'''ප්‍රහාරක කෝණය''' (<math>\alpha</math>, [[alpha (letter)|ඇල්ෆා]] නම් වූ [[ග්‍රීක හෝඩිය|ග්‍රීක අක්ෂරය]])
'''ප්‍රහාරක කෝණය''' (<math>\alpha</math>, [[Greek alphabet|Greek letter]] [[alpha (letter)|alpha]]) is a term used in [[aerodynamics]] to describe the [[angle]] between the airfoil's [[chord (aircraft)|chord line]] and the direction of airflow [[wind]], effectively the direction in which the [[aircraft]] is currently moving. It can be described as the angle between where the wing is ''pointing'' and where it is ''going''. The amount of [[lift (force)|lift]] generated by a wing is directly related to the angle of attack, with greater angles generating more lift (and more [[drag (physics)|drag]]). This remains true up to the [[stall (flight)|stall]] point, where lift starts to decrease again because of airflow separation. Planes flying at high angles of attack can suddenly enter a stall if, for example, a strong wind gust changes the direction of the relative wind. Also, to maintain a given amount of lift, the angle of attack must be increased as speed through the air decreases. This is why stalling is an effect that occurs more frequently at low speeds. Nonetheless, a wing (or any other airfoil) can stall at any speed.

Using a variety of additional aerodynamic surfaces &mdash; known as high-lift devices &mdash; like [[leading edge extension]]s, [[fighter aircraft]] have increased the potential flyable alpha from about 20° to over 45°, and in some designs, 90° or more. That is, the plane remains flyable when the wing's chord is perpendicular to the direction of motion.
