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_effi

  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.
