Ok, here's the scoop, I'm doing a project right now in school for my multimedia class, I will spare you the details, but I need every single piece of information known to man about the 737 NG and the A320, since they are quite comparable. Some of you may turn this into an all-out A vs. B war, but please, only info. no personal opinions please. I really want an A+ on this project, and I know, if all of you came together with lots of technichal info, but put it into layman's terms so my classmates will understand it, I would be very thankful.

Thanks for any info, I really will appreciate it. I need more info than what A.net supplies.

The manufactures' websites and this site's very own data section should be very helpful.

What does the project involve? Do you have to give a class presentation? Is anyone else in the class or your teacher very knowledgable about aviation? If not, you'll be able to half-ass it and get away with it. I'm kind of curious how 737s and A320s relate to your multimedia class. What is the specific assignment?

For a start, www.Airbus.com and www.Boeing.com will have useful info about these short haul twin jets.

737NG is still based on a design that first flew in 1967, albeit very heavily updated. The slowest seller in the 737NG family is the -600, whilst the -700 and -800 continue to sell well. The -900 is the largest family member and capacity is not far off the 757-200 in some US domestic configs. Uprated GE CF6 engines power the range. This NG family is the Boeing answer to the A320 family. The older 300/400/500 models just didn't cut it compared to the baby buses. Boeing lost valuable sales with the likes of United because the 737 range of the late 80's and early 90's just wasn't as good as the A320, both in terms of technology and economy. The 737 has always been a good bird though.

The A320 family comprises of these models:
A319 (Smallest family member, similar capacity to 736)
A320 (The original design, similar capacity to 738)
A321 (Biggest version, compares well to 739/752)

All three of the above are powered by either GE CF6 ot IAE V2500 engines.

The forthcoming A318 is based on the A320 family, but is shorter than the 111ft long A319 and has different powerplants, P&W 2000 being one of the options.

Yeah, like "Both are smaller than the 747 which is the only aircraft you´ve ever heard of. Yet, there´s a helluva lotta people on ´em.

BTW, the 319 would be more similar to the 737-700, capacity-wise, while the 737-600´s rival would be the 318.
And the 737-900 is no real contender for the 321 (again, only capacity-wise) because the latter has a max capacity of 220 pax while the former is stuck at 189 due to missing emergency exits.

Anyone already advised you to have a look at this site´s Aircraft Data & History section?

757man,

The 737NG is powered by CFM International CFM56-7 engines, the A32X by the CFM56-5 or IAE V2500. The CF6 is a much larger engine, and is (among others) used on the 747, 767, MD-11, DC-10, A300, A310 and A330.

uhhhh 757man... no 737 or A320 is powered by CF6s
(which powers some 747s/DC-10s/767s/A300s/
A310s/etc)...
the 737-600/700/800/900 is powered by CFMI CFM56-7 turbofans and the A319/320/321 has a choice of CFMI CFM56-5s or IAe V2500 engines. The A318 will also have CFM56s but also the new PW6000 engine.

Now then, comparison: (note when i reffer to 737 i reffer to the 737NG, not necesarilly all 737s)

The A320 has a wider cabin than the 737 and a higher cruise speed. The 737 is slightly cheaper. The 737 can be ETOPS certified. The A320 is full fly-by-wire, the 737 is not. The A320 has outsold the 737 outside the US and about broken even inside the US (A320 got UA, US, AW, NW. 737NG got AA, CO, DL, SW, AS).
As mentioned above the A320 comes with an engine option, the IAe gaining orders because it has better FOD rates and lower fuel burn, though the CFM56 is cheaper to maintain.
The A320 sits higher up than the 737. The 737 uses less runway in most conditions for a similar stage length.
Safety records are better for the 737, but are statistically irrelevant at this point because the A320 is 6 times the age of the 737NG (compared to all 737s, the A320 comes out about the same in terms of accident rate).
Well i think thats about all the authoritative true facts i can give without getting into personal opinion...

By range A321 also couldn't be compared with B752. B752 has farer range. I know, it is not real sometimes, but by original capacity, it would go so:
B736-A318
B737-A319
B738-A320
B739-A321
Some people compares A318 also with 717, but A318 has longer range, 717 is primarly short range airliner with low turnaround times.

Good info so far, I'll have to print it all out and the info from the websites. Since someone asked, I'll tell ya the details. My multimedia class utilizes a program under the Microsoft Office XP family known as Power Point. This program allows you to make detailed slide presentations with customized animation and the like. We have this assignment, which was to compare and contrast different things using this program, and having graphics, charts, tables, diagrams, and so forth. Many kids picked candies or colas, or even animals. I picked aviation, since I knew no one would have any clue to this, so they'll be too sruprised by the big words and fancy numbers (i.e. IAE V2500, or CFM-56, those types of engines would confuse anyone in my class) so they'll not know what I'm talking about and my teacher will have to give me an A. We then individually have to present these, and we use a projector for those. No one in my class knows about aviation, so I could do a half-ass job, but I'll get a half-ass grade too, since these have to be detailed.

