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...
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.
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>
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.
