No pun intended:

too much!

(For more qualitative answers you would have to state a bit more things like e.g. weights)

Hi,

Like Hunter states, JT9 love fuel..
I fly 747 freighters with JT9 7R4G2

sorry not good with pounds, I am a metric man myself!

Taxi= 1T
@ heavy weights FF 14-16T an hour in cruise
@ medium weights FF 12-14T an hour in cruise
@ light weights FF 9-12T an hour in cruise

obviously the numbers above depend on actual weight and more importantly your optimum FL and howfar you fly below or above. flying to low really sucks the fuel.

trip at max weight from HKG-DXB with 100+T payload and MTOW Total fuel load 110-120T. depending on wind
I raw data check the total trip fuel/flight time=, should be around 12-13T an hour avarage

good luck

Hola Skystar -

Give me an air distance in NM and I will give you the trip burnoff (takeoff, climb, cruise, descent, landing) for the 747-200/300 with JT9D-7Q. I am with Aerolineas Argentinas, and have all the fuel dispatch figures if you want to, but I cannot give you my computer code to enter the program.

I need also the ZFW (tons/lbs payload, or number of passengers).
If you need liters or US gallons, a liter of Jet A-1 fuel is .815 kg per liter or 6.75 lbs per gallon at 15ºC temperature.
Be aware that there are 200/300 airplanes with 7 fuel tanks, 9 tanks and 10 tanks options.
Our planes (747-287) have the 833,000 lbs/377.842 kg max takeoff weight.
