Pontifications: For Boeing, the future is a new airplane, not the status quo
By Scott Hamilton
Feb. 22, 2021, © Leeham News: Tunnel-vision pundits, analysts, and even some experts say Boeing shouldn’t launch a new airplane program within the next few years.
Why? They say doing so will cannibalize the 737 MAX 9 and MAX 10. They say it will undermine sales of the entire MAX family.
I say, poppycock.
Boeing has a MAX problem. It’s not the grounding, although the issues from this are obvious. LNA has written about this ad nauseam, but it’s necessary to remind these new airplane-naysayers. The MAX 7 is a sales dud. The MAX 9 isn’t far behind. And the MAX 10 is uncompetitive with the Airbus A321neo family.
The only MAX that has a bright future is the MAX 8. Boeing can’t rely on the MAX 8 for its future in the 125-240 seat sector.
Differentiation in the marketplace and the time for the open rotor

Introduction
Feb. 22, 2021, © Leeham News: Airliners are now so efficient, one challenge facing Airbus and Boeing in competing is overcoming the laws of diminishing returns.

LNA described this challenge Feb. 8. Additionally, airport infrastructure erects a vast number of design roadblocks.
We focused on the creation of the 737 replacement and how difficult it will be to make meaningful performance upgrades to the economics of the vehicle. We outlined the next battle in product differentiation most likely will occur in optimizing non-flying time operations, focusing on ground operations as the next efficiency battleground. Since then, it was reported that Boeing indicated that a new aircraft sized between the 737 and the 767/NMA was a front runner in their future planning.
Summary
- NMA Lite needed for 737-9/10 to 787-8 sector.
- Replacement for 737-7 and 737-8 best suited for Open Rotor design.
- What an Open Rotor plane might look like
Bjorn’s Corner: The challenges of hydrogen. Part 25. Auxiliary power
By Bjorn Fehrm
February 19, 2021, ©. Leeham News: Last week we discussed hydrogen aircraft propulsion and found a shaft power producing gas turbine was considerably more weight-efficient than a fuel cell powering an electric motor. Both had the same 55% shaft power efficiency.
Will a gas turbine APU burning H2 be the best choice for auxiliary power as well?

Airbus 2020, prudent navigation of a challenging environment
February 18, 2021, © Leeham News: Airbus presented its results for 2020 today. The company reported a net loss of €0.5bn at revenues of €50bn (€70.5bn 2019). Airbus’ operations delivered a result of +€1.7bn; it was then reduced to a loss by charges of €2.2bn for the year.
Airliner deliveries reduced by 34% to 566 for the year (863), with net orders at 268 aircraft (768). A forecast for 2021 was given as same-level deliveries with operating profit at +€2bn and break-even Free Cash Flow.

Introduction
Feb. 18, 2021, © Leeham News: After comparing the Airbus A350-900 and the Boeing 777-200ER on a long haul route, we turn our attention to the A350-900 Ultra Long Range variant.
Summary
- A history of Ultra Long Haul Flights;
- Proliferation along with globalization;
- Poor sales record of ULR variants;
- The attractiveness of the A350-900ULR.
Built for Mars

Feb. 17, 2021, © Leeham News: Ever since watching the movie and reading the book, The Martian, I’ve been fascinated about all things Mars.

Previous movies were contrived sci-fi trash. The Martian was fiction, to be sure, but it was science-based. A NASA official told me the agency cooperated with the book author and the movie producers. And John Shannon, the lead of Boeing’s giant SLS launcher for a Mars mission, also told me the book and movie were based on science.
NASA and Boeing in 2016 outlined some of the challenges in this powerpoint.
Built for Mars is a 90 minute chronicle of NASA’s current mission to Mars. The Perseverance rover is the first of three missions over 10 years to return samples from Mars to Earth for scientific study. Produced by National Geographic and premiering Feb. 18, the challenges of putting together this mission are immense.
Podcast: 10 Minutes About Sustainable Air Transport
Feb. 16, 2021, © Leeham News: Electrically powered aircraft. Or hybrids. Or bio-fuels. Or hydrogen.
These are the alternative suggested by environmentalists and industry to reduce carbon emissions by the airlines.
Which makes sense? Which is practical? Today’s 10 Minutes About considers these factors.
Airbus’ production plans

By Vincent Valery
Introduction
Feb. 15, 2021, © Leeham News: LNA wrote last month an article about Boeing’s latest production plans for future years. Airbus announced updated production plans on Jan. 21.
Airbus’ latest production plans call for a shallower increase in A320 production rates than envisioned earlier due to the lingering effects of the COVID-19 pandemic. The A220 production rate will go back to five per month, while twin-aisle rates will stay flat for the foreseeable future. Airbus postponed an envisioned A350 production rate hike while predicting a return to pre-COVID demand levels by 2023 to 2025.
These updated delivery rates reflect customer’s delivery preferences. Ahead of Airbus’ earnings release on Feb. 18, LNA analyses the revised delivery schedule for coming years on the four major commercial programs.
Summary
- Some A220 delays;
- Slight A320 adjustments;
- Lower for longer on twin-aisle programs;
- Near-term delivery concerns on one program.
Pontifications: The New Air Force One: Flying Fortress
Feb. 14, 2021, © Leeham News: Air Force One is, after the national flag, the most recognizable and prestigious symbol of the United States.
By Scott Hamilton
It’s also shrouded in mystery.
A new National Geographic special premiering Feb. 15 lifts the veil, at least partially.
NatGeo was granted unprecedented access to the development of the new airplanes, two Boeing 747-8s, that will replace the 30-year old 747-200s that serve as Air Force One.
Bjorn’s Corner: The challenges of hydrogen. Part 24. Propulsion choice
By Bjorn Fehrm
February 12, 2021, ©. Leeham News: After covering the basics of fuel cells last week in our hydrogen airliner series, we now look at what type of system to choose for aircraft propulsion and onboard systems power.
We analyze the propulsion side this week.
