Quantity goes to the float switches when full, then you will have the above answer that will go into computations to tell you that you will be heavier in winter and lighter in summer. And one guy telling you that he flies 4650 AIR MILES with its bird....
Dassault planes are flying like the book if they are flown like the book says.
QUALITY of fuel is far more important than its temperature, and (except when bags or pax were SUPER heavy, and not weighted) I flew the 2000, the 900 and the GLEX with their numbers on OFP, even if leaving the ground with 1000 to 2000 less than indicated required, upon arrival, numbers are matching.
But i do agree with everything written above... in a perfect world of entropy and exergy..
