Introduction
February 10, 2022, © Leeham News: Boeing introduced the freighter version of the 777X last week, and we made a first article about how it stacks up against Airbus’ new freighter, the A350F. The Boeing freighter will be the market’s largest freighter when it enters the market in 2027, two years after the A350F.
We now use our performance model to fly the new freighters against the present Boeing 777 freighter, the 777F, to look at their operating economics.
Summary
- Both new freighters handsomely beat the 777F on operating economics.
- The race is much tighter between the 777-8F and A350F.

Introduction
February 7, 2022, © Leeham News: The year that passed was when Sustainability broke through the walls of “I’m not convinced we have a problem” and “If so, what shall we do about it.”
The declarations ahead of, at, and after COP26 in Glasgow, United Nations 26’th climate conference, had many major states and organizations commit to targets for the reduction of Greenhouse gases by 2030 and 2050.
With this change in mind and traction, what can we expect to see in 2022 from the Air Transport industry?

Summary
- The years that passed were run-up years. Now the preparations shall lead to the first results.
- We summarize what we can expect to see during 2022.

Introduction
February 3, 2022, © Leeham News: Boeing launched the new large freighter, 777-8F, Monday with an order for 34 and options for 16 from Qatar Airways.
We made a comparison based on projected data in August 2021 of the 777-XF versus an A350 freighter, but now we have final data for both. We can now compare the 777-8F from Boeing with the A350F from Airbus. We also compare these with the present Boeing freighter, 777F.
The new freighters represent the largest freighters that will be in the market at the end of the decade, as Boeing’s 747-8F ends its production after the summer. The A350F starts deliveries during 2025, and the 777-8F joins in 2027.
We start with comparing freight capabilities, and then we fly them on a typical freight route, using our aircraft performance model.

Summary
- The 777-8F has the largest volume and highest payload capability, making it the market’s largest freighter at the end of the decade.
- But despite the highest takeoff weight, it has the shortest range of the compared freighters.
Year-end 2021 Orders at Risk
Subscription Required
By Vincent Valery
Introduction
Feb. 1st, 2022, © Leeham News: After a large number of cancellations, Boeing accumulated a healthy number of 737 MAX orders in 2021. Some came through positive ASC 606 adjustments on Boeing Commercial Airplanes’ website. The adjustments resulted from Boeing agreeing on new terms on existing deals or finding new customers for tails flagged as ASC 606.
Airbus also accumulated a healthy number of A320neo family orders, effectively selling out the production line through the middle of this decade. Both OEMs struggled with their twin-aisle order books due to the lingering effects of the pandemic and Boeing’s Dreamliner production problems. Freighter orders were a bright spot for Boeing.
However, portions of both OEM’s order books became shakier. It means there is a material probability some orders won’t translate into deliveries. Most were the result of airlines encountering financial difficulties, but some were related to contractual disputes. Boeing flags such orders as subject to an ASC 606 adjustment.
Unlike Boeing, Airbus isn’t subject to an accounting rule similar to the ASC 606 adjustments. Therefore, the European OEM does not break down the orders at risk of cancellation by the program. Airbus only discloses the nominal value of its total adjusted order book in its annual report.
LNA analyzed in July 2020, November 2020, and August 2020, Airbus’ and Boeing’s order books to identify orders at risk and come up with an apples-to-apples comparison. We update this analysis with the latest order books from both OEMs. The above links explain our methodology and its differences with Boeing’s ASC 606 adjustments.
Summary
- Lingering order book cleanup for older programs;
- A riskier region for single-aisle orders;
- Small and large twin-aisle order book weaknesses;
- A more significant impact on twin-aisle market shares.

