Bernoulli's equations and Newton's are not mutually exclusive or somehow
additive - they are just looking at different aspects of the same thing
and both explain 100% of lift.

I'm not sure what hyou mean by this. One supposes that Bernouli's
equaitons are derived using Newtoniam mechanics and the
ideal gas law (it has been a long time since I took fluid mechanics
but don't see that there is anything else to work with). For that
matter
the ideal gas law can (probably) be derived using Newtonian mechanics.

Is that what you meant?


This does NOT disprove the notion that there is localized downward
flow from some parts of the aircraft. However, there is no NET flow
of air down or up from airplane wings or helicopter blades. Otherwise,
ambient pressure at ground level would steadily increase as more
and more aircraft pushed the air down...

But this seems a bit irrelevant. When I go to and from work in my car,
there is no net movement by my car either, since when I get home I park
it in the same place. But in the discussion of whether my car got me to
work or not this is irrelevant. Either that or I'm paying for fuel and
merely imagining I go to work .

Precisely. Flow is irrelevent.
