Air crafts of different sizes(commercials ones), do they have constant speeds of take off-s ?

Question

many take off s have different legnth of taxing distances and take off spectacularly, the rate speed is obscure

Answer 1

Your question is really hard to understand as written. You speak of different taxing distances and take off spectacularly which make absolutely no sense. If you are asking about whether all aircraft have the same takeoff speed, the answer is no. It varies with the weight, temperature, altitude and other factors.

Answer 2

a small Cessna is at 80mph...and the bigger the faster and the more airstrip needed to take off and land...its got something to do with physics...

Answer 3

There are countless factors from weather conditions, temperature, engine de-ratings, thermal deratings, runway length, single engine ops requirements, obstacle clearance ops, weight, wing configuration, etc. etc. Generally speaking, commercial airliners all rotate (take-off) within the same speed range of 130 - 180 knots.

Now of course, small airliners (Embraer, 737, A320) are lighter and more nimble so they look like they're rocketing into the sky, while the big boys (747, 777, A380) take longer to get to speed and barely climb once airborne.

Answer 4

No. The speeds vary according to the aerofoil ( wing )design. They also vary according all up weight ( payload + fuel + aircraft )

Answer 5

No, there are two many variables, weight, weather, etc. For jet and turbo fan birds a typical lift-off speed is around 120 to as high as 180 knots.

Answer 6

Nope it all depends on the load & fuel & the weather.. but heres a rough idea Of the take off speeds:
