That totally varies based on the angle of the wing and air speed of the wing. It will typically be considerably less then normal atmospheric pressure.
More Information:
The atmospheric pressure on a wing in flight is subject to many variables and is difficult to assess. It varies, mostly due to wing shape and angle, and air speed. The important thing is that the pressure on the bottom of the wing is greater than the pressure on the top. This pressure differential results from the shape and angle of the wing, and the air flow across it. However, regardless of how this pressure differential is generated, it is called lift, and it's what makes flight possible. For example, as an airplane moves down the runway for take-off, it generates more and more lift as its speed increases. When the lift is sufficient to overcome gravity and friction (drag), flight happens.

Atmospheric pressure on the top of a wing in flight is?
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.
Is there more or less pressure under the wing of an airplane?
There is more pressure under the wing than is on top of the wing. This is what generates the lift for flight.
How do airplanes stay in flight?
Planes stay in flight because of bernoulli's principle. When air passes over a airplanes wing. The air that goes on the top of the wing moves faster than the air the goes on the bottom. Thsi auses a low pressure system above the wing and a high pressure system beneath the wing. The high pressure below the wing pushes the airplane up allowing it to fly.
What is true about an airplane wing during flight?
In flight, a wing has lower pressure on top and higher pressure on bottom due to Bernoulli's principle which in turn "sucks" the airplane into the air. The air on top must travel a longer distance than the air on bottom in order to meet up again because of the shape of the wing therefore causing the effects of Bernoulli's principle.
How does and aircraft becomes airborne?
There is a lot of explanation: but these are the basics: An airplanes wing is in a special shape it is flat on bottom and Curved on top. When a plane picks up speed the air must get from in front of the wing to the back of the wing. ( there cannot be a vacume!) Because the wing is curved air on top of the wing has to travel faster than the air on the bottom. The laws of physics state that as velocity (speed) increases, pressure decreases. therefore the atmospheric pressure on the top of the wing decreases and the plane rises.
Why us air drag necessary for the flight of a aeroplane?
Because air drag and flow is what gives the wings lift. Air travels faster under the wing and slower over top the wing. This creates less pressure on the top of the wing providing 'lift'.
Is there a greater or lesser air pressure on top of the wing when lift occurs?
There has to be lesser air pressure on the top of the wing to provide lift.
What would happen to the air pressure if you took a barometer from a mountain top down into a mine shaft?
the atmospheric pressure on top of a moutain would be lower than the atmospheric pressure down in a mine shaft
What is wing loading of an aircraft?
Wing Loading is the details of the distribution of pressure on an aircraft wing. An aircraft flys by producing Lift by its wings. This lift force depends on the shape of the wing that produces high pressure on the bottom of the wing and low pressure on the top. The center of the lift is usually at the 1/4 chord or 25% of the width of the wing as measure from the leading edge. The Wing Loading can be designed to produce different Lift and ensure the aircraft will be easy to trim for level flight.
Is there more atmospheric pressure at the top of a mountain or at the seashore?
yes
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.
Why is the atmospheric pressure at the top of mt Everest 5 lbin squared much less than the atmospheric pressure here on earth 14.7 lbin squared?
The atmospheric pressure is caused by the weight of the air on top of us. At the top of mount Everest, there is less air above the exhausted climber (because a lot of the air is below). Less air, less weight, less pressure.
