The incoming stream of air, when it encounters the wings, it gets turned downwards due to the shape and angle of the wing. As the wing exerts a force on the incoming air, an equal amount of force is applied by the stream of air onto the wing in the opposite direction. The resultant aerodynamic force gets resolved into two components. The vertical component that lifts the airplane, countering the weight is called as the lift and the horizontal component that opposes the forward motion of the aircraft is called as [[drag]]. |

In most airplanes that are capable of flying inverted, the airfoil would be a symmetrical airfoil that is capable of producing lift in that position. So in an inverted airplane with a symmetrical airfoil, when the pilot pushes the control stick the angle of attack would decrease and produce a negative lift relative to the normal orientation of the plane, but in reality, it would be creating a positive lift as it is flying inverted. | In most airplanes that are capable of flying inverted, the airfoil would be a symmetrical airfoil that is capable of producing lift in that position.
