What is the primary role of the yoke in an aircraft?

The primary role of the yoke in an aircraft is to control the ailerons and elevators, which are crucial for maneuvering the aircraft. The yoke is essentially the control wheel that pilots use to change the aircraft's pitch and roll by altering the position of these control surfaces. When the pilot pulls back on the yoke, the elevators at the tail of the aircraft rise, causing the nose to pitch up. Conversely, pushing the yoke forward causes the elevators to lower, making the nose pitch down.

Turning the yoke left or right moves the ailerons on the wings, allowing the aircraft to roll in that direction, which aids in turning the aircraft. This direct control of pitch and roll is essential for maintaining altitude and direction during flight.

The other options are related to different functions but do not accurately describe the primary purpose of the yoke. For instance, managing engine power pertains to throttle controls, and navigating with GPS involves electronic equipment that is separate from the mechanical flight controls operated by the yoke.
