Which of the following represents all types of aerodynamic balances?

The answer is focused on specific components that help achieve aerodynamic balance in an aircraft. Horn balance, balance tab, and internal balance are terms that refer to different methods and mechanisms used to control the stability and control of an aircraft.

A horn balance is a type of control surface design that reduces the control forces needed to move a control surface, enhancing responsiveness and reducing pilot workload. Balance tabs are small surfaces attached to a control surface that move in opposition to the control surface itself. This reduces the force required to move the primary control surface, helping to create a feeling of balance during flight. Internal balance refers to methods implemented within the aircraft structure itself to achieve a neutral stability, ensuring that the aircraft maintains its intended flight path without excessive pilot input.

The other options highlight concepts that relate to aerodynamics and control, but they do not comprehensively encompass the mechanisms used for establishing aerodynamic balance. While the center of gravity and control surfaces are certainly essential for aircraft performance, they don't represent the detailed mechanisms. Static and dynamic balance are more general terms pertaining to weight distribution and forces rather than specific aerodynamic balance methods. Lastly, pitch, yaw, and roll control are types of maneuvers rather than mechanisms or balances that directly contribute to aerodynamic balance. Therefore, the correct option
