What is the function of cables in an aircraft's control system?

Cables play a critical role in an aircraft's control system, primarily serving to control flight surfaces. When a pilot inputs commands through the cockpit controls, these cables transmit the mechanical motions to various control surfaces such as ailerons, elevators, and rudders. This connection allows the pilot to maneuver the aircraft effectively during flight by altering its orientation and trajectory.

The proper functioning of cables is essential for the accurate response of these surfaces to pilot inputs, contributing to the aircraft's overall stability and handling. In contrast, other options like providing power to engines, communicating with ground control, or storing fuel do not pertain to the control surfaces or the direct manipulation of the aircraft’s flight path. Thus, the focus of the cables within the control system distinctly highlights their purpose in facilitating the pilot's commands regarding the aircraft’s flight surfaces.
