400 CWT
"Freighters don't fly long enough legs to need the extra fuel. Freight operators would rather carry more payload than more fuel."
"The typical 747 freighter missions doesn't even use center tank fuel - wing fuel is all that's needed."
"While SMOC is technically correct that all -400s (and -8s) have a stab tank, the associated claptrap of pumps, fuel lines, seals, etc. is not insignificant in both cost and weight, so no reason to have it if you're not going to use it. Further, there are MEL implications - if something is INOP, - even optional systems - it needs to be fixed at some point per the MEL. So that provides even more incentive to simply get rid of the stab tank fuel system if you're not going to use it."
WHAAAAT?
