Re: Misconceptions: Physics of Flight: OOPS!

Here is a counter-argument. Imagine a very thin, cambered (curved)

camber. This creates lift, even though the angle of attack is changed.
Why?



OOPS! Big typo. That should read:

This creates lift, even though the angle of attack is NOT changed. Why?
