A380 arrival fuel Lax
Can anyone advise what is an average arrival fuel in Lax from Sydney
On a nice day with a close alternate like vegas.
about 1 hour?
And is so what is roughly 30min + 30min holding.
eg a 747-400 arrival weight 250t arrives 11t fuel 30min +30min at 1500ft

Can't tell you a 380 but 747 is typically around 14-15 tonnes. The reason is contingency build-up usually based on a depressurisation a couple of hours out of LAX and either return to PHTO or continue to KLAX at 14,000' and then 10,000'.
Depending on weight I'd assume a 380 is about 10% more.
Alternates for LAX are usually based on KONT rather than KLAS.

Ontario is the normal alternate - 9.6 tonnes including reserves. SFO is about 18 - 19 tonnes. 30 holding is 5t.

A380 doesn't use Vegas as an alternate, using Phoenix, Ontario or San Fran instead.
Fuel figures on arrival are similar to 744 as mentioned above. Contingency fuel can vary greatly depending on the route across the Pacific and distance from PHNL/PHTO and NSTU.

I think this one stems from a thread on the Fragrant Harbour forum ("Wide-bodies for CX?") where some posters claim that the A380 is particularly unsuitable for the HKG - North American routes. Quoting the QF SYD-LAX route, it's claimed that because of CP and Mandatory Fuel requirements, with the last suitable ERA being HNL (still a fair way to go), the A380 arrives in LAX with some "50T sloshing around in the tanks"!
Doubtless this is being pushed by the B747-8 camp!

I suggest that is a function of HKG regulations and the FAA Operations Spec., not the A380. I don't see why the B747-8, burdened by the same regulations, wouldn't produce equally uneconomic landed fuel.
Tootle pip!!
