That was very interesting thing for CX aircraft changes sked from HKG-LAX by the Airbus A346 to B744 aircraft again. What is exactly will have planned going on on the Airbus A346 aircraft to SYD? Well, talk ya later!

I'm afraid it's bums on seats and the Airbus with only 288 in the winter (lower loads) with the strong headwinds is the more economical A/C, while the 400 in summer with a full load of 343-389 and weaker headwinds makes it the better A/C.

Boeing 767-300: My thoughts exactly! I can understand why they might not choose to use it for HKG LAX but what about HKG LHR which is sometimes operated by an A340-300? Isn't the A346 designed to be an efficient, ultra long-haul aircraft?

It appears that CX is on the way to choosing the 773ER, despite the additional engine type, for Euro-flights in the near future.... as opposed to A346. They'll be [idiotically] reluctant to fly a twin over the water however, so they'll probably work the two together.

I'm sure Cxflyboy can elaborate, but surely dispatching a twin over the high terrain between Hong Kong and Europe would be impossible due to single engine maximum operating altitudes at the high weights required for the route. A four engine aircraft only has to prove 3 engine operating altitudes.

I'm aware of twin certification, particulary as I fly the B767, however at max weight the single engine ceiling is still in the low twenties. The higher thrust to weight is mainly to meet second segment climb criteria. It is the Himalayan routes in Chinese airspace I am referring too, that being the most efficient at some times of the year. What percentage of Cathay's flights operate on these routes?
The Himalayan operational limit on a Boeing 747-400 is related to oxygen capacity southbound, with jumbos on L888 for example carrying extra oxygen in the passenger cabin. It can only be flown southbound as aircraft are too heavy northbound to maintain the LSALT engine out.

It is correct that SYD was always in the plan. The 744 carries 100 more pax than the A346, so they are not competing aircraft. The A346 however does carry a lot of freight and that is what they needed more of in Sydney.
I obviously don't have data for the 777-300ER. However for the 773 in our configuration, MTOW is 263tonnes. Our data for Engine INOP max alt shows at 300 tonnes up to ISA+10 we can maintain FL140. We don't use full TO rating at the moment, but if we did, I believe our MTOW would be around 300tonnes, or certainly towards it. At these weights we cannot clear some of the highest terrain on our European routes. We would definately use different routes, namely the more northern routes over Mongolia rather than the route south of that over Urumqi. Air France currently flies 772s HKG-CDG, but not sure which way they go, north or south.

I think the A333 that flies that route regularly is due for maintanence and the B747 that flies to SYD is also probably due to be retrofitted with the New Business Class, hence the aircrat swapping.
CX is still refurbishing their aircrafts with the new Business Class seats, hence there will always be confusion as to what aircraft flies where. And whenever each aircraft goes in the hanger, it disappears for a month and that void has to be filled out somehow by replacement aircraft. So a 346 that normally flies the long haul can take the flak for a semi-long haul flight for a while.
All the Airbus A340-300s will be refurbished by this year. The B747-400s are halfway done with the remaining 8 to be completed by Feb 04. So in the meantime, there will be plane charades!
