Fuel Burn
 

Just curious....

Whats the usual fuel burn on the various Regional Aircraft out there? Primarily I am wondering about RJ's.

Does anyone have that info? or know of a website with that information?

My fuel burn today from BWI to CVG was around 4000 lbs. Ive had flights where you burn a lot >8000 lbs (CVG-IAD) and small amounts depending on the flight time/altitude/power settings. At cruise thrust I'd say we average about 1200-1600 lbs/hr per engine...

the ERJ's burn about 2200 to 3000 lbs an hour at cruise depending on your alt, speed, and temp.

Speed, altitude, ISA deviation, weight, and a few more factors all decide what your fuel-burn will be, but for a 50-seat RJ I would say at M.74 at FL370 you're looking at roughly 1200 pph/per side. In the 70+ seat range, add a couple hundred pounds to that figure. Those are my typical numbers. Your results may vary.

I care to remember the other day on a fairly long leg in the CRJ200 that at FL330 ISA deviation almost 0, MACH .74 and a full load we were burning right about 1300 lbs a piece. In the lower to mid 20's the burn is about 1450 lbs a piece. Also worn engines burn up to 14% more as far as I've seen. The ohter day we had an engine that was ready to be overhauled (could tell by the FF correction of 14%, spooling time, and ITT higher than normal). Also you burn about 3500-4000 lbs the first hour. A 15 min taxi is about 200lbs. It takes about 300lbs to shoot an instrument aproach with normal vectoring.

at most altitudes we fly (above 290) the 170 burns between 1800 and 1900lbs/hr/side.

we generally block anywhere from 2200lbs burn for short legs (IND-ORD short) up to 12000lbs burn (IAD-AUS or ORD-ABQ)

Ouch...thats a lot of fuel to burn considering the larger RJ's burn a couple hundred pph/side less, even on a bad day.

Doesn't really answer the question but....
 

The DC-8 we fly (CFM-56-2-C-1) burns between 11,000 -12,000 pounds per hour at .84 in the 3 zeroes. (2800-3200pph per). Higher in the mid to high 20's. Long Range Cruise brings it down to 10,000 if not heavy. <g>

Yeah, but they have real overhead bins.

It's too bad that Mainline (insert your choice here) has shown time and again that they really don't care for comfort...It's fuel they are worried about - and the E-Jets, though awesome to catch a ride in, are guzzlers in comparison to the RJ's.
