I am not a pilot ,but since they want an 8,000 ft or longer runway to take off with fuel and passengers I would think a lightened 777 could take of in 5500 feet.
You don't have to worry about passenger comfort. I believe passenger comfort and safety is why runways are so long. You don't want to terrorize the flying public on landings and takeoff on short runways.
There must be some Freeper commercial pilots or airport people who can better answer the Question. - Tom
No.
Runway length required for airline aircraft is a simple mathematical calculation.
How long required to reach Vmc (minimum controllable airspeed with one engine inoperable) and distance to reach that speed and abort and come to a full stop and remain on the runway.
The distances vary with field altitude, temperature, weight, runway gradient and wind direction/velocity.
