Daniel Bernoulli
Bernoulli’s principle helps explain that an aircraft can achieve lift because of the shape of its wings. They are shaped so that that air flows faster over the top of the wing and slower underneath. Fast moving air equals low air pressure while slow moving air equals high air pressure. The high air pressure underneath the wings will therefore push the aircraft up through the lower air pressure.

BERNOULLI'S PRINCIPLE APPLIED TO AIRPLANE WINGS
An airplane's wings are shaped to make the air flow faster on the upper side than on the lower side. The upper side is curved upward, but the lower side is quite flat. As the airplane moves, air flows past it. Air slows down when it hits the front of the wing. some of the air flows along the top part of thewing. Some of it flows along the bottom part of the wing.The cirved top of the wing takes up more space than the bottom of the wing. When the air gets to the wing, it is forced to move up and is squeezed betwen the wing and the other air in the sky. That makes air on the top of the wing move more quickly than air under the wing. Whenever air moves faster, air pressure is lower. The wings are pushed toward the place with the lowest air pressure, that place is up. The faster an airplane moves, the faster the air moves over top of the wing. That means a big difference in air pressure between the top and the bottom of the wing. The big difference in air pressure is what keeps the plane up. This is known as Bernoulli's Principle.
BERNOULLI'S PRINCIPLE: if the speed of air is low, the pressure is high, and and where the speed of air is high, the pressure is low.
In order to keep the airplane in the air, the force of lift must overcome the force of gravity that pulls the plane to the earth. When air moves across a surface it creates low pressure. The faster the air moves, the lower the air pressure. Thus the higher pressure under the wing lifts the airplane.
