How fast does a plane have to go in order to get off the ground?

planes can take off when the lift produced by the wings exceeds the weight of the plane - some variables that determine lift are the speed of air moving over the wings, angle of the wing to the air movement and the shape of the wing which can be changed with the flaps or slats
so its not the ground speed that determines when a plane can lift off but the air speed which can vary with wind speed and direction - and it differs depending if flaps or slats (flaps on the front of the wings) are deployed as they increase lift
another factor that can change lift is air temperature and preasure - higher temps and lower preasure reduce lift and so require more air speed to lift off
the amount of lift required for each plane is determined by not only the weight but the amount of drag from shape of the aircraft and the shape of the wing - which is why take off speed can vary greatly from plane to plane
take off speed can vary from about 32 knots (about 37mph) with a piper cub to nearly 180 knots (about 205 mph) with some supersonic jets whose tiny wings don't produce much lift at slow speeds
some small light high lift aircraft like the piper cub if taking off into a headwind that is equal to their takeoff speed can take off like a helicopter straight up with no ground speed at all

How fast does a 757 have to go in order to get off the ground?
It need to be moving at a speed of 160 MPH to lift off.
Does a plane go fast when taking off?
Yes. A plane goes very fast when taking off. For example, A Boeing's takeoff speed is 280 kph.
Is a plane really fast?
yes a plane is very fast compared to a car it goes about 30 times faster than a car while the plane is taking off
Can airplanes take off with the wind?
Depends on how strong the wind is, how long the runway is, how heavily loaded the plane is etc - but generally, yes.What gets a regular airplane off the ground is how fast it's moving through the air. If the air is moving with the plane - as in a tailwind - it takes longer/more runway for the plane to reach the airspeed needed to fly.
Who lands airplanes control tower or ground control?
Air control lands the plane. They also take the plane off, and pretty much get the plane from point A to B. As soon as they land and turn off the runway, Air control hands them off to ground control which brings them to the gate and from the gate to runway for take off again...
How does the 747 lift off the ground?
The engines provide thrust, making the plane move forward. As the plane picks up speed the air flows over the wing, creating lift. Once the lift reaches a certain amount, the plane lifts off the ground.
Can you land and take off a plane on tom clancy's hawx?
No, if you try to land on a runway, your plane explodes when you hit the ground.
How do airplanes takeoff?
Airplanes need to generate lift in order to take off and fly. The way they do this is to go fast enough on the ground so that the air passing over the wings generates lift in accordance with Bernoulli's principle. When sufficient speed is attained to generate the necessary lift, the plane will fly.
What is the part that does the most in aiding a commercial jet liner lift off the ground?
The pilot. All the mechanical parts on the plane are important, but if a pilot doesn't start the engines, taxi to the runway and open the throttles, the plane won't lift off the ground.
What describes the angle between level ground and the path of a plane taking off?
acute angle
What are the 4 stages of getting a plane off the ground?
taxi, run up, rotate, flaps
How many seconds does it take to take off in a plane?
Basic 737 wii be off ground in 15 seconds from commencing roll
