Fuel Burns CRJ vs 737-700

[Cheeta]

CRJ Cruise at 30,000 feet = 2500 Pounds per hour

737-700 Cruise at 30,000 = 4500 Pounds per hour

It certainly looks as if the 737 is more efficient if both planes are full of people


Throw in Domestic Airspace Issues..... Boeing looks pretty good!

Find the RASM and the CASM for the operator of any RJ....it will very slightly between regional airlines. Look for this info in an airlines 10K report.

For a quick and dirty rule of thumb for each aircraft:

737-700 about 4500 pph
CRJ about 3000 pph

Of course, it depends greatly on load, altitude, etc...

 

[BigPappa]

Just look at those links I put in and you'll get the idea!

 

[BigPappa]

CJR-200= 344 Gal./Hr v. B737-800= 784 Gal./Hr.

Again more than double fuel burn for the 737

 

[jetflier]

DC9 30 (100pax), 40(110 pax), 50(125 pax), burn FL350 5500pph .76M.

Pappa, I'm still standing by my numbers as good rules of thumb. I spent 6 years flying CRJs at Comair, so I'm pretty sure of the fuel burn we planned. I'd love to stay and debate the fuel burns you stated, but I have to go and fly my 737-700 to PHX.

 

[EatinRamen]

You also have to factor other costs per flight:

Landing fees are not necessarily double that of a CRJ to a 737. Probably you end up paying less per pax on a 737.

Ground crew/gate crew. You still need the same number of people to marshall an a/c, load and unload, board and offload. Again the 737 wins out in per pax costs.

Into plane fuel fee. Some fuel providers charge a fee just for showing up at the airplane. Again a 737 wins out here.

Then there's lease fees, insurance, mx. The RJ's costs are not necessarily 1/3 the cost of the 737. They are usually closer to 50% that of the 737, so when you spread these costs out per pax the 737 wins out.

Damn you're my hero..........

 

[BigPappa]

Mr. Bob while you fly your plane other professionals that specialize in facts and figures have already done the job of crunching the numbers for ya. Now that you did not fly the profiles at Comair and flawed those numbers is a separate topic!

Now don't burn too much gas cause your airline can't afford it!

 

[jhill]

What kind of fuel burns do these two aircraft have:

1. CRJ (50 seater)
2. 737-700


I'd be curious to see the difference ?

thanks

I do not have exact figures but.....

A maxed out CRJ-200 burns about 2800pph the first hour and 2500 the second. So for a two hour leg thats 106 pounds per pax.

A full 737-700 burns about 9500 pounds on that two hour flight or about 70#s per pax. Crew cost per pax are cheaper as well if you figure the 737 crew makes double what the rj crew makes which is not always the case.

 

[CoolSidePillow]

Do not forget about the price of putting your life in the hands of incompetent RJ pilots.

 

[mrebuck]

Remember...

You can be an airline pilot!

-15 days off per month

-free travel

-fly a 25 million dollar jet at mach .76

There's nothing like it!



WOW!

 

[Poahi]

so when you spread these costs out per pax the 737 wins out.

Shhhh. Don't tell management. You guys have actually figured out that a larger aircraft has lower per seat costs than a 50 seat RJ. When management finds out about this, it's going to be a real mess.... I guess it's a good thing these things were scoped out of the legacies contracts and it's funny, had management known this little secret, they would have never bought thousands of them.

I'd bet soon, we are going to see 747's flying between LAX and SAN.

 

[Bob_Sacamano]

Well, I don't deny that I'm damn heroic. But at least I've actually flown the planes these CFIs are talking about...

Damn you're my hero..........

 

[Bob_Sacamano]

Well, it's too bad you can't read, ******************************bag. I clearly said they were rough rules of thumb. And I flew the profiles as instructed in our FSM. Perhaps you'd like me to borrow a manual from someone from two airlines ago and get the precise numbers? Oh wait, that's right...I said it was a RULE OF THUMB.

As for burning too much gas, you've made a tremendous leap in (flawed) logic which totally exposes your gaping ignorance. While planning a fuel burn that's a RULE OF THUMB (there's that pesky phrase again), and by flying the company profiles, we almost always underburn. So please come back when you finally learn what the ******************** you're talking about.

Rookie...

Mr. Bob while you fly your plane other professionals that specialize in facts and figures have already done the job of crunching the numbers for ya. Now that you did not fly the profiles at Comair and flawed those numbers is a separate topic!

Now don't burn too much gas cause your airline can't afford it!

 

[BigPappa]

Mr. Bob you sir have serious issues. I have far more experience than you might assume. Before you call someone a rookie it might help if you actually know who you're talking to. Now bring me my drink mr. Baby Boeing pilot!

 

[Bob_Sacamano]

I'm "pouring" it right now. But I've heard you prefer it directly from the tap...

[Bob_Sacamano]

BTW, sold any gyros lately?

 

[BigPappa]

Bob,
Do you feel like I stepped on your toes, you poor thing! Now you have to be all defensive and vulgar because that is as much as you could handle. I send you up and steaming through te roof! Now that is funny to me. You blew.:laugh:

 

[Bob_Sacamano]

No, I certainly didn't blow. I just put you in your place for acting like you know everything, when you clearly don't.

As for the vulgarity, I looked at some of your posts. You've made TONS of one line slams to people, usually ending them with "eek" or you saying you're smashing their nuts with a hammer, along with lots of homosexual references. So I wanted to bring it down to your level, so you'd understand.

BTW, you didn't answer my gyro question. Did you get out of the gyro business when you upgraded?

So is this where I add my little :smash: , , :uzi: , or ?
