Introduction
08 March 2015, c. Leeham Co: In the third part of the article series around the need for a more capable solution for 180-240 seats and 5,000 nautical miles, we compared different clean sheet single and dual aisle aircraft to the Airbus A321LR and Boeing’s 787-8, the two aircraft that form the border to the segment.
We could see that a single aisle aircraft started to have trouble with weight at around 220 passengers using our normalized seating rule set. This would with normal OEM seating rules be around 230-240 passengers. At the same time the dual aisle aircraft becomes stronger the more seats one assumes. The reason is their thicker fuselage, Figure 1, lends itself better to aircraft which passes 50 meters/160 feet in length.

Their advantages in boarding and deplaning then starts to outweigh their disadvantages in weight and drag. This trend is explored further in this part where we add Cash Operating Cost, COC and Direct Operating Cost, DOC, to the analysis.
Summary
- The trends seen for NAS6, NLT6 and NLT7, our Middle Of the Market, MOM, models in the segment 180 to 240 passengers gets further reinforced when we go to COC and DOC.
- A factor supporting this is the broader spread of fixed and semi-fixed costs over larger aircraft seat numbers.
- Another is that the shorter ground turn-around time for dual aisles increases the utilization for the aircraft, once again forming a broader base for fixed and semi-fixed costs.
- Introducing CFRP for the fuselage brings clear gains in weight and therefore operating costs. Key for its inclusion in the MOM designs will be the manufacturing advances that will have been made by 2025.
Pontifications: Boeing cracks open door to 777 production rate cuts (or not)
By Scott Hamilton
March 8, 2015: Boeing cracked open the door March 5 to a production rate reduction on the 777 Classic, the first time since launching the 777X in 2013 that officials have publicly deviated from their insistence the current rate of 8.3/mo can be maintained to entry-into-service of the 777X.
At least that’s how I see it. Boeing sees it differently. Boeing says nothing has changed in its messaging.
In an appearance at the JP Morgan Transportation Conference, Greg Smith, EVP of Business Development and Strategy and Chief Financial Officer of The Boeing Co., Smith appeared to back away from the Boeing messaging to-date that has been all (to paraphrase) “We’re confident we’ll bridge the gap,” “We have three years of backlog and six years to bridge the gap”, “We’re confident we’ll maintain production at the current level,” etc, etc.
At least that’s how an aerospace analyst for a New York firm expressed it when he called me. After listening to the event, I agree with the analyst.
In the recorded playback of the JP Morgan event, here’s the report of Smith’s comments starting at 9:36 into the presentation.
Pontifications: A350 launch aid, Emirates and the A380, Bombardier and U-Turn Al
By Scott Hamilton
March 5, 2015: A350 Launch Aid: Boeing and the US Trade Representative got in a big twist around 2006 when Airbus said it would accept more than $1bn in launch aid from Germany for the A350. At that time, the US and European Union had recently launched the international trade complaints before the World Trade Organization (WTO), but the A350 came after the complaint was filed and the WTO refused the US request to add it to the proceedings.
Germany, in a political snit, later said it would withhold part of the launch aid because Airbus hadn’t promised the number of jobs in connection with the program to Germany that politicians wanted.

Introduction
04 March 2015, c. Leeham Co: In the first and second part of the article series around the need for a more capable solution for 180-240 seats and 5000 nautical miles, which we have labeled the 225/5000 Sector, we went through the derivatives we have analyzed as competitors to Airbus A321LR and showed why none of them are effective as a Boeing solution.
We also looked at the wetted area and weight for our common single and dual aisle aircraft. These parameters are the principal components that determine an aircraft’s efficiency given a certain engine efficiency. We also developed the market picture, outlining a substantial market by the time of entry into service of a clean sheet design by 2025, given that certain market requirements could be fulfilled.
We will now project different solutions to the requirements, thereby utilizing the preliminary design part of our proprietary aircraft model. We will look at three different cabin configurations in four different size classes between 180 to 240 seats and calculate size and weights and the resulting efficiency of the different variants. Against the key data for these different aircraft and their operational efficiency we will be able to postulate what will be the next move from Boeing and Airbus in this segment.
Summary
The findings in this our third article include:
- Aircraft capacity and size for 12 different possible aircraft, named NAS6, NLT6 and NLT7 each in the variants 180, 200, 220 and 240 passengers.
- With this collection of characteristics it will be possible to compare the efficiency and costs for the different sizes and to see how competitive a wider dual aisle aircraft will be in this segment compared to a single aisle.
- In a subsequent article will be compare the operational characteristics of these aircraft thereby also covering the increased revenue potential with a dual aisle aircraft compared to a single aisle.
Production rates on single-aisles keep going up, up

