Airplane can fly because its body can create a force which is greater than its own weight. To create this force, airplane needs a wing (just like a bird) or in engineering we call it as lifting surface. The major lifting surface for airplane is wing. When airplane move, there is airflow moving arround its body. At wing, the airflow is different between upper surface and lower surface. This had created pressure difference between this two surface and the pressure difference had created force which is greater than airplane weight. This force known as LIFT.
Figure above show force acting on airplane during flight. A is Lift which is force that enable airplane to fly in the air. B is thrust which is force created by engine that drive the airplane to move forward. C is weight of the airplane and D is drag, force which is resist aircraft to fly. For straight and level flight, Lift is equal to weight and thrust is equal to drag.
To enable airplane to fly, there are several part that we must know.First is wing.
Second, vertical and horizontal tail.
Third is engine and propeller.
Lastly, control surface.

An aeroplane flies because air moves over and under its surfaces,particularly its wings, travels at different velocities, producing a difference in air pressure, low above the wings and high below it. The distance over which the air must travel above the curved upper surface forces the air to move faster to keep pace with the air to moving along the flat surface.
