Why should the aileron not be used to correct for wing drop during a stall?

Using the aileron to correct for wing drop during a stall is problematic because it increases the angle of attack on the wing that is already stalled. When an aircraft reaches its critical angle of attack, the airflow over the wing becomes turbulent, causing a loss of lift. If a pilot uses the aileron control to try to raise the dropped wing during a stall, it increases the angle of attack on that wing even further. This exacerbates the stall condition, preventing recovery and leading to a more dangerous situation. In essence, trying to correct the wing drop with ailerons only worsens the stall situation.

Other responses highlight valid concerns associated with aileron use during a stall, such as adverse yaw and reduced effectiveness in lateral control, but they do not directly address the critical issue of the angle of attack and its direct relationship to stall recovery. The risk of entering a spin is another concern, as improperly managing a stall can lead to uncommanded yaw and roll, but the most immediate and significant problem with using ailerons in this scenario is the increased angle of attack on the wing already experiencing a stall.
