Bit low on taxi- more like 900kgs+. Rest sounds reasonable. Conversions........1000kgs.=1250 litres (at a specific gravity of 0.8) For extra marks, get the little blighter to give the Imperial gallons figure just to educate the Continentals in real units- at about 4.75(?) litres per Imp. Gallon (none of those short measure US Gallons allowed here please), it comes to about 260 gallons/tonne (I think). Fuel usually remaining after arrival at JFK for Reserves/Alternate 12,000 kgs (I wish). Now give him a calculator!
