I have been reading these know-it-all sites about equal transit time fallacies and everyone writes  like they understand it. your explanation is crap. all it is is a parroting of what you heard someone else say. which means you didn't understand the equal transit time theory in the first place. you are just jumping from following one religion to following another.</p> who says!!

At slow speeds, you can reach it with a 20 degree Angle of Attack. AoA may create lift at all speeds, but certainly not enough to overcome weight.</p> You’re ignoring Critical Angle of Attack.

As for the foil-helmet-types that can't fathom how a fast moving aircraft can fly upside down using a lift-generating wing, did you consider the <em>other</em> control surfaces on the aircraft and the speed involved? Certainly the Wright Flyer would have had a tough time flying upside down, but it didn't approach anything near the speeds of todays (even light, recreational) aircraft. Once a plane has sufficient speed, flying upside down is achieved only at a considerable loss of lift efficiency, due mostly to the angle of attack required to fly "level" while upside down</p> Uh, no offense, but the equal transit theory, as you state, is a misunderstanding of the Bernoulli Principle.

I am a freshman @ the UCLA. I am planning to major in Physics. As marc said, planes can fly with a simple wedge design these days simply because we can build planes with great trust to weight and strength to weight ratio. Thus, Upside-down flight is explained by Angle of Attack, not wing shape (Equal Transit Time). By the way, i came across these excellent <a href="http://www.funnelbrain.com/searchResults.php?searchTxt=physics&decks=true" rel="dofollow" rel="nofollow">physics flash cards</a>. Its also a great initiative by the FunnelBrain team. Amazing!!!</p> A great post! I am a freshman @ the UCLA. I am planning to major in Physics.

And you're right, there is a direct correlation between wing area and lift (find the equation for lift – velocity squared, coefficient of lift, air density, and wing area). Don't forget that drag goes up similarly – you're not getting all that lift with a bigger wing for free. Also don't forget that it weighs a lot more.
