Aviation Word Of The Day - Angle Of Attack (AOA)

 The angle of attack, abbreviated AOA refers to the angle at which the wind hits the wing of an aircraft.To add more detail,the AOA is the angle between the wind and the imaginary reference line of the wing.This reference line is termed chord,and only refers to the distance from both ends of the wing-leading and trailing edges(as they're called).
 The AOA of the wing plays a very crucial role as it affects the amount of Lift produced by the aircraft's wings. Lift generated by the wing is significantly affected by the AOA in such a way that,an increased AOA allows more air to rush through the upper surface of the wing, which will in turn, force high pressure from the bottom of the wing.

 A wing at a higher AOA produces more lift that a wing at a lower AOA. That's just how it works.When the pilot begins takeoff roll and increases speed while on the runway,the wing generates lift, but the plane then takes off as a result of an increased AOA.
 We can conclude by stating that lift produced by the aircraft's wing is directly proportional to the AOA. A greater AOA means more lift.
