Definition#
Adverse yaw is a yawing moment in the direction opposite to a turn, caused by the downward-deflecting aileron (on the rising wing) producing more induced drag than the upward-deflecting aileron on the descending wing.
Why It Matters Operationally#
Without rudder correction, adverse yaw produces uncoordinated flight (slip or skid). Pilots apply rudder in the direction of the turn to coordinate. Differential ailerons and Frise ailerons help reduce adverse yaw.
