I have been flying the NGX since the release day and it has been performing flawlessly so far. Yesterday I was carrying out some landing circuits training at LGAV (FlyTampa) and after three consecutive circuits with no flaw at all (two on autoland and one on hand flying), during final approach on fourth circuit, at 400 feet agl, stable on ILS, two A/P engaged, the aircraft had a sudden and fast roll on the right, GPWS started to "scream", both A/P disengaged and the aircraft hit the ground before any manual attempt to recover attitude could be carried out. Weather conditions were pretty fair with light headwind (ASE).Has anyone ever experienced this ? Can it be considered an NGX issue or FSX issue ?Regards

Could it be wake turbulence? ASE does simulate that. Were you near any ai traffic at the time?
