Because the air-pressure under their Wings is greater than the air-pressure above their Wings. See the aero-foil.

Do planes have gravity?
Planes are pulled down by gravity, just like everything else. But at the same time, they're wings are being pushed up by air pressure, so the forces balance out and they stay up in the air.
What is the relationship between altitude and air pressure to explain why rescue helicopters have a difficult time flying at altitude over 6000m.?
The higher you are from the Earth's surface - the lower the air pressure is. Helicopters are heavy machines - requiring a huge amount of effort from the rotor blades to keep it airborn. The lower the air-pressure, the harder the rotors have to work to keep the craft flying.
What is the force that enablesplanes to stay in the air?
air pressure. low pressure above wing high pressure below caused by shape of wing if air was thinner (no oxygen in atmosphere) planes would need rockets on them instead of jet engines
How do planes stay up?
Lift pushes the airplane up. The way air moves around the wings gives the airplane lift. The shape of the wings helps with lift, too.
How many planes does the US Air Force have in all?
about 6000
When pilots are flying planes why do they have to keep in close touch with air control?
Because if they dont they miight get lost! Hope this helps :)
What flying transport did people use years ago?
Air planes
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 is the force that enables planes to stay in the air?
Lift
Where planes are put?
Planes are parked in the airport. They are checked for performance and gas is entered. Otherwise, they are in the air, flying most of the time.
What was the flying circus?
Barnstormers who flew aircraft during an air show. The planes were brightly colored.
How does an airplane stay stable in the air?
to keep a plane stable in the air it has different control surfaces or panels to allow the pilot to adjust the position of the plane in the air. Some modern fighter jets such as the Eurofighter Typhoon are deliberately made to be unstable so the jet is more maneuverable or agile in the air. planes like this have powerful computers to adjust the flaps and control panels hundreds of times a second to keep the plane stable when it's flying normally.
Can air planes fly?
No... planes stay airborne because the air flowing on the underside of the wing is moving faster than the air flowing over the top of the wing. Without air movements - the plane cannot fly.
Can planes fly without air?
No... planes stay airborne because the air flowing on the underside of the wing is moving faster than the air flowing over the top of the wing. Without air movements - the plane cannot fly.
How many planes are flying at once?
On average, there are about 9,700 planes in the sky at any given time. This number can vary depending on factors such as time of day, air traffic, and geographic location. Flight tracking websites like Flightradar24 can provide real-time information on the number of planes in the air.
Which was invented first jets or planes?
Planes. before they could master the creation of jets they first had to find out how to stay in the air using a motor and a frame light enough to glide through the air.
