There has to be lesser air pressure on the top of the wing to provide lift.
Lower above, and greater below. That's what enables the wing to create lift.
Lift occurs in an aircraft wing because the wind speeds up as it goes over the top of it. The wind is traveling at relatively the same speed over the bottom. The faster air that travels over the top causes the wing to have lift because the air pressure is lower over the top therefore the wing 'rises' in a way. Hope this helps :)
The lower surface of the wing experiences greater air pressure during flight due to the Bernoulli principle, which states that as air speed increases, air pressure decreases. This pressure difference creates lift, allowing the aircraft to stay airborne.
If the mass of an object is greater than the force of lift, the object will not be able to overcome gravity and will not be able to lift off the ground. It is important for the force of lift to be greater than or equal to the mass of the object for it to be able to achieve lift.
This phenomenon is known as lift and it occurs when the pressure on top of an airplane's wings is lower than the pressure below, creating a force that lifts the aircraft.
Low. High on the bottom low on the top creating lift. The faster the airflow the greater the pressure difference and the greater the lift.

Generally, lift is created when the pressure below an object is greater than the pressure above it. For example: an airplane wing is curved on top to allow for air to seamlessly pass over, creating low pressure on the upper surface and the wing is obstructed on the bottom, creating higher pressure to lift the wing. As for a helicopter, the air is pushed down by the propeller, causing high pressure below the rotation plane, causing lift.
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.

The flow of air over the top surface of the wings provides the lift that holds the plane aloft. The greater the velocity of the flow of air over the wings, the greater the lift. If the plane slows down sufficiently, and the flow of air is reduced enough, there will not be enough lift to hold the plane aloft, and it will begin to fall. When that occurs, it is called a "stall."
An aircraft in flight experiences an upward lift force, as well as the thrust of the engine, the force of its own weight, and a drag force. The lift force arises because the speed at which the displaced air moves over the top of the airfoil (and over the top of the attached boundary layer) is greater than the speed at which it moves over the bottom and because the pressure acting on the airfoil from below is therefore greater than the pressure from above,This is how planes get lift.
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.
