It depends upon many factors; the weight of the aircraft, elevation of the airport, temperature, wind direction and speed to name a few.
It depends on the airplane. A Boeing 747 needs to go 160 knots before you can take off in it; a Cessna 172 needs to go 55 knots to take off.
If you reduce wing size the aircraft will take longer distance and will have to attain higher ground speed before lift-off.
They have no need of runway because they can lift off vertically
Yes, the F-16 is not a STOVL (short take-off vertical landing) aircraft. Not sure about the length of the runway, but it probably varies with the take-off weight of the aircraft. But the F-16 definitely needs a runway.
Not all need a long runway. The take off length depends on a number of factored such as weather wind speed, weight of aircraft, power of engines.
it depends on what type of aircraft your flying, the runway length, and the weather. here are two common aircraft flap settings for standard takeoff use: Boeing 737: set flaps to 5 cessna 172: set flaps to 10 these are two common flap settings for the Boeing 737 and cessna 172. remember, different aircraft have differnet flap settings based on weather and runway length.
long enough to take off
About a mile, yeah, a mile.
The max take off weight is 396,890 kgs.
A Boeing 757 burns around 2,000 pounds of fuel during take off. The actual amount of fuel varies based on the load of the plane.
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.
For takeoff, it requires so much thrust to get it off the ground that if it used a regular runway, it would need something like 5 miles behind it to avoid damage. So they make it take off vertically to avoid that. A space shuttle lands on a regular (but slightly longer) runway just like a plane.
