I did some test flights with the beta and I find the sudden shifts in wind (or whatever is causing this) that were already present with the real weather in XP12 to be even more violent while using ASXP12. With ASXP12 in the Hotstart CL650 I get frequent altitude deviation alerts because I'm thrown around by at least +/- 300ft in FL390 (but also at lower FL) and V/S shows +/-2000ftmin at times.
