Main point to make is that, for the conventional AFM (with data to permit unbalancing), any runway redesign for a critical aircraft needs to be looked at in some detail so that one doesn't increase a non-limiting parameter at great expense for little or no gain ... such as instanced above.
Then again, sometimes the operator misses the point anyway. I once did a safety audit on a particular operation and found that the RTOW data for one particular runway was scheduled significantly overweight .. the operator had done the sums on the basis of ASD .. but the limiting case (by a significant margin) was TOD1.
Good to see that Mutt survived Dallas .... best wishes for the Season, my friend ...
