The lift and drag imbalance between the left and right ailerons creates adverse yaw. A pilot can prevent adverse yaw by using rudder, and making sure that a turn is coordinated. In this situation, you must add the right rudder to correct for adverse yaw. The differential lift and drag are the main causes of adverse yaw.

Adverse yaw is a side effect of aileron use, countered by rudder input. The asymmetry between the top and bottom surface of the wing is called wing camber. The downward movement of the aileron increases the asymmetry and, therefore, the camber while raising the aileron reduces the wing camber. What Is an Aileron?

The aileron on the right wing deflects down, increasing the camber and creating more lift. While the tilting lift vectors are an important source of adverse yaw, drag also plays a part. Any time a wing creates lift, it creates induced drag. This drag imbalance amplifies the adverse yaw. The lift imbalance causes the roll.

One is the upper wing surfaces curvature compared to the lower surface, called wing camber. High camber generally promotes more airflow deflection, thanks to something called Bernoullis Principle. However, its even possible to generate lift from a wing with symmetrical upper and lower surfaces, that is, without camber.
