What is adverse yaw?

What is adverse yaw?

• A. Yaw that occurs only during takeoff.
• B. Yaw produced in the opposite direction of a banked turn requiring rudder input to counter.
• C. Yaw in the same direction as a banked turn.
• D. Yaw caused by tailwind.

Answer: (B)

Adverse yaw is the nose yaw in the opposite direction to the bank when you use ailerons to roll the aircraft. As you roll into a turn, the wing that’s being rolled to lift more also creates more drag, which generates a yaw moment toward the outside of the turn. Because the yaw is opposite the intended bank, you apply rudder toward the turn to keep the turn coordinated. It isn’t limited to takeoff and isn’t caused by tailwinds.
