Embraer thinks a business case can be made for turboprop, but nothing soon
Subscription Required
Introduction
March 12, 2018 © Leeham Co.: Embraer isn’t planning any new airplane any time soon, but studies about a turboprop and an electric airplane are underway.
One concept of the Embraer turboprop under study.
The current focus is on introducing the Ejet-E2 into service, however. The E190-E2 goes into service next month. The E195-E2 follows next year and the E175-E2 in 2021.
Studies about the electric plane, with 50 passengers or less, perhaps are more esoteric than pending reality. Airbus and Boeing also are studying this concept.
The prospect of a turboprop may be more rooted in reality, however.
Summary
- Current turboprop designs are aging.
- Bombardier’s exit from the turboprop market is considered likely.
- Tough business case seen working with Bombardier exit.
- The ATR is too small for some airlines.

Introduction
March 5, 2018, © Leeham News: Airbus rolled out the first A350-900ULR the other day. The aircraft will be delivered to Singapore Airlines later this year. Singapore Airlines will use the aircraft to reopen the famous 20-hour flight, Singapore-New York. It will also fly to Los Angeles.
Airbus says the aircraft has a range of 9,700nm, but without saying under what conditions. How many passengers can the aircraft take and in what type of seats are these sitting?

We use our airliner performance model to bring clarity.
Summary:
- The A350-900ULR is touted as a 9,700nm range airliner. This is with restrictions on the number of seats and passengers, far from the nominal 325 seats capacity.
- We use a method we learned from Qantas to evaluate the capacity of A350-900ULR.
- With a Singapore decision to only offer Business and Premium economy seats for the ULR flights, the A350-900 will be space-limited for all flights except the Singapore-New York route.
Embraer ponders new, smaller jet
Subscription Required
Introduction
March 5, 2018, © Leeham Co.: News emerged last week that Embraer is considering a new jet family smaller than its current E2 line.
This would replace the E170, which Embraer decided not to upgrade to the E2. The E170 hasn’t sold well
in recent years, as the E175 became the preferred airplane in Embraer’s sub-90 seat market.
Embraer recognizes it needs a second family of airplanes to complement the E2. It’s been considering reentering the turboprop market, but demand is limited.
Restarting a sub-76-seat jet is not without risk, however.
Summary
- Turboprop market is small over 20 years.
- 60-99 seat market is a bit larger, but with competitors.
- Business cases for each are challenging.
Professionals see two types for Middle of the Market sector
Subscription Required
Introduction
March 1, 2018, © Leeham Co. Three industry professionals raised the question whether the Middle of the Market sector requires one aircraft type or two.
One raised the prospect Boeing might have to undertake concurrent aircraft development, as it did with the 757 and 767.
Richard Aboulafia, a consultant with The Teal Group, Ron Epstein, aerospace analyst for Bank of America Merrill Lynch and Kevin Michaels, president of AeroDynamic Advisory, made their remarks at the annual conference of the Pacific Northwest Aerospace Alliance last month in Lynnwood (WA).
Summary
- Low-cost Embraer engineers may play a role in Boeing’s development of the NMA.
- One consultant sees two distinct NMA aircraft.
- Boeing’s vertical integration of the supply chain may make sense only with two concurrent of consecutive airplane programs.
Aerion’s supersonic engine presented

February 26, 2018, ©. Leeham Co: Aerion Supersonic’s CEO and Executive Chairman, Brian Barents, presented the first pictures of the Aerion AS2 biz jet’s engine at the recent PNAA conference in Seattle.
It’s the first engine adapted for supersonic passenger transport since the Concorde’s Olympus engine was developed in the 1960s.

