speeds depend on the weather condition and how long the runway is but usally a 747 takes off at 150-154 knots.
About 180-200 miles per hour.
The maximum take off weight for a 747-400 is 875,000 pounds (396,890 kg.).
280kmph.
The Boeing 747's takeoff speed if 156knts or 180mph.Take off speed for 747-400 fully loaded is 155-160 knots or almost 300 km/h or 180 mph. About the speed of of an F1 racer down a long straight.The standard speed for a Boeing 747 to take off is at about 120 miles per hour.Take off speed for 747-400 fully loaded is 155-160 knots or almost 300 km/h or 180 mph.

35 knots
The lift off speed is dependant upon the weight of the aircraft. The heavier the aircraft the higher the speed. At maximum take off weight of 875,000 lbs (396,890 kgs) Vr (rotation speed) will be about 175 knots and V2 about 185 knots.
A standard 737 will take off (rotate) at approximatly 140 knots. Take off speed depends on wind speed temperature and weight etc
The takeoff speed of a Boeing 747 can vary depending on factors such as weight, runway length, and weather conditions. However, generally speaking, the takeoff speed of a Boeing 747 is around 180-200 knots (207-230 mph).
The answer depends upon several factors, but a fully loaded 747-400 taking off from a sea level airport with a temperature of 15 C would be taking off with a speen of about 185 knots.
This can vary depending on weather and weight, but can be between 180-210 knots
The Maximum Take-Off Weight for a Boeing 747-100 is 333, 390kg; a Boeing 747-200 and 747-300 is 377,842kg; a Boeing 747-400 is 396,890kg; a Boeing 747-400ER is 412,775kg and the Boeing 747-8I is 442,253kg.
A Scram jet is a jet which needs supersonic propulsion to take off. It is taken into air by another larger aircraft and is released in supersonic speed.
