Assuming it as passenger aircraft and take-off speed = lift off speed
we have minimum runway length required as 80*35 = 2.8km
If it is a military aircraft the length will reduce further to minimum unstick speed
they help an airplane bank (turn) after they takeoff
No
important to take of the airplane
The aeroplane takeoff is controlled by the engine speed and the elevators.
100-280 kph.
137knots as an average
An-225 with a 1.3 million pound takeoff weight
Yes, as long it is not on during takeoff.
It is the An-225 with a 1.3 million pound takeoff weight it makes the worlds heaviest airplane.
"V1" is the speed at which the flight crew must either continue with the takeoff or abort the takeoff. It is the last point at which aborting is an option.
The maximum takeoff weight for a Boeing 767 is 315,000 pounds, that is the heaviest the airplane can be upon takeoff.
The airplane will tilt like a helicopter or just crash upon takeoff
