we moved the user manual and airline manual (and some other stuff) to the new FTWiki.
The FTWiki can be found here: https://openair-alliance.eu/ftw/doc
The FTWiki and the manuals are "german only". Please make sure to read the "Translation Howto" and let us know, how it works for you!

Please post any feedback here or send it directly to me!
Cheers,
Markus
