Bjorn’s Corner: New aircraft technologies. Part 25. Efficient development
August 11, 2023, ©. Leeham News: We have described a number of technological advances that can be used to make the next-generation airliners more efficient and, thus, more environmentally friendly.
Part of developing more efficient next-generation aircraft is to change the development process to be more efficient. The last Boeing aircraft, the 787, took 7.5 years from launch to entry into service, and Airbus A350 took 8.5 years.
The target is to reduce this by up to 50%, but how?

August 10, 2023, © Leeham News: We look at the promises that the VTOL industry has made in their Investor prospects and what the reality is as they come closer to Certification and production.
After looking at claims of range and utility, we now look at the operating economics. We go through the different cost factors for a VTOL, add them up, and compare them with the industries’ projections.

Summary:
· The VTOL OEMs state their economics for 10-minute shuttle flights while claiming the VTOL can also fly flights four times longer.
· Yes, the VTOLs can indeed fly these longer flights, but then the economics fall apart.
Boeing reveals sub-type orders for MAX, 777X for the first time

By Scott Hamilton
Aug. 9, 2023, © Leeham News: Boeing yesterday revealed the orders for sub-types for the 737 MAX and 777X, the first time it has done so publicly.
The Seattle Times first reported the MAX detail.
The MAX data is largely similar to LNA’s estimates over the years, in which we analyzed the backlog, including Unidentified customers, to percentages. When the MAX 10 was program was launched, customers who ordered the MAX 8 or MAX 9 switched some of these to the MAX 10. Others have done so since then.
MAX orders remain concentrated around the MAX 8 and the high-capacity MAX 8 200, also known as the MAX 8200. Seventy-one percent of the MAX orders in backlog are for these two aircraft types. In contrast, 62% of the Airbus A320neo family backlog is for the largest model, the A321neo. Boeing’s direct competitor to the A321neo, the MAX 10, represents 19% of the MAX backlog.
The MAX 7 and MAX 10 have yet to be certified. Only the A321XLR remains to be certified of all the A320neo family variants.
Pontifications: Freighter outlook for the next 20 years
By Scott Hamilton
Aug. 8, 2023, © Leeham News: The cargo conversion market faces the prospect of oversupply of certain types, the consulting firm IBA said last week in a webcast.
The aftermarket conversion of Boeing 737-800s is already at 60 this year, according to IBA’s estimate.
Figure 1.
The forecast doesn’t extend beyond this year—and therefore is incomplete. IBA notes that the Airbus A321 P2F supply is a fraction of the 737-800 conversions, which are undertaken mainly by Boeing and aeronautical Engineers Inc (AEI). There are more than 100 A320 family conversions orders (all but a handful for the A321) that will be coming on line in future years.
Figure 2.
Likewise, IBA’s forecast for widebody conversions doesn’t extend beyond this year. There are also more than 100 orders for Airbus A330ceo conversions (all but a handful for the A330-300). Figure 2, like Figure 1, paints an incomplete picture.
Spirit Aero losses, cash burn continue

