“... measure the tops and bottom of wings and rotos and figure the ratio or difference between the area of the top of the wing versus the bottom and estimated which wings had more lift than others.”

Keep in mind that lift is about 25% Bernoulli Effect and about 75% displacement depending on the wing cross section.

Yes. I had to search for that one. The pat answer is pressure difference causes lift and the plane achieves loft. All the pilots at the air show say this, but I remembered that aeronautics was originally studied using water. I thought, if subs move about due to displacement there must be a similar effect on planes. After a lot of stumbling about due to a lack of proper terminology, I was able to find your statement about Bernoulli vs displacement.

Thanks.

THis was a pretty good explanation of what you were talking about.
