The Merchantman (VC9) - the converted Vanguard - has a device in the struts called STAN. I cannot remember what it stands for, but it gave a (very) rough total weight and c of g. IIRC it was asked its opinion when in a steady taxy. It saved my life once when all the pallet weights were completely wrong (the scales had iced up!).
