What's the weight of 747-400?
toto
What fuel load can it carry?
What weight of payload can it carry?
I went to Boeing web site but I'm still not sure how these weights are
different.
Please tell me...

>From http://www.boeing.com/commercial/747-400/product.html, 398,780 lbs
is the typical operating empty weight. That's airframe with no fuel or
payload. The exact weight depends on the engines selected as well as
the interior fitments and other options.
>What fuel load can it carry?
It depends on which engine type the aircraft has and whether it has the
optional fuel tanks in the horizontal stabilizers. Boeing's page lists
fuel capacity in gallons, but I'm guessing you want weight. As a rule
of thumb, a gallon of Jet A weighs about 6.7 lbs. That's very rough as
it depends on temperature and exact fuel composition, but it's a decent
first approximation. Combining that with the Boeing data:
engine gallons lbs
------ ------- -------
PW4000 57,285 383,810
CF6-80C2 57,065 382,336
RB.211-524 57,285 383,810
>What weight of payload can it carry?
Fully optioned, maximum gross takeoff weight is 875,000 lbs. Taking out
the typical OEW and 383,810 lbs of fuel leaves 92,410 lbs of payload.
You can trade off some fuel for increased payload; AW&ST's Source Book
lists the cargo capacity of a 747-400 (passenger model) as 155,720 lbs.

OK, these aren't exact, and mostly from memory,, but here goes. All for
Cargo BTW. Max TOGW for a 400 is roughly 875,000 pounds. Max Zero Fuel
Weight is around 660,000 lbs. The Basic Operating Weight is somewher
earound 360,000 lbs. So, Figure a max payload of somewhere around
300,000 lbs. And a max fuel weight near 200,000 lbs...
Again, i don' work with many 744's (unfortunite, i love the planes). hope
this helps

It varies, but our freighters' BOW run around 158,000 Kg.
> What fuel load can it carry?
163,000 Kg
> What weight of payload can it carry?
Maximum TOGW is 396,900 Kg.
Max Zero-fuel weight is 288,000 Kg. That makes max payload about 128,000
Kg.
