FH,
Thanks for that .. and what would be a typical CG/IU co-ordinate for the loading when you would consider rearranging the load to move the cg aftwards ?
I don't have any 800 background .. but on the earlier models .. it gets interesting if the cg is aft and the trim set for forward ... the aircraft wants to leap off the ground at an alarmingly low speed .. gets the chaps' (or ladies' or chap's and lady's) attention very quickly ..
