I'd rather stall and recover. I've been trained well to do that. I feel very confident 20 knots above VSO in that airplane, let alone 50 knots above.
My question was, why the relationship between weight and VA is direct? What is there about a heavier plane that makes it withstand higher structure loads?
Or you're saying, since a lighter plane's stalling speed is lower, the engineers thought, let's have them pilots stay further away from structural damage on turns?
