“When forced through a constriction or across a curved surface, a fluid will accelerate, and its pressure will simultaneously decrease,” the pilot pens.
“Our fluid is air, which moves faster over the top of the wing, which is curved (less pressure) than it does along the flatter surface below (higher pressure).
“The result is an upward push, the wing floating, if you will, on a high-pressure cushion.”
In short, Bernoulli’s pressure differential, teamed with the deflection of air molecules, is what is key to a plane being able to fly.
