Hello, this question is about lift in fixed wing flight (airplanes).

Is it possible to calculate separately the lift generated by:
- Newton's laws (wings deflecting air particles)
- Bernoulli effect (difference in air pressure above and below the wings caused by the shape of the wings(?))

Any suggestions on how to do this?

this is just a suggestion

in newton's model use the wing area A and the air pressure P=1/3 \rho v2 to calculate lifting force f=PA

for Bernoulli it's more complicated.

If you mean calculate from scratch, both are extremely difficult.
