Inconsistencies in contemporary FCOM

Quotes from HN39:
If "alpha-max = alpha (1.06 Vs)" and Vs=Vs1g, how was Vs1g demonstrated in flight test?

It could not have been (in Normal Law), which is inconsistent with the text I quoted. The plot thickens... One possible explanation is that the "Operating Speeds Definition" comes from REV01, whereas the factors you mention are from REV03 in a different volume. All three volumes were issued to us at Blagnac in early January 1988, but we were warned that amendments were already pending.

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)?

Presumably not!
