Hi Trackdiamond, I ran a plan using our 7X, which is a 14 pax model, at M0.81.
As doctor bombay says, the MTOW is 70000lbs and the fuel on board is the maximum 30700lbs.
Flight time 9:20, airways distance 4750NM.
Initial FL350, then climbing after an hour to FL370, then FL390, then 1.5 hours to FL410, then FL450 about 3 hours before arrival.
Total fuel burn 24400lbs, and fuel remaining on arrival is 6100lbs.
Not sure about the weights you gave as there seems to be some confusion, but your ETE in particular is way off (by 3 hours). Airways distance is about right. You might be able to get to FL470 for the last couple of hours but the "average" flight level is FL410.
The route looks like this:
Obviously the route hasn't been checked for permissions etc. and alternatives are quite scarce in western China, so even with e.g. 120min at 440kts you might have to add some ADD EROPS fuel. (luckily you have plenty spare)
Hope this helps!
