Working out fuel quantity

Hey folks!! I was wondering if anyone knew how to calculate the fuel quantity roughly accurate in the 767 because everytime I put in ZFW, it says invalid entry.  So maybe the ZFW and fuel onboard doesn't make sense? Hope someone can help! Cheers.

Welcome, lucasgozzard.  Smiley
Is it possible that you are mixing up the definition of ZFW? This would lead you to wrong numbers and the FMC to define those wrong values as invalid entries then.
The ZFW is your empty weight + passenger and payload (usually summarized as "payload" in FSX).

Maybe this tutorial can help you too. http://www.captainsim.org/yabb2/YaBB.pl?num=1220997876

The ZFW, or Zero Fuel Weight, is the weight of the plane itself (empty weight) plus the payload (cargo+pax).

The ZFW is put into the FMC as a XXX.X number, and is abbreviated by hundreds, SO,

empty weight (these are NOT real numbers, just examples) is 145,334LBS

payload is 32,029LBS, the total weight without fuel would be 177,363. Now, this would be put in as 177.4. You round up to the nearest hundred, and that becomes the number in the decimal place.

When the FMC yhas the ZFW, the fuel is automatically calculated, as well as a bunch of other valuable performance info.


I hope that helps!
