Induced drag is because of that element from the air deflected downward which is not vertical towards the flight route but is tilted a little bit rearward from it. Given that the angle of attack increases, so does drag; in a important place, the angle of attack could become so terrific which the airflow is damaged above the upper floor on the wing, and lift is misplaced whilst drag increases. This significant affliction is termed the stall.
