where does an aircraft wing achieve its maximum lift?

Lift is nothing more than the pressure of air pushing up on the bottom of the wing.  The shape of the wing prevents the pressure on top of the wing from equalizing the pressure on the bottom.  Because the fluid moves quicker over the upper curved part of the wing, it exerts less pressure than the slower moving air beneath the wing.

Because the top side and bottom side of wings are shaped differently, air travels at different rates over the surfaces, causing lift.  The answer is C.

The different control surfaces on the wings and tail can control both the angle of the plane and the amount of lift that the wings provide, while varying the engine power can control speed. For example, before landing, a plane is going much slower than crusing speed, but the flaps on the wings are extended, creating a little more drag, but increasing the lift.

If the aircraft is pulling a load factor of 2.5 then the wing must produce 2.5*5000 kg or 12500 kg.

The largest is the Andean Condor.\n\nThe highest flyer is Ruppell's Griffon Vulture - it's 7 miles up!!!

Basically, airplane uses the same aerodynamic forces as forces that lifting your hand, when you reach out your hand through the moving car window.\nLittle slope of your hand is enough to create air force that pushes your hand up or down depending of angle.\n\nSimilarly, wind speed can elevate your sun umbrella on the beach.\nOnly difference is that an airplane creating enough wind speed by own moving straight ahead and forcing the air to push his sun umbrella (in case of airplane – sun umbrella or sloping hand  is WING )

plane starts gliding...trading potential energy of its height to kinetic energy forward to hopefully find a landing site.  this is why airplanes gain altitude as quickly as possible after take-off, so if there is an engine problem they have time to find a landing place.\n\nIf thrust is lost, gravity and lift become unbalanced with gravity winning because altitude must be lost to maintain airspeed.  drag wins over thrust since there isn't any thrust so altitude must be lost to compensate for drag-thrust imbalance.\n\nsource: i'm a pilot

1) Billy Boy's answer is exactly not the right answer. It is a common misconception that lift is generated due to the rounded "airfoil" shape, forcing fluid to travel faster on top, and thus generating a pressure gradient through incompressible Bernoulli's equation. That is INCORRECT. A flat board can generate lift if you tilt it and swing it through the air.\n\n2) I don't think you really want a mathematical explanation. Because the mathematical explanation involves complex partial differential equations, or, if you prefer, integral equations. These are known as the Navier-Stokes equations, and they govern 3D fluid flow. A fully mathematical answer would be: the wings generate lift because the solution to the Navier-Stokes equations around the wings shows an upward momentum deficit in the flow, thus generating lift on the wings.\n\n3) But really, it's quite simple. When the plane is flying, the wing is pushing air down. Not straight down, but slightly down, and by Newton's 3rd law, the wing is pushed up. (Who's doing the work? The engines are pushing the plane forward, which forces the wings to push air down.)\n\nIn fact, if you actually follow the link Billy Boy gave, NASA would tell you the same - in different and probably more confusing terms.

well, it's the area of the wing of the lifting surface, the weight of the plane, along with the pitch angle witch can be adjusted to generate more down force, but a high pitch angle would cause the plane to stall and maybe crash, also the altitude; planes can fly slower at lower altitude because the air is more dense there which means that less speed can generate enough life for it to fly..

First, look at any typical airfoil shape. It is sort of teardrop shaped, with a round end and a pointy end, but not symmetrical--one side seems flatter than the other. Let's imagine that the pointy end points to the right, the round end point to the left, the flatter side is on the bottom and the rounder side is on top.\n\nLet air flow from the left to the right. Air flowing near the airfoil at speeds that are not too fast (less than the speed of sound) is not compressible. Let's follow two tiny blobs of air that start next to each other, but approach the round end of the airfoil in such a way that one blob goes up and over the airfoil, while the other slides over the bottom. These two blobs will arrive at the pointy end at approximately the same time. But, the one going up and over as a longer path to take and therefore must travel faster. All the air molecules in a blob are actually thrashing about randomly and can collide with other air blobs nearby as well as the upper surface of the airfoil. This is true of the upper blob and the lower blob. But, if the upper blobs average speed is faster, then its molecules collide with the upper surface of the airfoil less over the trip from round end to point end than do the molecules in the lower blob. Therefore the pressure caused by the collisions of the molecules in the upper air blob on the upper side of the airfoil is less than the pressure on the lower surface caused by collisions of the lower blob's molecules with the lower surface. This means there is a difference of pressure between the two surfaces--pressure drops as you go from upper to lower surface. If the airfoil is rigid, then this difference in pressure will become a force exerted on the airfoil from below, called lift. This lift is what makes an airplane rise on takeoff as it rushes through the air with its wings whose cross-sections are airfoil shaped, rounded end into the oncoming air and flatter side towards the ground.

Lift on a wing typically occurs only in a very narrow band along the length of the wing.  Everything outside of that is only adding to friction.  So a long wing, with a narrow width (cord) has more lift and less drag since more of the wing is in that lift "band" and less causing drag.\nSo why not make all wings narrow and long?  Because of strength requirements (1) and; (2) a wide wing can increase its lift as the nose is tilted up as one does when slowing down to land.  A narrow wing would not do that and one would have to land at much higher speeds and with greater danger of stalling!

In order to create lift, the upper surface of a wing must be longer than the lower surface. That's why wings are curved. The bottom is flat and the top is curved. The F-117 doesn't have a "curve", but the upper surface is shaped with flat plates so that the upper surface is longer than the lower surface. It's not as aeordynamic and efficient as a nice, smooth curve, but I'll take not being seen over efficiency any day in a war.

Condensation. As the air moves over the wings of the plane, the moisture in the air collects on the wing. It is pulled to the wingtips where it then is blown off, and condenses into small lines of "cloud"

For what category.\nFor leg strength: Ostrich\nFor Wing Strength: Probably the Albatros- they can fly 1000+ miles withouth stopping.\nFor shear wing movement- Hummingbird\nFor neck and head- woodpecker\n\nSo it depends on what you want...

No matter what course an aircraft takes, it is flying in the atmosphere, which rotates with the earth. It is possible to find a jetstream at high altitude, and it will speed your flight if it's in the direction you're traveling. Jetstreams generally flow eastward (same direction as earth's rotation) and can hit speeds of 275 mph (see ref.). Since this is against the Europe-to-America direction, it's unlikely that a jetstream would help such a flight.\nEDIT: The original ref. (now marked [1]) is currently unavailable, but I'm leaving it here because it had an excellent illustration of equatorial-polar convection cells. Ref. 2 has a good graphic of jet stream formation.
