Farnborough Air Show preview: expectations and possible surprises
Subscription Required
Introduction
July 4, 2016, © Leeham Co: The Farnborough Air Show begins next Monday and predictably, focus will be on orders.
With new airplanes from Airbus and Boeing past their development stages, conventional wisdom says there won’t be much new in this arena.
Don’t be so sure.
Bombardier is now on an upward trajectory, but don’t look for a big splash at #FIA16 (for those looking for this year’s Twitter handle). Embraer will have its E190-E2 at the show.
It’s Boeing’s 100th Anniversary and the company is rolling out the history for the show.
Summary
- No new products from Airbus.
- Boeing may have a surprise.
- Low number of orders anticipated.

Introduction
June 16, 2016, © Leeham Co.: A middle of the market airplane will come before a replacement for the Airbus A320 and Boeing 737, predicts Alan Epstein, vice
Alan Epstein, VP technology and environment, Pratt & Whitney.
president of technology and the environment for Pratt & Whitney.
“The challenge to the business of the narrow-bodies is the A320s and the 737s are so learned-out that Boeing and Airbus are so efficient at building those airplanes, that their inherent cost is so low, it’s extremely difficult to move into that market,” Epstein said. “Because the learning curve, you need incredibly deep pockets and you’re going to be negative for a long time.
“I think that also applies to Airbus and Boeing,” Epstein said, referring to the prospect of a new single-aisle aircraft.
Summary
- New single aisle airplane would be a “white elephant” for 10 years.
- Engines need to be at least 10% more efficient than today’s GTF and LEAP for a new single-aisle aircraft.
- Middle-Market airplane likely to come first.
Airbus aircraft programs in review
By Bjorn Fehrm in Hamburg
Introduction
May 31, 2016, ©. Leeham Co: Airbus went through a complete review of all their aircraft programs as part of their yearly briefing for media in Hamburg today. A lot was said regarding the status for the different programs by Airbus CEO Farbice Bregier, its COO customers John Leahy and Executive VP Strategy and Marketing Kiran Rao.

The briefing was given against a backdrop of weak orders and deliveries for the first five months of the year. Both Bregier and Leahy said, “This is to be expected, it’s not sustainable that we have Book-to-Bill ratios (orders vs. deliveries) of over 1.5 or even close to two for many consecutive years. We have a backlog of 6,700 aircraft that customers expect us to deliver and they have little appetite to order new aircraft when they can earliest get them by 2021 at the earliest.
“We are now in a period of focus on deliveries and we can expect and be happy with a book to bill ratio of around one for the coming years. The extraordinary backlog also justifies our decision to increase production to 60 units per month for our A320 single aisle program.”
Here follows what was said for each of the programs.
How good is a MAX 7X and why would it replace the original? Part 4

Introduction
May 23, 2016, ©. Leeham Co:In Part 1 to Part 3 of this article series,we looked into the reasons behind that Boeing is considering changing the 737-7 MAX into a slightly larger 737-7X.

When an aircraft gets larger, its operating costs increase, everything else being equal. At the same time, it can take more passengers. This will increase the aircraft’s revenue generating capability, assuming the network can generate the traffic level needed.
To understand the difference in revenue capability for the 7 and 7X we will now develop their Direct Operating Cost (DOC) and compare these with the revenue generation capability of the aircraft. This gives the margin capability and one can establish where the cross over point would be between 737-7 and 7X with respect to margin for the airline.
Summary
- We develop the Direct Operating Costs (DOC) for the 737-7 and -7X.
- We also develop the revenue streams of the aircraft over typical missions.
- When compared, the margin of the aircraft will result and it will be possible to define the extra passenger count needed for the 7X to deliver the same margin as the presently defined 7 MAX.
- We then can establish the revenue upside potential for a 737-7X over the 7.

Introduction
May 16, 2016, ©. Leeham Co: In Part 1 and Part 2 of the article series we have described the rational for Boeing to change the definition of the 737-7 MAX into something that has the working name of 737-7X. This is a 737-7 variant that is based on a shortened 737-8.
Figure 1. Boeing’s 737 MAX 7. Source: Boeing
In the previous articles we defined a probable size for such a cut down 737-8. The size is determined by economical criteria where the second most dominant cost in an airlines operation, the crewing cost, is the sizing criteria. These costs have a step increase if the aircraft’s seating go beyond 150 seats.
We sized the 737-7X cabin size (and therefore fuselage length) to avoid such cost increases. In this article, we will compare the resulting main data for a 7X to the original 7 and compare their fuel efficiencies.
Summary
- A 737-7X will be a larger and heavier aircraft than the original MAX 7.
- As such it will consume more fuel per mission; its aircraft fuel mile costs will be higher.
- The key comparison for an airline is the fuel consumption per seat mile for its missions. It would be vital that this is lower for a 7X than the presently defined 7.
- We check if this is the case with our proprietary performance model.

