744 fuel consumption per flight
 

A question that came to me after a recent flight:
How much fuel is burned by a 744 flying transpacific, e.g. LAX-MEL?
Of course there will be variation for weather, routing and countless other factors but I'm looking for a ballpark figure for a typical, average flight.

I'm rrying to calculate the incremental fuel burned hauling my 95kg across the ocean and wondering how Qantas could turn a profit on my fare with oil at US$50/bbl...

Ball Park Figures
 

Let's say 7000NAM, 386 tonnes BRW, 218 tonnes ZFW, 420 PAX, ISA.

Let's say M0.85 step cruise PAC rules for reserves, 200nm alt, 30min hold at 1500', engines/aircon normal, CF6-80C2B1F engines.

If the block burn average was 10.5 tonnes per hour 154 tonnes of fuel would go up in smoke; but if the block burn average was 11.5 tonnes per hour all reserves would be gone and not a skerrick left in the tanks!

PS: Not wishing to offend the man called Tullamarine, who would want to go to MEL without going to SYD first? (And no, I am not a cockroach). Unless it's the TELSTRA Dome to watch Aussie beat our two big offshore islands but I can watch the cricket on Channel 9 anyway.

Well silly you enicalyth 'coz NZ just beat Australia in the first of the one day series!!!

Yes, my ball park figure of fuel required was eleven tons an hour per hour of flight time, used only to check for gross error on a flight plan etc.

Fuel/pax/nm is approx. 0.05 kg

fuel flow??
 

Hmmm!!??

7000nam, 420pax, 0.05kg/pax/nm, no wind even. that's 147 tonnes in 14hrs 20mins or a block burn of 10.25 tonnes/hr. Please don't tell my management or I'm outta job!

Aw shucks BlueEagle, did I say which two offshore islands?

Minor point but:

I loathe mixed measurements. Shouldn't we keep it in pounds per passenger mile or kg per passenger kilometre? I recognize that there is no metric passenger however...

After an excellent landing you can use the airplane again!
