Thanks you for your response, will take a closer look at this problem in a few days. I am so happy to have FSX running smoothly and at least one of these two add-ons LevelD or PMDG is working correctly, for this I must thank you and Fsuipc (Wind shift was so UNREALISTIC before FSUIPC 4,2?).I am an MD11 pilot, should I say real? Fsx is a tool in which I use to help make my work understandable, a test bench to test certain things that would normally be impossible to test in real life(e.g. 2 engine out approach, one eng out drift down NATS)and so it has to perform realistically close to perfect. Maybe you'll be hearing from me once Pmdg MD11 is finished. I think that PGDG builds one of the best add-ons but also a very System demanding I also think that if the B747 runs perfectly, all other add-on will also.
Its people like you that make flying fun
TC Thanks
