A fuel quantity crosscheck has to be done each sector and has to be documented in the fuel part of the ACARS journey log (we dont have paper journey logs). The max allowable difference between calculated and indicated fuel is the higher of either 500kgs of fuel or 3% of the indicated fuel. Fuel density should preferrably be provided by the supplier, if that is unavailable a conversion table based on fuel temperature (temperature provided by the supplier) or 0.8 as standard value.
