How are cables and pulleys used in aircraft rigging?

Cables and pulleys are integral components in aircraft rigging, primarily functioning to transmit force from cockpit controls to control surfaces. When a pilot manipulates the controls, such as the yoke or pedals, the associated movement generates tension or pull on the cables. These cables, routed through pulleys positioned throughout the aircraft, effectively transfer this force to the control surfaces, which include ailerons, elevators, and rudders.

This system allows for precise and responsive control of the aircraft’s flight maneuvers. For example, pulling back on the yoke increases elevator deflection, pitching the aircraft upward. The use of cables helps to create a mechanical advantage, making it easier for the pilot to exert the necessary force to control the aircraft effectively.

In contrast, the other options presented do not accurately reflect the main purpose of cables and pulleys in aircraft rigging. While aerodynamic efficiency can be influenced by properly rigged control surfaces, this is not the primary function of the cable and pulley system. Stabilization of the aircraft during flight is typically achieved through careful balance and control surface adjustments, not directly through the operation of cables and pulleys. Lastly, managing fuel flow is accomplished through fuel lines and pumps, which is unrelated to the physical control systems
