August 24, 2023, © Leeham News: We have looked at the promises the VTOL industry made in their Investor prospects and what the reality is as the VTOLs come closer to Certification and production.
We started by using Joby and Archer as examples; now, we wrap the series by looking at some other top VTOL OEMs and how their claims have changed as the projects come closer to reality.

Summary:
- Joby Aviation and Archer are not alone in backpedaling on promised performance as certification nears; other OEMs that are investor-financed have the same problem.
- In summary, the VTOLs in the first generation can only fly short-range missions. Longer flights run into energy reserve and cost problems.
KMC’s “low risk” 777 P2F approach struggles to get traction

August 21, 2023, © Leeham News: Converting Boeing 777-300ER passenger aircraft to freighters has been fraught with challenges. One need only ask longtime P2F provider IAI, whose debut -300ER freighter has flown only once – nearly five months ago. Even Boeing shelved its own P2F plans for lack of a viable business case.

Kansas Modification Center (KMC), launched just two years ago, believes it offers a P2F concept with a smoother path to certification. KMC says its competitive edge is a forward cargo door, requiring less structural reinforcement and thus significant weight savings versus an aft door.
KMC believes it will receive FAA type certification by December 2024, with European regulator EASA expected to follow in early 2025.
LNA received a program briefing from Jorge Della Costa, KMC’s CEO, and Eric Kivett, program manager at contractor National Institute for Aviation Research (NIAR) WERX. NIAR WERX, a unit of Wichita State University, provides engineering and modification services for KMC’s forthcoming 777-300ERCF.
Summary
- Front loading door saves weight but may add loading challenges.
- Lead engineering partner brings prior conversion experience.
- Local partnerships, short supply chain reduce production risk.
- Certification risk mitigated by human factors planning, not modifying software.
- Lack of sales, capital are open questions.

We used our Aircraft Performance and Cost model to understand the data for the typical missions for the Joby S4 and Archer Midnight VTOLs and how the economics pans out for these missions. We now look at the results and compare them to what’s been projected from the OEMs.

Summary:
- We found the VTOL OEM’s economics for the typical 10-minute shuttle flights optimistic.
- When we go back and look at investor deck projections, the cost comparison to helicopter costs were totally off the mark. When we correct this the VTOL is more expensive to operate then an equivalent helicopter.
United selects GEnx for order for 100 787s

Aug. 14, 2023, © Leeham News: United Airlines quietly selected GE engines for its order in December last year for 100 Boeing 787-9s, according to Boeing’s website. The order isn’t finalized and neither GE nor United would comment.
There had been speculation that UAL might order Rolls-Royce engines as a mitigation for cancelling 45 Airbus A350-900s, which is powered exclusively by RR. United repeatedly deferred delivery of the A350s, which were ordered by previous managements. United inherited a large order for 787s when it merged with Continental Airlines and placed repeat orders for the 787 after the merger. The A350s essentially are duplicative to the 787s.
United placed large orders for the Airbus A321neo at a time when Boeing at first dithered whether to launch the New Midmarket Aircraft. UAL added to the neo order during the time when Boeing was unable to pursue any new airplane program due to the extended grounding of the MAX and during the COVID pandemic.

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.
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.

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.
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?
