Thanks but I'm looking for Va, the lowest speed at which you can generate the max
allowable (7) g.

Maneuvering speed can be found mathematically. The formula is Vs (stall
speed clean) multiplied by the square root of the g (7). If you put it into
an excel formula it would be Vs*vn where n = acceleration. You can then use
this to build a Vn diagram if you so choose.
Good luck!

Please also keep in mind that stall speed (at least in USA aircraft) is
calculated based on MTOW and farthest allowable aft CG. If you are flying at
weights below MTOW the Va will also be lower as it decreases as weight
decreases (rule of thumb is 1 knot per 100 lbs).
Again you can calculate this using the same formula if you know the lower Vs
or if Vs is unknown for the reduced weight you can calculate using
Va would be the maneuvering speed you previously calculated based on MTOW.
W2 is the current weight and W1 is the MTOW.
Cheers!
