Well. I can't add to the Bernoulli discussion because it's over 30 days
old or has been closed by the moderator. (Remove it from the list,
then). And someone tell us how to explain how circulation induces lift
to a budding pilot. Bernoulli is easier to understand and demonstrate.
Oh, yeah, FWIW, a supercritical wing produces lift because it's at an
angle of attack, just like a symmetrical or plane surface airfoil is to
develop lift. And if in ground effect, lift is still developed but
because circulation is limited by the presence of the earth's surface
below the wing, less drag is experienced, hence 'float' is experienced.
