Airbus Summit Showcases Sustainability Status
By Bjorn Fehrm
December 7, 2022, © Leeham News was at Airbus Summit: Airbus briefed media and influences on its Sustainability progress during briefings in Toulouse and Munich last week. Here is an update on where Airbus is with its programs.
The overall impression is of tangible progress on techno brick research and development and echo systems programs like SAF production and hydrogen supply and ground infrastructure.
At the summit, key customers like Airlines, technology partners, and leasing companies were part of the panels, giving the customer perspective and the view of the passengers.

HOTR: United likely can cancel A350 order with little penalty
By the Leeham News Team
Dec. 5, 2022, © Leeham News: United Airlines appears on the cusp of ordering as many as 100 Boeing 787s, multiple news outlets report. Airbus hopes to sell more A350s to United to supplement the 45 already on order.
But these 45 A350-900s are an order that has been viewed as iffy since United merged with Continental Airlines. Although ostensibly United was the surviving carrier, in reality, Continental was the survivor. The latter’s management displaced United’s old management. The livery retained was Continental’s.
The A350 order was placed by the old United management. The new executives added to the United order, but Continental had been an exclusive buyer of Boeing aircraft and executives were predisposed toward Boeing. UAL now has 120 Airbus A321XLRs on order. But this came after Boeing couldn’t decide whether to launch the New Midmarket Airplane after years of dithering. With a large fleet of Boeing 757s aging and in need of eventual replacement, United could no longer wait for Boeing to make a decision.
United already has a large fleet of 787s. Adding the A350s will provide an extra range that the 787s don’t have. But how many routes need the extra range to justify another fleet type?
LNA believes that United can cancel the orders for 45 A350s at little cost. The deposits may easily be applied to orders for more A321s, but cancellation penalties are believed to be de minimis. Based on 2018 list prices—the last ones published by Airbus—United could get about 110 more A321s in exchange for the A350s. (The number is probably a little less since the XLRs are more expensive than the A321neo “standard;” the list price makes no distinction between the sub-types.)
LNA expects United to cancel the A350s sooner than later and add to the A321 order.

Whatever the path chosen by the hundreds of companies seeking greener commercial aviation, government regulations and tax breaks are going to be a part of the solutions.
The airline industry has a goal of achieving net-zero carbon emissions by 2050. There are milestone targets between now and then. But will governments fully understand what’s technologically achievable in considering regulations or tax breaks? Will they fully understand which options are the best environmental solution?
Boeing developed an analytical tool called Cascade to help governments and regulators understand these issues. Importantly, Cascade takes into account the total life cycle factors for environmentally-friendly options.
The model analyzes carbon emissions for airplane fleet renewal, renewable energy sources such as sustainable fuel, hydrogen, electric propulsion, operational efficiency improvements, and advanced technologies. At the moment, Cascade remains in Beta testing internally. LNA has not had the opportunity to play with it.

“We’ve got to be honest about where we are on the life cycle emissions,” says Chris Raymond, the chief sustainability officer for The Boeing Co. “We’ve got to have a way to take that into account. We were just trying to start to illustrate to people that the energy generation upstream of whatever’s going to power the airplane is all part of the calculus that we have to think about. That’s really why we invented Cascade.”
Pontifications: A lost decade for new airplanes

Dec. 5, 2022, © Leeham News: In September 2020, LNA wrote that commercial aviation was facing a “lost decade.”
The impetus for this prediction was the COVID-19 pandemic crisis.
“Commercial aviation is facing a lost decade due to COVID,” we wrote. “Yes, most forecasts target 2024-2025 as returning to 2019 passenger traffic and aircraft production levels. However, LNA in July published its own analysis indicating full recovery may not occur until 2028.”
Nobody predicted that effective vaccines would emerge as quickly as they did. Drug makers in the US and Europe moved heaven and earth to produce vaccines to fight COVID-19. These have been, by and large, extremely effective. (I’ve had two shots and three boosters and have not caught COVID, despite being at one major conference with 13,000 people.)
China created its own vaccine, which failed to stem the tide there. President Xi quickly adopted total lockdowns at the first sign of outbreaks. Despite this, China is now setting records for new infections. Commercial aviation recovery there remains underperforming. China’s performance illustrates the underlying reasoning we had in concluding commercial aviation was facing a lost decade.
This sector still faces a lost decade, though for some fundamentally different reasons.
Bjorn’s Corner: Sustainable Air Transport. Part 48. eVTOL traffic management
December 2, 2022, ©. Leeham News: Last week, we started looking at the air traffic problem of eVTOLs. The rulemaking on how these shall avoid running into each other, other aircraft, and drones outside controlled airspace is not done.
The first general principle has been issued by European rule-makers dealing with how drone traffic shall be regulated, and this will also be expanded to cover VTOLs. Airbus, the world’s largest vertical transport supplier, through its helicopters, gave its view on VTOL operations in its two-day Summit this week.

