I scrubbed a flight in a 172 because of a 25 kt wind down the runway. The downwind taxi would have been problematic.
Why?
There's no aileron control when the wind is spanwise.
So no airflow across the wings, ASI zero, glider still airborne?
I believe the EV 97 Euorostar states in the POH that beyond the 10kts DCC, rudder & aileron in-effectiveness could give problems. I know it's a different "certification" issue but you can't change the physics if the testing is reliable.
As an afterthought, it would be more useful if manufacturer's did actually state at what component the aircraft cannot be controlled safely during the landing phase, rather than the "test pilots" findings on a particular day. I'm sure that this figure could be accurately defined using modern aerodynamics software.
