A re-evaluation of evidence and logic provides novel explanation of how lift is generated by a wing. Newtonian mechanics (Force = ma) is shown to provide a more simple, straightforward and accurate explanation of lift and than currently available. This approach is different to the old Newtonian explanations of lift based on a change in momentum of the relative airflow, or airflow turning created by wings.  

According to Newtonian mechanics, wings with a positive AOA flying through a mass of air (m), that they accelerate (a) downwards, to create a downward force (Force DOWN). The equal and opposite upward force generated provides lift. See Fig. 1a. This process can be summarized by the equations: Force DOWN = ma = Force UP (Lift). Taken a step further, Newtonian mechanics based on the mass flow rate can better explain active lift generation using absolute airflow analysis.
