Pontifications: Airbus USA321 a milestone for US aerospace
By Scott Hamilton
March 28, 2016, © Leeham Co.: The first US-built A320ceo family member took to the skies for its first flight last week. The A321ceo, destined for JetBlue, is the first assembled at the new Airbus A320 plant in Mobile (AL).
This is a milestone for Airbus, obviously. The Mobile plant was first proposed as the assembly site for the KC-330 MRTT (Multi-Role Tanker Transport) proposed for the US Air Force to replace the aging Boeing KC-135s. Northrop Grumman, which paired with Airbus parent EADS (as it was then known) to offer the KC-330, won the contract. The celebration was short-lived. The Government Accountability Office overturned the award. Northrop bowed out of the next round of competition, which Boeing won.
Airbus subsequently decided to create an A320 assembly site at the same Mobile location planned for the KC-330. (I visited the site for grand opening last September.)
This is the fourth A320 assembly site, after Toulouse, Hamburg and Tianjin. Airbus hopes the Mobile site will help spur sales in the US, where it still trails Boeing in market share.
Milestone for US Aerospace
While this plant is a milestone for Airbus, it’s a milestone on a much more macro level, too. This is the first commercial airplane assembly site by a second airplane manufacturer since Boeing closed the McDonnell Douglas MD-11 and MD-95 (aka Boeing 717) assembly lines in Long Beach (CA) in 2000 and 2006, respectively. The last legacy MDC assembly site, for the military C-17, closed early this year.
Bjorn’s Corner: Flight control, Part 3
By Bjorn Fehrm
25 March 2016, ©. Leeham Co: Last week we covered the natural stability of commercial aircraft and the most important movements the aircraft would go into if we had no pilot intervention.
Now we will cover how Fly-By-Wire (FBW) systems make enhanced flight control laws practical to implement. We will cover the principal build up of a FBW system with enhanced control laws and two of the most common approaches used in the market for such control laws: the Airbus and the Boeing implementations.
The discussion will focus on the essential and forgo many deeper discussions over redundancy and safety. Otherwise the subject expands into a book rather than an easy to read article and that is not what we want.
PW Canada continues next-gen turboprop development despite airplane demand uncertainty

March 24, 2016, © Leeham Co.: Pratt & Whitney Canada (PWC) continues development of the next generation turboprop engine, even as low oil prices reduce the attractiveness of turboprop airplanes.
Few believe oil prices won’t creep back up over time, once again making prop-jets attractive once again. The ancillary question is what’s next for this type airplane? An entirely new, clean-sheet design? A 90-100 seat turboprop airplane? Or retrofitting this next-gen engine on today’s turboprop airliners?
Summary
- PWC’s new engine could be fitted to a new airplane design or retrofitted to today’s Bombardier Q400 and ATR series airplanes.
- The 20-year market is small.
- The 20-year market for a 90-seat turboprop is smaller still.
- Embraer is evaluating whether to reenter the turboprop market, 15 years after the last mass-produced Brasilia rolled off the assembly line.
- GE is developing a turboprop engine and at least three countries have interest in this sector.
Airbus reveal “Airspace” interior for A330neo ahead of Interiors Show

March 24, 2016, © Leeham Co.: Airbus launched its Airspace brand for a new cabin design for the A330neo, two weeks ahead of the big, international Aircraft Interiors Expo April 5-7 in Hamburg. The news made a big splash in social media and ups the game in the passenger experience competition with rival Boeing.
A series of Airbus photos may be found here.
The interior redesign for the A330 is overdue. While the current offering is pleasant enough, and it’s functional, Boeing’s interior designed for the 787 and subsequently adapted to the 737 and 747-8, was stunning when first unveiled more than a decade ago.
Airbus exploring higher capacity A350
By Bjorn Fehrm
23 March 2016, ©. Leeham Co: Airbus is showing a select group of airlines a stretched version of the A350-1000. The idea is to get enough feedback from potential customers so that a decision to go ahead or not can be made during the summer. Airbus COO customers, John Leahy, told LNC at the ISTAT conference earlier this month that an announcement could be made at the Farnborough Air Show in July. Other sources say it might take longer.
