Hi guys,I am currently flying PMDG MD11 between Leipzig in Germany and Hong Kong. Cruising at FL335 (10200m) with M.84. Now suddently by aircraft climbs apx. 3000 feet in a blink of an eye and even after getting down to my cruise alt. I am on the edge of flying too slow and that is with M. 84 which is normally under overspeed.Later I felt some 1000 feet and after getting back on cruise alt. speed was normal.5-10 minutes later I overspeeded with over M 1.0 and the aircraft ended up in some 40.000 feet.The first almost 7 hours went uneventful and I have never experienced anything like this before.Best regardsPeter LundWIN7 + FS9
