It's important because it is the aircraft's means of getting lift and flying.

Not a specific Pokemon knows this move. Most flying types can learn it, due to it being a flying type move.
A flying wing is essentially an airplane with the fuselage missing or embedded into the wing. The aircraft appears to be largely just a wing. The B2 bomber is a flying wing. There are other examples. The ultralight of many years ago called the Mitchell Flying Wing was a wing with the pilot slung underneath. There are other examples. They tend to have control sensitivities in the directions of pitch and yaw. Computers and active control surfaces assist in controlling the B2.
A flying bird's wing is in the shape of an airfoil.
Any animal with wings has a wing span. The term means the distance across the wings when they are spread out, so you can't have a wing span unless you have wings.
It depends on the angle of attack of the wing.
it was used for World War I.
The wing spar. The spar is the main structure of the wing that supports the load of the entire airplane. All the loads go through the wing into the wing spar and down to the center of it, which is called the "wing box". (You could call this the most important part,)An airplane may fly without its engines. It might be able to fly without its flight controls. But it can not fly if the wing spar breaks.

Wing Attack is a flying-type move. The Pokemon slashes the foe with its wing and is super-effective to fighting, grass and bug-types.
