A condition of flight in which the nose of an airplane tends to yaw toward the outside of the turn. This is caused by the higher induced drag on the outside wing, which is also producing more lift.

• A. Adverse Yaw
• B. Proverse Yaw
• C. Dutch Roll
• D. Coordinated Turn

Answer: (A)

Adverse yaw is the tendency for the nose to yaw opposite the direction of a roll when you bank the airplane. This happens because the wing that ends up producing more lift in the bank also generates more induced drag. The outside wing, which has to supply extra lift to help balance the aircraft in the turn, creates more drag. That drag acts off the airplane’s centerline and produces a yawing moment toward the outside of the turn, so the nose tends to swing outward before you counteract it. In flight, you counter this by applying coordinated rudder along with aileron to keep the nose aligned with the desired turn.
