Which aircraft gets better fuel consumption, the A330-200 or 767-400?

B764: 0.03572601454375
A332: 0.0463......

Looks like the A332 burns more fuel to carry a single pax 1 kilometre.

The 332 does not have as good fuel burn as the 764 although I would certainly not agree with Pacific's figures.

A 30% higher fuel burn is ridiculous.

Cheers,

I took the figures off Boeing and Airbus' sites! Below is how I got the figures!

Fuel Capacity/Range/Pax Capacity

I've just double checked the calculations again and it gives the same figures! I used the metric values.

Boeing: 91,380/10440/245
Airbus: 139,090/11,850/253

Everyone's welcome to check!

im not sure whether things are that easy. quite often, maximum performance is indicated with respect to each aspect regardless of the others. for example, a 767 may maximally travel 10440 km - but not with full load of pax and/or cargo, while an A330 might be able to do so. or the other way around. however, you'd need more specific figures to compare relative fuel burn.
by the way, i just surfed around SAS's tec-ops page (www.sasflightops.com). they tried to explain why they have chosen A330/40 to replace their b767. one reason was that the 767 could not carry both maximum pax and cargo to very long haul destinations while the a330 could.
however i'd be interested in reliable estimates of those beauties relative fuel burn.

The A330-200 has a higher MTOW, more range, carries more passengers and has more cargo space than the B764.

Calculating fuel burn is not as easy as you think, by the way.

You are not taking into account the range and payload of each aircraft. Try again. I did the calculation a week ago and found the A330 to be marginally ahead.

I've tried working out the efficiency considering weight for 20 mins and am totally confised. Will try agan in a few days when I have the time.

I tried calculating by the average weight which considers fuel burn. Boeing still seems to be better than Airbus but I'm no expert...

Boeing:0.000006264
Airbus:0.000008078
