Prof!
I appended a further note via PM.
Moving on... There is a difference between max logistic TOW and max tactical TOW and even MTOW. Imagine wing area 221 sq m, Aspect Ratio 8.1, 842 rpm on a 5.33m dia 8-blade prop. In the same breath imagine 400ktas at 9.5kg/nm. And in the next breath range circles centred on Paris 2400nm/30 tonnes; 3450nm/20 tonnes; 4750nm/ferry. These claims are not simultaneous. For example take 400ktas - that's Mach 1.05 tip speed so shed weight or slow down or take a bigger pinch of salt. [Any resemblance to an A400M claims is purely coincidental]. So if MTOW has gone up, in my day 136500kgf @ 2.25g [127500 @ 2.5g] it is not hurrah but rather because the ship is overweight and a burner.
By the bye the C-17A was projected with a 160000lbf payload [2.25g] and 2400nam at M0.77 cruise with LCN [paved surface] coyly quoted as "better than 49". Try an AUW of 265800kgf at 144psi rigid 53/53/53/70 and flex 52/59/71/95... see what you think.
