We know the issue, and we're looking at a way to fix it. It's not overly complicated, but it's something that could place the fault evenly on Laminar and us.
Oh yes...was not only the Avitab, but changed a few more things for VR, and created more problems. I have the next version almost ready, but I struggle to find a day to finish it. I'll try this week to make it happen.
Download and install AVITAB plugin from here http://folko.solhost.org/avitab/AviTab-0.3.16.zip. I was playing to incorporate avitab, but left in the code in without checks for avitab, so you must have it to make the plane work.
I appreciate the fast answer and will give it a try again later. Besides I love the TBM 900. It's worth every cent and imho it stands for a new reference in payware sim aircraft.
Very soon[emoji2400] [emoji16][emoji4] OK, seriously now, 2-3 things remaining to do and probably will be about the same time the next Terrain Radar version is out which will support Avanti. So, I can't give exact date, but won't be long.
