The rotation of an aircraft, ship, or missile about its vertical axis so as to cause the longitudinal axis of the aircraft, ship, or missile to deviate from the flight line or heading in its horizontal plane
Yaw is the left or right angle of the vehicle nose, relative to the direction of motion, in the horizontal plane
A vessels motion rotating about the vertical axis, so the bow yaws from side to side; a characteristic of unsteadiness
If an aircraft or a ship yaws, it turns to one side so that it changes the direction in which it is moving. As the plane climbed to 370 feet, it started yawing He spun the steering-wheel so that we yawed from side to side. if a ship, aircraft etc yaws, it turns away from the direction it should be travelling in
Turning of the gyroplane to the right or left by changing the direction of the airflow over the tail surface through the use of the foot petals
