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!

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!
