Question below from Instrument written exam: Question from exam: Should you experience uncommanded roll due to icing forward of the ailerons what is the most appropriate response? Answer: reduce AOA by increasing airspeed or extend flaps to first setting. My comments: I understand the logic of reducing AOA and increasing airspeed but I do not understand how does flap extension help to resolve roll. Feedback appreciated.

    Aim is to Reduce the angle of attack. this will be done by increasing speed. or else extend the flaps. with flap extension your coefficient of lift will increase and effective angle of attack will reduce.
