So, let me put down what I,understand reading the above comments Please correct me If I,am wrong.
Lift is a Combination of both Newtons Law and Bernoulli's Principle, Newtons law defines the reaction of an Aerofoil at an angle to a free stream flow of Air/fluid. An aerofoil pushes the air down which results in the air pushing the Aerofoil up, but an Asymmetrical Aerofoil would push the air downwards at greater velocity due Bernoulli's principle and thus create more Up force (lift)
Coanda effect describes the movement of this Air/fluid Particles around the airfoil and reason the air on upper surface dips below and Vice-Versa creating what we know as Wingtip Vortices.??
Inverted flight:-, a conventional Aerofoil can sustain such flight because of Newton's law but inefficient and would require higher AOA and for Symmetrical aerofoil like that of a fighter jet, it is easier to sustain such maneuvers because there is less pressure differential (Bernoulli) due to the aerofoil design.....
