Hello, using XP12 Toliss A320, AIRAC is current.  
The aircraft does not load the nav data (not in data base), although NTTB is present in the CFIP data. Simbrief also displays the data correctly.  
Kind Regards

Most likely the runway is too short in the apt.dat files and it gets filtered out by the ToLiSS plugin.

Regards,

Hi,  
It’s straightforward to check on your own. Select the stock Boeing 737 and check the procedures there. If they are included, you know this is a ToLiss or installation issue on your side.

However, the procedures are included (you confirmed them via the CIFP file), so they should be selectable. Tim’s hint is valid!

Cheers  
Richard

It works with Garmin 430, so it’s probably a Toliss restriction. Although: NTTH has the same RWY length as NTTB and it also works with A319/320 from Toliss. Anyway, thanks for the support

The ToLiSS developer may be able to explain why it’s unavailable and/or fix it, over on the [X-Plane.org](http://X-Plane.org) forum.
