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.

How do you make a falling piece of paper stay in the air the longest?
folding inan aerodinamic form, like a wing.
What is it called when an object falling straight down without air resistance?
It is called Free Fall.
How is air resistance helpful?
If you are falling...the air beneath u will resist you from falling even faster.
Why do airplanes have wings?
because airplanes have wings
Which encounters the greater force of air resistance a falling elephant or a falling feather?
A falling elephant encounters a greater force of air resistance than a falling feather does. The force of air resistance can't be greater than the weight of the falling object. When the force of air resistance is equal to the weight of the falling object, the object stops accelerating, its falling speed becomes constant, and the force of air resistance doesn't get any bigger. So the force of air resistance against a falling feather can't be greater than the weight of the feather. But the force of air resistance against a falling elephant can be, and undoubtedly is, greater than the weight of a feather.
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.
Could you fly without an airplane?
Yes, helicopters are not airplanes. I think hot air balloons are considered flying. Also, people fly on hang gliders. Dirigibles are not airplanes.
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..
