Pontifications: Mississippi’s aerospace footprint
By Scott Hamilton
July 17, 2017, © Leeham Co.: Living in the Seattle area, the highest profile, dominant industry is the commercial aerospace sector.
Boeing, of course, headlines just about everything when it comes to aviation.
Boeing’s competition is principally Airbus—or at least it used to be until Boeing claimed teeny tiny Bombardier, a company one-sixth the size of Boeing’s revenues, is poised to put Boeing out of business with BBD’s CSeries.
A380Plus: First analysis, Part 2

July 10, 2017, ©. Leeham Co: We went through the changes that are included in the Airbus A380Plus development study last week.
The study packages several improvements to the A380, improving the aerodynamics, increasing the passenger capacity and lowering maintenance costs.
The aim is to improve the cost per seat of the A380 to keep it competitive with the new Boeing 777-9. With the rundown of the improvements complete we now use our aircraft model to see if the cost per passenger can compete with the 777.
Summary:
- The A380Plus improvements makes the A380 competitive on Cash Operating seat mile Costs with the Boeing 777-9.
- The problem on how to fill the 70% larger A380 remains. It needs other solutions.
Qantas’ ultra-long haul dream, Part 3

Introduction
July 06, 2017, © Leeham Co.: In previous articles we have learned how to fly the challenging route Sydney-London direct. From a well-informed person in Qantas we learned not to fight the winds. We shall use them. If we fly intelligently we put a cap on the longest distance we fly, even on windy days.
The other way around, London to Sydney, is less of a challenge. The aircraft is blown down under by the winds.

Now we use our aircraft model to understand how Airbus’ A350-900ULR and Boeing’s 777-8 would cope with the route.
Summary:
- The ideas of Qantas did not stop with not fighting the winds.
- We also learned how to simplify the analysis process for URL aircraft and routes.
- Forget about cabins, seats and passengers. It’s all about the hauled weight.
MC-21 and C919 compared. Part 3.

Introduction
June 15, 2017, ©. Leeham Co: We continued the comparison of Irkut’s MC-21 and COMAC’s C919 last week with an analysis of the cabins and systems. The week before, we compared project time plans, structures and aerodynamics.
Now we finish with an analysis of the economics of the aircraft.
Summary:
- The MC-21 is the more advanced aircraft of the two. It uses carbon composites for the wings and empennage.
- Coupled with more refined aerodynamics, the MC-21 offers a higher efficiency than the more classical C919.

Introduction
June 08, 2017, ©. Leeham Co: We started the comparison of Irkut’s MC-21 and COMAC’s C919 last week. We compared project time plans, structures and aerodynamics.
Now we continue with the comparison of cabin capacities and systems.
Summary:
- The C919 cabin is a slightly longer copy of the Airbus A320 cabin. MC-21 sets new standards for cabins in the single aisle segment.
- Both aircraft use Western systems to ease development and improve in-service reliability.
Paris Air Show Preview

Introduction
May 22, 2017, © Leeham Co. The Paris Air Show begins June 17, and few in the industry expect much in the way of orders this year.
The order cycle is on the downward side of the bell curve. Sustaining the 2,000, 3,000 or nearly 4,000 gross orders announced 2011-2013 simply couldn’t be achieved. The “order bubble” had to break, and it did. Last year, Airbus and Boeing reported some 1,400 orders between them.
Airbus guides that it will tough to achieve a 1:1 book:bill this year. Boeing is running about 1:1 book:bill so far but it also guides conservatively. Still, LNC thinks Boeing might surprise this year–and some of this could be at the Paris Air Show.
Leeham Co.’s new publication, Commercial Aviation Report, provides a Focus Report on the Air Show. This encompasses the expectations for Airbus, Boeing, Bombardier, Embraer, COMAC, Irkut, Mitsubishi, CFM, GE Aviation, Pratt & Whitney and Rolls-Royce into one easy-to-read package.
The pre-airshow press briefings by the OEMs begin next week. We don’t expect any earth-shattering news from these and we wanted to get our views out ahead of these briefings.
Summary
- Boeing wants to launch the 737-10 MAX at the Paris Air Show. This could spur a group of orders that would give Boeing a rare win in the headlines vs Airbus on the latter’s home ground.
- Mitsubishi plans to have its MRJ90 at the Air Show. One airplane entered the paint shop for ANA colors–this might be the one making the appearance.
- Embraer expects to have its KC-390 there. Will the E195-E2 also make an appearance?
Regional aircraft for US Scope clause operations. Part 3.

Introduction
May 18, 2017, © Leeham Co.: In the second article about the US regional aircraft market, we looked at the cabins for the regional aircraft we examine. We started with looking at the typical classes and their seat ratios for the mainline aircraft the regional aircraft are feeding to/from. Then we mimicked that on the regional aircraft.
We filled the cabin with domestic First-class seats, then Premium economy and finally Economy until we got 76 seats or the cabin said stop.
Now we complete the picture by comparing the economics of the aircraft after which we summarize our findings.
Summary:
- The benchmark aircraft for the US scope clauses is the E175 from Embraer. It was designed for the scope clause market.
- It’s larger dimensions means the operating costs are slightly higher than the CRJ900.
- A scope clause-bound operator can compensate the Bombardier CRJ900’s tighter cabin with more seat pitch. It has the longest cabin of all compared aircraft.
- The MRJ70 and CRJ700 are too short for scope clause flying with 76 seat cabins and the MRJ90 is too heavy for the 86,000lb maximum weight limit.
How Airbus can kill the Boeing 797

May 10, 2017, © Leeham Co.: Airbus can kill the business case for the prospective Boeing 797, the New Midrange Aircraft also known as the Middle of the Market Airplane,
- Reuter’s Tim Hepher has this story.
- CNN’s Jon Ostrower has this story.
All it has to do is move first, instead of waiting for Boeing to launch the 797, something considered likely next year.
If Airbus launched what is commonly called the A322, a larger, longer-range version of the A321neo, the new version would become a true replacement for the Boeing 757, meet economics of the smaller 797, which has a working title of the 797-6, at a much lower capital cost.
Boeing’s BHAG: Is $50bn Service Revenue Goal Achievable?
Special to Leeham News and Comment
By Kevin Michaels, Managing Director, AeroDynamic Advisory
Business gurus Jim Collins and Jerry Porras coined the phrase “Big Hairy Audacious Goal” (BHAG) to describe a business objective which is highly ambitious,

galvanizes the organization, and is often met with skepticism from outside observers. Boeing recently created a BHAG that could transform aerospace MRO. Its goal is to triple its service revenue to $50bn within the next decade, and it is taking decisive action achieve its vision.
Could an NMA be made good enough? Part 5

Introduction
April 20, 2017, © Leeham Co.: After defining the fuselage and wings, it’s now time for the engines. We go through the sizing criteria for engines for airliners and find the size of engine that is needed for the NMA.
The NMA will need engines which are larger than the single aisle engines for Airbus’ A320neo and Boeing’s 737 MAX. But they will be smaller than the next size up for modern engines, the GEnx-2B for Boeing’s 747-8.
Figure 1. The NMA takes more and more the shape of a 767 replacement (A United 767-200). Source: United
This means the NMA will need new engines, at least 50% larger than the present engines designed for A320neo and 737 MAX.
Summary:
- An NMA engine will be sized by V2 safety speed or Maximum Continuous Thrust (MCT) criteria.
- The normal Top of Climb (ToC) sizing point will be less stressing for a twin engine airliner like NMA.
