information, that
information will be appended to the auto-generated comment in
the output file.
