Introduction
November 16, 2017, © Leeham Co.: Yesterday we outlined the qualitative reasons why the Boeing 787-10 was selected for Emirates’ medium-range routes. Now we put figures behind the words.
We will quantify the weight and drag consequences of the tighter packaging of the 787 and discuss what it’s smaller wing means in field performance from a hot Dubai International Airport.
We use our airline performance model to give us the data, flying the aircraft over typical routes.
Summary:
- The A350-900 was designed for flights up to 15 to 20 hours.
- To make these bearable, Airbus decided to offer 18-inch seat width in the nine abreast economy cabin.
- Boeing went another route. It offered a slightly narrower fuselage and let the airlines decide between eight or nine abreast economy.
- Only Japanse ANA and JAL chose the base layout with eight abreast economy (and ANA has since switched to nine abreast economy for new deliveries).
- The result is an aircraft with lower empty weight and fuel burn (everything else being equal).
- For the 787-10, Boeing combined the tighter packaged fuselage with a wing optimised for flights up to 12 hours.
- The 787-10 consequently beats the A350-900 on efficiency for shorter routes.
Why did Emirates choose Boeing’s 787-10?
By Bjorn Fehrm
November 15, 2017, © Leeham Co.: Emirates Airlines (Emirates) has finally decided which aircraft shall complement their long-range Boeing 777 and Airbus A380. The decision coming at this year’s Dubai Air Show was more surprising than the choice, Boeing’s 787-10.
We have already written about the Emirates selection. Now we go through in more detail, why the choice should surprise no-one.

Airbus’ A330 or Boeing’s 787 for LCC long haul?
By Bjorn Fehrm

Introduction
November 09, 2017, © Leeham Co.: International Airlines Group’s (IAG) CEO, Willy Walsh, said in an Investor presentation last week “LEVEL (the group’s Long Haul LCC) is as well off with the Airbus A330-200 as with a Boeing 787.” He said the lower capital costs of the A330 compensates for the Dreamliner’s lower fuel burn.
As a proof, Walsh said IAG had run flight plans with their LEVEL A330 flying the same mission as a Norwegian 787 and configured as the Norwegian aircraft. The difference in fuel burn Barcelona-Los Angeles would be 6t. But this is easily compensated by the difference in capital costs.
Going forward, LEVEL has the possibility to switch to the 787, said Walsh. Our reaction is; why not include the A330neo in this discussion?
We decided to verify Walsh statements and also check why an A330neo wouldn’t be more appropriate than a 787.
Summary:
- The statement by Walsh about the difference in fuel burn between the A330 and the Dreamliner is correct.
- However, fuel cost is no longer the dominant cost in airline operations.
- We compare the total Cash Operating Costs (COCs) of the aircraft, then we view whether the COC difference between the types can be compensated with capital cost differences.
Pontifications: Small Mississippi airport plays key role in state’s aerospace industry
By Scott Hamilton
Nov. 6, 2017, © Leeham Co.: One of my stops during my October visit along the I-10 corridor from Mobile (AL) to New Orleans, through Mississippi, visiting aerospace interests was the Stennis International Airport.
The airport is in Hancock County, an hour’s drive east of New Orleans.
This is on the eastern edge of the Stennis Space Center I wrote about last week and it benefits from being in the Space Center’s shadow. The Space Center is exempt from noise regulations. So is the airport, which enables this one-runway field to be a way point for noisy military jets and trainers and a training location for helicopter-based special forces. These are all noisy aircraft that locals view as routine, says Kevin Carlisle, director of the airport.
Emirates likely to order new A380s at Dubai Air Show
By Bjorn Fehrm
November 03, 2017, © Leeham Co, Hamburg.: Emirates Airline (Emirates) Chairman and Chief Executive Sheikh Al-Maktoum said at today’s delivery ceremony of the airlines 100th A380, “We hope we will be able to order new A380s next week at Dubai Air Show. The details are being worked out.”
His statement came at a press conference with Airbus CEO, Tom Enders, in Hamburg today, at the delivery of the new A380. The delivered aircraft carries a special tribute to the founder of the Arab Emirates, Sheik Zayed (Figure 1).

