Question

What is the take off speed of a plane?( say a Boeing 747)?

Answer 1

All aircraft are different.

Answer 2

Depending upon aircraft weight, air temperature, air pressure, elevation, and wind speed, takeoff speed may vary.  I believe a safe speed to use as an average would be 155 knots (180 mph).

Answer 3

145-148 knots.

Answer 4

A 747-400 model takes off at around 175 knots thats around 324 kilometers/hour.

But if the aircraft is taking off into the wind the plane can take off at possibly 140 knots.

Answer 5

for single engine small aircraft such as a cessna 172, rotation speed is 55 knots.

for dual engined propellers planes such as a beechcraft baron, it is around 80 knots

for dual engined propeller commercial aircraft, it is much closer to 120 knots

for medium jet aircraft (737), it is around 138 knots

for heavy jet aircraft it is closer to 150 or 160 knots

for the 747 specifically, it is around 165 knots

(1 KNOT = 1.15155 MILES PER HOUR)

all figures dependent on weather, weight and airport altitude

Answer 6

depending the height

but 150-180 mph :)
