Introduction
August04, 2016, ©. Leeham Co: With the classification of the Irkut MC-21-300 done in terms of its size segment (it’s close to the Boeing 737 MAX 9 in size) and the key data of the aircraft analyzed, it’s now time to look at aircraft efficiency and payload-range performance.

We will do this with two cabin configurations for the aircraft. The first will be the nominal two class seating as proposed by the OEMs. For the second, we use a single class layout with 30-inch seat pitch.
Summary:
- The MC-21 has problems to compete with the re-engined 737 MAX 9 in terms of efficiency when using the standard two class cabins.
- When we switch to a single class high density layout, the fuel efficiency improves. The MC-21-300 exit concept is then more similar to the MAX 9, which affects efficiency in a positive way.

Introduction
August 01, 2016, ©. Leeham Co: After having found the nearest competitor to the Irkut MC-21-300 as the Boeing 737 MAX 9 in our first article, we now go deeper in the comparison of the two aircraft.

In the first article, we found that the aircraft have almost identical cabin dimensions. Now we will look at other areas like airframe dimensions, weights and data which dictate overall performance.
Summary:
- The MC-21 has cabin dimensions which are very close to the 737 MAX 9.
- The nominal two class seating by Irkut is lower than the MAX 9. We have assumed that this will increase during the lifetime of the MC-21.
- We also compare other data between the MC-21-300 and the MAX 9, such as weights, wetted areas and effective wingspans to see if these are similar as well. In the end these dictate the aircraft’s efficiency together with the engines.
Airbus Group 1H2016 results: Trouble in key programs
Updated with analyst reports.
By Bjorn Fehrm
27 July 2016, ©. Leeham Co: Airbus Group presented its first half year results today, posting strong results in the face of delivery troubles with the A320neo and A350; and more charges on the ailing A400M. It has been a troubled start to 2016 with deliveries in key programs (A320, A350, A400M, Super Puma H225) being far behind targets. In total only the space segment is going well in Airbus Group at the moment.
The key commercial aircraft segment is still enjoying a vast backlog (6,700 aircraft) and sales which point to a book to bill of one for the year. But deliveries are not going well. Twenty A320neo “gliders” are just now getting their first engines and the A350 delivery problems are dragging on.
On top of that, the A400M program has hit new problems in the engine area where the propeller gearbox needs a redesign. An interim fix is needed to keep customers flying.
Airbus helicopter side has also hit trouble. The large Super Puma H225 helicopter suffered a fatal off-shore area crash in April and is still grounded as the investigation to what broke in the helicopter is taking time.
The financial results for the Airbus Group for the first half of 2016 (1H 2015) were revenue €28.8b (€28.9b) with net profit €1.8b (€1.5b). These figures includes €1.9b in write offs (A400m €1b, A350 €0.4, Currency €0.5b) and €2.1b in capital gain one offs (Launchers JV valuation €1.1b, Dassault shares €0.9b, Divestitures €0.1b). This means that one time effects kept the result up for 1H 2016 but these will not be there the next quarters should the troubles continue. Airbus Group maintains 2016 guidance for Revenue, EBIT and Free Cash Flow.
Here the details of the Airbus Group divisions results for first half 2016:
Flying the Irkut MC-21 simulator
By Bjorn Fehrm
21July 2016, ©. Leeham Co:Russia’s United Aircraft Irkut division had the good taste to bring a fully functional MC-21 simulator to Farnborough Air Show. I managed to get an hour of take-offs and landings during the show’s early hours on Thursday.
The simulator consists of a fixed cockpit, Figure 1, with a panoramic screen giving a terrain view out of the cockpit windows. The terrain model was of good quality and the feeling of flying a good non-moving simulator was there.

