All,

I was once told that instrument procedures (i.e. approaches) are published
in text form, and then rendered into NOS charts (and a similar process for
Jeppesen).

1) Is this true?
2) If so, is this "raw" data available to the public somewhere? I'm
looking
for something similar to the ATA-100 databases which can be purchased from
the FAA.
3) How did NOS wind up producing the charts anyway?

Thanks in advance,
mark


I believe you can download (ftp) the text files from the following web site:
