Definition
The primary flight control in the cockpit used by the pilot to operate the ailerons and elevator. Turning the yoke left or right deflects the ailerons to control roll, while pushing or pulling the yoke moves the elevator to control pitch.
Plain English
The wheel-shaped handle in front of the pilot used to steer the airplane in the air. Turn it to bank the wings, push or pull it to point the nose down or up.
Context Anchor
Seen in the cockpit during normal flying and in emergency discussions about loss of elevator control, where pushing and pulling the yoke may no longer move the nose as expected.
Derivation
Yoke' originally referred to the wooden crosspiece placed across the necks of a pair of oxen so they could pull a plow together. The aviation control was named for its similar shape — a horizontal bar with two grips, one for each hand.
Why Pilots Care
Correct yoke inputs are required to maintain attitude and recover from upsets; in loss-of-elevator situations the yoke may be used with trim to establish a controllable pitch attitude.
Analogy
Like a car steering wheel that also moves forward and back, the yoke lets the pilot both steer and climb or descend.
Intuition Check
Do not think of the control yoke as just a steering wheel. In an airplane, turning it helps bank the airplane, while pushing or pulling it controls the nose up or down.
Example Sentence 1
After takeoff, the pilot eased the control yoke back to establish a steady climb.
Example Sentence 2
After the elevator cable failed, the pilot held slight forward pressure on the control yoke while trimming for level flight.
