OK, I'll take the risk, but only if everybody agree we're in a Pub after several beers and tomorrow we're not flying.
With a cost index slightly below LRC and landing weight 60 tons, trip fuel 37 kgs per minute flight time.
To be corrected half a Kg per minute per ton, above-below 60 tons landing weight.
This is only trip fuel, of course.
OK, too many beers. Time to go!
