Paris Air Show: Qatar and others
Subscription required.
Introduction
June 1, 2015, c. Leeham Co. It could be called the Qatar Airways Air Show.
Qatar Airways plans to have five airliners on display at the Paris Air Show in two weeks: the Airbus A319, A320, A350, A380 and the Boeing 787. The carrier hasn’t 
announced whether it will provide an aerial display as it has at previous air shows, but Qatar may well have more airliners there than Airbus or Boeing.
As for manufacturers other than Airbus and Boeing, we don’t expect anything of consequence from these.
Summary
- Irkut, COMAC, Mitsubishi, Sukoi and ATR are other major aircraft producers that will be at the Paris Air Show.
- Engine makers CFM International, GE Aviation, Rolls-Royce, Pratt & Whitney and Engine Alliance will also be there.
- An update on Airbus expectations.
Bjorn’s Corner: Airbus Innovation days, activities and program updates.
By Bjorn Fehrm
Introduction
28 May 2015, C. Leeham Co: I am in Toulouse today attending Airbus Innovation days for Leeham News. It has been a good day’s briefings and I have presented what was perhaps the biggest change since we last met Airbus in the article “Airbus A350-1000 getting real”.
Apart from this program, there were more standard updates on Airbus other activities and programs. Here follows a rundown on these updates in a more paraphrased form.
The higher level game
By Bjorn Fehrm
Introduction
May 4, 2015, c. Leeham Co. The other day one of our readers asked something along the lines, “now that Airbus has the A320neo 20% more efficient than today’s A320, how shall Boeing’s 737 MAX fair in the market? It is only 15% more effective and there are question marks around the LEAP-1B?”
This made me realize that marketing works. I decided to write about the phenomenon that the OEMs seem to find further improvements all the time and how these continually higher improvements seem to work beyond the physical laws as we know them.
The answer boils down to the fact that there is more than meets the eye around how much fuel an aircraft uses to transport people from A to B. In fact, the OEMs’ marketing departments excel within the complexity of the task and can always find a way to say “my mousetrap has now improved another x% and is therefore Y% better than yours”.
To cut through these marketing moves one need a bit of background and first grade math. Let’s see how they do it. Read more
Paris Air Show Preview: Airbus
Subscription Required.
Introduction
May 3, 2015, c. Leeham Co. The Paris Air Show is June 15-19 for the trade/industrial portion. Beginning this week, Leeham News and Comment will provide our 
Market Assessment and insight about what to expect. We begin this weekly exercise by looking at Airbus. Future posts will look at Boeing, Bombardier, Embraer and other major players at the PAS.
Summary
- First, an overarching look at what to expect;
- What to expect for Airbus at the show;
- The future of the A380neo;
- Outlook for the A330ceo/neo; and
- Outlook for the A321LR.
Can PIPs bring the A380 what Emirates Airlines wants?

Introduction
26 April 2015, C. Leeham Co: With Emirates Airlines deciding for Rolls-Royce Trent 900 engines for its 50 new A380s and admitting that it would accept that this could be for all of them if Airbus does not proceed with an A380neo, the time has come to look at how much incremental improvements can be brought on the present A380.
Our proprietary aircraft model is particularly suited for such studies as we can change any parameter and read the result off the efficiency scale. We can also play with the aircraft’s configuration and see what effect it will have. Based on Emirates’ new configuration of A380s equipped with the Trent 900 engine, we have checked what incremental improvements are doable and what would they bring.
Summary
- Our deep analysis of 18 Dec. 2014 showed that the present A380 is the most economical aircraft one can operate if one can fill it to normal load factors.
- Emirates COO Tim Clark complements this fact with the statement, “It is Emirates’ most profitable aircraft” in the press conference in London last week when announcing the Trent 900 deal with Rolls-Royce.
- Clark’s statement also covers the fact the passengers prefer A380 over other aircraft if they have a choice, it operates with higher load-factors then Emirates other aircraft.
- The A380 is a rather special design and its characteristics make Product Improvement Packages, PIPs, possible in a number of areas. We discuss which they would be and model their effect on overall performance.
- While the sought-after 10%-13% improvement would not be in there, incremental changes can cover up to half of that with more or less plausible business cases. Airbus is right now deciding which of these they see as worthwhile and introducing them.
Aviation Partners Boeing: next step–scimitar for 757, 767

Introduction
April 14, 2015: Several airlines operate the Boeing 757 across the Atlantic on “thin” routes but sometimes have to do refueling tech stops when high westerly winds

occur.
The 757s are aging, with engine maintenance, repair and overhaul costs increasing under the tightly-controlled contract with Rolls-Royce and Pratt & Whitney.
Some airlines want a “757 replacement.” Boeing and Airbus don’t see a market for “just” a 757 replacement and argue the 737-900ER/9 and A321neo/LR are the replacements. Even these fall somewhat short.
Industry observers and pontificators nonetheless are obsessed with a “757 replacement” (except us—we’ve redefined the replacement as one needed for the 225/5000 Sector [225-250 seats, 5,000 miles] and concluded an airplane very similar to the 767-200 is needed).
Patrick La Moria, EVP and chief commercial officer, Aviation Partners Boeing.
While all this debate is going on, Aviation Partners Boeing (APB) is close to seeking board approval to offer a scimitar option for the 757 that will improve efficiency by about another 1.5%. A scimitar for the Boeing 767 may not be far behind.
Summary
- Scimitars and the increased range will eliminate some “tech” stop for fuel.
- Field performance will be better.
- Low fuel prices and prospect of scimitars (as well as lack of availability of new airplanes) may lead to longer retention of 757s and 767s.
2030 decade airplanes need new shapes for better efficiency

Now open to all readers.
Introduction
April 6, 2015, c. Leeham Co. The next 15 years may well be the last new airplane programs of major airliners that look like today’s tube-and-wing aircraft because demands for new efficiency will require go beyond what engines can do within a reasonable size, says Alan Epstein, VP of technology and environment at Pratt & Whitney.
- Part 1 of our interview with Alan Epstein looked at the next new airplane, the Middle of the Market aircraft (MOM). Today’s Part 2 looks beyond MOM (and it’s not DAD).
Major changes to the airframe will have to provide added efficiency gains in combination with new and evolving technology from today’s engines.
The next new airplane, the so-called Middle of the Market (MOM) aircraft, will look like today’s airplanes. The next plane after that, the replacements for the Airbus A320 and Boeing 737 families, will probably be the last iterations of the planes of today. After that, new designs are likely to emerge, Epstein says.
Summary
- Tomorrow’s airplanes need to revise the fuselage design to increase efficiency.
- Airplanes after 2030 may look different than the tube-and-wing configurations of the past decades.
- Four engine airplanes may make a return.