Aug. 7, 2023, © Leeham News: Spirit AeroSystems reported another loss-making quarter last week as more special charges in Airbus and Boeing programs.
Spirit is a major supplier to Airbus and Boeing. Airbus receives A350 fuselage panels, some A320 wing components and the A220 wings from Spirit. Boeing receives entire 737 fuselages and the nose sections for the 767/KC-46A, 777 and 787 from Spirit.
Spirit accumulated more than $2.8bn in operating losses and more than $3.5bn in net losses since 2019, the last full year before the COVID pandemic began in March 2020. The global fleet of 737 MAXes was grounded in March 2019 following two fatal accidents five months apart. Production of the 737 was suspended in the fall of 2019. Deliveries resumed 21 months later.
Deliveries of the 787 were suspended in October 2020 after Boeing discovered tiny gaps in the fuselage joins on aircraft and other, unrelated issues. One of the gap problems—no bigger than the thickness of a piece of paper—was traced to Spirit.
Quality control problems with 737 fuselages were discovered last year and with the vertical fin this year. All Boeing events resulted in charges.
A supplier in the A220 wing program declared bankruptcy and ceased operations, resulting in a charge. Charges were also taken in the A350 program as production was cut during the pandemic.
Airbus and Boeing advanced hundreds of millions of dollars to Spirit to help keep the company afloat. Spirit refinanced $900m in debt last year at an interest rate of 9 3/8%, at the time an above-market rate that indicates the risk factor banks view Spirit.
Bjorn’s Corner: New aircraft technologies. Part 24. Single or dual aisle fuselage?
By Bjorn Fehrm.
August 4, 2023, ©. Leeham News: This is a summary article to Part 24P. Single or dual aisle fuselage. It summarizes the drag and weight simulations we have done on fuselages for the next generation Heart of the Market airliners. When it comes to drag and weight for a 250-seat airliner that shall replace today’s Single Aisle, is a Single Aisle fuselage lower in drag and weight than a Dual Aisle fuselage?

August 3, 2023, © Leeham News: We look at the promises that the VTOL industry has made in their Investor prospects and the reality as they come closer to Certification and Production.
After looking at claims of range and utility, we now look at the operating economics. To do that, we need to predict the net sales price of these machines. We use our Aircraft Performance and Cost Model (APCM) to predict the production cost over time and, thus, the needed net sale price of the VTOLs.

Summary:
- The VTOLs are big; the Archer Midnight is the size of a nine-seater commuter aircraft (Figure 1). Aircraft costs are related to size and weight.
- VTOLs use aeronautical production methods and supply chains for parts and systems. The production costs are, therefore, predictable.
Pontifications: The see-saw remarketing of China’s 737 MAXes; Air India gets 55
Aug. 1, 2023, © Leeham News: Air India is taking 55 Boeing 737 MAXes originally built for Chinese airlines and lessors, LNA has learned. These are part of the order announced in February for up to 150 MAXes. The order was finalized during the June Paris Air Show.

This deal accounts for the sharp reduction in inventoried MAXes reported last week during the Boeing 2Q2023 earnings call. It also represents another development in the see-saw saga of whether to remarket the 140 MAXes built for China.
First, Boeing was going to remarket around 140 737 MAXes ordered by Chinese airlines and lessors but which remained in inventory due to Beijing’s refusal to authorize delivery.
Then, a mere three months later, Boeing CEO David Calhoun—who announced the remarketing effort in the first place—said Boeing would pause remarketing the aircraft.
Can airlines internally rapidly reduce CO2 and delays?

July 31, 2023, © Leeham News: Sustainable Aviation Fuel (SAF), battery- or hydrogen-powered airplanes, eVTOLS and Advanced Air Mobility vehicles get all the headlines when it comes to reducing emissions in commercial aviation.
One area that doesn’t get much in the way of headlines is improvement in the “day of” airline operation. Improvements in ATC or ATM receives most of the attention. But a “single” sky in Europe and “free flight” or “NextGen” Air Traffic Management (ATM) in the USA on the Air Traffic Control (ATC) side remain hypotheticals, largely because of funding and political issues, not to mention that airline delays, congestion and excess CO2 are not an ATC problem.
On the airline side, Alaska Airlines experimented with a software planning program called Airspace Intelligence that saved 2.7 minutes per flight. This doesn’t sound like much, and in the scheme of things, it isn’t. But this amounted to the equivalent of 17m miles driven by cars during the experiment.
But just how well are efforts working around the world that are currently underway to increase airspace and airport efficiency and reduce airline delays, congestion, cancellations, and excess CO2?
For the last four decades airlines and ATC have literally spent hundreds of billions of dollars on new equipment, new aircraft and new technologies. Yet little has changed. Airline delays, congestion, cancellations and excess CO2 happen over and over again.
Of course, the obvious question is Why – Why can’t the US Federal Aviation Administration (FAA) and other authorities solve this problem?
