Basis working of an Airplane;
 |
| Propeller |
The engine provides the thrust that pushes the aircraft on the runway, After travelling certain distance the airflow on the wing surface is sufficient enough to create sufficient lift to counter weight and provides upward acceleration to ascend.
The thrust can be obtained by the various engines,the most commonly used in light weight aircraft is Propeller engine.
Like the fan pushes the air outward and by newton 3rd law is being thrown backward itself, Similarly but in different way, The propeller blades are so twisted so that it sucks the air in as a result by Newton 3rd law, it is forced forward. This is the thrust.

The lift is created on the wing by the beautiful principle of pressure difference of air between the Upper surface and Lower surface of the wing. The pressure below the wing is higher than the Upper surface. So net force is upward, This force is known as lift.
The pressure exerted by the flow depends on the shape of the surface it follow on.The Upper surface is more convex than lower surface.

Flow over the Wing(2d cross section is shown)
As a resultant of both the forces( Net lift and Net Thrust) airplane fly in the air.
