What is the primary function of the control yoke in an aircraft?

The primary function of the control yoke in an aircraft is to manipulate the ailerons and elevator. The control yoke is an essential component of the aircraft's flight control system, allowing the pilot to control the pitch and roll of the aircraft. When the pilot pulls back on the yoke, it raises the elevator, which increases lift on the tail and causes the aircraft to climb. Conversely, pushing the yoke forward lowers the elevator, enabling the aircraft to descend.

The ailerons, located on the wings, are controlled by turning the yoke left or right. This movement tilts the wings, allowing the aircraft to roll and change direction. The design of the control yoke provides pilots with a direct and intuitive way to manage these critical aerodynamic functions, making it a fundamental part of flying an aircraft. The other options, while related to aircraft operation, do not pertain to the primary flight control functions provided by the yoke.
