The 747 generates lift by increasing its speed and angle of attack. As the aircraft gains speed, the air flowing over the wings creates lift, allowing the plane to become airborne. The engines provide the necessary thrust to propel the aircraft forward for takeoff.
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.
The zero lift drag coefficient of a Boeing 747 is approximately 0.022. This value represents the drag force experienced by the aircraft when it is not generating lift.
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.
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 weight of a Boeing 747 can vary depending on its model and configuration, but it typically ranges from 160,000 kg to 440,000 kg when empty.
About one minute from brake release to lift off at maximum take off weight.

It takes off by... 1)The pilot adding full flaps 2)The pilot adding full power 3)The pilot pulling bake on the stick and increasing lift.

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 747's max take-off weight is 910,000 pounds.
Anything in excess of 12.5 degrees could result in a tail strike on lift off depending on aircraft weight and center of gravity.
The maximum take-off weight of a Boeing 747-400 is 875,000 lbs
speeds depend on the weather condition and how long the runway is but usally a 747 takes off at 150-154 knots.
The maximum take off weight for a 747-400 is 875,000 pounds (396,890 kg.).
Perhaps. If it is possible at all, only the strongest tornadoes, capable of inflicting EF5 damage, would be capable of doing so. The heaviest object known to have been lifted by a tornado was a 180,000 lb oil tank, which is about half the operating empty weigh of a Boeing-747. Then again, a plane would be better able to catch the wind than an oil tank. Ultimately it is a moot point; if an EF5 tornado were to make a direct hit on a 747, the plane would not simply be lifted off the ground; it would be torn apart and carried away in pieces.
