Thanks
John, I cancelled the post after finding the following link which only seemed to talk about CoG and fuel loading. I thought I was somewhat out of my depth, not knowing the ins and outs of the swept wing brethren. Thought there may have been parallels when I went on a 744 twelve hour scenic, no freight, no bags, just a full load of pax, had to carry two tons of ballast to keep CoG in place.
