Boeing is moving "far more aggressively" toward a 180-250 seat twin-aisle replacement for the 737, according to company insiders. It would continue production of the 737-800/900ER for airlines that still want the standard offering.

VP-Advanced 737 Product Development Mike Bair confirmed last week that a twin-aisle has been canvassed, a scenario first revealed by ATW in 2006 (ATW, June 2006). Separately, ATW has learned that Boeing will announce an all-new 737 replacement, to be named the 797, at or before the Paris Air Show commencing June 20. Bair’s comments regarding the replacement being a twin-aisle, which have not been denied by the company, came in an interview with Flightglobal.

The 180-seat twin-aisle concept has a fair amount of history. McDonnell Douglas developed a 180-seat twin-aisle concept in a 2-2-2 configuration in the early 1980s dubbed the DC-11. Delta Air Lines wanted to order 60 but MDC balked at the commitment, considering it too risky given the lack of interest from another US airline. The fuselage had a cross-section that was 22 in. wider than the 727/757, allowing for 17.7-in.-wide seats in doubles with two 18-in. aisles. In an all-economy layout at a 30-in. pitch, it could seat 214.

Using the latest technology at the time, including composite floor beams, control surfaces, nacelles, vertical and horizontal stabilizers and other primary structures, MDC predicted fuel consumption 10% better than the 757 with the same engine application—the JT10D-32 engine rated at 32,000 lb. thrust.

Boeing also floated the twin-aisle 180-seat concept in 1987—the year that Airbus rolled out its A320--with its 7J7 and showed a full cabin mockup at that year's Paris Air Show. It took the widebody concept further with a 181-in. cabin width that would permit 2-3-2 seating, 17-in.-wide seats and 18-in. aisles in coach. It is this cross-section that insiders at Boeing tell ATW the company is focused on.

The twin-aisle idea surfaced again in 2001 in two patents filed by Boeing under the heading "Twin-Aisle Small Airplane," with Mithra Sankrithi, a manager in Commercial Airplanes' product development, configuration and engineering analysis group, named as the inventor. The patents were submitted on Oct. 2, 2001, and approved in 2003 and 2004. One cabin sports a 2-3-2 configuration with Sankrithi claiming the new configuration could deliver "the comfort typically reserved for larger aircraft," while at the same time minimizing drag, weight penalties, fuel burn and "economic penalties." The fuselage cross-section for the 2-3-2 configuration is 200.7 in., fractionally wider than the 767's 198.03 in., and the design features a swept T-tail.

Interestingly, Sankrithi filed another patent last year with co-engineer Kevin Retz with the same T-tail twin-aisle under wing engine layout, which is similar to the configuration and layout of another McDonnell Douglas aircraft: The 1981 vintage 150-seat MDF100, which was to be built with Fokker on a 50/50 basis but didn't get off the drawing board.

The comment was made- I don't see how this is a 737 replacement - a 757 replacement yes- but w/180-220 seats how is that a -700 replacement??

Interesting idea though

Agreed. That will leave a gap in. 120-180 seat range. Will BA address that or will wn take a closer look at bombardier?

 

[LearLove]

I agree with the above. If it is true that the 737 replacement will be in the 180+ seat range then they (Boeing) have left the 100-150 seat market to Emb/Cndair/Sukohi/Mitsu.

Maybe the airline upper management got to Boeing and said, "hey abandon that market then let emb and company build the smaller jets so we can label them "express" and outsource the 100-150 seat range" - I wouldn't put it past them.

SWA - stay away from the design process PLEASE!!!!!!

Don't let SWA near the Boeing team in Paris unless you want to keep that dated 737 overhead panel... Thanks Herb!

 

[jws717]

I would assume Boeing is keeping plans on the 100 to 150 passenger market behind closed doors until Airbus commits to an A320 upgrade or replacement.

Or maybe after they ever figure out the 787 disaster.

 

[ACL65PILOT]

or maybe Boeing is going to give that to the C-Series.......

How much 737 time do you have?

 

[WalterSobchak]

Well, the 757's are getting pretty old.

Either Boeing sees the market shifting toward slightly higher capacity airframes with the operating costs of current 100-150 seat aircraft...or, they're considering conceding that market to Bombardier's and Embraer's of the world. I suppose they could offer a smaller variant at 140-150 seats...but, if the performance/costs are similar to/better than the 137-seat B73G with a higher capacity, why not just roll with the 200-seater?

Either way, imagine SWA's turn times if they had a twin-aisle with a 2-2-2 configuration and ample overhead bin storage. The slowest part is always the self-loading cargo.

Spot on.....unfortunately. :crying:

Let's just hope that Southwest doesn't get to give their opinions on the new flight deck. Guess what boys? Next Generation DOESN'T mean switches and knobs. Thanks for ruining it for everyone else on the "older" Next Generation 737-700s and -800s.

OK, who/what is that exactly on the tail?

 

[johnsonrod]

How much 737 time do you have?

80,000 hours. How much Space Shuttle time do you have dumba$$? I jumpseat on 737s all the time and they are ARCHAIC vs. the Airbus line and now newer aircraft like the E190 and soon-to-be C-Series. I know several 737NG pilots and they all say the systems are beyond basic. Nobody will dispute that the 737 program was set back by SWA and their demands. Sad but true.

 

[waveflyer]

Yeah- Swa has really held Boeing back. Bc it's all about the technology.... Not making money... SW has bought over 500 737s and the 73 is the most prolific airliner in the world. I think it survived us...

The kids call you "haters"
I take it as a compliment

Now, now. No need to call names. It was just a simple question.

Your lack of maturity is shining through.

Grow up.

It appears that Boeing is not having any problems selling NG's these days. I believe I read they just upped the production rate by a few more per month. That old, archaic airplane program seems to be doing just fine.

Gee, thanks for the advice Dad. It is well documented that SWA had a big say in the cockpit design of the 737NG. Honda Accords sell well too but I don't have a burning desire to drive one. You might be happy driving a basic Accord or an old Ford Taurus but I am not. The people I know who fly it aren't that impressed regardless of what the airline accountants say... Thanks for the 737 program sales update.
