  • This term sounds threatening, but it merely describes the position of the wing relative to airflow.

    • For an airfoil to work, the leading edge of the wing must be inclined upward. The more it's inclined, the greater the angle of attack. Put another way, the angle of attack is the angle between the chord, or midline, of an airfoil and the direction of the surrounding undisturbed flow of gas or liquid.
