Quoting BA (Thread starter): In a normal single-class layout, the CRJ-200 and ERJ-145 have just about 50-seats.

Hey Everyone,

I'm looking to see what your opinions are about the differences betwen the two aircraft, advantages and disadvantages etc. This is one grouping of aircraft I am very unfamiliar with and would like to know more...

Hopefully this doesnt turn into a B vs E post, but I just really want to know!

Thanks!

I think the CRJ200 flies comfortably but I dislike the seating and overall cabin configuration (I am sure the low windows will come up in this thread).

I like all Embraer products as a passenger (and less so as a support engineer). Although the 145 fuselage is tight, the 1-2 seating makes up for it in my view.

Best of all the RJs is the 170. (Don't bother noting that "It's not really an RJ". I'll trust the TC.)

I will tell you that after flying quite a lot of flights on CRJ-200 operated by Delta Connection, that passenger comfort is minimal. It's a neat little airplane, but my knees touched the feet in front of me, the seat was short, and the windows too low to look out off.

I made two trips on US Airways Express ERJ-145's and loved it. I had the "A" side, where I had a seat to myself and felt less claustrophobic.

Just my thoughts on the two airplanes. I'd give the edge to the ERJ on passenger comfort and looks.

Would anyone know if the ERJ 135/145 have leading edges unlike the CRJ 100/200? I've never been on a ERJ,but I don't have a problem with the CRJ 100/200 other than it would have been nice if the windows had been set higher. Speaking of the windows,can anyone explain why Bombardier did not lower the floor and raise the windows in the 100/200,unlike the 700/900? I find the seat pitch on the 100/200 to be acceptable and I'm 6'/182cm tall. My knees still have about 2" to spare,so I don't understand how it could be an issue as the 100/200 is never configured to more than 50 seats.

Well the CRJ has CF-34's and the ERJ has RR/Allisons  

I personally enjoy the CRJ200 more. Probably cuz I've flown on it 100times more the than the ERJ.

The CRJ provides more footroom than the ERJ, and seats are no different. If you are on the A side of an ERJ, you almost have to block the aisle with your legs, because there just is no place to put your feet.

Also the overhead bins are only on one side of an ERJ and both sides of a CRJ, hence more overhead space on the CRJ.

And the CF-34's are one of the most reliable engines out there. You never see any issues with them at all, and they are powerful and quiet, and have a very distinct sound.

The main difference is this one:

The CRJ is a derivate developed out of the CL600 Challenger business jet. Business jets are normally more complex constructions designed for less cycles than regional airliners. This results in higher operating costs of the CRJ over the ERJ, but also higher weights and solutions which are basically not so maintenance friendly.

The ERJ was developed as a regional. Therefore it's simple and straight forward, resulting in low weights, low maintenace costs and simple system desings. The ECJ "Legacy" made out of the ERJ is a business jet having the operational costs of a regional jet. The downside of the ECJ is, that the aircraft itself is more a "van" than a "Mercedes" and Embraer has really "no" experience at all how to service and support business jets.

You see, designwise they are quite the opposite, but both finally good products.

every aircraft has leading edges  

I've flown on both many, many times. They are both awesome A/C. But! The EMB has better window access. In the CRJ 200 You really have to hunch over to see out the window. However, in the new CRJ 700 series, this problem has been solved! They have lowered the floor an inch or so and raised the windows. Over all though, I think I still prefer the EMB with the 1-2 seating config. By the way, I really feel that you get much better service on these smaller A/C! Less people, more attention, and it always seems like you get more snacks and, at least on CO Express and Comair, they still have peanuts! That is something to rejoice about these days!   

Quoting 9252fly (Reply 3): can anyone explain why Bombardier did not lower the floor and raise the windows in the 100/200,unlike the 700/900?

If they lowered the floor, there would be no space for the langing gear.

Quoting JRadier (Reply 8): every aircraft has leading edges

I suspect he meant leading edge slats. The CRJ 100/200 does not have movable leading edges, but the 700 and 900 do. So he wanted to know if the ERJ had movable leading edges.

Quoting Ilikeyyc (Reply 10): So he wanted to know if the ERJ had movable leading edges

No, Embraer mounted those "Vortilons" on the wings, which take a good part of the work, slats would do but ways much cheaper, as there are no movable parts.
The vortilons are those four little (often yellow painted) fins, mounted on each wings leading edge of the ERJ.

I was browsing through pictures to see for myself and I wondered what those things were. Now I am curious how they work.

As already pointed out, every aircraft has leading edges. But I think the question was about leading edge slats, which the ERJ 135/140/145 do not have IIRC.

Quoting Ilikeyyc (Reply 12): I was browsing through pictures to see for myself and I wondered what those things were. Now I am curious how they work.

They work by smashing into the fueler's head while he's walking and distracted by something. Having been a former airline fueler, and having fueled both, the ERJ is a breeze...open one valve, pump gas...shut off at indicated amount...eat candy bar. CRJ is a game of jockeying switches and watching the gages roll back and forth till it finally satisfies itself. I hate the CRJ in that regard, but I think it's a far more attractive jet than the jungle jet.

Ouch! I believe that CRJ antennas have a similar purpose, except that they are there to gouge the backs of those who are crawling underneath the CRJ near the fwd avionics bay.

Quoting DeltaGuy (Reply 14): the ERJ is a breeze...open one valve, pump gas...shut off at indicated amount...eat candy bar.

