Cruise Hour 1: 12000kg
Hour 2: 11500 kg
Hour 3: 11000kg
Hour 4: 10500kg
Hour 5: 10250kg

Not flown 744 P&W but RR, IIRC, ballpark 10T/hr.
Lowest we ever landed with was 6T :suspect:

We crossed - eckhard is probably more accurate.

[eckhard]

5.8T for me!

My very rough ball park figure, brakes off to chocks in was 11 tons per hour. 13 hour flight, 143 tons, or thereabouts, it is really only good for a check against gross error. My off the cuff answer would be 55 tons.

Yes, 11T/hr is a good figure for gross boo-boo protection when flight planning B744 RR. Add another 11T for start, taxi, T/O and CLB. A bit less for the GE powered ER.
