combination of speed through air by varied propulsion and both pressure and vacuum on wings. upper side creates high depression ( vacuum effect) resulting in lift. on underside we have build up of air pressure acting as a lift too.

Airplanes stay in the sky by having equal amounts of air pressure under the wings and over the wings. That keeps the plane level.

The aerofoil design of a planes wing provides the lift. The air has to take a longer route over the top then it does on the bottom, this means the air on top has to move at higher speed, higher speed with the same volume means less pressure, the basis of the venturi effect used in throttle bodies and carburettors. In essence a vacuum is created over the top of the wing providing lift, flaps are used to make the wing longer and give a more defined edge creating more drag but higher lift.

Through the dynamic interaction of air flowing around the airplane (lift), and the dynamic reaction of the airplane being propelled by an engine (thrust). Additionally, there are movable flight control surfaces that maneuver and help stabilize the aircraft along its pitch, roll, and yaw axes. You would need to read a complete introductory book on basic aircraft aerodynamics to fully answer your question.

How do airplanes stay in the sky? There are four forces that keep an airplane in the sky. They are lift, weight, thrust and drag. Lift pushes the airplane up.
