What are the effects of adverse yaw in helicopters?

The effects of adverse yaw in helicopters primarily relate to the unwanted yawing motion experienced during turns. When a helicopter turns, one rotor blade generates more lift than the other, causing it to roll in the direction of the turn. However, this increased lift also leads to an increase in drag on that side, resulting in an adverse yawing motion toward the opposite direction of the turn.

This yawing effect can complicate the pilot's control inputs, requiring more coordination in the use of the anti-torque pedals to maintain a balanced turn. Understanding and managing adverse yaw is essential for pilots to maintain control and execute smooth turns, emphasizing its critical role in helicopter flight dynamics.

The other options relate to helicopter performance metrics that are not influenced by adverse yaw. Increased lift during a climb describes a positive performance outcome but is not related to yaw. Improved control during descent and enhanced stability during hover focus on different flight phases and stability rather than the yawing motion in turns.
