Pontifications: Engines drive timing of new Embraer TPNG
The first report appeared Oct. 18, 2021.
By Scott Hamilton
Oct. 25, 2021, © Leeham News: Embraer appears marching toward launching a new turboprop aircraft next year with a targeted 2027 entry into service.
The timing will be determined by the engine. Pratt & Whitney, GE Aviation and Rolls-Royce have development programs. PW and GE are farthest along. PW is thought to have the best chance of winning Embraer’s business. (Pratt & Whitney supplies the engines for the E2 jet. GE supplied the engines for the E1.)
In an interview at the IATA AGM Oct. 3-5 in Boston, Arjan Meijer, the president of Embraer Commercial Aviation, said the competition remains open today.
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
August 5, 2021, © Leeham News: Two weeks ago we compared the launched Airbus A350 freighter with Boeing’s in-service 777F. We found the 777F is a freighter with a very high payload capability, but it faces an ICAO emission and noise ax by 2028, should the present engines be kept.
Boeing’s CEO David Calhoun recently said a freighter version of the 777X might replace the 777F. With seven years to 2028, a development decision for a 777-XF is then imminent. We use our performance model to look at how an A350F and 777-XF would compare.
Summary
- A new Boeing 777-XF freighter, based on the 777-8 (picture), has to equal or beat an Airbus A350 freighter both on payload and economics.
- Beating an A350F on capacity and payload is straightforward, the 777-8 is the larger aircraft. On operating costs, it’s a tighter race.
De-carbonisation of air transport is ON
By Bjorn Fehrm
July 20, 2021, © Leeham News: Last week was a game-changing week for air transport. Three events synchronized to trigger it.
EU presented 13 policies to achieve net-zero greenhouse gas emissions by 2050 with concrete steps in-between. On the same day, the airframe and engine OEM’s CTOs said in a Farnborough Connect webcast: “It’s a commitment problem, not a technical problem to achieve the EU goals.”
This happened against a backdrop of European floodings, which made all discussions about climate change or not moot. Super-organized Germany lost over 100 persons to typhoon like rains, never seen before, that produced scenes like these: https://twitter.com/Aviation_Intel/status/1416215953080205321?s=20

CFM announces the RISE engine program
June 14, 2021, © Leeham News: GE and SAFRAN took to the stage today to announce the extension of their CFM joint venture to 2050 and the CFM technology program RISE.
RISE stands for Revolutionary Innovation for Sustainable Engines, and it elevates previous work to new levels and introduces some news.

Pontifications: AerCap and GECAS to combine — assessing the impact
By Scott Hamilton
March 15, 2021, © Leeham News: GE Corp.’s decision to sell its mega-leasing unit, GECAS, to AerCap represents a huge shift in commercial aviation.
For decades, GECAS was the largest lessor in the world. One of GE’s best profit centers, GECAS was a major source of financing to airlines. The lessor purchases and leases back airliners, as do most lessors, as well as initiating leases with orders received directly from the OEMs. GECAS’ scale was a magnitude or two larger than most competitors.
The closest competitor was International Lease Finance Corp., a unit of insurance giant AIG. ILFC’s leadership liked to boast the asset value of ILFC’s smaller fleet was greater than GECAS, which while larger had more older airplanes in its portfolio.

Introduction
March 11, 2021, © Leeham News: Last week, we started analyzing the Airbus A350-1000 and compared it with the Boeing 777-300ER.
We now fly the airplanes on a demanding route, close to their maximum range, the LAX to Hong Kong sector. How much better is the 14 years younger A350-1000?
Summary
- The A350-1000 is the logical replacement for a 777-300ER if a same capacity replacement is sought.
- The carbon-fiber structure, a more advanced wing, and newer engines give the A350-1000 convincing arguments for the change.

Introduction
February 11, 2021, © Leeham News: Last week, we started analyzing the main member of the Airbus A350 family, the A350-900. It’s the design center for the A350 family and has so far 747 orders, of which 354 are delivered.
Over 1,000 Boeing 777 airliners in the market need replacement, and the A350-900 targets about half of these, the 777-200 and -200ER. Delta is one airline that started the switch from 777-200ER to A350-900. How much does Delta stand to gain?
Summary
- The 777-200ER broke the ground for oceanic twin-engine flights. It offered an improved economy on trans-oceanic routes.
- Airliner technology advanced for the 18 years younger A350-900, spurred on by Boeing’s technical leaps with the 787 Dreamliner.
- As the A350-900 employed these gains in the 777-200ER size class, it does to the 777-200ER what it did to Airbus A340-300, it wins the economy race hands down. Read more

By Bjorn Fehrm
Introduction
January 28, 2020, © Leeham News: Last week, we analyzed the smallest member of the Airbus A350 family, the A350-800. After Airbus changed the variant to a non-optimal “cut and shut” variant, it was no longer competitive.
Airbus froze the development of the A350-800 and then let it slip out of the program (it’s never officially canceled). The A330neo became the replacement for the A350-800. Was this the right decision? Is the A330neo the better airplane?
Summary
- We saw the A350-800 in its final form had a problem competing with Boeing’s 787. This created a problem for the Airbus widebody program below 300 seats.
- After a thorough investigation, Airbus found a way to update the A330 to take the place of the A350-800. We use our airliner performance model to find out how well the replacement performs.

Introduction
January 21, 2020, © Leeham News: Before the holidays, we started a series to look into Airbus’ A350 family. We analyzed the development program and how the variants have sold.
Initially, the A350-800 won about 180 orders. But as the market received more information about the smaller variant, the more it realized it wasn’t an optimal airplane. It was never officially canceled. But orders was up-gauged to the A350-900. Airbus decided the variant wasn’t competitive and developed the A330neo instead. We now look into why.
Summary
- The A350-800 was positioned as Airbus’ main defense against Boeing’s new 787-9, the most efficient variant of the Dreamliner.
- As the A350 program was delayed, the A350-800 moved from an optimized variant to a “cut and shut” version. This compromised its efficiency.
- Gradually Airbus changed its strategy how to compete with the 787.
