Fuel Calc Help

[Dougal 165]

Hi GuysIf i'm not mistaken, the Max payload for still having FULL tanks is something like 147,000 lbs??? And, that this allows for Max fuel at: 361,700lbs.This being the case, anyone know what the APPROXIMATE max range might be, at std cruise? (ie - miles per gal type thing).I thought i should be able to do a non-stop KJFK-VHHH with that payload.Yeh, i know it's dumb question, and that i should be able work it out. Please don't shout at me, I'm not vey well:( Seriously, i'm not.Phil 'Dougal' Symonds

Phil,Looks to me like the max payload at max fuel is more like 97,000 pounds: 875,000 MTOW - 384,000 MAX FUEL CAPACITY (minus 2,000 taxi fuel) = 491,000 ZFW - 394,000 OEW = 97,000 PAYLOADIf you use the GE engines, you'll get roughly 6,670 miles in Long Range Cruise, or 6,560 in .85 mach cruise. That's a bit over 13 hours in the air.

How are you gettin 384,000lbs of fuel???? I must be missing the obvious here, but my 744F will only accept 361,700lbs.EDIT: Ah.... forgot to mention i'm F, not PAX. That''l be it. Never crossed my mind they were different.