Based on the released configuration sketch, we put the engine through our GasTurb modelling software. Here’s what we found.
Summary:
- The Aerion AS2 engine combines the CFM56 core with a new high Specific Thrust low-pressure spool.
- Through the AS2’s M1.4 cruise speed limit, complex variable engine inlets and outlets can be avoided.
Hawaiian Airlines’ switch from A330-800 to 787-9

Introduction
February 22, 2018, ©. Leeham Co: Hawaiian Airlines (Hawaiian) were one of the customers for the Airbus A350-800, the smaller, longer-range variant of the A350. When Airbus decided to not produce the A350-800, Hawaiian switched to the A330-800 instead, a smaller and shorter range aircraft.
The further change to the Boeing 787-9 is switching back to an aircraft the class of the original choice, the A350-800.
We examine the change from the A330-800 to the 787-9. What does it buy Hawaiian and why the change?
Summary:
- Hawaiian opted for a smaller sub fleet of very long-range A350-800s when it reviewed its long-range fleet needs in 2007. Future routes could include Europe given the capabilities of these planes.
- When Airbus canceled the A350-800 variant, the order was changed to the smaller and shorter range A330-800.
- Hawaiian has now decided to move back to the type of aircraft it originally decided on. A type which could reliably fly to Europe from Honolulu, the 787-9.
Airbus, Boeing likely to push for 70/mo single aisle airplane production rates: analysis
Subscription Required
Introduction
Feb. 19, 2018, © Leeham Co.: Production rates for the Airbus A320 and Boeing 737 families are already at record levels, and heading higher.
Airbus plans to hit a production rate of 60/mo next year. Boeing is taking the 737 to rate 57. Boeing is studying rates of 63/mo and even 70/mo. Airbus is sure to match.
How will the airframers achieve these rates?
Information gleaned from the sidelines of the Pacific Northwest Aerospace Alliance conference last week give a reasonably good picture of how Boeing will get there.
Visibility was less on Airbus, which is unsurprising given the conference was in Boeing’s back yard in Lynnwood (WA).
Airbus, plagued by “decapitation,” faces tough choices on NMA: consultant

Introduction
Feb. 15, 2018, © Leeham Co.: Airbus’ plans to respond to Boeing’s prospective New Midrange Aircraft, aka 797, is a mystery to one of the industry’s leading aviation consultants.
Richard Aboulafia of the Teal Group notes that Airbus’ research and development investment overtly disappears after 2018, with the introduction into service of the A350-1000 and the A319neo.
Aboulafia spoke at Day 2 of the Pacific Northwest Aerospace Alliance (PNAA) conference in Lynnwood (WA).
He’s long compared R&D spending between Airbus and Boeing, often praising the former for its level of investment and criticizing the latter for lagging.
Now, Airbus’ level of spending is a question mark while Boeing’s is a comfortable level compared with revenue, Aboulafia says.
Chinese and Russian Widebody takes shape. Part 5.

Introduction
February 12, 2018, © Leeham Co.: In the fourth article about the Chinese/Russian wide-body, CR929, we analyzed the engine selection for the aircraft. Now we continue with a first performance analysis of the CR929 against its main competitors, the Boeing 787-9 and Airbus A330-900.
We will use the preliminary data we have collected for the CR929 and compare this to the data for the 787-9 and A330-900. 
It’s the first analysis, on preliminary information. But there is enough knowledge of the key parameters to use our performance model to draw the first conclusions about the CR929’s positioning in the market.
Summary:
- The CR929-600 is modeled closely after the 787-9. The technology for structures, systems, engines and aerodynamics are similar.
- With a similar payload capacity, the fuel consumption should be better as the CR929 is defined with a lower maximum range.
- It’s wider cabin eats up the weight and drag advantage, however. There will be little difference between the efficiency of the 787-9 and the 15 years younger CR929.

Introduction
Feb. 5, 2018, © Leeham Co.: This will be an important year for wide-body sales in commercial aviation.
It would be overstating to say 2018 will be a pivotal year for wide-body airplanes, but there should be some important developments.
Summary
- Boeing may—or may not—launch the twin-aisle New Midrange Aircraft this year.
- Sales of the 777X remain stalled.
- Sales of the A330neo remain stalled.
- Airbus must decide whether to boost the production rate of the A350.
