In flight, the air pressure above the wing is less than that below it.
The air above an airplane wing in flight is at lower pressure than the air below the wing. Hope this helps.
That's true for the airplane's wings, when the airplane is flying upright.
there is less pressure above the ground so the ink inside it burlge outside and flow in airplane......
Planes fly in the atmosphere above the surface of the earth called the stratosphere.
The air pressure above the wing is lower because the air traveling faster over the curved top surface creates lower pressure compared to the slower-moving air below the wing. This pressure difference generates lift, allowing the airplane to fly.
When the air above an airplane wing moves faster than the air below it, a pressure difference is created. This pressure difference generates lift, as the higher pressure below the wing pushes the aircraft upward. This is known as Bernoulli's principle, where increased air speed above the wing results in decreased pressure and lift.
40000 feet = 7.6 miles
Bernoulli's principle explains how the faster-moving air above an airplane wing creates lower pressure, while slower-moving air below the wing creates higher pressure. This pressure difference generates lift, allowing the airplane to fly.
The lift on an airplane wing increases as the speed of the airplane increases due to the Bernoulli's principle. Faster airspeed over the wing creates lower pressure, and higher pressure underneath the wing generates lift. This relationship creates more lift force as airspeed increases.
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.
As the airplane ascends to 30,000 feet, the air pressure outside the airplane decreases. This is because air pressure decreases with altitude due to less air molecules exerting pressure on the aircraft. The difference in pressure between the inside and outside of the airplane is managed by the aircraft's pressurization system to ensure a comfortable environment for passengers and crew.
Low pressure is created over the top of the wing while higher pressure is below the wing which generates lift.
