CX251's (777) traffic load the other night was a little over 47,000kg of which 18,700kg was freight it was full with 275pax. (12,000kg traffic load available, this plus the fuel to carry it results in MTOW).
CX255 (744) just over 48,000kg traffic load of which 12,200kg's of freight, also full 358pax. (4,000kg under MZFW)
I asked the guys to create a flight plan for a -8F carrying 65,000kg. (35,000kg below -8I MZFW) I picked 65,000kg as both CX251 & 255 flight plans were based on a initial traffic load of close to 43,000kg the extra 22,000kg is to simulate seats and galleys in the -8F as the pax and freighter 744s differ by around >20,000kg, 25,000 for a -8I is probably more realistic now I've had a closer look.
In regards to fuel the interesting figures were, all based on around 43T of traffic.
744 CORR LDG 543
777 CORR LDG 386
748 CORR LDG 390
It would have been interesting to add that extra 12,000kg to the 777 & 748 flight plans and see what the new CORR RAMP/LNDG figures were.
So the question is can an A380 carry two 777s? or 550pax / 94T of traffic load of which 37,400kg is freight with a spare 24T traffic available? I can't see much hold space being available for 37.4T of freight, perhaps the space wasn't even available for the extra 12T on the 777?
I'm guessing the A380 would hit MLW issues like the A330/340 does, its max freight load would be around 20T operating to LHR, but as said is the space available?
