Well yeah, that's the canned answser. I didn't want to start CFI stuff, but if asked, "Why is there relatively low pressure on the top of the wing", and answereed "Bernoulli" gets the job done but doesn't answer the question.

But why does the Bernoulli effect take place? "Because it's curved" isn't exactlyh correct answer either.

Lift is entirely created due to the shape of the wing. The upper surface of the wing is always bulged out more than the lower surface is. The air that meets the front edge of a wing must get past it, to meet up again after the wing has gone by. The bigger bulge of the top side of a wing means the air has to move a little faster to cover the longer distance than air that went under the wing where the path was straighter. Lift is the effect of this difference of pressure above and below a wing. Lift depends on the shape of the wing, the velocity of the air and the density of the air.

Wholly Crap! Who Cares as long as it works!

The bigger bulge of the top side of a wing means the air has to move a little faster to cover the longer distance than air that went under the wing where the path was straighter.

Why does it have to move faster? How does the air on the wing "know" that it "must" "move faster"? They're on different sides of the wing, aren't they? Why would air, hitting a bulge, suddenly accelerate to meet back up with its compadres? Bernoulli, as everyone know, showed how this works, but it's not because of air having a little chat from the top of the wing to the bottom of the wing.

This is the standard answer to which I was referring. A quick Google search will probably get you the rest, but I find it amusing that this small amount of detail satisfies the average pilot. It didn't satisfy me, because I didn't understand why all this air has to "meet back up". It doesn't.

i actually got that from google here's the link:

i wanted to sound smart first before i 'fessed up to copyright infringement. and i'm with flyinscotsman, by the way

I bet only 1 out of 10 on Flightinfo know the way a wing really works.

Not one explaination here is truly correct. In fact they are all way off base. After much research, including an advanced aerodynamics class, and study of "Aerodynamics for Naval Aviators", I believe I am a pretty good expert on how a wing works. The answer is simple - Money.

Lifties

What idiots! Everyone knows there are little guys on the wings called Lifties. They just lift the airplane up by grabbing the air. Let the wings get too steep and they fall off, though. This is aerodynamics 101! Get a grip on reality folks! WS

nevermind

 

[sf260pilot]

What makes an airplane fly? Money! No bucks no Buck Rogers!

 

[say again]

The real question is what is the formula for lift???? :erm: :beer:

It is way too easy to become a pilot in the USA. You are right THEY GIVE YOU THE ANSWERS. Then when he takes his practical he will again know what the examiner is going to ask because he will pick the easist DE he can find and his instuctor will prep him for that DE and the questions he is going to ask. Of coarse, if the DE asks too hard of questions the CFI will not send his students to him any longer and the DE will lose money.

The FAA should not give out all the answers to test and students should call the FAA for a checkride and then they should assign you a DE.

The FAA only gives out the questions. Gleim and the others give you what they think the answers are. The way I understand it, someone sued the FAA under the Freedom of Information Act and the courts ruled they had to release the questions.

Probably part of the reason us U.S. aviators don't get much respect outside the U.S.

Not that we get much here either...................

OK........................ you're a friggan genius.................. la de DAH!!!!

so what is the answer?

Lift is entirely created due to the shape of the wing. The upper surface of the wing is always bulged out more than the lower surface is.

T-38's have a symmetric wing. It still flies... if I remember correctly...
