The shape of the wings help the aeroplane to fly.It is shaped as an Aerofoil. The front edge(leading edge) is rounded and thicker. The rear edge (trailing edge) is thinner and tapers sharply.
The upper portion of the wing has a larger surface area than the lower side. When the wing is pushed forward by the power of the engine(Thrust), the leading edge cuts through the air.This divides the air equally between the upper and lower sides of the wing.Since the air on the upper side has to travel a longer distance and the air on the lower side, an upward vaccum is created along the upper surface of the wing(Lift).This causes the wing to lift upwards, which also causes the aeroplane to climb in the air.
The larger the wing surface the better the lift with relatively lesser thrust.
That is why older engine powered, propellor aircraft have the capability to fly at lower speeds than jet aircraft.

This is because the aeroplane wings are designed in such a way that the wind over the wing flies at a much greater pace than to the bottom of it. Because of which air pressure below the wing becomes much mor ethan top of the wing; which ultimately lifts the aircraft. This phenomena is known as upper thrust.Once in air, the craft uses newton's 3rd law(Every action has equal and opposite reaction). from the jets of the aeroplane gases move out at high speed which produces equivalent opposite force which drives the plane

the aeroplane flys because the wing is shaped so the air flowing over the top of the wing has less pressure on the wing thus creating lift. when the lift created is greater than the force mantained by the acceleration of gravity the plane is able to fly. the other method is to have the engine to create enough thrust so that the momentum would creat a low earth orbit by said craft

An aeroplane flies because air moving over and under its surfaces, particularly its wings, travels at different velocities, producing a difference in air pressure, low above the wing and high below it. The low pressure exerts a pulling influence, and the high pressure a pushing influence. The lifting force, usually called lift, depends on the shape, area, and tilt of the wing, and on the speed of the aircraft. The shape of the wing causes the air streaming above and below the wing to travel at different velocities. The distance over which the air must travel above the curved upper surface forces that air to move faster to keep pace with the air moving along the flat lower surface.

If you ask anyone that owns a plane what keeps it up in the air they will tell you, money.

It is the airflow over the top of the wing that gives lift to the wing. This is done by the way the wing is shaped. The air is separated from the wing along the curve of the wing. As the air tries to separate from the wing it pulls the wing up.

You may see this effect by holding a round glass under a stream of water. You will notice how the water curves around the glass. The water is pulled along the surface of the glass. Air does the same thing along the wing of a plane.

the shape of the wing causes a increase in air pressure to the bottom of the wing and a decrease of air pressure to the to creating what is referred to as "lift" when sufficient lift is created the air craft be comes well ,, air-born hope that helps

the shape of the wings and the forward motion provided by the engines create lift.
