June 16, 201213 yr I have the Wilco Airbus Deluxe Volume 1. I have this issue where I climb on managed mode and everything seems to be going well.I switch from TOGA to CL at 1500' and it maintains 250 below 10K' and accelerates to 280 for climb. On more than one occasion at around 23000' the aircraft just disregards the FD and goes into a steep climb. The FD is attempting to correct this by demanding a downward pitch the but the aircraft/autoflight is just not listening. I have to disengage AP and FD, push the stick full forward to get my pitch down to 5 degrees, I re engage FD and AP and everything is fine, sometimes it happens again and I take the same steps. My GW is around 150K lbs starting my flight with about 24K lbs of fuel. My pitch is 05 down and the weather and there is a cross wind of 26 kts. My target al**ude is 35K. This is pretty annoying and seems very unrealistic. I am wondering if this could this be a bug with the app or can the wind change in FS9 be that significant to throw the aircraft off by that much?????Does flight sim have updrafts? OR is this just something that happens in all aircraft?? I understand that autopilot isn't perfect and might get knocked off now and then but this seems very extreme..