The simulator was especially conceived for exhibitions but it didn’t seem to be less functional because of that. Flight laws should be the same as the full MC-21 simulators but the implementation team is separate from the team which is making the flight crew training simulators. I was accompanied in the Sim by Sergey, one of the software programmers of the simulator. He was interested in my impressions, as it was still relatively early days in the simulator’s design.
Interview with Rob Dewar: CSeries in service reliability

Introduction
21July 2016, ©. Leeham Co: Bombardier”s CSeries project has passed one hurdle after another during its development. The last one was the lack of Marquee customers on top of launch customer SWISS. This has now been solved with large orders from Air Canada and Delta Air Lines.
There is one hurdle remaining: what will be the aircraft’s reliability when it enters into service (EIS)?. We did the EIS interview with CSeries VP and program manager Rob Dewar only two days before the CS100 aircraft would fly its first operational sectors with Swiss last Friday. This autumn, airBaltic will put the larger CS300 into service.

Summary
- The CSeries has been designed for in service reliability from the outset of the project.
- Systems and solutions have been primarily chosen for the in-service maturity on other platforms.
- Any deviation from this philosophy, like for Fly-By-Wire, Geared Turbo Fan or Electrical brakes, requires that the technology earn its place in the project by bringing unique advantages.
The A380 investors day jinx
- July 15, 2016, © Leeham Co., Farnborough Air Show: At an event like this, we pick up all sorts of snippets that don’t fit into any given story. So here’s a compilation of our Odds and Ends to wrap up our dedicated coverage of the 2016 Farnborough Air Show.
A380 and investors meeting: The Airbus A380 has been a sensitive topic for investors. Historically stock prices took a major hit when negative news about the A380 emerged. During an investors day in December 2014, one of the executives slipped that the program could be terminated. The stock took an immediate dive and other executives had to clean up the first one’s comments.
Airbus also holds an investors day during the Paris and Farnborough air shows. The latter’s was scheduled on Wednesday. The night before, the French newspaper La Tribune broke news that the production rate of the A380 will be reduced from 20/yr in 2017 to just 12/yr in 2018. Airbus scrambled to catch up to the story Tuesday night in advance of the Wednesday investors day.
The production breaks even at 20 but not at 12. Yet the stock opened down slightly and remained flat during the rest of the day before closing up slightly.
The jinx may be over, but perhaps Airbus either has to fix the A380 program or cancel its investors days.
Bjorn’s corner: Farnborough week
By Bjorn Fehrm
July 15, 2016, ©. Leeham Co, Farnborough Air Show: We have been at Farnborough Air Show this week, the highlight of the year for an aircraft geek like me. This year there were several interesting aircraft that visited the show for the first time.
Embraer brought over the brand new first prototype of the E-jet 190-E2 and the prototype of their military transporter, the KC-390. Bombardier had their first customer/production CS100 from Swiss to visit the show in addition to their Flight Test Vehicle (FTV) no 5. And Lockheed Martin had the F35B, the vertical landing version, come and hover over the airfield the days that were reasonably rain free in the afternoon.
One thing is clear with the new generation of Single Aisle aircraft: their high bypass engines dominate the visual appearance. Figure 1 shows the 73 inch version of the Pratt & Whitney GTF on the E190-E2 prototype. Huge diameter engine on a not so huge diameter aircraft.

Antonov betting on Western technology
By Bjorn Fehrm
July 14, 2016, ©. Leeham Co, Farnborough Air Show: The company Antonov is world renowned for its rugged transport aircraft. The recent An-124 Ruslan and An-225 Mriya super-heavy transporters are the world’s largest transport aircraft. Both fly daily for the Antonov companies own airline, transporting outsize cargo for companies like Boeing, Airbus, GE, Rolls-Royce and others.

The air freighter company is what keeps Antonov afloat, for it has been hit hard by the fall of the Soviet Union and Ukraine’s decision to split with the Russian Federation and orient itself to the West. Read more
Bombardier’s CS100 media flight demonstrates quiet
July 10, 2016, (c) Leeham Co.: Our coverage of the Farnborough Air Show (#FIA16 on Twitter) begins today, with a media flight on the Bombardier CS100. The day was rainy and somewhat turbulent until the flight got above the clouds. Some videos are jumpy as a result.
There are several videos about the flight and some with interviews following the page break.

The first video is intended to demonstrate the quiet Pratt & Whitney engines during taxi.
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.
