Hi guys,
Sorry to resurrect this year-old post, but my pilots are reporting some strange issues with fuel usage figures.
For example, a flight of just over an hour in a 757-200 recorded about 13000lbs fuel used, but the PIREP showed 28000kg (my local.config is setup for liquid units in kg).
Now, obviously that figure in kg is way off, so I looked at another PIREP log which showed take off fuel as
4737 lbs and landing with 2921 lbs, so 1816 lbs used. I looked at the kACARS code, which shows that if liquid unit is set to 2, then the conversion to kg is fuelused * .45359237, which in that case would work out as 823.72 kg. However, the PIREP showed 916.71kg !
Can someone shed some light on this issue please ? Is fuel usage definitely the take-off minus landing values, and if so, how come the total is not that of the formula in the code ?
Many thanks,
Nige
