Maneuvering speed is a structural thing.. and it's a maximun. If you're going to be doing steep turns or anything else that might stress the airframe.. Va is not to be exceeded.
The curious thing about it is, that Va actually increases as the airplane's weight increases. Instinctually, you'd think otherwise, but further thought confirms it. The inertia of more mass, makes drastic directional changes less possible.. ;)
