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
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.
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.
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.
Most likely, neither. When an airplane is flying above FL 180 (18,000 feet above sea level, or 18,000 MSL) in the United States, the altimeter readings are read out based on 'pressure altitude'.Normally altitude is determined by an instrument (altimeter) that utilizes the barometric readings reported at ground reporting stations over which you are flying. However, when cruising at or above FL180, pilots use 'pressure altitude', where the altimeter is set to use 29.92 inches Hg as the barometric pressure for readings. This helps to prevent having to change the instrument settings continuously to match the ground stations, and ensures that pilots flying at these higher altitudes all have the same reference setting for height.
