Bjorn’s Corner: The challenges of airliner development. Part 25. Safety monitoring and reporting
By Bjorn Fehrm, Henry Tam, and Andrew Telesca
October 15, 2021, ©. Leeham News: Last week, we introduced the activities around Continued Airworthiness that we have to do during development and flight testing of our aircraft.
As described, the majority of accidents for aircraft are attributed to failings in Continued Airworthiness and Operations rather than design. We listed Continued Operational Safety, Operational Preparedness, and Service Readiness as the three important areas for Continued Airworthiness.
We dive into Continued Operational Safety first, specifically Safety Monitoring and Reporting.

Introduction
October 7, 2021, © Leeham News: In last week’s article, we could see today’s high cargo prices can motivate a 325 seat Airbus A350-900 even though the passenger load on the routes would point to a 240 seat A330-800.
How far does this “paying for a larger aircraft with belly cargo” paradigm go? Today we see if Airbus’ largest aircraft, the A350-1000, can generate the margins of the A350-900 on freight-rich routes. Can an airline that has an A350-900 sized passenger demand for such routes go to an A350-1000 instead?
Summary
- The increased yields for air cargo leads to surprising effects. Oversized passenger models can survive the passenger drought on today’s international routes as long as it’s a route with good freight demand.
Pontifications: Upping the game in eco Aviation
By Scott Hamilton
Oct. 4, 2021, © Leeham News: The pressure to reduce greenhouse gas emissions by the commercial aviation industry continues to increase.
Two weeks ago, Airbus hosted a day-and-a-half media event promoting its vision of moving toward decarbonizing aviation.
Boeing and Alaska Airlines last week hosted media for a touchy-feely event following up on the announcement in June by Boeing and Alaska of its joint ecoD (as Boeing calls it) program.
Boeing in October outlined progress of its ecoDemonstrator program, at the time with Etihad Airways as the partner. A 787-10 was used at that stage.
Mike Sinnett, Boeing VP of Product Development, said last week that the Alaska 737-9 MAX that is the focus of the current ecoD effort includes several ideas that would not make it into test on a stand-alone basis. But as part of a larger effort, little things that cumulatively can reduce drag and therefore fuel burn can be tested.
IATA AGM: Airplanes, engines SAF capable coming; feedstock lags by years

Introduction
Oct. 4, 2021, © Leeham News: Engine and airframe makers are well on their way to becoming fully capable of using Sustainable Aviation Fuel (SAF). But the industries providing SAF are way behind in meeting the potential demand.
Rick Deurloo of Pratt & Whitney
Rick Deurloo. Sr. VP & Chief Commercial Officer at Pratt & Whitney said one major US airline would use all currently available SAF in one day.
“The challenge will be the feedstock. How do we grow that technology or grow that ability to provide the feedstock so when we do have 100% SAF-capable aircraft and engines, we have the energy to go with it?” Deurloo said in an interview with LNA at the IATA AGM this week in Boston.
Airlines around the world are partnering with different companies to develop this technology, he said.
PW is already 50% capable and has a “clear path” to getting 100% capable within two years. But there is not enough feedstock in the world today do fill the 50% capability.

Introduction
September 30, 2021, © Leeham News: In last week’s article, we put the question: Has the increased cargo pricing started to affect the choice of airliner variant?
We analyzed Boeing’s 787-8 and -9 for margin generation when flying at low post-pandemic load factors. We found the 787-9 is the more attractive alternative as long as air cargo pricing stays high, even though the passenger load factor on the route would motivate a 787-8. The revenue from under the floor cargo compensates for a low load factor in the cabin. Now we subject the Airbus range; A330neo, and A350 to the same analysis.
Summary
- The trend from last week continues. Variants with high cargo capacity can sustain lower load factors while generating the same margin on routes.
- This article develops the passenger load factors where the margin generation is the same between Airbus widebodies.
Airbus begins “stuffing” A220 to speed assembly, cut costs

Sept. 28, 2021, © Leeham News: Airbus is streamlining some of its production of the A220 to reduce costs and the time to assemble the airplanes at its Montreal and Mobile plants.
Florent Massou, the SVP and Head of the A220 program, told LNA the company wants to shave 50% of the final assembly time for the A220. There will be an unrevealed cost reduction, which Massou declined to reveal. But he said it isn’t a one-for-one cost reduction.
Final assembly typically runs 5% to 8% of the total cost of the airplane, according to Boeing’s touch labor union, the IAM 751. Whether this equates to the A220, which began life as a Bombardier aircraft, is unknown.
Airbus’ TwoTwenty, its first real business jet
By Bjorn Fehrm
September 28, 2021, ©. Leeham News: When Airbus got the A220 airliner series from Bombardier, it also got the base for a competitive business jet.
Airbus, like Boeing, has produced Corporate Jets under its ACJ (Airbus Corporate Jets) since 1997 by converting its passenger A319, A320, A330, and A350 to one-off jets for Corporations, States, or wealthy individuals.
With the business jet based on A220-100, this changes. It’s no longer a one-off production but a fully-fledged Bizjet like the Gulfstream 650/700 or Bombardier Global 6500/7500, produced in series and with a semi-custom modular interior.

Airbus presents their CityAirbus UAM
By Bjorn Fehrm
September 21, 2021, ©. Leeham News: Airbus helicopter division presented their entry for the UAM market today at the Airbus 2021 Summit in Toulouse.
It was a presentation of a vehicle and ecosystem that has been cooking for years. After two demonstrators that tested different aspects of eVTOL flight and thousand of hours on supercomputers and in wind tunnels, the final CityAirbus is here, Figure 1.
Its configuration is as unique as Airbus’ approach when presenting it.

HOTR: Lockheed reveals tanker info: it’s all about America
Sept. 21, 2021, © Leeham News: Lockheed Martin (LMT) last week revealed its dedicated product launch web site page of 
the LMXT aerial refuel tanker. The LMXT uses the Airbus A330 MRTT as the platform for the US Air Force’s KC-Y competition for which initial information requests have been issued.
LMT and Airbus partnered in 2018 in anticipation of the KC-Y program, originally intended to replace the aging Boeing (nee McDonnell Douglas) KC-10. KC-Z was to follow, an entirely new concept in aerial refueling tankers.
KC-Y is now recast as a replacement for 140-160 Boeing KC-135s. It will be a follow-on to the original KC-X program, which was won by Boeing after three tries. Boeing has 179 orders for the 767-200ER-based KC-46.
Pontifications: 8-year old A330-300 converted to freighter, reflects weak market
By Scott Hamilton
Sept. 20, 2021, © Leeham News: An 8-year-old Airbus A330-300 was converted recently from passenger to freighter configuration by EFW.
Actually, says EFW’s Wolfgang Schmid, the airplane is not quite eight. It is the youngest A333 to be converted.
I can’t remember an airplane of any type this young being converted from passenger to freighter. The market value of an eight-year-old aircraft is way too high. Operating economics are well within airline requirements at this age. Aircraft historically become conversion candidates no sooner than 15 years of age and more commonly not before 20.
