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.
Pontifications: A little math for 777X, 737 MAX
By Scott Hamilton
Aug. 22, 2023, © Leeham News: We have a follow up to our Aug. 9 post about Boeing revealing the sub-type orders for the first time for the 737 MAX and 777X.
Boeing every month updates its website data for gross orders, cancellations and orders classified under an accounting rule called ASC 606. ASC 606 means orders are “iffy” for contractual or financial reasons with the customer.
The difference between gross orders and net orders represents cancellations, for whatever reason. The airline or lessor may have decided to cancel outright. Some orders might have been swapped within the family (for example, from a 737-8 to a 737-10). Some orders may have been swapped (cancelled) between models—for example, from the MAX to the 787. Boeing’s cumulative statistics haven’t revealed the difference between gross and net orders—until now.
ASC 606-classified order adjustments are excluded from the gross/net tally, Boeing tells me. In other words, for purposes of the tallies, the ASC 606 orders remain included in the gross numbers. They’re still orders at this stage, even if iffy. Airbus, operating under European accounting rules, doesn’t have to identify its iffy orders; LNA has made its best estimate for years of Airbus “iffy” orders, however, in an effort to level the publicly reported playing field. There are times when discussing orders and backlogs that we ignore Boeing’s ASC 606 classification when comparing with the Airbus orders.
With this as background, let’s get to the follow up to the Aug. 9 post.
KMC’s “low risk” 777 P2F approach struggles to get traction

By Judson Rollins
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.
Bjorn’s Corner: New aircraft technologies. Part 26. Airliner development program
By Bjorn Fehrm
August 18, 2023, ©. Leeham News: We started last week to look at how to make the development of a new airliner family more efficient.
First, we describe how development projects are phased and how many people with what competencies are engaged in each phase. Then we can start the discussion of what changes can be made and what would be the consequences.

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.
Pontifications: Off the beaten path museums
By Scott Hamilton
Aug. 15, 2023, © Leeham News: If you’re in the Puget Sound area (the greater Seattle-Tacoma region) and want to see some well-preserved airplanes that are off the beaten path, take a run down to the McChord Air Force Base south of Tacoma.
McChord was created before World War II. Through the decades, it’s been a fighter, bomber, transport, tactical and strategic base. Today, it’s home to only the Boeing C-17 cargo transport. Refueling tankers are inland at Fairchild AFB near Spokane (WA). Fighters are no longer at McChord; they are stationed at an air base near Portland (OR). (This is why I think McChord should be “BRACed” (declared surplus) and turned over for civilian use as a commercial airport, but this is another topic.)

I visited McChord last week to see its museum and its aircraft static displays. The museum is a small building with artifacts, models, photographs and history. As museums go, I’ve seen better, but there’s interesting information here that serves as a good introduction to the air park (called Heritage Hill) where 16 aircraft are located.
Embraer 2nd Quarter 2023 results show a positive trend
By Bjorn Fehrm
August 14, 2023, ©. Leeham News: Embraer presented its 2Q2023 results today. Commercial aircraft deliveries increased to 24 E-jets jets for 1H2023 compared with 17 E-jets in 1H2022, and Executive jets delivered 38 jets (29) in the period.
Revenue for the group increased by 24% to $2,009m ($1,620m) for the half year. The Services side increased revenue by 12.7% to $666m ($591m). The Defense revenue was 7.7% down at $180m($195m).
Half-year EBIT was $21m (-$263). The company retained the 2023 guidance, which means delivering 65-70 E-jets and 120-130 Executive jets during 2023.
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.
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?

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.
