What are those speeds, then?
The competitor is clearly designed for Vat = Vref = 140 kts at MLW, to stay inside ICAO category C.
The increased weight A321 went over, but this was culled back with the NEO...
Resulting Vapp is 145 at MLW due the A/THR / handling / wind additive.
I can guess Vf=30 will bring some extra speed over Vref, but is f40 not the standard for the -800?
