Principles involving lift of an aircraft

Did you knw which of these principles were applied in relation with lift of an airworthiness aircraft?
--Newtons third law.

--Archimedes buoyancy principle.

Which of these statements were correct ?


Ok, both of these principles were essential for any airplane to stay fit to fly. For a steady flight  we have to equal the four aerodynamic forces exerted on aircraft, say thrust, drag , lift and weight of an aircraft.
that's how archimedes principle helps us to equal the weight and lift, and of course we all know the newtons third law, consider the remaining two aerodynamic forces, ACTION= THRUST therefore REACTION=DRAG, simple isin't it  ?
The second image shows a special aerofoil shape gives us the required pressure difference around the wings to achieve more lift.

Am i wrong, well i've completed aeronautics back in 2010, so may be i've forgotten somethings, i too a learner, your suggestions were always welcome friends, happy learning !
