    There’s no way that miles to gallons of fuel conversion is correct is it? A little under 1 mile per gallon feels much higher fuel efficiency than I would have expected.

    Does anyone know about these things? Do these numbers just include fuel efficiency for cruising at altitude or do they account for the fuel required to lift a 30 tonne piece of metal and fiberglass 10 kilometers up into the air?

      My back of the envelope calculations give me around 500 gallons of fuel just to gain that kind of elevation (not taking into account anything but difference in potential energy). I assume most flights are less than 500 miles (I fucking hate that I had to do all of this in imperial) based on what I remember seeing from that Twitter account that used to post billionaire-tears’s private jet. In order for that fuel efficiency to be true cruising at that altitude would require basically no fuel or even negative fuel.

        I’m surprised they are using gallons at all…I believe the conventional unit for jet fuel consumption is pounds. I wonder if there might be a conversion issue with the data
