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.

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.
Carbon footprint: Regional jet versus turboprop, how large is the difference?

Introduction
January 27, 2022, © Leeham News: Last week, we kicked off a series of articles where we will measure what difference our choice of flying makes to the primary Greenhouse gas emission, CO2.
We have upgraded our airliner performance model for the series to give a direct output of the CO2 emissions for the flights in different phases.
We start this week by comparing a typical domestic feeder flight of 300 nm, with an example route of Cleveland to Chicago O’Hare. What will be the time differences? And the fuel burn and CO2 emission difference?
To make it a fair comparison, we’ll use present generation aircraft flying on the US market, the Embraer E175 and De Havilland’s DH 8-400. We will fly the DH 8 at a high-speed cruise to keep the flight time differences within 10 minutes.

Summary
- As expected, the turboprop is the more efficient mode of transportation on the route. It consequently emits less CO2 per transported passenger.
- With new, more comfortable turboprops in the works, the drive for sustainability could see a return of the turboprop to the US market.
Forecast 2022: IRKUT

Introduction
January 24, 2022, © Leeham News: IRKUT became the Airliner company in Russia’s United Aircraft Corporation when the Superjet project was transferred from Sukhoi in February 2020.
The rationale was to focus the new single-aisle MC-21 and the regional Superjet in one entity where the needed investment in after-sales support, a chronic weakness of Russian aircraft, could be concentrated.
The MC-21 is the most advanced of the world’s single-aisle designs, with a roomy fuselage and a composite wing. But this, the market’s best design, has the worst chances for success. We go through why.
Summary
- The MC-21 has a fuselage design that makes it roomier without causing extra drag or weight.
- It also has the most advanced wing, an out-of-autoclave resin infusion design, the type which Airbus is aiming for in the “Wing of Tomorrow” project.
- But despite the best technology, it has the slimmest market chances. It has little to do with the aircraft itself.
Reducing one’s carbon footprint through flying choices

Introduction
Jan. 20, 2022, © Leeham News: Discussions about reducing commercial aviation’s carbon emissions have become more prominent over the last few years.
Many projects claim that electric(-hybrid) and hydrogen aircraft will be available in the not-too-distant future to make net-zero emissions flying a reality. Sustainable Aviation Fuels (SAFs) will also drastically reduce lifecycle carbon emissions with only minor changes to the current aircraft.
The IATA committed to a net-zero carbon emissions target by 2050. While all those long-term aspirations are well, significant challenges remain.
LNA has highlighted that the low energy density of batteries means that electric aircraft can at best work on small planes for short flights. Developing a medium-haul hydrogen-powered aircraft will require numerous innovations that suggest an entry into service before 2035 is not realistic. The challenges in increasing SAFs supply affordably to meaningful levels are monumental.
We have pointed out that all the above are far into the future. To meaningfully reduce emissions over the next decade, the introduction of more fuel-efficient gas turbines and turboprops is the only realistic and impactful lever.
Another lever has not been mentioned so far to reduce one’s carbon emissions. Other than not flying at all, how we fly from A to B can have significantly different carbon footprint levels.
This series will highlight the different levels of carbon emissions depending on how one flies on different routes.
Summary
- Setting the problem out;
- Challenges in defining unit emissions;
- Factors outside one’s control;
- Introducing a few examples.
2022 Forecast: C919 EIS unlikely before 2023-24

Introduction
Jan. 17, 2022, © Leeham News: COMAC, the Chinese aerospace company developing the C919, suffered yet another setback last year.
It hoped to deliver the first aircraft, designed to compete with the Airbus A320 and Boeing 737-800/8, to China Eastern Airlines by year end. Not only didn’t this delivery take place, but the program is also only about 15% through the certification flight testing.

At this rate, certification, and delivery this year is questionable. LNA’s forecast for EIS is in 2023 or 2024.
COMAC’s other airplane, the regional jet ARJ21, landed its first order outside China (other than from lessor GECAS years ago).
Summary
- C919 is overweight, shortening range, and adversely affecting fuel economy.
- Commercial success of the C919 won’t be possible.
- ARJ21 lands first foreign operator, but it’s not an arm’s length deal.
Air freight growth: one-hit wonder or long-term trend?

Introduction
January 13, 2022, © Leeham News: COVID-19 has upended the freight world, with air delivery now becoming relatively economical versus the high premium they previously commanded over sea freight. While air freight yields on most trade lanes are 2-3x their pre-pandemic levels, sea freight yields are 8-10x their 2019 levels in lanes like Asia to North America and Asia to Europe.
Sea freight schedule reliability has fallen sharply over the past 18 months driven by a spectrum of port, labor, and container availability issues. Shippers are increasingly frustrated by the large and growing number of “blank sailings,” the industry’s term for canceled departures.
To offer customers backup options – and increase their value capture – ocean freight carriers are starting to buy their own aircraft. Maersk announced its purchase of two Boeing 777Fs in November, while CMA CGM Group said in December that it would order four Airbus A350Fs to complement its existing fleet of five Airbus A330Fs.
As the COVID crisis extends into its third year, will air freight demand prove sustainable at today’s levels? To what extent will capacity increase to match?
Summary
- Sea freight capacity will remain tight for the foreseeable future.
- New-build freighter availability is limited at present.
- Today’s air freight demand spike is unlikely to last beyond mid-decade.

Introduction
January 10, 2022, © Leeham News: Embraer is the dominant regional jet aircraft supplier with a worldwide footprint and faces little competition to its products below 100 seats.
Between 100 to 150 seats, the situation is another after Bombardier “sold” its CSeries project to Airbus. Airbus’ might as aircraft OEM rekindled the CSeries as Airbus A220, and it’s now a vivid competitor to Embraer over 100 seats.
With a market it dominates and another where competition increases, we look at what’s in store for Embraer for 2022 as it hopes to exit the COVID pandemic for better times.

Summary
- Embraer is a complete supplier with capable development, production, and worldwide support for its regional jets.
- Everything would be good had Bombardier, a player the size of Embraer, slugged it out with CSeries. The hand-over of the modern aircraft to Airbus changed the competitive landscape.
