What principle does Bernoulli’s equation describe as it applies to flight?

Bernoulli's equation is fundamental in aerodynamics and describes the relationship between the speed of a fluid and its pressure. In the context of flight, it specifically illustrates how an increase in the velocity of air over the wing creates a region of lower pressure.

As an aircraft wing moves through the air, the shape of the wing (airfoil) causes the air to travel faster over the top surface compared to the bottom surface. According to Bernoulli's principle, the increase in the airspeed over the top of the wing results in a decrease in pressure above the wing. Conversely, the slower-moving air beneath the wing maintains higher pressure. This difference in pressure creates lift, which is essential for an aircraft to rise off the ground and stay airborne.

While other options address various principles related to aviation, they don't accurately reflect the specific phenomenon described by Bernoulli’s equation in this context. Understanding this principle is crucial for comprehending how lift is generated during flight.
