At what speed does a boeing 747, or any plane alike, take-off at?

"Standard" take off speeds, as mentioned above? No such thing. At every max weight on any aircraft for takeoff the numbers will be very close but not every take off will be one at max gross weight. While those figures may be a good ball park estimate for a 747 at a given weight, what is the actual speed range from operating empty weight to max takeoff weight? It varies by a lot more than 5 knots.

BTW-
"V2" is NOT the rotation speed of an aircraft! That would be "Vr" and the call out is "rotate". The definition of V2 is the minimum "take off safety speed" and is predicated on an engine inoperative during climb out. It is used immediately after takeoff, before accelerating to initial climb speed, for max climb performance.

As far as "V3", I fly for an airline and it is not a standard call out. Only "80 knots" (transfer of control if need be from the captain to first officer), "V1, and "Rotate" are for our airline (other airliness may also call out V2). The cockpit take off videos at http://www.flightlevel350.com will illustrate that.

As the aircraft starts down the runway there are 3 calls the co-pilot (possibly the pilot calls out), the following are the V1, Rotate and V3 speeds. Depending on the weather, winds, temperature, weight of the aircarft and many more, these V1, Rotate and V3 speeds may vary. These are generic 747 speeds in ideal conditions. I don't have the weight numbers.

--V1-- is 145-148 knots,167-170 mph V1 is the go or no-go decision speed

--V2-- 155-160 Knots or 178-184 mph, this is the rotation speed or lift off speed

--v3-- is 180 knots or 207 MPH, this is the safe climb out speed.

Take off speeds vary by type of aircraft, weight of the plane, load, etc.

A 747 usually takes off at a speed of 180 to 200 miles an hour.

For people that don't know what the 5 call outs are here's what they are.


80 knots- so the pilot checks that there instruments are working good.

V1- After the aircraft reaches V1 it means that you can't reject take off and your only choice is takeoff.

Rotate- Rotate is a word that is used all the time, it means that the pilot can now pull the yoke back to slowly bring the front gear up as then the whole plane up at a positive rate of speed.

V2- I wont answer the whole think of V2 because im not 100% sure of what it means but I think its when the nose gear is off the ground and climbing.

Positive rate- Positive rate is called after V2 it means your at a safe altitude for the gear's to go up.


Gear up- A very simple call out the captin calls for the co-pilot or first officer to attract the gears up.

I think a good take off speed for the 747 is from 165_180 knots. But what I take off at is 170 knots with flaps set from 5-10, depending on the distance of runway and weight onboard. For landing speeds which is not apart of the question but I still would like to post is 160_170 knots but I use 160 knots. Thank you

A 747 takes off from 165-180 knots but it depends on the weather. In my opinion a avrage take off speed for the 747 is 170 knots with flaps set to 5-10.
