Introduction
Feb. 28th, 2022, © Leeham News: In recent weeks, we compared the 787-10 Heavy Gross Weight (HGW) performance against the A350-900. The 787-10 HGW will impact sales campaigns against the A350-900 and those of larger aircraft, the A350-1000 and 777X, and large freighters.
LNA now analyses the potential replacement market for very large aircraft (seating 350 or more passengers in standard configurations) and large factory-built freighters.

February 25, 2022, ©. Leeham News: This is a complementary article to Part 8. Serial Hybrid. It uses Leeham Company’s Aircraft Performance Model from our consultancy practice to analyze the design of a hybrid aircraft for short-haul commuter operations.
Our design brief is to make an aircraft that uses a minimum of carbon-based fuel by combining battery-based energy with energy from a generator driven by a gas turbine. Such a combination is called a Serial Hybrid.

February 24, 2022, © Leeham News: The CEO of Boeing Commercial Aircraft (BCA), Stan Deal, said at the Singapore Air show the company worked on increased gross weight versions of both the 787-9 and -10.
Target is to get the 787-10 to the range of the aircraft it shall replace, the 777-200ER and -300ER. It means more than 7,000nm of range against the 6,400nm of today.
How many tonnes of increased Gross weight does this mean, and what would be the performance compared with the Airbus A350-900? We use our airliner performance model to find out.

February 16, 2022, © Leeham News: Last week, we looked at the operating economics of the Boeing 777-8F and Airbus A350F. Both freighters are new launches over the last 6 months with planned service entry 2025 (A350F) and 2027 (777-8F).
We flew the freighters with the help of our Aircraft Performance Model over a typical freight trunk route from Shanghai to Anchorage at a full load and compared their economics with the present freighter in this class, the Boeing 777F. Readers demanded we fly them with a part load and on shorter routes, so here we go.

Introduction
Feb. 14th, 2022, © Leeham News: Boeing Commercial Aircraft (BCA) CEO Stan Deal announced that the company was working on a high gross weight (HGW) variant of the 787-10 Dreamliner.
LNA later revealed that the maximum takeoff weight (MTOW) increase would also be available on the 787-9. The goal of the increased MTOW is to make the 787-10 more competitive against the A350-900, which currently has a significantly higher nominal range: 6,430 nm vs. 8,100 nm. The 787-10 HGW range should match that of the 777-200ER.
The 787-10 HGW targets replacing larger, older-generation, twin-aisle aircraft still in service, notably the 777-200ER and 777-300ER. Boeing’s primary goal is to prevent customers from ordering the Airbus A350-900 due to a lack of payload-range for the 787-10.
Boeing paused developing the 777-8 around 2.5 years ago, and it is not clear whether the variant will ever enter service. Therefore, without the 787-10 HGW, there would be a sizable seat gap between the 787-9 (290) and 777-9 (414) in the American OEM’s long-range twin-aisle offering. Both A350 variants are in that seat gap.
The arrival on the market of the 787-10 HGW has the potential to affect sales opportunities for the A350 and the 777X. LNA analyses the potential replacement market for long-range aircraft seating 300 or more passengers in this context.

February 11, 2022, ©. Leeham News: This is a complementary article to Part 6. Energy consumption. It uses the Aircraft Performance Model from our Consultancy practice to generate energy consumed data when we fly a typical airline mission for the first aircraft we analyze, the battery-based Eviation Alice and Heart Aerospace ES-19.
These represent what to expect for airliners that have chosen this energy storage principle.

February 10, 2022, © Leeham News: Boeing introduced the freighter version of the 777X last week, and we made a first article about how it stacks up against Airbus’ new freighter, the A350F. The Boeing freighter will be the market’s largest freighter when it enters the market in 2027, two years after the A350F.
We now use our performance model to fly the new freighters against the present Boeing 777 freighter, the 777F, to look at their operating economics.

February 7, 2022, © Leeham News: The year that passed was when Sustainability broke through the walls of “I’m not convinced we have a problem” and “If so, what shall we do about it.”
The declarations ahead of, at, and after COP26 in Glasgow, United Nations 26’th climate conference, had many major states and organizations commit to targets for the reduction of Greenhouse gases by 2030 and 2050.
With this change in mind and traction, what can we expect to see in 2022 from the Air Transport industry?

February 3, 2022, © Leeham News: Boeing launched the new large freighter, 777-8F, Monday with an order for 34 and options for 16 from Qatar Airways.
We made a comparison based on projected data in August 2021 of the 777-XF versus an A350 freighter, but now we have final data for both. We can now compare the 777-8F from Boeing with the A350F from Airbus. We also compare these with the present Boeing freighter, 777F.
The new freighters represent the largest freighters that will be in the market at the end of the decade, as Boeing’s 747-8F ends its production after the summer. The A350F starts deliveries during 2025, and the 777-8F joins in 2027.
We start with comparing freight capabilities, and then we fly them on a typical freight route, using our aircraft performance model.
