Bjorn’s Corner: Embraer’s Fly-by-wire approach
By Bjorn Fehrm
08 April 2016, ©. Leeham Co: Two weeks ago we discussed the advantages of a Fly-By-Wire (FBW) system which uses feedback based flight laws. We discussed the fact that aircraft OEMs can get the desired FBW handling characteristics with smaller horizontal tail surfaces. I put forward the Embraer E-Jets as an example where the change of FBW principle allowed a 26% reduction in the horizontal tail size for the E2 generation.
At the time there were some debate on how this was achieved and what the root cause of the improvement was. Embraer followed the discussion and told me when I contacted them that my information was correct. In the interest of our readers, Embraer agreed, however, to have their FBW team to give a more complete picture of the advantages of a feedback based FBW.
Here is the team’s response. Read more
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.
Nordic Aviation Capital completes second major acquistion
March 15, 2016: Nordic Aviation Capital yesterday announced it acquired regional aircraft lessor Jetscape Aviation Group. This is the second major acquisition since 
December. Then, NAC agreed to acquire 25 ATR turboprop aircraft from Air Lease Corp., which decided to focus entirely on jets, most of which are mainline aircraft. All but a handful of the ATRs were already leased, with the remaining still in production.
Nordic had nearly 250 aircraft from the ATR and Bombardier Dash and Q families, plus a small number of Bombardier CRJs, Airbus A320s and Boeing 737s. The Jetscape acquisition brings Embraer EJets to the Nordic portfolio.
“The deal will see Nordic Aviation Capital expand into the regional jet arena, bringing 28 owned Embraer E-Jets, commitments for 11 E-Jets and a further 18 of the type under management into its sizeable regional aircraft portfolio,” the company said in a press release.
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.
EJet-E2 ranged upped by 450nm
Feb. 24, 2016, © Leeham Co., Sao Jose dos Campos: The new Embraer EJet E2 will have 450nm more range than the previously advertised 1,920nm, the company announced today.
Luis Carlos Affonso, senior vice president of Embraer Commercial Aircraft, announced the change during media briefings in advance of the E190-E2 rollout tomorrow at the EMB plant here.
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
Analysis: Sukhoi’s regional jet Superjet 100

Introduction
18 January 2016, © Leeham Co: Russian aircraft have never succeeded in penetrating the Western market. But then they never really tried, until now. They were designed for the Soviet Union captive market, including the partner states that historically participated in or were friendly to the communistic system. One comes to think of China, Egypt, Libya, Cuba and Nicaragua.
The Sukhoi Civil Aircraft Company (SCAC) Superjet 100 (SSJ100) is the first Russian aircraft specifically designed from the outset to compete on a world market.
We analyse its basic design and performance in comparison to the market leader in 100 seat regional flying, Embraer’s E190.
Summary:
- The SSJ100 is a half a generation younger design than the Embraer E190. It has modern aerodynamics, IMA-based modular avionics and an advanced Fly-By-Wire system.
- The feedback-based Fly-By-Wire enables a tight aircraft design with low wetted areas.
- The SSJ100 engines, SaM146, can best be described as a shrinked and cleaned up CFM56. They have the efficiency level of the E190’s CF34-10E.
- The aerodynamics and engines combine to give the SSJ100 a single digit edge in fuel burn over the E190.
The turbo-prop conundrum: small market, high costs

Introduction
ATR and Bombardier are incumbents. China has a home-market offering.
Indonesia and India want to create a product.
It’s the 60-seat and up turbo-prop market.
It’s too many companies chasing too-small a market.
Summary
- The 20-year demand for 60-99 seat turbo-props is small.
- Developing a new, clean-sheet design is costly.
- There is a solid demand for an inexpensive 19-34 seat turbo-prop—but nobody is interested.
