For 895 on jul 15, the weight of the jet A fuel was figured at 6.73.
(that was on revision #5) the fuel was distributed as follows..( in LBS)
* indicated FULL load in tank.
2 RESV  8900*
1 MAIN  30150*
2 MAIN  84450*
CENTER  115100
HST     22000   (horizontal stabilizer)
3 MAIN  84450*
4 MAIN  30150*
3 RESV  8900*
       ------
Total   384100  (requested)
Actual  384500   (generated by ACARS at push @ 3:48, 400 extra by fueler)
Actual  381900   (at gear up @ 4:14)
DIF       2600    (used during taxi/tow) (taxi burn lbs/min 130)

It must have been towed because 26 min of taxi with engines = 3380lbs
burned.. Not to mention that the APU was most likely fired up no later
than 10 min before departure. And as I said earlier, this flight was
released for 14R with a Temp of 89 deg., Flaps 20, and Alt of 30.03 with a
planned tow to 14R.
It blocked in HKG with 28700.
