How much fuel does a large jet aeroplane use during take-off ?

Question

For example, Jumbo Jet. To get from the ground to, say, 1,000 feet, 5,000 feet, etc and to cruising altitude of 35,000 feet. How much fuel used to get to each level, and how much as a percentage of the full fuel load ?

Answer 1

747 running on GE engines can use up to 32000 lbs of fuel per hour on each engine at normal range of takeoff settings

initial climb speed of a 747 is 1800 to 2400 feet per minute depending on load

777's engines for some reason are more greedy at takeoff, maybe its the high bypass ratio but anyways, they drink at a rate of 50000lbs per hour, max, at normal range of takeoff settings

initial climb speed varies, but probably like the 747, is around 1800 to 2400 feet/min.

jumbo airbuses are slightly more efficient due to the smaller pratt n' Witney engines, but it probably similar

getting to an altitude of 35K is harder to say because pilots may step climb, may climb faster or slower depending on ATC, too many variables for me to give you a figure. but for sure, aircraft are not at takeoff power setting all the way up to their cruising altitude.

Answer 2

It depends on how heavily loaded the aircraft is, what the winds are like, air temperature and pressure, airport altitude, and other things.
