Introduction
Oct. 24, 2022, © Leeham News: Last month, Airbus announced that it started delivering A350s with a New Production Standard (NPS) with Iberia. The upgrades include weight savings, a maximum takeoff weight increase, and a longer and wider cabin.

Except for a few low-cost operators, the economy-class cabin on the A350 has usually featured a nine-abreast configuration with operators. The wider cabin could lead to a wider adoption of a 10-abreast economy class configuration with more A350 operators, for instance the legacy ones.
Despite the lingering effects of the Covid-19 pandemic on long-haul travel, several airlines still need to place sizeable twin-aisle aircraft orders in the coming years. The A350 enhancements could prove crucial in securing orders for Airbus against the competing Boeing 787 and 777X.
In this article series, we will assess how the A350 enhancements impact the economic performance of the aircraft against its main competitors. Before comparing competing aircraft, we define a methodology for consistent comfort standards among different aircraft families.

- A brief history of adding economy class seats in each row;
- Assessing passenger comfort standards;
- Upcoming twin-aisle sales campaigns.
Lockheed Martin expects competitive bidding for next tanker
By Byan Corliss
Oct. 25, 2022 © Leeham News: A Lockheed Martin official said the company believes the U.S. Air Force will end up seeking competing bids for the next batch of aerial refueling tankers it will buy.
When that happens, the company is confident the Air Force will pick its proposed LMXT tanker, based on the Airbus A330 airframe, for the role, said Larry Gallogly, who is Lockheed Martin’s director for the tanker campaign.
Back in 2007, the Air Force outlined a plan under which it would replace its then-existing tanker fleet in three rounds, KC-X, KC-Y and KC-Z.
KC-X, after many missteps, became the KC-46 program. The Air Force now is looking ahead to KC-Y, but with the recent steps forward with Boeing’s KC-46, some are arguing that a full-blown tanker competition isn’t necessary because USAF could just tack on additional orders to the 179 KC-46s it now plans to buy.
But during a briefing from Lockheed Martin’s offices in Alexandria, Va. today, Gallogly said he expects the Air Force will announce its criteria for the next round of tankers after the first of the year. When it does, Gallogly continued, it’s likely that the Air Force will be seeking a more-capable tanker than the one it’s buying now.
“If we take all of the stakeholders at their word that the requirements are vastly different than they were 16 years ago, that takes you down a path where a competition is more likely than not,” Gallogly said.
Summary
- Lockheed Martin teams with Airbus for proposal
- LMXT differnt from Airbus KC-330
- USAF approved KC-46 for all missions last month
HOTR: Amazon to add A330 P2F to Prime Air fleet
Oct. 21, 2022, © Leeham News: Amazon’s Prime Air will add 10 Airbus A330-300 freighters to its fleet from 2023. The aircraft will be converted by EFW, in which Airbus is a partner, and leased from Altavair of Issaquah (WA).
Source: Airbus.
These are the first A330 freighters that will be operated under the Prime Air brand. Hawaiian Airlines, an A330 operator, will operate the planes. Prime Air largely contracts out flight operations. Atlas Air flies Boeing 767-300ERFs and Sun Country fly Boeing 737Fs for Prime Air.
EFW now has orders for more than 100 A330 conversions, nearly all for the -300 model.
Pontifications: Energy costs add to aerospace supply chain squeeze
By Scott Hamilton
Oct. 17, 2022, © Leeham News: The aerospace supply chain faces new strains due to rising energy costs, Airbus CEO Guillaume Faury said last week.
Bloomberg News reports that Faury said some suppliers are shutting down due to high costs.
“We see another thing coming, which is the consequences of energy prices skyrocketing leading to some suppliers trying to adapt, sometimes stop producing, waiting for the situation to normalize,” he said. “That’s very low in the supply chain, but it’s probably something new,” Bloomberg wrote. It was reporting on Faury’s appearance before the UK Aviation Club.
At an unrelated event last month, two top US suppliers said they continue to see financial distress in the supply chain. Some lower-tier suppliers had filed for bankruptcy and more may be expected.
Analysts forecast traffic growth but scant profits for Indian airlines

Oct. 17, 2022 © Leeham News: After sustaining major losses in their most-recent fiscal years, India’s airlines will recover in 2022. But rising fuel and labor costs, plus weak prospects for financing will constrain near-term growth.
That’s the analysis of Aairavat Transport & Technology Ventures consulting firm.

