I calculate my fuel for a 4500nm with a B777-300 flight as follows:
4500nm/480knts = 9.375 hrs x 22,000lbs = 206,250lbs x 1.08 = 222,750lbs and depending on the airport I'll add taxi fuel according to EST. taxi time.
So I will use 222,300lbs + taxi fuel to complete a 4500nm trip.
The 22,000lbs is fuel consumption per engine per hr. (11,000 x 2).
The 1.08 is used as my reserve fuel, usually 45 min. worth. (16,500)
Are these calculations correct? I usually arrive at my destination with about 20,000lbs in the tank when landing.
I think that the fuel calculations given in FS are not realistic so I compute my own for each trip.
How do you calculate fuel and cruise level for your trips?

I do mine a bit simpler than that
I do the Route-Planner, see what i need then add on about 50% extra.
Usually get it about right

While nowhere near exact, if we use 121 flag rules, and the figure that you have provided, I estimate a minimum release fuel of 225,000 pounds.

Yeah, it doesn't seem to be perfectaly accurate. On a different note, according to
FS the Learjet 45 flies 2200NM. maximum. I managed to fly it just over 5000NM(No joke) non stop, that being with a 70pounds light pilot and no pax or baggage, and at a little bit higher altitudes. Does it really make such a difference?i can't imagine so, in real life i mean.