Why is Airbus A330-800 not selling?
By Bjorn Fehrm
Introduction
November 02, 2017, © Leeham Co.: Airbus A330neo flew its first test mission two weeks ago. The test aircraft was the bigger A330-900, the neo version of the A330-300. For the present A330, the sales and delivery of A330-300 (the 290-seater) and the A330-200 (the 246-seater) is almost even, 720 versus 650 (including 70 MRTT and Freighters for the -200). But sales of the -300 in recent years far outpaced the -200, for which sales virtually dried up.
For the A330neo version, the A330-800 is not selling at all. Six aircraft are on order for Hawaiian Airlines while 211 are ordered for the A330-900. Why?

We decided to use our performance model to understand why the smaller, longer range A330neo has fallen from grace.
Summary:
- The A330-800 flies longer and with lower fuel burn than the A330-900.
- But the differences are not large. And fuel costs are no longer a dominating cost in the overall cost picture.
- For other costs, the types are too similar. The A330-800 doesn’t have any scale advantages over the A330-900; only range, and the A330-900 is flying longer and longer.
Suppliers conference in Mobile focuses on US aerospace sector in Southeast
Click on image for an enlarged, crisp view.
Oct. 31, 2017: A new event, the Southeast Aerospace and Defence Conference (SADC) scheduled for June 25-27 in Mobile (AL), will examine the commercial, defense, space and corporate aerospace sectors in the US Southeast.
The conference is organized by Airfinance Journal and Leeham Co., the first joint venture between the two companies.
The US Southeast is a growing aerospace center. Defense and space clusters have decades-long histories in the Southeast. Corporate and commercial clusters are more recent developments, albeit in some cases now well within a second decade.
Airbus’ A320 family Final Assembly Line in Mobile opened in September 2015. The FAL is producing 3.5 A320s per month and will reach its initial target of 4/mo by year end, slightly ahead of schedule. There is land capacity to expand to 8/mo.
Earlier this month, Airbus and Bombardier announced that their new venture will establish an FAL in Mobile.
Pontifications: Going to space through Mississippi
By Scott Hamilton
Oct. 30, 2017, © Leeham Co., Hancock County (MS): The US Space Shuttle program ended in 2011 and NASA is sending US astronauts to the International Space Station using Russian-made rockets.
But officials want to end reliance on those launch vehicles and are working with US companies to supply the boosters and prepare for a mission to Mars.
Last week, I wrote about Boeing’s efforts to develop the Space Launch System (SLS). I spent the week of Oct. 9 going from Mobile (AL) through the I-10 corridor in Mississippi and ending in New Orleans, gaining a high level understanding of the aerospace footprint in the US Southeast.
The Mississippi portion was arranged by the Mississippi Development Authority. I’ll provide additional reporting in the coming weeks. This week, I focus on NASA’s John C. Stennis Space Center in Hancock County (MS), an hour’s drive east of New Orleans.

Introduction
Oct. 16, 2017, © Leeham Co.: President Donald Trump announced Friday he will decertify the Iran nuclear deal, throwing into doubt a host of related commercial deals, including huge aircraft orders.

Trump hasn’t gone so far as to withdraw from the pact, but he still threatens to do so unless Congress makes changes he wants.
Here in the US, focus is, of course, on the commitment by Iran for Boeing aircraft—none of which are firm contracts, but “commitments” to order.
Of less focus here, if any, is on the outstanding orders placed by Iran for Airbus and ATR aircraft, which are subject to US licensing.
Summary
- 30 Boeing 777s, including 15 Classics are at stake.
- 50 Boeing 737 MAXes to Iran Air and 30 to Iran Asesman are also at stake.
- ATR has 11 aircraft scheduled for delivery in 2018.
- Airbus sold 114 A320s/321s, A330s and A350s to Iran Air. A few white tails already have been delivered.
