Zhuhai Airshow: China’s aircraft industry is gaining speed
The 10th Chinese airshow at Zhuhai opened today. It was a day with fewer announcements than expected from the usual suspects (Airbus, Boeing…) but the Chinese industry did not disappoint. China is now showing more and more of its coming might as a player on the aeronautics arena.
The most prominent displays at this show were on the military side, where China has two stealth aircraft projects flying (the large Chengdu canard J-20 and the smaller Shenyang J-31) while their canard Chengdu J-10 was flying the display circuits overhead (Figure 1).

All aircraft are of latest structural and aerodynamic design if not in engines and systems. This is a big difference to previous shows where the Russian Sukhoi and MIG aircraft and their local copies did the flying display until 2008. Since then everything has changed and now China and USA are the only countries in the world with two different stealth designs flying. USA has one in operation (F-22) and one close to (F-35) whereas China still has many years to go until they have their new aircraft operational. But it is significant that the old aeronautical behemoths Europe and Russia have none respective one (PAK-50) stealth fighter in flight test.
Odds and Ends: 787 donation; Alenia sues Bombardier over CSeries; 2016 777 delivery slots opening up
787 donation: The Boeing Co. handed over 787 test airplane #3 (ZA003) to the Museum of Flight Saturday in an elaborate ceremony marking an unprecedented donation of a modern airliner to an aviation museum.
Boeing 787 ZA003, which went on a world sales tour, was donated to Seattle’s Museum of Flight Nov. 8, 2014. The logos of customers bracket the #2 door. Photo by Leeham News and Comment. click to enlage.
To be sure, the donation was made possible by the fact that ZA003 (and 002 and 001) can’t be sold due to the massive rework necessary, and these three airplanes have been written off for more than $2bn. But this doesn’t make the event any less significant.

Introduction
Boeing is looking at a number of scenarios for its New Airplane Study (NAS) that would replace the 757 and 737, have ranges from 4,000nm-5,000nm, and carry as few passengers as 130 or as many as 240.
To cover this broad range of demands could require reverting back to the 1980s when Boeing simultaneously developed two airplanes serving very different missions, the 757 and 767, that shared cockpits and some other common elements.
Boeing faces some hard decisions in the coming years, as Airbus outflanks Boeing in the single-aisle sector with the A320neo family and its latest offering, the A321neoLR. Our analysis and sales figures show the 737 MAX falling further and further behind in market share as MAX 9 lags vis-à-vis the A321neo.
We spoke with Kourosh Hadi, director of product development at Boeing, during a break at a conference last week organized by the British American Business Council-Pacific Northwest, and covered this and a number of other topics.
Summary
- Boeing is studying a New Light Twin (NLT) and New Single Aisle (NSA) to replace the 757 and 737 airplanes.
- The tipping point between an efficient NSA and the NLT is around the passenger size of the 757-200.
- Boeing is evaluating materials, including metals and composites, for the NAS and the manufacturing process, which will also be a determining factor in the materials for the new airplane.
- Engine advances for the 777X’s GE9X are beyond the GEnx and CFM LEAP of today and could help drive the next new small engine technology.
- Although having a miniscule portion of the 100-150 seat market, Boeing today plans to continue participation in at least the 130 or 150 seat sector even as airplane size moves up every year.

Part 3 of 3
Introduction
In Part 2 of our three-part 757 Replacement analysis, we took a close look at Airbus’ new 97 tonne take-off weight A321neo, revealed in a world exclusive by Leeham News and Comment October 21. We analyzed the A321neoLR’s capabilities and limitations when compared to Boeing 757-200W and we saw that it could do the international flights that the 757-200 does with about 25% better efficiency. In this final Part 3, we will now compare the 757 and A321neoLR against what can be Boeing’s reaction, a clean sheet New Single Aisle, NSA, or New Light Twin Aisle, (NLT). First the conclusions from Part 2:
- When using the United Airlines-configured 757-200W international as benchmark, we came within seven seats of the 757 capacity for an A321neoLR. It covered the same range and had trip fuel costs that were 25% lower.
- The per seat fuel costs gave a 22% higher efficiency, which was within 2% of Airbus own figures.
- 737 MAX9 is not suitable for stretch to an international version, not because the wing is not good enough but because the MAX9 cannot bring the wing to an angle at take-off where it can work efficiently; the landing gear is too short.
Summary
For Part 3 we can summarize:
- A New Single Aisle (NSA) or New Light Twin (NLT) which would enter the market in 2025 would be sized at around 200 passengers with subsequent variants covering the 175-225 seat market, all numbers with OEM standard two-class seating. Figure 1 shows the fuselage cross sections we have used in our modelling of NSA and NLT to cover this market segment.