Do you need some technical info regarding the ground handling, too?

All 737s have to be loaded manually (piece by piece) whereas all Minibuses (except the soon-to-come A318) are able to carry specially designed, so-called AKH-containers, A319 can carry 4&1/2, two in the fwd and 2&1/2 in the aft cpt, A320 can carry 7 containers, 3 fwd and 4 aft, A321 can carry 10 containers, 5 fwd and 5 aft. Airbuses also can come in the non-container version, which is - unfortumnately - very popular with the charter carriers, or they can be in a mixed version, with containers in the rear hold only and a plain fwd compartment.
A319s (and some 321s) have no access door for the rearmost cpt, called cpt 5, which is usually for crew bags and LMC-items.
A321 is the only a/c (as far as I know) that has only one service-pipe for an airstarter but requires the power of two units for an engine start. Therefore you need a Y-shaped adapter.

"The A320 has a wider cabin than the 737 and a higher cruise speed. The 737 is slightly cheaper."

Although the A320 has a slightly higher cruise speed, the 737NG can cruise at a higher altitude (Above 40,000ft I believe). I don't think the 737NG is cheaper either. Also, the 737 is the most popular aircraft to date, with the most sales.

The 737NG has a higher econ cruise speed than the A320, at M0.785, vs M0.78. Both have a max Mach speed of M0.82

However, the 737 Classics have an econ cruise of M0.745.

The operating ceiling for the A320 Series is FL391, for the 737 Classics FL370, and FL410 for the 737NGs.

Cheers,

Just a couple of hints for your project:

One way to do the comparison is to look at the cockpits of both aircrafts. Search for 737 & A320 flightdecks pictures on this website & you'll immediately see significant differencesbetween the two. Note that there are 3 different 737 cockpits and only 1 Airbus cockpit. Also look at the cockpits of other Airbusses & notice how similar they are. The Airbus company website provide the reasoning behind this cockpit philosophy

Next go to:
* http://www.mba-consulting.com/publications/market_focus_archives/jan2000.shtml
* http://www.bird.ch/bharms/asr_sh00.htm

There are some numbers there that you can convert into fancy Excel charts!

Have fun  Smile

Kcle, as ktliem@YVR said, it is a good idea to compare the cockpits.

All the 4 Airbus models of the A320 family have the same pilot rating, whereas in the 737 The 100 and 200 have a rating, the 300,400 and 500 have another rating and the NGs(600,700,800 and 900) have another rating. (basically 3 different cockpits)

The A320 family has a fly by wire technology cockpit, while this is absent in the 1st and 2nd generation 737s (i am not quite sure about the NGs).

I guess by now you can put up an impressive display before your class mates.  Smile/happy/getting dizzy

The A320 family has side stick controllers(more like your joy sticks) while the 737 have a conventional yoke for roll and pitch control.

The first 737-800 was the 2,906th 737 built. Klm was the European launch customer for the 737-900. I think these are the only things I know that haven't already been covered here...good luck on the assignment!

I was half asleep when I typed my initial reply to this post, and thank you for correcting me everyone. I do know that the CF6 powers larger types, it was a mere typing error. I did intend to say CFM56. Jeez, I've only flown on a 737 18 times, you'd think I'd know what engines powered it  Smile/happy/getting dizzy

Personally, I long for the days of the noisy old -200 version of the 737. JT8D - A classic engine if ever there was one.

Am I forgiven now?

There is one type rating for the 737 series airplanes. There is differences training required to fly the different versions, just as there is for the A320 series.

TDM,
Can one pilot have a rating for the -100/200's and the -300/400/500 and fly them all?

The A320 family is also much heavier than the 737-300/400/500 that they used to compete with (ex. A320 operating empty-- 92,113lb./737-400--75,555lb.) and therefore take a fuel burn penalty. But they also have more range than the 2nd generation 737's. The 737NG's, however, have comparable range to the baby busses. Just about everything else has been said.

Oh, btw, no the 737NG's are not FBW.

Not trying to be anal, but this is a school project. Students are expected to do their own research. A few pointers would be nice. But if people are spelling out all the details than it defeats the purpose of the project. Internet is a great source of information. I would suggest students don't abuse the kindness of the people in this group. Also, people should refrain from being too helpful. Just a thought. I know there are people who are always eager to show off what they know.  Wink/being sarcastic

Hey pal, just a bit of advice for you. Although, some of these guys may offer some great opinions. For a lot of them, thats all it is (no offense), but you want facts for a research paper. I know for a fact that past issues of Aviation Week magazine, Airliners magazine, Airliner World magazine, and Airways magazine (and probably some others) have all had some excellent articles on this topic. You might also want to try the Boeing and Airbus websites. Personally, I prefer the Boeing 737NG series, but I think honest research will point out to you that both of these aircraft are so great at what they do that neither has a significant lead over the other. They are pretty much an equal product (in performance) offered by different manufacturers.
