I have the Wilco Airbus Deluxe Volume 1 on FS9. 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 the aircraft just disregards the FD and starts climbing up to 20+ degrees. The FD is attempting to correct this by demanding a downward pitch the but the aircraft/autoflight is just not listening, it's like the aircraft just wants to keep pitching up! I have to disengage AP and FD, keep downward pressure on the stick and re engage FD and AP and hope it listens which it usually does until it possibly happens again, 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. It also happens when weather is cleared.
One thing that concerns me is that my CL power (EPR, N1) is set too low. I have been over this with various people about the flex temp affecting CL power but if it's only for Flex take off then HOW is CL thrust calculated????
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..
