Hi All,

There is a long discussion ongoing in rec.aviation.piloting about
what causes lift on a plane.

Heh. I know the argument. I think it's broken out here
(sci.physics) many times.

(a) It's the Bernoulli effect due to the shape of the
wing cross-section, the way we were all taught as kids.

(b) No, it's just the angle of attack.

Probably true, in large part anyway. Just consider that aerobatics
pilots can fly their planes upside-down over considerable distances.
If Bernoulli were the sole factor this couldn't happen.

Hmm..more reasoning going on in sci.physics.

I am beginning to think I should have posted my OP in
rec.aviation.piloting to sci.physics.

Very comforting to see people focusing on physics to guide their
arguments.



Just as long as you **** off there and don't ever fly an airplane.

All of the posts I have seen in reply to yours are either completely
wrong, partially wrong or just off the wallm so you'll be in good
company.
