Hi,
Then there must be a very narrow %MAC allowed as you approach Max Authorised TO. Wt. Do you have a manual load sheet to look at?
Edit: On L1011 - 50, we obtained a greater Take Off weight by restricting the Zero Fuel Weight, and not allowing the C of G to go too far forward, thus reducing the down elevator force and hence the total bending load on the wing.
