With all the information on the internet, there seems there to be no website that lists aircraft's fuel burn numbers! Does anyone have that information?

Also, out of curiosity, do regional jet aircraft burn more gallons per seat than turboprops? How much more fuel does a 717 burn vs. a CRJ?


Don't bring up the NW DC9's unless you have to!

If you want anything better than vague answers, you have to specify: fuel burn at what speed, at what altitude, at what temperature, at what weight, with which engine. But it's true, even if you do specify all that you probably won't get the straight dope.

RJs burn twice the fuel/seat hour as a Prop with about the same speed/time on flights under 2 hours!!!!

B707 avg fuel consumption...1840 US Gal/Hr

L1011 avg fuel consumption....2680 US Gal/Hr

Others I have in the file.

The numbers above are considering climb to altitude, and a six hour cruise at normal speed...B707, M.82...L1011, M.86

Fuel burn varies too much with temperature and altitude to just have one number. Even a 172 has a whole range of fuel burns for various altitudes, temperatures and power settings.

Aircraft use pounds per hour, not gallons per hours. Capacity changes with temp... weight never does.

Big version: Width: 889 Height: 630 File size: 98kb


This is a chart of relative fuel burn for large widebody airliners. The sector length is 6000 nm. The payload is 95 kg times the area of the cabin in square meters (i.e. 1 pax / m2). The 773ER is taken as 100%, and burns 3100 gal/hr.

The other planes don't all cruise at the same speed as the 773ER so a better gauge is fuel burn per passenger mile, which is what is shown in the chart.

It's highly proprietary. As noted in prior replies, actual fuel burn is very sensitive to a whole bunch of factors (environmental, procedural, and technical). The Flight Management Computers on all current-generation airliners have very accurate models for fuel burn so this information is known, it's just not released because the people that have it have spent a lot of time and money developing it and they're not going to give it away for free.

At FL360 today, in the mighty 145 we were burning about 2400pph. MFD was showing about 430kts true. Had a nice little 80kt tailwind get us from ORD to GSO in about 1:20.
