It doesn't say it's for the same number of passengers, equivalent travel time and distance traveled.

  Fuel use is generally measured per distance traveled, so that part is implicit in the claim. The passenger capacity is talked about in the next paragraph: > What’s more, the Flying-V will carry the same number of passengers – 314 in the standard configuration – and the same volume of cargo, 160m3.

    I thought, specific to aviation, fuel efficiency was measured as a rate of time / power? https://en.wikipedia.org/wiki/Fuel_economy_in_aircraft#Propulsive_efficiency https://en.wikipedia.org/wiki/Fuel_economy_in_aircraft#Propu...

      Hmm... I've never heard of anyone mean thermodynamic efficiency when talking about fuel efficiency of a vehicle. Maybe people who design aircraft engines do? See e.g: https://en.wikipedia.org/wiki/Energy_efficiency_in_transpor https://en.wikipedia.org/wiki/Energy_efficiency_in_transpor > The energy efficiency in transport is the useful travelled distance, of passengers, goods or any type of load; divided by the total energy put into the transport propulsion means.

        Ah, seems like then it's possibly a bit of column A and a bit of column B. I'll defer to you on the correction though, I was merely speaking from third-hand/watercooler type discussions about aviation as someone who is just a passive enthusiast of airplanes.
