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.
How airplanes can fly in air in spite of being heavier than air?
The air pressure under the wings is greater that the pressure over the wings creating lift.
How do planes stay in the air and keep flying?
Because the air-pressure under their Wings is greater than the air-pressure above their Wings. See the aero-foil.
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
As 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
An air plane can fly because there is blank on its wings?
"blank on" = greater convex curvature on the upper surface of
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.
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?
What type of airplane, how much does it weigh, and how fast is it traveling. Is it flying level to the horizon, or is it increasing/decreasing elevation. You have to take in to account these factors before you can answer that question.
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.
What two factors determine the amount of lift achieved by an airplane?
velocity and the difference in pressure above and below the wings
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.