Feb. 1, 2020, © Leeham News: GE Aviation appears confident the CFM open rotor engine—a concept that was flight tested back in the 1980s—is an engine whose time has come.
But it won’t be ready when the Next Boeing Airplane (NBA) is likely to be launched. Based on market intelligence, Boeing may launch its new airplane program in 2023 or 2024, for entry into service by the end of the decade. CFM’s open rotor, which it calls open fan, won’t be ready for application to an airliner until later in the 2030 decade.
Open rotors or open fans have the potential to be about 20% more fuel-efficient than today’s Pratt & Whitney Geared Turbo Fan or CFM’s LEAP engine. (GE is a 50% partner with Safran Aircraft in CFM.) The reduced fuel consumption results in a corresponding reduction in emissions. GE’s research and development program is called RISE, for Revolutionary Innovation for Sustainable Engines.
NIAR, partners offer tanker-converted 777-300ER PTF to US Air Force

Jan. 31, 2022, © Leeham News: A third company will offer a tanker to the US Air Force when the KC-Y Request for Proposal is issued this year.
Kansas Modification Center (KMC) and the National Institute for Aviation Research (NIAR) will propose converting used Boeing 777-300ERs to tankers. Jim Gibbs, president and CEO of KMC, already submitted information to the Air Force in response to last year’s Request for Information.

Gibbs, in an interview with LNA, said that the concept is to offer the Air Force a tanker not for front-line combat zones, but along the lines of the conversions used by Omega Air. Omega provides non-combat air refueling service for the US Navy, Air Force, and some NATO countries. It operates after-market conversions of the Boeing 707 and McDonnell Douglas DC-10. IAI Bedek also undertook after-market tanker conversions of the 707 and Boeing 767. The UK’s Royal Air Force converted Vickers VC-10s and Lockheed L-1011s to tankers.
Choosing the 777-300ER
Gibbs said the KMC and NIAR chose the 777-300ER over the 777-200ER or LR as the better platform, in their view.
“The 777, especially the -300, makes an enormous amount of sense right now. It’s a modern aircraft, very low time, the aircraft itself can haul about 200,000 pounds on a structural payload with very minor modifications to it,” Gibbs said. “You can take that aircraft, add some existing capabilities on it, such as the existing boom of KC-135, and simplify the fuel offload process. I think you would have a very capable tanker. If you have a mission radius of 3,000 miles, a 777 can still offload 150,000 pounds of fuel.
“The -300ER has a higher gross weight than anything, with the exception of the -200LR. If you look at the available aircraft for conversion and the available feedstock on it, the LR and the type of aircraft available for that are very minimal compared to the -300ER feedstock. The -300 is a bigger aircraft, it shares the same wing box and a lot of structure with the -200, or most of the structure, besides the plugs. We need to inject 100 tankers into the fleet. There’s not that many -200LRs out there,” Gibbs said.
Forecast 2022: ATR has monopoly, De Havilland looks to hydrogen and Embraer lurks with new design

Introduction
Jan. 31, 2022, © Leeham News: ATR is now effectively the only turboprop manufacturer outside of China and Russia in the 40-80 seat sector. The models are the ATR 42-600, ATR 42-600S (STOL), and ATR 72-600.
The series was built on simplicity with unpowered controls and the simplest possible systems. It has worked well for ATR when selling to markets that want airlift to the lowest possible cost. It also means the design is at its limits capacity and speed-wise, any more capacity or performance and it needs powered controls and more elaborate systems. It was behind ATR’s desire to develop a new, larger model in the past.
But ATR has little reason to develop a new turboprop now that it is in a monopoly position. This could change if Embraer proceeds with its concept for a new family of two turboprops, a 70- and a 90-seat aircraft. Embraer’s base design could form the basis of a hydrogen-burning gas turbine model in the future.

Jan. 27, 2022, © Leeham News: Despite vociferously criticizing Boeing over delays, technical difficulties and uncertainties over certification, delivery dates and performance, the president of Emirates Airline said the carrier is committed to the 777X.
Tim Clark said industry talk that Emirates may swap orders for the 777X for additional Boeing 787s isn’t correct.
Clark made his remarks in an interview with LNA on January 11. He also said he plans to retire within the next six months. Clark previously announced a retirement date but agreed to stay on to see Emirates through the pandemic crisis.
Summary
- “Boeing made life difficult.”
- Three-year delay has repercussions.
- The future of 777-8 passenger model is uncertain.
