I have problem with Fuel Flow, witch is around 5900-6600 pph at FL350 and at speed of 250 IAS and weight of 635000lbs while on RFP 742 at same conditions the fuel flow is 4500 pph. I know that the 741 hawe shorter range than 742 but with smaller fuel capacity and higher FF i dont have range of 4500nm, and second problem is unusual high pitch at FL350.
