Boeing had just transitioned their FQIS from lbs to kgs (aircraft fuel is always weighed, volume changes with temperature). The flight crew hadn't had enough familiarisation and miscalculated.
All aircraft now calculate fuel usage in SI units.

- sokoloff 10y ago> aircraft fuel is always weighed Jet fuel is typically planned by weight. Avgas is typically planned by volume. In general aviation, both are typically priced and sold by volume. > All aircraft now calculate fuel usage in SI units. All 3 of my aircraft track/calculate fuel usage in imperial units. Likewise, everyone I know in US general aviation also still uses imperial units (lbs, lbs/hr, gallons, gal/hr).
- kwhitefoot 10y agoI wish people would stop saying imperial when they mean US Customary! An imperial gallon is about 4.5 litre while a US Customary gallon is about 3.8 litre.
- sokoloff 10y agoFair point. Thanks for the correction!
- sitharus 10y agoFair points, I was speaking to commercial aviation.