We have covered the possibility to extend the A350-1000 to a longer 400 seater version in several articles over the years. The key question for Airbus is how large is the market for a dual aisle twin with 400 seats and has Boeing already covered a large part of that market with its 777-9?
What has changed now it that the A350-1000 is taking form on the Airbus Toulouse Final Assembly Lone (FAL) and Airbus can now see that the A350-1000 will hit its performance and weight numbers. Airbus also has a lot of learning from the A350-900 which makes it confident that an A350-1000 stretch can be made with rather small changes.
Pontifications: Why the 787-8 is no longer favored by Boeing
By Scott Hamilton
March 21, 2016, © Leeham Co: My Pontifications for the last two weeks examined how the Airbus and Boeing messaging continues to do battle for the product line ups. Boeing continues to denigrate the Airbus widebody line and Airbus fighting back, using Boeing’s own tactics alleging a product gap.
Boeing claims then A330neo is “dead on arrival” and the Airbus widebody strategy is “a mess.” Neither claim holds up under scrutiny. Certainly there is some weakness in the Airbus line: the A330-200 sales slowed to a trickle and the A330neo, especially the -800, has yet to truly advance. The A380 struggles and the A350-1000 is slow—but after the initial, unique splurge of the 777X, sales of this airplane have been anemic, too.
Airbus points out the sales of the 787-8 have dried up. So have sales of the 777-300ER, in sharp contrast to the unexpectedly strong sales for the A330ceo—enough so that Airbus is taking the production rate back up, to 7/mo, from the previously announced reduction to 6/mo.
Here’s why the 787-8 has become a dying sub-type.
Aircraft programme cost
By Bjorn Fehrm
Subscription required.
Introduction
March. 21, 2016, ©. Leeham Co: There is quite a lot of talk about what a new aircraft program like Boeing’s Middle of the Market (MOM) would cost the airframe OEM to develop. Typical quotes are “it would cost them at least $10bn.” When saying this, the person implies this is the program’s load on the company’s liquidity for that aircraft program.
This is not correct and we will now go through why. It might be true that the development of the aircraft cost $10bn. But the trouble is, this is not the only cost that will hit the OEM for this aircraft program.
Cost that one normally does not think about when talking about new aircraft programs can double the cash burden on the OEM. Here’s why.
Summary:
- What normally is labeled development cost is only to a part development.
- About half of the cost is used to develop and manufacture the aircraft’s production tooling.
- There is one major cost block that has been forgotten in a development cost discussion: initial production costs.
- The initial production costs not covered by customer payments can double the cash burden for a company.
Bjorn’s Corner: Flight control, Part 2
By Bjorn Fehrm
18 March 2016, ©. Leeham Co: Last week we covered the early days of flight control when the pilot controlled the aircraft’s movable surfaces (called movables; e.g. stabilator, rudder, ailerons, spoilers…) without the involvement of computers.
We will now continue with more advanced control systems, all based on the electrical signalling of the intentions of the pilot to the movables. As the modern Fly-By-Wire (FBW) control systems modify the aircraft’s basic flying behaviour, we need to start with understanding what that behaviour is. Then we can understand how different FBW systems go about modifying these characteristics.
One could think that an aircraft is made to fly nice and stable, should the pilot take a few seconds and admire the view. Nothing could be further from reality. All normally stable aircraft which do not employ flight computers or autopilots to enhance the normal stability would go into a rather nasty dive after a while.
Why this is so and what is done to help the pilot in modern FBW systems is the subject of today’s and next week’s Corner.
Pontifications: Advancing EIS for 777X
Special Edition of Pontifications
Advancing EIS of the 777X
By Scott Hamilton
I’m somewhat bemused by all the fuss over the prospect of Boeing advancing the delivery of the 777X from early 2020 to late 2019. This has been the plan for more than a year. That’s what my sources have been telling me all this time.
It’s been the desire longer that that.
