Empty Weight A recent edit revised the empty weight to 12000 kg citing a EF world mag that quoted a Zero Fuel Weight or ZFW It is my understanding that this is not only by definition not the same as empty weight or operational empty weight or Manufacturer s empty weight but dependent on the configuration being considered My guess is that 12 t is rounded down from the weight with some AAMs what 6 2 say as quoted in the article That s the best I can think of for now but the most important thing is that the 12000 kg doesn t even claim to be the empty weight that we re trying to quote Adding a Air Air Typical ZFW figure would be fine by me of course it s all very interesting I have made it 11150 because that s what Janes says Elsewhere on the Eurofighter com site it says 11000 kg so I for my own benefit make the assumption until a better one arrives that 11000 is the MEW and 11150 is the OEW that is plus pilot various oil and hydraulic fluid and so on If someone knows better that s great please enlighten me but the 12000 kg figure isn t right I also changed the conversion to pounds which ironically made the pounds number go UP from where it had been and not DOWN this is just silly I have used the formula 1 lb 0 454 kg so that s good to the nearest gram Again if someone wants to look up better that s awesome but this is from my reasonably effective memory I haven t yet checked the other conversions