AT-TV’s assessment is less bullish than Boeing’s market outlook, which projects Indian airlines to add 25% capacity over the next year, with long-term growth targeted for 7%. Airbus is slightly more cautious, projecting 6.2% annual growth over the next two decades.
India is one of the world’s largest aviation markets. It’s also been one of the most challenging, with bankruptcies and constant financial distress plaguing the industry.
Summary
- India airlines have been in upheaval
- Tata Group wants new aircraft for Air India
- Indian airlines sustained major losses last year
- OEMs see long-term growth, but near-term outlook is choppy
Engine Development. Part 9. Gearbox or not?

By Bjorn Fehrm
Introduction
October 13, 2022, © Leeham News: In our series, we look at the development of the latest single-aisle engines. Should these be geared? What do you gain and risk with a geared design? Is this a new development, or has it been around for a long time?
We examine the development of single-aisle engines since 2000, their fuel efficiency, and operational reliability.
Summary
- A geared design fixes some fundamental problems in a two-shaft turbofan.
- CFM proves you could just as well further develop what you have.
Engine Development. Part 8. Throttle push or not?

By Bjorn Fehrm
Introduction
October 6, 2022, © Leeham News: The early years of 2000 saw new engine programs launched for the new Boeing 787 Dreamliner and Airbus response, the A350.
Substantial differences in the life of these aircraft programs made the engine programs develop differently. It was about throttle push or not.
Summary
- The Dreamliner engines changed as the 787 programs went through many stages.
- The Airbus A350 program was a standard program in comparison.
Engine Development. Part 7. Engine reliability changes the aircraft market

Introduction
September 29, 2022, © Leeham News: The 1970s saw the introduction of the High Bypass engine for the medium/long range Boeing 747, Douglas DC-10, and Lockheed Tristar, with Airbus A300 employing an updated variant of the DC-10 engine for medium range missions.
In the following decades, these engines introduced improved technology and matured into new levels of reliability. With the increase in reliability came changes in how long-range aircraft were designed.

Summary
- The engine development after the introduction of the high bypass turbofans in the 1970s focused on reliability and higher efficiency rather than new design principles.
- The change in reliability made the two-engined long-range aircraft the winner over three and four-engine aircraft.
Pontifications: Single-pilot jetliners OK for cargo, not yet for passenger airplanes
By Scott Hamilton
Sept. 26, 2022, © Leeham News: I sat down with Fred Smith, the founder and now executive chairman of FedEx, on Sept. 15 at the US Chamber of Commerce Aerospace Summit. The first article appears here.
The balance of the interview covered a wide range of topics. I’ll summarize them below.
Engine Development. Part 6. High Bypass goes mainstream

Introduction
September 22, 2022, © Leeham News: With the introduction of the High Bypass engine for the Boeing 747, Douglas DC-10, and Lockheed Tristar, it was obvious Pratt & Whitney’s low bypass engines on the Boeing 707, 727, 737, and Douglas DC-8, -9 should be attacked with a new High Bypass engine in this thrust class.
French Snecma and GE teamed up to break Pratt & Whitney’s monopoly of the jet engine market outside the widebodies. The CFM56 was born.

Summary
- With an exclusive fit on the Boeing 737 and a 10-year introduction advantage on the A320, the CFM56 has dominated over the competing IAE V2500.
- The CFM56 is the world’s most produced jet engine, with over 32,000 engines produced to date.
