Introduction
June 23, 2022, © Leeham News: What is the best business: to transport cargo below the floor in passenger airliners or with dedicated freighter aircraft?
We could see in last week’s article that air freight companies have generally been more profitable over the last decade than passenger airlines. Why?
We continue the analysis by looking at the cost of flying cargo in passenger airliner bellies versus dedicated freighters.
Summary
- At today’s high fuel prices, transporting cargo in a passenger aircraft’s belly is cheaper than on freighters when we do a first-level analysis.
- Does this change when we go deeper?
Commercial Aircraft programs duration from launch to delivery over the years

Introduction
June 20, 2022, © Leeham News: New airplane programs used to come to market in four years. Now, the launch-to-entry-into-service period has been seven years or more. (Chinese and Russian programs take even longer.)
Boeing launched the 787 in December 2003. EIS was October 2011. Airbus’ A350, launched in response to the 787 in 2004, went through several iterations which added time to the program. Delays added more time. EIS was in January 2015.
Bombardier’s C Series was launched in 2008. EIS was in July 2016. The Boeing 777X was launched in 2013. EIS is now targeted for 2025. Boeing launched the 747-8 in 2005. EIS was in 2011. The Boeing 737 MAX was launched in July 2011. EIS was May 2017. Airbus’ A320neo was launched in December 2010. EIS was in January 2016.
Boeing has been discussing the New Midmarket Airplane (or whatever it was called throughout changing nomenclature) since 2012. It still hasn’t launched the program. Once it does, how long will it take to enter service?

Any new program is a multi-year, multi-million investment that, in the worst case, can take decades before recovering the initial development and production ramp-up expenditures.
Several recent programs, notably the 777X, have faced significant delays between the envisioned and actual start of deliveries to airlines.
Boeing claims that advances in manufacturing techniques will reduce the time required to develop the next aircraft program. However, regulatory scrutiny is higher nowadays and the aircraft built are more complex than in previous generations.
LNA analyzes how the time between the program launch and entry into service has evolved since the beginning of the Jet Age. The goal is to find whether there is a trend and in what direction. The analysis focuses on Airbus, Boeing, Lockheed, and McDonnell Douglas.
Summary
- An unmistakable trend;
- The latest clean sheet designs took significantly longer;
- Engine development dictates recent derivative program timelines;
- Future program considerations.
Pontifications: Why I’m cautiously optimistic about Boeing’s future
By Scott Hamilton
June 20, 2022, © Leeham News: Boeing still has a deep hole to climb out of. There’s still plenty of opportunity for missteps along the way. But I’m cautiously optimistic about Boeing’s future.
Here’s why.
- There are tangible things to point to that are indicators Boeing internally is now optimistic about its long flirtation with disaster.
- Despite well-deserved skepticism and concern about when, or even if, Boeing is going to launch a new airplane program, signs point to “yes.” These go beyond the usual rhetoric that often has a hollow public relations ring.
- The signs are there that Boeing at long last appears near resuming delivery of the 787, a critical step in its recovery.
- Clearing the inventory of the 737 has been infuriatingly slow. But if one had been paying close attention, this shouldn’t have been a surprise—and China’s refusal so far to authorize its airlines to return the MAX to service is but one issue.
Bjorn’s Corner: Sustainable Air Transport. Part 24. High Temperature Fuel Cells
By Bjorn Fehrm
June 17, 2022, ©. Leeham News: Last week, we looked at the installation effects and efficiencies of the fuel cell systems we discussed in earlier parts of the series.
We could see the variants were significantly heavier than the propulsion system they would replace for an ATR72 size aircraft. The discussion assumed classical PEM fuel cells, also called Low Temperature PEM Fuel Cells. Now we look at if High Temperature PEM Fuel Cells can improve the installation situation.

FAA adopts ICAO 2027 emissions, noise rules; death knell for new production 767F, 777F
- 787F, NMA-F are natural conclusions to consider for a successor to 767F
By Scott Hamilton
June 16, 2022, © Leeham News: The US Federal Aviation Administration yesterday announced it will adopt the emissions and noise rules proposed in 2017 to reduce emissions and noise in commercial jets and turboprops by 2027. Failure to comply means the offending airplanes can’t be produced from 2028. The rules won’t affect airplanes already produced.

The FAA’s move means that Boeing’s popular 767-300ERF and 777-200LRF can’t be produced from 2028.
The rules were adopted by the global organization ICAO, the International Civil Aviation Organization. But countries individually must adopt them. The FAA proposes a new rule to bring the US into compliance. By federal law, the FAA proposed rule must be published in the Federal Register. A comment period follows, after which the FAA either moves forward with the rule as proposed, revises it, or rejects its proposed rule based on the comments.
Boeing already announced a successor to the 777F: the 777-8F, a member of the 777X family. Entry-into-service is slated for mid-2027 before the rules take effect. Boeing doesn’t have a solution for the termination of the 767F production.

Introduction
June 16, 2022, © Leeham News: What is the best business; to transport cargo below the floor in passenger airliners or dedicated freighter aircraft?
The market clearly says both, as this is the state of affairs. Market economy says a business will find its optimal form, and it’s about fifty-fifty now. But what are the plus and minuses of these two very different ways of transporting cargo, and why do we have the present situation?
We search for answers by looking at the transport fundamentals and comparing costs with revenues.
Summary
- About half of the world’s cargo flies in the bellies of passenger aircraft, and the other half flies on dedicated freighters.
- What are the factors that have created this division, and will it change?
Migrating advanced processes from Defense to Commercial isn’t a cakewalk for Boeing

June 13, 2022, © Leeham News: Boeing’s CEOs, David Calhoun and his predecessors Dennis Muilenburg and Jim McNerney, said repeatedly the next Boeing airplane (NBA) will be as much as about production as it will be about the airplane. In fact, Calhoun says production is key to designing, producing, and delivering a less expensive airplane that will underpin the value proposition going forward.
Engine technology advances might achieve a 10% reduction over today’s CFM LEAP and Pratt & Whitney Geared TurboFan engines. So, advanced design and production is key to the business case for the NBA.
Despite using these advancements on Boeing defense programs (the T-7 Red Hawk trainer and MQ-25 unmanned aerial refueling airplane), assimilating them into commercial airplane development and production has high hurdles.
Summary
- Boeing has had mixed success using advanced technology design and production on its current commercial programs.
- Regulatory approvals will be challenging.
- Engines will be 10% better than the LEAP and GTF—but are these the correct comparisons?
Pontifications: Some customers anticipate up to year delay in certification of A321XLR
By Scott Hamilton
June 13, 2022, © Leeham News: Airbus scheduled the first flight of its Xtra Long Range A321XLR Wednesday.
Some customers think certification of the airplane will be delayed up to a year as Europe’s EASA and the USA’s Federal Aviation Administration demand changes to the integrated aft fuel tank that gives the XLR an advertised range of 4,700nm.
That was the consensus of those I talked to who gathered last week at an industry event in Chicago. Airbus already said the XLR certification will be delayed by a few months as regulators review how the fuel tank is integrated into the airplane.
Bjorn’s Corner: Sustainable Air Transport. Part 23. Fuel Cell-based 70 seat airliner
June 10, 2022, ©. Leeham News: Last week, we looked at the different fuel cell systems that can go into a 70-seat airliner like the ATR 72. In this week’s Corners, we implement these in the aircraft and look at installation effects and efficiencies.
The deeper discussion is in the sister article, Part 23P. Fuel Cell-based 70-seat airliner.
