Bjorn’s Corner: C Series flight controls
By Bjorn Fehrm
29April 2016, ©. Leeham Co: With the order by Delta Air Lines, the Bombardier C Series has taken the step up to be a viable alternative to Airbus’ and Boeing’s single aisle 130-150 seat aircraft.
In my description of airliners’ flight control and Flight Management Systems (FMS), I have focused on the established mainline single aisle players. Time to change that; C Series has arrived and will stay in the mainline segment.
Why 130 seats as a limit? Because below 130 seats there are a number of additional players (Embraer, Sukhoi, Mitsubishi…) and we can’t describe them all right now.
Now to how Bombardier has implemented the flight controls, autopilot and FMS for the C Series. In fact, we will look at how they have made the C Series cockpit, Figure 1.

I haven’t flown the C Series yet (working on it!) but I have been able to glean quite a bit over time and spent quite some time in the cockpit with the Bombardier test pilots at the Paris Air Show.
So here is a shot at describing the C Series control philosophies and capabilities and how they mimic/differ from Airbus and Boeing.
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.
PW’s Geared Turbo Fan was catalyst for MRJ90 order
March 8, 2016, © Leeham Co.: Pratt & Whitney’s Geared Turbo Fan technology was what prompted a used airplane lessor to place its first new airplane order,

selecting the Mitsubishi MRJ90 in the process.
Jep Thornton is a partner with the small lessor Aerolease, a 20-year old company that has up to now concentrated on acquiring McDonnell Douglas DC-8s, Airbus A300s and Boeing 757s for conversion to cargo aircraft. Aerolease has about 40 aircraft under management and ownership.
Thornton and Mitsubishi announced at the Singapore Air Show last month a Letter of Intent to order for 10 MRJ90s and options for 10 more. Deliveries begin in three years.
ISTAT Day 1: Engine updates for CFM, GE, RR and PW
Feb. 29, 2016, (c) Leeham Co.: The LEAP engine, for the Boeing 737 MAX, Airbus 
A320neo and COMAC C919 is the fastest-selling engine in history, says Jean-Paul Ebanga, the president of CFM International. More than 10,000 have been sold.
- We’re at the 2016 ISTAT AGM in Phoenix and will be reporting today and tomorrow on presentations and news from the sidelines.
“It’s on-time and on-spec,” Ebanga said. It’s either been on the date set four years ago or ahead of schedule. The engines delivered to Airbus for the A320neo are on spec, he said. It’s been certified for the neo and will be certified soon for the MAX, with 90% of the information submitted.
Welcome news for Bombardier, Mitsubishi

Introduction
Feb. 22, 2016, © Leeham Co.: The large order (Letter of Intent) last week by Air Canada for 45 firm and 30 option CS300s was welcome news for Bombardier.
And the LOI from the US lessor, Aerolease, for 10+10 MRJ90s was welcome news for Mitsubishi.
We take a look at both announcements and what this means for the two programs.
Summary
- The Air Canada order breaks the long drought in C Series orders, but it’s not enough for smooth sailing (to mix metaphors) for the aerospace company.
- Continuing the mixed metaphor, Bombardier still has a long hill to climb.
- MRJ order, by little known lessor, helps diversify customer base.
Bjorn’s Corner: Communicate or not?
By Bjorn Fehrm
19 February 2016, ©. Leeham Co: Mitsubishi Aircraft Corporation (MAC) announced on Christmas Day that they delayed the entry into service of the MRJ90 regional airliner by over a year. At the same time, they also announced that they had to reinforce the aircraft’s wing and fuselage.
The market’s reaction to the news was with disappointment. A further delay to a new aircraft from a new player in the market was not good news, but it was not that surprising. Bringing new aircraft to market on time is tough for the established players. Other new entrants, COMAC/AVIC and Irkut, are also running late with their programs, and Sukhoi was late with its SSJ100.
What worried many more was that the aircraft needed reinforcements, directly after its first flights. After only three flights, the aircraft was grounded and was scheduled for changes to its airframe. That was really bad news. “It’s going to be heavier.” How could MAC miss to gravely was the common reaction.
Having worked in a 50% Japanese company for many years, I wondered what was behind this all. Was the aircraft really in dire straits or did we witeness a cultural mismatch I’ve seen many times?
Bjorn’s Corner: Exciting 2016
By Bjorn Fehrm
29 January 2016, ©. Leeham Co: In the corner of two weeks ago we did a retrospective of 2015. Time for looking ahead. The year of 2016 will be quite interesting. We had entry into service of the first re-engine single aisle aircraft this week, the Airbus A320neo, the same week as we expect first flight from its main competitor, Boeing’s 737 MAX 8. We will also see first flight of the Embraer E190E2 and A350-1000 before the year is over.
The Mitsubishi MRJ shall go test flying in earnest and Bombardier’s CSeries 100 and 300 shall enter service. On top of that, the COMAC 919 will probably start ground roll tests this year and we should see roll out of Irkut’s MC-21. I would say 2016 is a busy year for civil aviation.
In the 2015 corner we talked a lot about engine technology as a key driver to further efficiency of air transportation. Now will dissect the airframe technology that all these new projects will bring us. Read more
Pontifications: Shifting focus to Embraer
By Scott Hamilton
Jan. 25, 2016, © Leeham Co. Embraer announced last week it had cut metal on its first E195 E2, more than a month before the roll-out of the first E190 E2, scheduled for Feb. 25, at is Sao Jose, Brazil, plant.
The aggressive manufacturer of small(er) passenger jets is moving forward full speed toward its next generation of aircraft even as Airbus, Mitsubishi, COMAC and Irkut encounter one delay after another.
Bjorn’s Corner: What did we learn in 2015?
By Bjorn Fehrm
08 January 2016, ©. Leeham Co: It’s the first Corner for the year and a look at 2015 as a year of technology advancements is due. 2015 will be remembered as the year when three clean sheet airliners passed important milestones. This will not happen for many years to come, so it will be worth to look at what they brought to world of aviation.
I’m thinking of Bombardier’s (BBD) CSeries getting certification for its first variant; the Mitsubishi MRJ doing its first flight’ and COMAC’s C919 being rolled out. Going forward, we will only have derivatives progressing through such milestones for years except for the roll-out of United Aircraft’s MS-21 single aisle airliner in 2016.
The Airbus A320neo was certified in 2015 and Boeing’s 737 MAX rolled out, but these are derivatives of in-service aircraft.
Embraer’s E-Jet E2 will roll out in February but this is a further development of today’s E-jet and Airbus A350-1000 is a variant of the in-service A350-900.
It will be a long time before we see so much new in a year, so it can be instructive to look at to what extent did these new aircraft bring the state of the art of airliners forward.
