Development of the GE9X for the Boeing 777X
Jason Brewer, general manager of GE Commercial Engines Marketing, appeared at last week’s Pacific Northwest Aerospace Alliance 2014 conference on the Big Engines panel.
Brewer discussed the development of the GE9X for the Boeing 777X, outlining the new technology going into this big engine for Boeing’s latest 7-Series aircraft.
One slide–which is available to the conference attendees–showed a market forecast of 3,000 aircraft in a context that appeared to suggest GE sees a market of this number of airplanes for the 777X. We clarified this with Brewer after the panel; the forecast is for the 350-400 seat sector. Brewer told us that GE hopes to capture 1,700 of these aircraft.
This is the first time we’ve seen this sub-sector broken out–Airbus and Boeing typically forecast for the larger 300-400 seat sector in their 20 year forecasts. Airbus and Boeing have previously indicated they think the demand for the 400-seat aircraft (i.e., the 777-9X) is between 670-780 respectively.
The sound is pretty soft on this. It will best be heard with headphones.
Updating the A380: the prospect of a neo version and what’s involved
Recent headlines and this column report that Airbus is considering re-engining the popular A330 with GE Aviation GEnx or Rolls-Royce Trent 1000-TEN power plants. A New Engine Option and other changes would improve the A330’s economy by an estimated 10% percent after offsets for increased drag and weight.
But the A330 isn’t the only Airbus airplane being considered for new engines made popular by the A320neo family. Tim Clark, president and chief operating officer of Emirates Airlines, urged Airbus to improve efficiency of the giant A380 with engine technology found in newer generation aircraft.
How feasible is an A380neo? What are the technological issues? Would there be enough of an economic gain? And is there a market for an A380neo?
The A380 of today
The A380 has been hailed as a highly efficient airliner since it went into service 2008, assuming the giant plane can be filled. But only six years later, the first voices have been raised that this will not continue to be the case should the continuous improvements that have been flowing into the airframe not pick up speed.
The launch of the Boeing 777X also brought focus on the state of the A380 come the latter part of this decade when the 777-9X enters flight testing in advance of its planned 2020 entry-into-service. Tim Clark expressed that “it is time that the A380 gets an injection of the new technology which is now becoming available for the A320/737 in the form of GTF/LEAP and GE9X for the 777X. “
Before we look into what can be done short-to–mid-term to inject improved efficiency, let’s establish the baseline as it exists today. The A380 is considered by some the most efficient way of flying passengers between two long haul points if there is enough of demand. The competition today is the Boeing 777-300ER and 747-8i. (Qantas Airways is dropping some A380 flights that have 50% load factors, demonstrating the aircraft is inefficient if the demand is insufficient.)
Let’s assume we want to transport passengers between San Francisco and Hong Kong, one of the longer flights which are made non-stop in both directions. Going West, it takes a Cathay 777-300ER 15 hours and going East, 12 hours, the difference being due to prevailing headwinds going West. For our check, we will use the more demanding of these legs, which then works out as the equivalent of flying 7,200nm. To compare the three different aircraft in a fair way, we need to load them to the same payload, in our case passengers with luggage. We will not consider cargo in this initial analysis. The leg chosen is not one which allows much weight for cargo, but cargo certainly belongs to a complete analysis of an airplane and we will point out where it will affect any conclusions.
When comparing the standard three-class seating numbers between the OEMs, it is clear these are not made to the same standards of comfort. Airbus has admitted that the A380 is too lightly loaded at 525 passengers. The 777-300ER at nine abreast and 365 seats is equipped with a comfortable 18’’ economy class at 32’’ pitch but the business class is modeled with a non-standard 48’’ pitch. The 747-8i at 467 seats is not laid out to any comfort standards comparable to the other two. To ensure an apples-to-apples comparison we have equipped all aircraft with the same three-class cabin with a standard seating consisting of first class at 81’’ pitch, business class at 60’’ pitch and economy class with 32’’ pitch. Seat widths are 37’’, 22’’ and 18’ respectively and the ratios of the different premium seatings vs. economy are kept the same. Here the aircraft are listed with the in-service year and with their respective payload capabilities:
A330neo prospect gains traction
Note: The following was distributed to our e-mail list December 23. Last week, American Airlines (as predicted) swapped the A350-800s for A350-900s.
The possibility of Airbus launching an A330 new engine option appears to be gaining ground.
Our Market Intelligence tells us that Airbus is considering a decision soon, probably next year, with a target entry-into-service date of 2018.
A decision to proceed with an A330neo would come after one to drop the A350-800, according to our information. Airbus has systematically switched -800 customers to the larger, and more profitable A350-900 and A350-1000. There are now just 79 A350-800s in backlog.

We identify 37, or 47%, that probably are already at risk of cancellation in favor of the larger A350-900 or A350-1000. These 37 are highlighted in red and pink. Another 10, those for Yemenia, are probably already iffy, according to Market Intelligence. The total of 47 represents 59% of the backlog. We have no information on the remaining customers’ intentions.