- In order to cover the market segment of the 737, A320 and 757 it would have a range in excess of 4,100nm. We will use 4100nm for our modeling to maximize the comparative efficiency information.
- Its efficiency would be higher than an A321neoLR, primarily due to better engines and a more modern wing.
- The New Light Twin (NLT) wins on comfort and ground turn-around time but pays with a larger fuselage cross section due to the extra aisle. This causes more drag and structural weight, net effect is a reduction in efficiency of around 2.5%.

Part 2 of 3
Introduction
In Part 2 of our three-part 757 Replacement analysis, we take a close look at Airbus’ new 97 tonnes take off weight A321neo, revealed by Leeham News and Comment October 21. We call the 97t airplane the A321neoLR (Long Range); Airbus has yet to name the aircraft, which it began showing to airlines last week.
We analyze the A321neoLR’s capabilities and limitations when compared to the aircraft it intends to replace, the Boeing 757-200W. We have chosen to do so using a real airline configuration as opposed to an OEM’s typical seating layout. By comparing the 757-200W and the A321neoLR over the route structure that United Airlines is using the 757 today, we can better see the characteristics of the A321neoLR and what operational consequences the differences between the types would mean for the airlines. Before we start, a short recap of Part 1 about the 757 and its replacement candidates. Here is what we found:
- the seating capacity of the A321 is within 10 seats of the 757-200 in a standard configuration; the 737 MAX9 is trailing with about 20 fewer seats.
- the myth about the strong engines of the 757 is just that, a myth.
- the good field performance of the 757 is coming from its wing more than any advantage on the engine side
- the A321neo and 737 MAX9 were hindered in their capability to replace the 757 for long and thin international routes by characteristics that can be changed. For the A321neo, this may be accomplished with rather modest changes to Max Take Off Weight (MTOW) and tankage. For the 737 MAX9, more elaborate changes to the wing and engines are required, both hard to do.

Summary, Part 2
- We will now look in detail on the changes Airbus is doing on the A321neoLR, what each change brings and any restrictions that remain.
- We will also detail why we think it will be harder for Boeing to match the A321neoLR with a 737 MAX9 development.
- We detail prime, present 757W long-thin routes.
- We present 757W international, A321neoLR and 737 MAX9 “long range” configurations.
- We provide economic comparisons such as Payload-Range charts and Fuel consumption per trip and per seat diagrams.
In the final Part 3, will look at Boeing’s alternative to an A321neoLR, a clean sheet New Single Aisle (NSA) and a prospective Small Twin Aisle (STA) design and how much such an approach would surpass the A321neoLR on medium and long haul networks and when it could be available.
E-Jet, the project that shaped Embraer
By Bjorn Fehrm
Introduction
In a recent visit to Embraer in Brazil we got a thorough brief on the background and decision making around the E-Jet and E-Jet E2 programs. We have written about these programs before but we will now cover how they came about, what was the program objective when the decision was taken and how it panned out. Both programs have had and will have a profound influence not only on Embraer but the whole civil aviation segment between 70-150 seats. It is worth looking into how Embraer, once an also-ran in the regional market, rose to the top three spot in civil aviation after Airbus and Boeing and how EMB intends to stay there.
Summary
- American Airlines was part of changing history in regional jets, long before in single aisle.
- E-jet started as a product program and soon put Embraer on a steep learning curve how to support an E-jet in the market above 50 seat regional jets.
- Embraer today rates their support second only to Boeing and Airbus.
- The requirements for the mid-life update of their E-jet, the E2, is all about delivering a mature product. This has shaped all aspects of the program, from cooperation with suppliers to how testing and qualification is done.

