Balanced Control Surfaces on Aircraft
The purpose and the value of the balanced control surfaces used on the larger size airships and air planes, are not fully. appreciated by persons unfamiliar with the fundamentals of aerodynamics. The layman casually observing a typical balanced aileron, elevator or rudder, Fig. 1 and 2, and noting the comparatively small portion of it which is located in front of the hinge line or pivot, will naturally think that this is done for appearance rather than for any practical reason.
