how long is the runway? how much speed plane achieve on runway?

Answer 1

It depends on the plane. A 737-800 needs about 150 knots before you rotate (lift nose up to begin climb). Most commercial Airliners are around 150 knots. 777 and 747 need a greater speed and longer runway,160-170 knots. Not every plane can land on all runways. The C-5A can only land on runways 'rated' to hold it's mammoth weight. A Cessna is about 80-90 knots and rotate.

Answer 2

Depends on the airport--bigger planes need bigger runways. Most airplanes go almost 200 mph before they get off the ground.

Answer 3

well to me it's just really really long.here is some facts i know.....
A fifteen thousand foot runway with marks at ten thousand feet, thirteen thousand feet, and fifteen thousand feet. Above the ten thousand feet mark is an airplane with no cargo; the airplane weighs 250 tons. Above the thirteen thousand feet mark is an airplane with 75 tons of cargo; the airplane weighs 325 tons. Above the fifteen thousand foot mark is an airplane with 125 tons of cargo; the airplane weighs 375 tons.
Three separate runways: one is ten thousand feet long, one is eleven thousand feet long, one is fourteen thousand feet long. To the left of the runways is a plane with 25 tons of cargo. The plane weights 275 tons.

Answer 4

Take off depends on airspeed, not ground speed. Taking off into a 50 mph headwind will have the plane lift off at a slower ground speed that taking off on a "no-wind" day.

Answer 5

You must have short term memory loss. Didn't get the right answer the first time you asked it?
