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. Adverse yaw is an undesirable side effect of lift production, resulting in an uncoordinated, slipping turn. This movement reduces the AOA and lift.

The higher speed creates extra lift, causing the airplane to bank further into 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. The lift imbalance causes the roll.

Key Takeaways Ailerons control the aircrafts roll by adjusting lift on each wing. Adverse yaw is a side effect of aileron use, countered by rudder input. The aircrafts wing is able to generate lift due to its shape. Why does this increase the lift? If the flow on both sides is symmetrical, the wing wont produce any lift.
