The lift and drag imbalance between the left and right ailerons creates adverse yaw. The changes in aerodynamic forces that occur during aileron deflection cause adverse yaw. When an aircraft rolls, the ailerons travel in opposite directions. The differential lift and drag are the main causes of adverse yaw.

At first glance, ailerons look like ordinary hinged panels on the wings, but don’t be fooledthey’re important for keeping an aircraft both stable and maneuverable. But theres much more to ailerons than just rolling left or right. Or how do modern airplanes reduce dangerous effects like aileron flutter or adverse yaw?

We correct for the overbanking tendency with aileron opposite the turn. The aileron on the right wing deflects down, increasing the camber and creating more lift. The left wing’s aileron deflects up, decreasing lift. While the tilting lift vectors are an important source of adverse yaw, drag also plays a part.
