...was it possible to be in a position where trip fuel, fuel to an alternate etc was less than the fuel required for CofG movement after take off?...
No, at least it should not have been!
I've read in this thread that fuel was transferred at various times to change COG due to changes in the centre of lift(?). The one I had not considered was the change in lift that occurred in ground effect due to the trailing edge of the wing being so much closer to the ground than the leading edge (is that right?)
I believe I heard that fuel was transferred during landing to partially counter this effect.
So my question is: Would it have been possible to land the Concorde with near zero fuel?
And a supplementary (
) Would it change the handling characteristics, and did this affect fuel calculations at all?
