we'll see about CX's profit at the end of our financial year. Not only are the company quite good at figuring out A/C perf factors they are good at spinning the books.
I did ask to be corrected about the Beluga.
so: lets take 13 hrs then
2 777-300ER's burn about an average of 8 ( conservative ) tonnes a hour so FUEL burn 208 tonnes
Load of 600 plus 71 tonnes cargo ( 346 kg per pax )
1 A380 burn about 170 tonnes
Load of 489 plus zero cargo ( 347 kg per pax )
Which is better? depends on how much the landing and overflight charges are and how much revenue you get from freight. ( a bloody lot )
Interesting.
the calculations for the 777-300ER were:
MZFW 237.6
basic wt 172.0
Payload available 65.6 tonnes
301 Pax @ 100 kg = 30.1
Therefore Cargo could be up to 35.5 and the old girl would just be below
MTOW and would climb like an angel, fly smooth as silk and land like a fairies fart.
