Mass balancing of ailerons may be common, but it is far from universal. The majority of the Aeroncas and T-carts and high-wing Pipers that are such a large part of the GA fleet do not have aileron mass balancing. Since mass balancing will often triple the mass of the surface to which it is applied, it can have a serious effect on performance and useful load. Furthermore, even many fast (200 mph or so) airplanes that do have mass-balanced ailerons are not 100% mass balanced. This category includes Vans RV-series airplanes. Thanks, Bob K. Fair comments.... some aircraft use fractional balancing - in the 1/2 to 2/3 region as a weight-saving measure. A hinge line aft of the aileron leading edge is another tactic. Brian W |
