What is adverse yaw?

Adverse yaw occurs when an aircraft rolls into a turn and generates a yaw motion in the opposite direction of the turn. This happens due to the differential lift produced by the wings. When the aircraft is banked into a turn, the wing that is descending (the wing on the outside of the turn) creates more lift than the other wing, resulting in increased drag on that side. This additional drag can cause the nose of the aircraft to yaw towards the opposite direction of the turn, which is the hallmark of adverse yaw. Understanding this concept is crucial for pilots, as it highlights the importance of coordinated aileron and rudder input to maintain controlled flight during turns.

The other options refer to different aerodynamic phenomena or piloting concepts that do not accurately describe adverse yaw. For instance, one option suggests that adverse yaw is beneficial in a turn, which misrepresents its implications, while others mention aspects that pertain to stalls and landing techniques, which do not relate to the definition of adverse yaw at all.
