an opposite force that is lift.

of the aerofoil of the wing ...

The air is diverted because the wing has a positve angle of attack. It can be
perfectly flat and it will still generate lift.

downwash occurs after the wing has passed. how does it transmit its
effect to the wing? magnetism?

Sorta. The girl lift fairies push from underneath whilst the boy lift
fairies pull from up top. The obese lift fairies just hang on and
thus produce drag.

EXACTLY! GOD, somebody FINALLY nailed it. The ones that can't hang on
slam into the elevator and produce downwash.

Noooooooooo! It's the beating of the farie wings that makes downwash!
What do you think anables them to keep the wing up. Really, the
knowledge of simple airyfairey dynamics here is abysmal.

No, there are no fat faries -fat faries would not be able to fly and
they would die. It's transvestite fairies that produce drag,

Must be that built in parasite drag :-)

Downwash is the result of the wing's passing. The wing accelerates air above
it downwards. That downward movement continues after the wing has passed, and
it is called downwash. It is the acceleration that produces the downwash that
is responsible for lift.

no.
what pushes the aeroplane up into the air is the pressure differences
at the surface of the wing.

the whole purpose of the rest of it is to create those pressure
differences *at the surface*.

a wingtip vortex is an example of pressure differences not at the
surface and those just cause drag.

keep at it son. one day it is sure to sink in.

You need not involve chaos theory, although some posters seem to try.

By this thread I no longer consider it a theory.
