I wouldn't know about that - under the 'contemporary norms' Vsmin would have been equal to Valpha-max.
All the operational speeds have to be referenced to a speed which can be demonstrated by flight test. This speed is VS1g for A320 ...
If "alpha-max = alpha (1.06 Vs)" and Vs=Vs1g, how was Vs1g demonstrated in flight test?
Also, if "alpha-prot >= alpha (1.13 Vs)" and "V2 = 1.2 x 0.94 = 1.13 VS1g", then V2>=V(alpha-prot). So V2 can be equal to V(alpha-prot)?
