If max range not required cruise at 173kts. 3145 Gals usuable fuel. 10000 ft cruise 225 gph.
6500HP pulling 74,000lbs.. what was MAX cruise?
I have extrapolated a few figures from the Pilots Notes performance graphs using mid weight 70,000lb figures.
Max cruise 235kts TAS @ 270 gals per hour.
Max Range speed. 179kts TAS = 1.04 ANM/ Imp Gallon.
Lancman this might clarify your explaination