Introduction
May 16, 2016, ©. Leeham Co:In Part 1 we described the driving forces behind Boeing’s investigations into changing the definition of the 737 MAX 7.
There are good reasons to make the -7 model larger. The passenger market is moving the average size of the cabins upwards by about 2-3 seats per year. Boeing therefore made the middle model, the -800 and later the MAX 8 larger than the 737-400. It went from 146 seats in two classes to 162 seats.
Figure 1. Boeing’s 737 MAX 7. Source: Boeing
But the -700 and therefore the MAX 7 stayed the same size as the predecessor, the -300 at 126 seats. As described in our last article, this is not an ideal size. You don’t amortize the cost of the aircraft’s crew over an optimal number of passengers at normal loadfactors and you have a smaller number of very specific 737-7 in your fleet. We now discuss what would be a more competitive definition for a 737 MAX 7.
Summary
- The 737-700 and MAX 7, as presently defined, is sized at 126 seats two class.
- A more competitive sizing would be closer to 150 seats in order to maximize the utilization of the regulatory mandated aircraft crew resources.
- The exact sizing will depend on how many seats the dominant customer, Southwest Airlines, wants to have in its one class economy seating, which uses a generous seat pitch of 31-32 inches.
Airbus Group 1Q 2016 results: Slow start to the year, guidance maintained.
By Bjorn Fehrm
28 April 2016, ©. Leeham Co: Airbus Group has had a slow start to 2016. Deliveries of A320neo, A350 and A400M are slowed by problems with engine and cabin suppliers. Only 127 aircraft were delivered out of a total guidance of 670 deliveries for 2016, a mere 18%. Group 1Q 2016 (1Q 2015) revenue were €12.2b (€12.1b) with EBIT of €501m (€651m), down 23% year on year.
The group expects to recover the shortfall in deliveries during the year and to reach guidance levels for revenue and EBIT, except for the troublesome A400M. This time it’s a engine gearbox item which is the culprit. Airbus CFO, Harald Wilhelm, gave a clear warning during the quarterly conference call: the A400M program “risks a significant charge” during the year.
The financial results for the divisions for the quarter were:
- The commercial aircraft division delivered 125 (134) aircraft with revenues €8,668m (€8,565m) and EBIT €407m (€569m).
- Airbus Helicopters delivered 56 (62) helicopters with revenues €1,158m (€1,285m) and EBIT €33m (€52m).
- Airbus Defence and Space revenues were €2,534m (€2,603m) with EBIT €109m (€90m).
Details of the Airbus Group 1Q 2016 results are below.
Virgin America does have some attractive attributes

the surface.
When news emerged last week that VA was shopping itself after interest was expressed, many thought, quite naturally, why?
Dan Reed neatly summarizes this argument in his column at Forbes.
Virgin America has few tangible assets. It leases all but about seven of its 10 Airbus A319s and 50 A320s. It’s not dominant in any city or route it serves. The leases are probably, on a relative basis, rather costly.
It has few slots at the few slot-controlled airports it serves (Chicago O’Hare, New York La Guardia and JFK airports and Washington Reagan National Airport), and only a few gates at any given airport—hardly enough to really boost presence of either Alaska or JetBlue.
Why should either airline want Virgin America?
Here’s why.

Introduction
March. 14, 2016, ©. Leeham Co: In three articles we have been looking at the new Russian single aisle aircraft, Irkut MC-21, from United Aircraft and the new Russian engine that is being developed for the aircraft, the PD-14.
The PD-14, which is offered as an alternative to the base engine for the aircraft, the Pratt & Whtiney PW1400G, was analysed in our Part 3 article. We now mount the engine on the MC-21 and explore the difference in performance compared to the base engine.
Summary:
- The PD-14, which is a new engine designed by the Aviadvigatel company, is a clear step forward for the Russian turbofan industry.
- In our analysis in Part 3, we could see that it has a classical direct drive construction with a good level of technology in several parts.
- Weight and installation dimension are similar to the competition but efficiency is a bit behind.
- We now explore the performance of the MC-21 with the Russian engine.

March 3, 2016, © Leeham Co.: Airbus may well have avoided the supplier-driven delivery delays on its A350s had the company brought some key work in-house and become more vertically integrated, says its chief operating officer-customers.
Airbus has been bedeviled by delays in business class seat and galley deliveries from supplier Zodiac, resulting in delayed deliveries of the A350-900 to several airlines.
John Leahy, in an interview with LNC at the International Society for Aircraft Transport Trading (ISTAT) conference Feb. 29-March 1 in Phoenix (AZ), said Airbus shouldn’t be at the mercy of suppliers of interiors. His wide-ranging interview also touched on several other topics.
