How does the wing help the aircraft to fly?

  THE WING AIRFOUL SHAPE WITH INCREASE SPEED AT THE GRAVITY POUNT WITH FLAP AND AILERON THE AIR CAMES TO THE WING FROM THE AIRFOIL SLIP TO THE END OF WING

Wing is the main part of the aircraft that produces lift for the aircraft. The lift that compensate the weight of the aircraft and helps to float in the air. 

By creating lift with the help of its shape. It works on Bernoulli's principle. 

The wings cross-section is called as Aerofoil. Top surface has more length than bottom one. Now consider air is flowing over the aerofoil. At the same instant of time, air has cover distance. Since it has less length on bottom, velocity will be low and top has high velocity. Due to this difference, a pressure force is created around the aerofoil which creates LIft Force.

The wings are the airfoil that generates the lift necessary to get and keep, an aircraft off the ground, As the aircraft gains speed, air passes faster and faster over its wings and lift is created.  Like the fuselage to which they are attached, they are made of aluminum alloy panels riveted together. The point of attachment is the aircraft's center of gravity, or balance point. Most jet aircraft have swept wings, meaning the wings are angled back toward the rear of the plane. Swept wings produce less lift than perpendicular wings, but they are more efficient at high speeds because they create less drag. Wings are mostly hollow inside, with large compartments for fuel. On most of the aircraft in service today, the wings also support the engines, which are attached to pylons hung beneath the wings. Wings are designed and constructed with meticulous attention to shape, contour, length, width and depth, and they are fitted with many different kinds of control surfaces. The control surfaces attached to an aircraft's wings and tail alter the equilibrium of straight and level flight when moved up and down or left and right.
