Fuel Burn rates - fixed wing

I am looking to establish the fuel burn rates per hour (approx) and was hoping someone with more knowledge than I could assist with the figures. The aircraft I am looking for are as follows:

737
757
777
A320
A319
Bae146
Saab 2000
328
ATR42/72
CRJ200

Any help would be appreciated.

Cheers

At what altitude/speed/weight/temp ?

Rather general question there!

Hmmmmm, all the planes that go into Newcastle me thinks. We used 13 tonnes in a little over 4 hours during training a few months ago but that's nothing compared to all the cows farting in Australia!

Sorry to dissapoint you alibaba - theres nothing quite as underhand going on believe me.

I am a broker with a ppl and was after the figures for a piece of work I have on the go and its nothing to do with journos.

I am only after approx figures and have bizjet figures from the BBGA handbook - e.g. 1200 Lb/h for a 125, 2853 for a Global - but i cant get the larger stuff.

For info, the BBGA assume 75% of power at optimum altitude.

Any help appreciated

B777-200 about 7000 Kg/Hr with a good load and at mid weight between MTOW and MLW. B777-300 about 7500 Kg/Hr in the same circumstances.

RR powered 757:

At FL370 using long range cruise:

90000kg = 1600kg/eng/hour
60000kg = 1200kg/eng/hour

JT8s on a 737-200 :)

At FL330 using LRC:

45000kg = 1200kg/eng/hour
34000kg = 850kg/eng/hour

Thanks to everyone for the info.

I have come acorss the following info from other sources, can anyone confirm if these look anywhere near close?

Boeing 767-300ER Cons : 4000 kg per hour
Boeing 777-200ER Cons : 5500 KG per hour
Boeing 757-300 Cons : 3000 KG pe hour

Airbus 330-200 : 6000 kg PH
Airbus 310-300 & 300-600R : 5000 kg PH

ATR 42-3xx approx. 600 kg/h (both engines)
ATR 72-2xx approx. 700 kg/h (both engines)

And yes it flies with the fuel flow of an A320 in idle. :)

A320, FL mid-upper 300's, M0.78, with about 150 pax: 2300-2400 kg per hour.
BAe146, FL280, M0.65 about 70 pax, about 2000-2200 kg per hour. At M0.7 about 2400kg.
Bae 146 burns more overall though on a comparable distance sector due to very slow to reach an efficient altitude and takes much longer to cover same distance. And with half the pax :eek:

I am trying to convince a young friend in USA who wants to create an airline to go with an ATR rather than an EMB-120 Brazillia.... Anybody know the Brazillia's fuel flow please ?
