On an airplane do the wings need more or less air to help them lift the plane?

The aircraft wing is designed in such a manner that, at speed, air would sooner go beneath the wing than above. Naturally, that lifts the aircraft into the air. Next time you are close to a 'plane, 2seater or Jumbo, have a look. The underside of the wing is quite flat, while the top has a convex curve. The distance between the leading edge and the tailing edge [front to back] is lesser on the underside than the topside. Air is like water, it finds the line of least resistance and goes underneath the wing rather than above. This action creates lift.

Why is an airplane able to fly because of bernoullis principal?
That's "principle", not "principal". The idea is that the airplane's wings are shaped in such a way that the air moves faster on the top than on the bottom. As a result - and applying Bernoulli's principle - there is less pressure on the top of the wings.
Do you weigh less in an airplane or on a mountaintop?
in an airplane
Dose lift have to be greater than weight for a plane to land?
If lift is greater than weight, the airplane proceeds up, away from the ground. If lift is less than weight, the airplane proceeds down, toward the ground.
Why does an airplane that is designed to go fast have smaller wings?
1) At higher speed you (can) get more lift per area of wing. 2) Smaller wing equals less drag.
Is gravity on hill less than on plane?
Gravity on a plane is less then on a hill because you are away from the earth, However gravity in a plane over a hill is more then gravity on a plane over a valley at the same altitude above sea level.
How much do the wings of an airplane weigh?
Airplane? What airplane? My paper airplane wings weigh less than 8 grams.
What is an airplane with two wings called?
An airplane with two wings is called a biplane. It is characterized by having one pair of wings, one on top of the other. Biplanes were popular in the early days of aviation but are now less commonly seen.
Which is correct on an airplane or in an airplane?
George Carlin had a bit on this. "I'm getting IN the plane! In the plane! Let Evil Kneivel get ON the plane. I'll be in here with you folks in uniform. There seems to be less wind in here."
Does the size of the paper airplane effect how long it will stay in the air?
With more surface area on the wings of the paper airplane there will be more air providing lift for the plane. If the mass of the plane is increased less than the surface area of the plane is increased, then the ratio of the force of gravity to force of lift should decrease, theoretically, allowing the plane to stay in the air longer. There are other significant factors in how long the paper airplane will stay air born. The Launch speed is directly proportional to the amount of air moving over the wings which provides lift. However, the larger the plane and the lighter the material is the more likely the plane will deform at high launch speeds or from launching the plane by holding to far back on the plane during launch, which will make the plain more likely to drop from lack of lift if the plane deforms too much.
Why is speed important for an airplane?
Because the more speed of the air under the wings, can produce better upward force. The wings are designed for produce more pressure of air under the plane, and when the pressure increases, it forces the plane to go up and fly. If you note the big Boing or Airbus planes, they had an accessory inside the wings which is used extended only in low speed, to increase the area of the wings and produce more force of the less air pressure they had at low speeds. When the planes had take-off, the wings are shortened, because the speed is increasing and the pressure with a short wing is enough to sustain the plain easy. At the landing, again the plane is forced to speed down and extend the wings to produce more sustain while landing and the velocity is decreasing. Some jets has the hability to change the angle of their wings by the same reason, when they are at the low speed their wings are completened open, and when they are at the higher speeds, the wings close and with less area they can plane easy and with less atrict and economy of fuel.
Sould there be big wings or small wings on a plane?
With big wings you can get lift with less trust Small wings you would need a lot of trust to keep the lift. How about a happy medium
Why does the size of a paper airplane affect flight?

Would it be easier for a plane to fly higher in an atmosphere less dense than Earths?
i No, ;it would be easier in denser air. Less dense air gives nothing for the wings of the plane to use to propel itself upwards. Less dense air would make the plane crash.
Airplane a travels 1400km at a certain speed plane b travels 1000km at a speed 50kmh faster than plane a in 3hours less time find the speed of each plane?
A=200 b=250
What is safer driving a car or flying an airplane?
It is safer to ride in a plane, as there are less annual deaths per year than cars.
How density affects flight of an airplane?
more dense metal means the plane is Heaver. so it will probably fly less distance
