And a question. Why would you have a VA (or whatever you want call it) where you have to check the control input to avoid exceeding "g" limit?
From what I ve learned the last 2 days here, absolutelly nothing.
The only thing that I find helpfull, is that pilots have to be reminded by the presence of Va, that they can only do single full abrupt application of flight controls, below Va
Is anyone aware of an aircraft certified where VA>VS√n?
Yes. The AT3.
Stall speed in CAS (EAS anyway) is 50 knots. In manual, stated Va is 112kts, if you assume standard 4.4G limit. Calculated Vo=104 knots CAS, about 106 IAS
Even worse, AT3 has 3.8G positive load factor limit.
Calculated Vo=97 CAS, about 100 IAS
12 Knots margin!
