I know what AirN@v is! I use it almost very day.
Contrary to what you say, AirN@v IS available on-line, through Airbus World. The AMM, IPC, SRM, etc as well as all manufacturers and OEM data are available there.
Hence my suggestion that you go on-line to try it.
In fact, my present (and previous) company insist that the online data is to be used as the primary source of approved data.
The AirN@v stand alone (accessed via software/database pre-installed on a laptop/desktop PC) is only to be used in the event of a failure to access the online data. This is because the on-line data is the most upto date. It may take several weeks for discs to be received following revisions to the approved data.