Introduction
March 3, 2015: c. Leeham Co. Production rates for single aisle airplanes continue to go up for the Big Two, following the Airbus announcement last week that the A320 rates will go to 50/mo in 2017 and officials are considering going to more than 60/mo.
We’ve previously reported that Airbus already has notified the supply chain to be prepared to go to 54/mo in 2018.
Rate 50 will propel Airbus ahead of Boeing, which will briefly be ahead of Airbus when the 737 production rate goes to 47/mo next year, compared with the Airbus plan to take A320 rates to 46/mo next year. The two companies are at parity this year. (Figure 1.)
Summary
- Bombardier, COMAC and Irkut add to supply by 2020, but impact will be minimal.
- No 747-8 deliveries scheduled in 2018. We see program termination coming very soon.
- A330ceo production rate reduced, higher rate for 787 than announced.
- We see short-term Airbus advantage coming in wide-body production rates as A350 ramps up. We stick with our call that 777 Classic rates have to come down.
- We reduce A380 production rates in our estimates.
Exclusive: CSeries performance better than guarantees, “favorable” to brochure; range better than advertised
Rob Dewar, program head of the Bombardier CSeries.
March 3, 2015: c. Leeham Co. Flight test results for the Bombardier CSeries show that the economics of the airplane not only are meeting the economic and performance guarantees, they are “favorable” to the marketing brochures that have promised 15% better operating costs and 20% better fuel burn than today’s in-production Airbus A319s and Boeing 737-700s, Leeham News and Comment confirmed.
Three sources told us the CSeries flight tests were turning in better-than-guarantee results. Rob Dewer, vice president and general manager, CSeries Program, confirmed the information today in an exclusive interview.

Introduction
01 March 2015, c. Leeham Co: In the first part of the article series around the need for a more capable solution for 180-240 seats and 5,000 nautical miles, we went through the derivative aircraft that Boeing could field as competitors to Airbus A321LR and showed why none of them are effective. We also established the market requirements and the likely market size for aircraft that shall cover this segment and the required efficiency and overall cost improvement needed.
We will now look at different solutions to the requirements, first by analyzing what key characteristics does single and dual aisle aircraft have and what consequences will they have for the aircraft’s efficiency parameters like weight, size and drag. Once we have these characteristics we can design adapted aircraft types and calculate their economics such as fuel costs and other costs and we can also establish their operational ground handling times and thereby the consequences single or dual aisle will have on the aircraft utilization.
Having developed and presented these facts it will be possible to forecast what will be the most likely results of Boeing’s New Airplane Study, NAS that we presented 2 November last year. Boeing now uses the name, Middle of the Market (MOM) in place of the NAS.
Summary:
Our second article shows:
- Drag and weight per seat for today’s short and mid-range aircraft vary significantly between single and dual aisle aircraft
- There is a strong correlation between aircraft wetted area and aircraft weight.
- Dual aisle designs in the 180-240 seat segment will have to be highly optimized to be able to compete with single aisle, if at all.
CS300 first flight

The first flight of the Bombardier CS300, the 149-160 version of the new generation aircraft, came off without a hitch on Feb. 27. The flight lasted five hours.
The CS300 is a direct challenge to the Airbus A319ceo/neo and Boeing 737-700/7 and comfortably outsells the A319neo and 737-7. The economics of the CS300 are substantially better than the Airbus or Boeing, according to Bombardier claims and validated by our analysis.
This CS300 is Flight Test Vehicle 7 (FTV 7) but actually precedes FTV 5 and FTV 6 into the BBD test fleet.
Trip report: flying the A350 to Airbus Group annual press conference
By Bjorn Fehrm
Introduction
Feb. 26, 2015: As part of the invitation to cover Airbus group press conference in Munich on Feb. 27 where the annual results are presented, Airbus offered the journalists joining from South of France to fly there in one of the A350 test aircraft, the cabin test specimen MSN002. They did not have to ask twice, Figure 1.

The flight was done as a combined transportation of media from Toulouse and Paris to Munich and test flight for the cabin area. It was also the first time A350 landed on Charles De Gaulle (CDG) and Munich airports, which added to the excitement. The aircraft still carried full test equipment and there were measurement probes on windows and different parts of the cabin.
The crew was the normal test crew reinforced with Airbus cabin personnel who cared for the attending journalists. The advantage of this was there was plenty of time to talk to the test engineers and pilots both in flight and while waiting for joining media at CDG. Here the story of the development workday for test people where the actual aircraft has just entered service with the first customer. But first how it was to fly: Read more
