what speed does an aeroplane take off at?

Answer 1

The specifics vary for every aircraft. But they all have one thing in common: they take off or rotate (pull back on yoke/stick) on vee-one, also known as the rotation (duh) or decision speed.

A balanced field take off definition of vee-one (V1 - with "1" as subscript) is given as the maximum speed in the ground run phase of take off at which the pilot must take the first action (e.g., apply brakes, reduce thrust, deploy speed brakes) to stop the airplane within the accelerate-stop distance and the minimum speed at which the takeoff can be continued and achieve the required height above the takeoff surface within the takeoff distance. This definition is more commonly applied to modern airliners that is required in this context.

Note though: All V-Speeds are relative to the air. Meaning, it is a form of measured airspeed rather than ground speed. Since wind conditions on the ground are never constant and they affect the performance of an aircraft greatly.

Answer 2

That depends on air density due to altitude, humidity and temp, the aircraft weight due passengers, cargo and fuel plus the size and type of aircraft for example hang glider could take off with a groundspeed of almost zero mph but Concorde would need over 200 mph A small plane around 70 mph and a commercial jet 120 to 180 mph but the airspeed is the major factor depends on the wind direction and speed . Some how I dont think you want all this

Answer 3

Varies widely, 50-60 knots air speed for a light plane such as a Cessna, 155 knots for a Jumbo, 195 knots for Concorde.

It's defined as air speed rather than ground speed, because it's motion through air that generates the lift required to take off. So, in a 55 knot wind a Cessna would (theoretically) be able to take off while stationary with repect to the ground.

Answer 4

Depends on the aircraft. Most commercial jet airliners lift off around 180-200mph (at this speed they have sufficient lift). Smaller lighter aircraft can take off much slower <100mph. Crusing speeds are different though, and a commercial airliner will cruise around 500mph. Fighter jets on the other hand have a smaller wing span for aerobatic and sonic characteristics, therefore need to travel faster to lift. They can go at speeds way in excess of 600mph when cruising (faster than sound).

Answer 5

It depends on the size of aircraft and the amount of air displacement generated by the wings. A bi plane can attain lift of at relativly slow ground speeds. some aircraft STOVL (short take of and landing) can attain altitue quickly by developing thrust under the wings while others, usually deta wing aircratf need a bit more umph to take off, but these are usually faster once airborn. Hence the variable winged aircraft favoured by most air forces.

Answer 6

It depends on the type of aircraft. Smaller aircraft can take off at speeds just over 70 or 80 kph (kilometers per hour), while others require take off speeds of around 200+kph.

It also depends on the wing surface area, engine type (jet or piston), weather conditions and the weight of the aircraft.

Therefore there is no easy answer to your question.

Answer 7

All aeroplanes are different, they have something called a drag-co-efficient to do with their shape, also planes are different weights.
Therefore a planes size and shape is limited to the power we can create with an engine. At least with today's science.

Answer 8

I would say most planes have different speeds, how-ever your average passenger plane to go on your holidays fully loaded travels about 120 mph during take-off then accelerating to approx 500 mph while in the air.

Answer 9

I'm sure it takes off at around 200 miles an hour, and then when at the desired altitude, you speed up to about 450-500 miles an hour!

But I wouldn't particularly be bothered as long as u get to where you're going safely!

Also...... sit at the front of the plane and you'll get to your destination before anyone else!!

Answer 10

The speed at which the lift in the wings is greater than the weight of the plane.