It's even easier then that. Just set the requested fuel load on the fueling panel and then pump....eat candy bar...the plane shuts off the truck at the requested fuel load.

Quoting Ilikeyyc (Reply 12): Now I am curious how they work.

They better direct the airflow over the ailerons to make them more responsive.

Ilikeyyc:

I do believe, if my memory serves me rightly, if you go to the Canadair, Bombardier website they do indeed say that the floor for the CRJ 700 has been lowered and the windows raised to allow for better window viewing! If you have not noticed, there is a raised area on the floor under the seat area on the CRJ 200, not there on the CRJ 700! Hope this helps...FlyingRev.

As an A+P mechanic for ASA, I work exclusively on the CRJ 200 and my only experience with the 700 has been as a passenger and I prefer the 700 over the 200. Although I must admit that I am rather green on the 200, as I have only been working that aircraft for 4 months.

I know about the pressure floor below the floorboards, I see it on every aircraft that I work, and yes I have noticed the raised windows on the 700 (it puts less strain on my neck!) But I didn't know about the lowered floor until this thread. The CRJ 200 and 700 are about as common as the 737-200 and 737-700. The 700 has different engines and thrust reversers, better APU access, slats and even different landing gear- the lowered floor is now on my list.

I should have elaborated on my short post. My point is that the floor on the 200 couldn't be easily lowered because the landing gear, actuators, #3 hydraulic system and all the wires and hoses take up space below the pressure floor- and there is very little space on the 200 for those things.

I fly them both all the time, and I've never been comfortable on a CRJ. Even when I don't crane my neck to see something out the window, I can find no position in the seats that offers any comfort. Flying mostly UX, I find the cloth seats to actually be more comfortable than the leather, though calling either of them comfortable at all is quite misleading. I've never been uncomfortable on a ERJ, on the other hand. The overheads on either plane aren't big enough for any real carry-on bag, and my laptop fits under the seat on either plane, so I'm really not worried about the lack of overheads. It's nice to sit on the 1-side and have both a window and an aisle. Neither plane is remarkably quiet on the inside, although since both have tail-mounted engines, sitting forward provides the quietest ride. Either of them is better than flying for hours on a Dash-8 100, which would probably be the alternative (USAir Express...it's either that, or put up with the most boneheaded and rude airline workers in the world at PHL).

I haven't flown an ERJ aircraft ever, only CRJs. I haven't really found them to be as uncomfortable as most people say. I have only been on them for about an hour long flight, which may explain why, but for a short hop, I can't complain.

Quoting EMBQA (Reply 16): It's even easier then that. Just set the requested fuel load on the fueling panel and then pump....eat candy bar...the plane shuts off the truck at the requested fuel load.

I never did bother with auto mode...too much of a pain in the arse to go from 0-10,000lbs or whatever AE or CHQ wanted, when you could have been pumping the entire time. I just held (or tied off ) the deadman till it was 100 lbs short, let go...boom, requested amount + 30 or so for APU burn.

Or the fueler trying to take a shortcut to drop off the fuel slip

Leading edge slats are not found on either... but are on the new E170-195 series, and CRJ-700's on up.

Quoting Apodino (Reply 6): Also the overhead bins are only on one side of an ERJ and both sides of a CRJ, hence more overhead space on the CRJ.

But in either one of them the overheads are too small to fit anything other than a laptop, which you're probably going to want in flight anyways, or a woman's purse. I today used the overheads in a CO-Ex ERJ to shove my rain jacket into in case I had to use the hardstands at CLE (which I did) but can honestly say in my dozens and dozens of RJ legs that's the first use I ever had for the overhead.

Quoting Legacy135 (Reply 11): The vortilons are those four little (often yellow painted) fins, mounted on each wings leading edge of the ERJ.

So that's what they are? Awesome. But why are they yellow?

They're yellow, or in some cases red, so that the rampers see them before impacting their heads. They're apparently designed especially for maximum pain factor.

Quoting Apodino (Reply 6): Also the overhead bins are only on one side of an ERJ and both sides of a CRJ, hence more overhead space on the CRJ.

Yes, but there's one less person per row. And given gate checking bin space never seems to be a problem on the regionals.

Great to hear all of your responses.

Now I guess I mean when it comes to technical issues one has advantages over the other etc.

But I'm always hearing from people who prefer the CRJs about how cheap the Jungle Junk is...

Anyone know the price tags and the difference between the two?

Ilikeyyc

Makes sense, about the 200... I learn something all the time. Lowering the floor there would be a bit impossible! I often wondered why it was so on the 700 and not on the 200

Thanks,

The information I have seen (sorry, can't remember the link) points to very similar operating costs. The CRJ has better performance (less fuel cost) and the ERJ has better maintenance. Dispatch reliability also seems to be a very tight race, the ERJ started out poorly in comparison (since the CRJ had a couple years of service experience) then went on to surpass the CRJ - to which BBD apparently responded so they are pretty evenly matched.

The CRJ's used to command a premium in terms of purchasing price, but probably cost a lot more to build too. Now that the market for 50 seaters has collapsed, pricing is pretty moot (no one is selling).

Perhaps there are some pilots who have flown both who can chime in with their opinions as far as how the two compare regarding performance, avionics, flying characteristics, reliability, etc?

Everyone who has ever replaced a brake assy on both types knows the difference... 

Does the crj200 and erj145 have a autobraking system???anybody knows?

Neither one

But it could be because the airlines aren't willing to pay for it if the option is there
