I am trying to determine the maximum TO weights of (say) the 737-700 NG. I find the following;-1.The aircraft load manager gives 133000 lbs.2.In the aircraft folder in fs2002 the Aircraft cfg. givesmax.gross wt. 153500.Also in this folder is B737 ref txt -giving max. ramp weight of 153500.(I am not sure if this last file is a PMDG file or was put there by FS Build)3.In the PMDG aircraft operating manual page 9 it gives 1330004. In the above page 12 it has a max. weight of 72000 kgs -about 158000 lbs.Question- which one is correct and if I change the cfg.of the load manager from 133000 to 153500 will it work correctly assuming along runnway such as Heathrow?Any thoughts on this will be much appreciated.David Pedder
