What are the phenomenon which let the aeroplane fly?

Answer:
Explanation:
There is four main forces at work on a flying aircraft.
The first one is gravity, the force that keeps you glued to the surface. (For flat earth theorist density: because the air above us is less dense than all material things the material thing wants to be below the lessor dense air above us)
The second force is drag, put your hand out the window of a driving car and hold your hand open so your palm faces forward, you will feel your hand wants to move backwards. This is due to the drag behind your hand as there is a high pressure buildup in front and a low pressure behing your hand.
The third force is thrust, trust comes from the propeller or turbine that forces the plane forward, same as what a balloon doen when you let a blowup baloon loose, so there is forward propultion by means of forming a “high pressure” behind the plane.
Now the fourth for is money, yes you needs lots of it to get lift.. jokes aside, LIFT is what we get when the air from the front of the main wing passes over and under the wing and is turbulend when going off the wing at the back. The upperside of a normal lightweight training aircraft has a asymmetrical wing that means if you look from the side there will be a bigger “bulge” in the upper half towards the leading eadge of the wing . The wind passing over creates a low pressure above the wing and high pressure underneath, as we have seen from above descriptions “things” always want to move from high pressure to low pressure.
So the wing wants to move upwards and you have flight as long as the speed is high enough and the wing does not exceed the critical angle of attact toward the oncoming air, then you’ll have a stall condition.
Due to the process of action and reaction.
