The turbines under the wings of the airplane suck air in, mix it with fuel, and then compress the air/fuel mixture. As the compressed mixture exits the engine, it burns hotly, creating a lot of thrust backwards, pushing the plane forward and overcoming drag. As the plane moves forward air moving over the wings and pushing up on the bottom creates lift to keep gravity from pulling the plane down. This happens throughout the whole flight of the plane. The continuous cycle of pushing air backwards with tremendous force and creating lift with the wings keeps the airplane up.
Airplanes stay in the air due to the principle of lift generated by their wings. As the airplane moves forward, the shape of the wing causes air pressure to be lower above the wing and higher below, creating lift. Additionally, the engines provide thrust to move the airplane forward, allowing it to maintain its altitude.

What are some examples of air resists things moving through it?
Some examples of things that experience air resistance when moving through it include cars, airplanes, and falling objects like skydivers or parachutists. Air resistance is caused by the friction between the air and the surface of the object, which slows it down as it moves through the air.
What would happen to falling objects if the is removed so that air resistance disappears?
Without air resistance, falling objects would accelerate at a constant rate due to gravity. This means that they would fall faster and reach the ground in a shorter amount of time compared to falling with air resistance. The absence of air resistance would also remove any upward force opposing the motion of the falling object.
What happens when there is no air resistance while Falling?
If there is no air resistance while falling, the object will accelerate at a constant rate due to gravity. This means it will continue to gain speed as it falls without any force to slow it down.
What is it called when an object falling straight down without air resistance?
It is called Free Fall.
Why do airplanes have wings?
because airplanes have wings
Why do airplanes fly straight?
Airplanes need to fly forward in order to stay in the air. They need air passing over the wings in order to stay in flight. Without air passing over the wing, bernoulli's principle can't take effect and the airplane would fall.
What is the secret of how airplanes are able to stay up in the air?
Gravity.
How does the golden gate bridge stay in the air without falling?
It is suspended with the big wires that go to the towers form the edges of the bridge
Why is there an absolute ceiling for airplanes?
Because the air gets thinner with more altitude, and at some point the thin air can no longer give enough lift for airplanes to stay aloft.
What is gliding?
gliding is falling but with style so if you put a kite on your back and fall of a cliff you will feel like your flying but your falling in angles and in slow motion
Can airplanes fly without air?
No, the air is what allows for lift. The only way an airplane can "fly" without air is if the downward force of gravity didn't exist.
Can airplane fly without an air?
No. Airplanes need the flow of air over the wings in order to produce lift.
Why do airplanes fly about 12 km of the earth's surface?
12km and above is the stratosphere . Human life cannot exist with that air pressure.The airplanes stay just to the peak of the troposhere.
Does airplanes sometimes stop in air?
NO, airplanes have to keep moving in the air.
How do airplanes protect people from the decreased air pressure when flying at high elevations?
When flying at hight altitudes (+12,000FT) planes pressurize the cabin so passengers can stay conscious without wearing oxygen masks.
What makes an aircraft to stay in the air when all engines fails?
Lift on an airplanes wing is what makes it stay in the air. Of course, lift diminishes the slower you go so eventually the plane will lose lift and begin to fall.
A flight can stay air with out moving?
No... a flight cant stay in air without moving..even for a second....but some of the fighters and helicopters can stay in air for minutes or hours..
