530F, max continuous power, 85 degrees, 1250 above sea level burns 34.5 gallons per hour. I did not look at speed to do Nick's calculation. Putting around at 110 knots, same ambient temp, burns 30.5 gallons per hour. Fuel burn rates based upon fuel flow meter.
Nick is as usual correct plus I beleive you need to add limits. An E model when it is 120 degrees out with a C20R may have less range per gallon at certain operating limits simply because the turbine temps out with a high burn rate whereas an F model at 120 degrees with a C30 will not temp out and the result is you can actually get more range per gallon. So I would guess in models with different engine options, differnt engines in the models will yield different fuel consumption per distance.
I apologize for gallons versus Kg or Lbs per hour as the fuel truck delivers fuel in gallons and my brain can not on a part time basis convert to Lbs without occasional errors so it is easier and safer......simply to stay in gallons.