A380neo becoming a reality

Introduction
We last looked at the Airbus A380 economics in February, when the airframer was promoting the giant airplane as a 525 seater. Since then, Airbus recast the airplane as a 555 seater. This changes the economics somewhat. Further, Airbus is floating an 11-abreast coach configuration vs the out-of-the-box 10 abreast.
Tim Clark, president of Emirates Airlines, continues to press for a re-engined A380. In our companion Assessment of the Very Large Aircraft market, consultant Michel Merluzeau believes Airbus will re-engine the airplane.
So do we.
It has been pretty clear to us that Airbus will do an A380neo. The question is when. Emirates’ Clark last month predicted the decision would be taken within six month. Our latest Market Intelligence says he will be right; we understand that Airbus is right now preparing for an A380neo project.
Summary
We thereby see the time ripe for looking into the A380neo again. When we last covered the subject (Updating the A380: the prospect of a neo version and what’s involved, Feb. 3, 2014) we concluded:
• The present configurations for the A380 of 525 seats fills the A380 to a much lower density than is the norm today.
• A cabin configuration of 555 seats would be a realistic three-class configuration with the economy section on the lower deck still in a spacious 10 abreast with seat width at 19 in.
• The efficiency of the A380 filled to that low density was on par with the best per seat benchmarks in the industry, the Boeing 777-300ER with the economy section in a tight 10- abreast, 17- inch configuration.
• The best in market benchmark would move considerably when the Boeing 777-9X enters service 2020. The per fuel seat cost would then we almost 20% lower than today’s A380.
Today our article shows:
• A re-engined A380neo, with other improvements typical in such an endeavor, reclaims the per-seat advantage for the A380.
When re-running the data in our proprietary model, we have more and better data around the likely engine variant, the Rolls Royce Advance, which was announced by Rolls Royce in March. It will be available for an A380neo rolling off the production line 2020. We have also put in more work into our standardized cabins, adjusting the relationship between premium and economy seating to a ratio closer to the one airlines use today. Airbus has also been active on the A380 cabin side. It has had several studies how to better utilize the cabin space in the A380. The results are now presented to the market.
In a recent A380 update, Airbus showed an 11-abreast main economy cabin with 18 in seats, now without raising the cabin floor to fit the seats. By adjusting how the seats interfaces the cabin’s sloping walls, Airbus avoids changing the floor height in part of the cabin.
We will now use this latest data to check where an A380neo would stand in terms of efficiency against the Boeing 777-9X, its most difficult competitor when it comes to the cost of transporting passenger from A to B. In later articles we will look at a more complete cost picture and also look at the A380’s strong side, the revenue and yield when one can fill the aircraft. Read more
Air Berlin 787 cancellation potentially gives Boeing big advantage in Delta order competition
The announcement last week that AirBerlin canceled orders for 15 Boeing 787s gives Boeing an unexpected, big advantage in the contest for a big wide-body order from Delta Air Lines–depending on when Delta wants the airplanes.
The competition apparently has been narrowed to the Airbus A350-900 and the Boeing 787-9, according to Flight Global. Based on this article, the Airbus A330-900 neo has been eliminated, which if true is a blow to the fledgling program in which Airbus had counted on Delta to be a launch customer.
Outside of the OEMs and Delta, it’s not known when Delta wants 50 widebodies. But the A350 and 787 are essentially sold out through the end of the decade, though both OEMs can typically find delivery slots for important campaigns such as this one by over-booking or persuading other customers to move their delivery positions.
Airbus has plenty of slots for the A330neo from 4Q2017, when entry-into-service is planned. But with the apparent elimination of the A330neo from the competition, delivery schedule becomes important–and the AirBerlin cancellation works to Boeing’s advantage.
Odds and Ends: Safran benefits from engine after-market; ExIm could back Airbus; Paine Field future
Engine After-market: Safran, which owns 50% of CFM International with GE Aviation owning the other half, is positioned in the “sweet spot” of the engine after-market, according to a recent report by Bernstein Research.
The report further supports our own analysis posted August 25 and the growing importance of MRO support in winning engine orders.
According to Bernstein, Safran “has the best positioning in the aircraft engine after-market” in the investment bank’s coverage. This position is “driven by two engine families with strong growth ahead and low exposure to older engines that are at risk of early retirement.”
Bernstein notes that more than 95% of Safran’s after-market sales are derived from the CFM56, which powers 75% of the narrow-bodied aircraft, and the GE90, which powers the Boeing 777-200LR/LRF and 777-300ER.
Future programs include the CFM LEAP, GEnx and GP7200. Past programs, in decline, are the first generation CFM56 and the CF6 on earlier wide-bodies.
ExIm and Airbus: In a statement surely to inflame those opposed to renew ExIm Bank authority, the president of the bank said it’s possible it could back funding of the Airbus A320 family built in Mobile (AL).
Paine Field future: It’s a little parochial but The Everett Herald has an article looking at the future of Paine Field, where Boeing’s wide-body airplanes are assembled. The article necessarily looks at the future of the Boeing 747, 767 and 777 Classic production.
Congress is now talking about a nine month extension of ExIm.
Boeing 737 MAX 8 as a long and thin aircraft and how it fares in general versus Airbus A320neo.

Introduction
Over the last weeks we have looked at Boeing’s 757 replacement possibilities on its long and thin network niche, including a ground breaking launch interview for the A321neoLR with Airbus Head of Strategy and
Marketing, Kiran Rao. In the series we have seen that the A321neo has the potential to replace the 757-200 on long and thin international routes. Boeing’s equivalent single aisle entry, 737 MAX 9, has problems to extend its range over 3,600nm. It is too limited in the weight increase necessary to cover the longer range.
Many have asked how the less- restricted Boeing 737 MAX 8 would fare, suitably equipped with the necessary extra tanks. This is the subject of this week’s sequel on the theme long and thin. At the same time we look at Airbus entry in this segment, the A320neo, to see how it stacks up to the 737 MAX 8, both in their normal 1,000 to 2,000nm operation and then also in a long and thin scenario.
Let’s first summarize what we found so far in our four articles around the Boeing 757 and its alternatives:
