Essentially there are 4 aerodynamic forces that act on an airplane in flight; these are lift, drag, thrust and gravity (or weight).
In simple terms, drag is the resistance of air (the backward force), thrust is the power of the airplane's engine (the forward force), lift is the upward force and gravity is the downward force. So for airplanes to fly, the thrust must be greater than the drag and the lift must be greater than the gravity (so as you can see, drag opposes thrust and lift opposes gravity).
This is certainly the case when an airplane takes off or climbs. However, when it is in straight and level flight the opposing forces of lift and gravity are balanced. During a descent, gravity exceeds lift and to slow an airplane drag has to overcome thrust.

How an airplane floats in the air?
The lift generated by speed of the wing supports an aircraft in the air.
Why does an airplane floats in the air?
Everyone pick up their seats to keeps plane float.
Does a hot air balloon float or fly?
A hot air balloon floats in the air because it is buoyant due to the hot air inside the balloon being lighter than the cooler air outside. It is not propelled by engines or wings like an airplane, so it is more accurate to say it floats rather than flies.
How do gliders fly with no motors?
they glide, as the name implies. it's like a paper airplane. its surface area is big so it sorta "floats" on air.
Is there a special name for the stairs that come off a airplane?
airstairs or air stairs
How do you make Mario float in Bowser's inside story?
Mario floats when you find an air leakage. He will come up to it, swallow the air, and will float.
In atmosphere why there is no reaction of any action?
Forces ALWAYS come in pairs - as in "action/reaction". The atmosphere is no exception. For example, if the air pushes an airplane up, then the airplane also pushes the air down.
Why don't fat people sink in a pool?
because the breth in lots of air and air floats because the breth in lots of air and air floats
What floats in air?
A balloon.
What floats on the air?
helicopter
Does the air above the airplane move faster than the air below the airplane?
That's true for the airplane's wings, when the airplane is flying upright.
How the airplane float?
The same way anything floats, by displacing an amount of water that weighs as much as it does. Airplanes that are meant to float on water typically either have boat-like hulls or floats whose purpose is to displace enough water to allow the airplane to float.
