I done a full clean install of win7 over the weekend and FSX SP2 and started installing all my planes again. I came to the 777. Installed the base pack started up FSX then out and installed csu772_1000 and done all the online things i had to do. So its as clean as you can get. Got in the 777 for a flight and still had the same VNAV problems it would not clime and would not even hit 250kts. changed over and used V/S and speed up to 290 @8000 went back to VNAV and all it wanted to do was become a glider again ever so slowy sinking to earth. Is there a way to fix this yet or is it still a bug to be fixed ?
