93% of stock aircraft will still handle poorly on the ground, (AKA 'Why your landings suck - unless you fly a GrandCaravan')

Logically, CFD should help as it - fundementally- more accurately models the effect of relative wind on the aircraft surfaces.

But it’s not this force that seems to be the issue on the ground. It’s the lack of static friction from the tires/contact points and perhaps also inertial forces.

So in some ways CFD could actually make the problem worse - we have one set of forces well modelled and another…absent. It’s not hard then to imagine how aircraft struggle to keep pointing in the right direction (although better modelling of prop wash may increase control surface authority).
