Question

Control of hinge moment parameters is called

• A. aerodynamic efficiency
• B. directional stability
• C. lateral stability
• D. aerodynamic balancing

Hint:

Balancing helps reduce pilot effort and avoid control surface flutter.

Answer 1

The Correct Option is D

In aerospace engineering, the control of hinge moment parameters is referred to as aerodynamic balancing. Hinge moments occur in control surfaces such as elevators, ailerons, and rudders, affecting their effectiveness and control force requirements. To reduce manual control effort and improve control surface effectiveness, aerodynamic balancing techniques are employed. These include using offset hinges, tabs, or shaping control surfaces to manage the aerodynamic forces acting at the hinge lines.