Odds and Ends: AirAsia on A330neo, A380; 777X specificiations; A380 engine PIPs
AirAsia on Airbus: AirAsia Group is one of Airbus’ largest customers, and its CEO Tony Fernandes is increasingly influential in the Asian sector. He’s also into car racing, often betting Virgin Group’s Richard Branson. This short interview details Fernandes’ view on the prospective A330neo–something Fernandes has been pushing for some time–and what he thinks Airbus should do with the A380.
Looking at the 777X: Aviation Week has a detailed look at the Boeing 777X “under the skin.” Fuel burn, engine thrust and general specifications are in the article. Aviation Week also has a series of videos from the Dubai Air Show here. Topics: 777X, Qatar Airways and A380 engines. On the latter, Emirates CEO Tim Clark suggests putting the new GE9X or Rolls-Royce Trent on the A380 to reduce fuel burn by 10%.
Airbus’ A350-800 dilemma
Last week we discussed Airbus’ A350-1000 dilemma. The -1000 will be a fine airplane, but we concluded the company needs to go forward with a larger capacity “A350-1100” to match the size of the Boeing 777-9X, but take the Boeing 787-10 approach and be content with sacrificing range in lieu of designing a new wing and engines.
Airbus’ A350 dilemma doesn’t end there. What’s it to do with the A350-800? One fleet planner told us a year or more ago that the “-800 is an expensive A330-300” with the same operating costs as the larger capacity A350-900.
Airbus has been encouraging customers to move up to the larger A350-900, with Hawaiian Airlines and US Airways the key hold outs. Conventional wisdom says US Airways will swap its order once the merger with American Airlines goes through (which is looking more and more likely, given settlement talks with the Department of Justice). American has a large order for the Boeing 787-9, making the -800 unnecessary in a combined carrier fleet plan.
There are now around 80 -800s in Airbus’ backlog, and even officials at Airbus have been ambiguous about green-lighting production of the -800, which is supposed to enter service in 2016 (after the -900 but before the -1000). We have written several posts in which we concluded the -800 would be re-sequenced to 2018, after the 2017 EIS of the -1000.
We believe there is a very good chance the A350-800 will be dropped in favor of proceeding with an A350-1100.
So what’s Airbus to do in the 250-300 seat space now occupied by the -800 and the aging A330 family?
Odds and Ends: Supply chain demands; Southwest hints?; Retrospective on A320/737 replacements
Supply chain demands: Earlier this week, we talked about the prospect of production wars as Airbus and Boeing ramp up over the next five years, combined with the new entrants and the new offerings from Bombardier and Embraer.
We noted that this will mean opportunity and risk for the supply chain. Ryan Murphy from Salem Partners has a long analysis the starts with the finishing sector but which goes beyond this to discuss the broader implications. It makes for an interesting read.
Southwest: Hints of things to come? Yesterday we wrote about Southwest Airlines and the demise of the Wright Amendment that restricts travel from Dallas Love Field. We suggested several routes that Southwest would launch from Love once the Amendment passes into history.
Here’s a display Southwest erected on its countdown to the end of the Wright Amendment. We think it hints at things to come. Going clockwise: Chicago, New York and Charlotte seem to be where the airplanes are going. Then Los Angeles and Salt Lake City seem to be implied destinations. But the last one? Boise, or some other obscure city?
Or are we reading too much into the placement of these airplanes?

Our thoughts:
Retrospective: We were looking at previous posts for some specific information and in the process re-read one about replacing the Airbus A320 and Boeing 737. The post dates from 2009. In light of subsequent events, it makes for interesting re-reading. We discuss the internal views of Airbus and Boeing about replacement or re-engining their aircraft and the engines from Pratt & Whitney and GE Aviation/CFM. We also touch on Boeing leaning toward not replacing the 777.
Retrospective, Part 2: Airchive has a nice set of historical looks at the development of the Boeing factory at Everett: Part One and Part Two.
Asiana 777 crashes in SFO
An Asiana Airlines Boeing 777 crash-landed at San Francisco Airport Saturday, killing at least two. This is the first fatal crash involving a 777.
Investigators will certainly look at whether fuel line icing may be a factor, which was traced to be the cause of the only other 777 accident, British Airways at London several years ago, also a crash-landing situation. Early news reports seem to reflect a similarity in the flight profile between the two flights. As readers know, we’re traveling and we don’t have access to our files to determine if Asiana uses Rolls-Royce engines, which are those used on BA and which were susceptible to icing.
GE engines on the 777-300ER have more recently come under some scrutiny for issues, and we’d expect investigators to consider whether there is any connection if Asiana uses GE on its 777-200s. This would be a natural course of considering all possible factors.
Other factors that will be looked at: human error, mechanical problems and controlled flight into terrain (CFIT).
Update, 5pm GMT: With the knowledge now that the engines are PW, fuel icing as a cause seems pretty unlikely, but CVR and FDR readouts will indicate engine performance parameters. Although weather doesn’t appear to be a factor, it will be evaluated for the prospect of any clear air windshear or other conditions that could be a contributing cause.
Statements by the airline officials at this point that there wasn’t any pilot error or mechanical issues are entirely premature, given when the statements were made the data recorders hadn’t been recovered much less read.
Closely looking at a photo seems to indicate the aft pressure bulkhead in place, meaning the tail severed aft it it.
