It's not so much that the air pressure below a wing is greater as it is the pressure above it is less. The way a wing works, is the airfoil (shape of the wing) accelerates the air above the wing. Since the air is moving faster, it lowers the air pressure, resulting in a lower pressure above, and a higher(standard) pressure below, creating lift.

When an airplane is ascending is pressure greater above the wings or below the wings?
Faster-moving air across the top of the wing lowers the pressure there. For a plane to ascend, the pressure must be sufficiently lower on top of the wing, and it will be forced upward by the greater pressure below the wing.
What gives an airplane it's lift?
Airplanes generate lift due to the difference in air pressure above and below the wings. As the air flows over the curved shape of the wing, it creates lift force by reducing the pressure on top of the wing and increasing the pressure underneath. This pressure difference allows the airplane to overcome gravity and stay airborne.
As an air molecules move over and under wings of an airplane the pressure increases below the wings to create which of the following?
Lift
Is it true When a bird flies the air pressure on the top of its wings is lower than the air pressure below?
yes
What force acts on gliders in the air?
Gravity, from the Earth, pulling it towards the ground, and Lift, applied by the air due to pressure difference on the wings (high pressure below the wing, low pressure above the wing). The faster the glider goes, the greater the Lift. Gravity does not change however.
An air plane can fly because there is blank on its wings?
"blank on" = greater convex curvature on the upper surface of
How do aeroplanes fly even though there airfoils cant flap like birds wings?
The different air pressure above and below the wings creates lift and allows the 'plane to fly given enough forward motion.The different air pressure above and below the wings creates lift and allows the 'plane to fly given enough forward motion.
How much lift is exerted on the wings of an airplane that have a total surface area of 108 m when the difference in air pressure below and above the wings is 5 percent of atmospheric pressure?
The lift on the wings of the airplane can be calculated using the formula: lift = pressure difference * wing area. Given that the pressure difference is 5% of atmospheric pressure, and atmospheric pressure is about 101325 Pa, the pressure difference is 0.05 * 101325 = 5066.25 Pa. Therefore, the lift exerted on the wings is 5066.25 * 108 = 547170 N.
As air molecules move over and under wings of an airplane the pressure increases below the wings to create which of the following?
Lift
How do wings and propellers help airplanes fly?
Wings generate lift by creating lower air pressure above the wing compared to below it, allowing the plane to stay up in the air. Propellers (or jet engines) generate thrust, pushing the plane forward through the air. Together, lift from the wings and thrust from the propellers enable the airplane to take off, fly, and land.
How can bernoulli's principle keep a bird in the air?
in a steady flow, the sum of all forms of mechanical energy in a fluid along a streamline is the same at all points on that streamline. if the air flowing past the top surface of a wing is moving faster than the air flowing past the bottom surface, then Bernoulli's principle implies that the pressure on the surfaces of the wing will be lower above than below. thus allowing the pressure below to push up on the wing, thus generating lift.
What is an interesting fact about the airplanes?
Planes cannot fly backward, if airflow above the top of the wing surface is lower than below the wings surface the aircraft will stall,
