Hello I'm facing this problem since few flight basically once I'm near cruise altitude I get an Altimeter disagree alert, fallowed by stall warning and overspeed warning the plane loose control quick and the instrument start to show non sense information like 50000ft speed 144 vertical speed rate 3+ or so. I have few second for manoeuvre before crash on the ground or the plane get destroyed by the overspeed stress.
I tried to set US metric, remove failure but nothing today it happened again and I can't understand why.
one note it start since I used Rex Essential I don't know if it linked to it I've done different many flight with Rex 2.0 no problem
also I'm using P3D but once again is nearly 4 month and no problem at all with the NGX please help!
I manage to ge a screen before it crash
Note speed 460 alt -0400 only the standby instrument shows the the right information I guess
Thanks jivan