Green aviation pressure applied to banks, oil companies, too

By Scott Hamilton
Dec. 1, 2022, © Leeham News: Pressure from environmentalists is prompting the aviation industry to move toward sustainable fuels.
But the pressure is not just on aviation. It’s also on bankers who finance airplanes and aerospace companies. These firms must show their shareholders, stakeholders and special interest groups that they are taking sustainability into account as they finance their customers.
The pressure is on oil companies, though many believe Big Oil isn’t really interested in cutting back its core business in favor of alternative energy.
In an interview with LNA, Chris Raymond, the chief sustainability officer for The Boeing Co., is frank about the challenges of meeting commercial aviation’s goal of achieving net zero carbon emissions by 2050. But he’s optimistic that the industry is on the right path.
It’s a path that’s been promoted before, with little success. In the first decade of the 21st century, the industry talked big but little activity occurred. In 2011, Jim Albaugh, then the CEO of Boeing Commercial Airplanes, predicted that 10% of fuel by 2020 would be Sustainable Aviation Fuel (SAF). The reality was that SAF accounted for 0.001% of the fuel.

Today, there are demonstration flights, including passenger-carrying flights, that used 50% SAF.
MTU gets support from Pratt & Whitney to develop the WET engine
By Bjorn Fehrm
November 29, 2022, © Leeham News: MTU and Pratt & Whitney presented an EU Clean Sky project today where they will develop an advanced engine concept based on the Pratt & Whitney GTF. The project is called SWITCH, an acronym for Sustainable Water-Injecting Turbofan Comprising Hybrid-Electrics.
There are participants from 11 countries in the project, among them Pratt & Whitney’s sister company Collins aerospace, GKN’s Swedish part, and Airbus.
The engine, which has a mild parallel hybrid architecture, extracts more energy from the turbofan fuel by driving the core exhaust through a vaporizer, where it recovers more heat from the core exhaust, Figure 1. Water from the exhaust, extracted from the core exhaust in a condenser, is heated to steam by the vaporizer and then drives a steam turbine that co-drives the fan. The steam is finally injected into the combustor to lower emissions.
The WET cycle will gain about 10% efficiency compared to today’s GTF. The concept also has a hybrid part which is primarily used for a low-emission taxi.

Nov. 28, 2022, © Leeham News: Boeing’s engineering corps could become further depleted within the next few days, as union-represented engineers and technical workers at the company’s Puget Sound plants face a Wednesday deadline on filing their retirement paperwork.
If they don’t leave now, individuals could face retirement benefit losses in the hundreds of thousands of dollars.
The potential loss of several hundred of Boeing’s most experienced engineers comes at a time when the company is scraping together engineering teams to tackle production problems in Charleston, and in the midst of an industry-wide shortage of engineering talent.

Pontifications: Airports and aviation or mass transit, conventional or high-speed rail
Nov. 26, 2022, © Leeham News: Some European countries declared war on the airline industry. Authorities in The Netherlands want to put permanent caps on operations at the Amsterdam airport. The French government wants to ban most airline flights of two hours or less within the country.
By Scott Hamilton
These two countries prefer requiring travelers to use trains vs planes. In the US, there are some on the East Coast who similarly advocate mass transit, more conventional rail and the creation of high-speed rail over short-haul flights operated by small regional jets.
Here in the greater Seattle area, forecasts conclude that there will be airport passenger demand for 97 million people by 2050. The region’s main airport, SeaTac International, has growth plans to accommodate 50 million passengers by then. Physical constraints prevent the airport from expanding. Just adding a third runway took 20 years and required a massive landfill to match the plateau topography on which the airport sits.
A task force recommends three sites south and southeast of SeaTac. Each is a greenfield site that is mostly farmland. Aside from the opposition from landowners over their properties being targeted, anti-aviation people are already suggesting creating more conventional and brand new high-speed rail alternatives.
But, like so many advocating battery-powered airplanes and eVTOLs, or hybrids, or hydrogen-powered aircraft, those advocating substituting rail for airports ignore all the costs—both financial and otherwise—that go into a rail system.
Let’s take a look.
Bjorn’s Corner: Sustainable Air Transport. Part 47. eVTOL traffic
By Bjorn Fehrm
November 25, 2022, ©. Leeham News: We have gone through the flight principles for different eVTOLs, the critical systems such as battery systems and flight controls, their energy consumption/performance, and how green they are compared to other ways of getting to an airport.
This is all about the flying vehicle. But it’s only part of the system needed for this transport system to work and be safe. We now discuss the other bits needed.
