Bjorn’s Corner: Aircraft engines in operation, Part 2
By Bjorn Fehrm
January 27, 2017, ©. Leeham Co: In the last Corner, we began looking at the in-service operation of a Turbofan. We covered how thrust and fuel consumption varies in the different phases of an airliner’s mission.
Now we will dig a little deeper into how a mission will stress the engine’s different parts.

With this knowledge, we will later look at how operators make sure their engines are safe and in good operational condition over the 20 years life of an aircraft. Read more
Assessing A330, A350 production futures

Introduction
Jan. 26, 2017, © Leeham Co.: Airbus A350 production rates are solid at 10/mo through 2022 but can’t support increasing them to the oft-discussed 13/mo, based on LNC’s analysis of the current backlog.

The backlog currently falls off sharply in 2023. At six years out, there is plenty of time to fill the production gap—in theory. The dearth of wide-body orders through the end of the decade could make this challenging.
The A330 is a near-term challenge.
According to an analysis of its backlog, only three-quarters of the delivery slots are filled in 2019 and fewer in 2020. The backlog begins to fall sharply in 2021.
Summary
- A350, like Boeing 787, is not achieving 1:1 book:bill.
- Like the 787, the A350 production is currently living off the backlog.
- A330neo sales are focus at Airbus this year. Delivery schedule falls off in 2019.
A380, from flagship to LCC mass transport
By Bjorn Fehrm
January 23, 2017, ©. Leeham Co: The Airbus A380 was introduced as the flagship aircraft for an airline’s fleet. Legacy carriers with a large long-haul network introduced the aircraft on the routes with the most traffic in the network. After an initial rush of inductions, only Emirates continued to buy the aircraft in larger numbers. The aircraft had become too large for the airlines which sought frequency over capacity at their hub airports.
Airbus and its leasing partner, Amedeo, are convinced the aircraft will have a second spring when airport congestion has grown in the next decade. Until then, both are seeking the market niches that will keep production at minimum one aircraft per month.
We sat with Amedeo’s CEO, Mark Lapidus, at the Air Finance Journal conference in Dublin to find out what market will require a new or used A380. Lapidus has spent the last two years in meetings with the world’s major airlines, discussing all aspects of operating an A380. He presented some surprises.
Pontifications: Airbus, Boeing single-aisle production rates solid
By Scott Hamilton
Jan. 23, 2017, © Leeham Co.: The global economy is softening and airlines are deferring airplanes, but we don’t see Airbus or Boeing trimming aircraft production for their single-aisle airplanes.
Over-sales and rising fuel prices support today’s A320 and 737 production rates and the increased rates previously announced by Airbus and Boeing.
While oil prices are low compared with the pre-Great Recession levels, Embraer’s John Slattery noted that fuel costs went up more than 48% last year alone. Fuel now costs more than $50/bbl. West Texas Intermediate Crude was selling at $51.08 Thursday, off $1.40. There will be ups and downs, but the trend is up.
Slattery, the president of Embraer Commercial airplanes, believes “fuel efficient fleets will become more critical in the coming years,” he wrote in a Tweet Jan. 7.
A380 cost analysis

Introduction
Jan. 23, 2017, © Leeham Co.: In a sister article, we will describe how Airbus A380 might change from a flagship aircraft for legacy carriers to a competitive tool for long-range LCCs.
This change of the A380’s profile is based on bringing cabin densities to the levels of other long haul aircraft. We have historically made detailed operating costs studies of the A380 versus other large long-haul aircraft.
With the possible change in the aircraft’s operating profile, we decided to update the study with the A380ceo pitted against its main competitors, Boeing’s 777-300ER and 777-9. Different from the previous study, we now compared all aircraft in a higher density, two-class seating.
Summary:
- The A380neo is pushed out in time for now. Airbus has instead started a cabin density program.
- We update the study of A380 versus its main competitors to see if the cabin changes goes far enough.
- In the last study, the A380 had lower seat mile cost than 777-300ER but was beaten by the 777-9.
- We check if a denser cabin makes the A380 competitive with the 777-9
Filling the Middle Of the Market gap
By Bjorn Fehrm
January 17, 2017, ©. Leeham Co: Airbus and Boeing had completely different views about the product strategy for the “Middle of the Market” sector (MOM), both for today and the future.
Officials presented their views on how to fill the “Middle of the Market gap” at the Air Finance Journal conference in Dublin.
The Airbus view is: “We got it all covered”.
Boeing’s view is: “Not so fast, there is more to it than meets the eye.” Read more
The aircraft market will double in 20 years
By Bjorn Fehrm
January 17, 2017, ©. Leeham Co: The market for passenger aircraft will double over the next 20 years, says Angus Kelly, the CEO of the world’s largest aircraft lessor, AERCAP. He forecast this growth, which is in sync with those from Airbus and Boeing, in his keynote speech at the Airline Economics Growth Frontiers 2017 conference in Dublin.
Kelly linked the growth with the increase in Global air travel. He started by showing what happened in the air travel industry during 2016, Figure 1.

Passenger travel grew with 5.6% and airlines were more profitable. Negative news was a slowing GDP in China and a widebody market that had a continued slowdown.

Pontifications: Planes nobody wants
By Scott Hamilton
Jan. 16, 2017, © Leeham Co.: Airbus and Boeing continue to offer planes that nobody wants.
Well, almost nobody.
The aircraft remain on the published price lists of both companies, for reasons that passeth understanding. Nobody ordered the aircraft for years.
Boeing 737 MAX 10

By Bjorn Fehrm
Introduction
January 17, 2017, © Leeham Co.: Boeing has given its sales team the “authority to offer” the 737 MAX 10. The aircraft is a stretched version of the 737 MAX 9, designed to compete more successfully with Airbus A321neo.
Boeing worked on the variant for the last year. It started off as a more ambitious change over the 737 MAX 9, but it turned out too expensive and would have taken too long to get to market. The variant that Boeing now offers to airlines is a simple stretch of the 737 MAX 9.
The backing down to a stretched MAX 9 solves the cost and timing problem, but will it solve the competitiveness problem? We make a first analysis.
Summary:
- The offered 737 MAX 10 is a longer fuselage MAX 9.
- The longer fuselage closes the cabin dimensions gap to the A321neo.
- The 737 MAX 10 is longer and heavier than the MAX 9, affecting performance.
- To save field performance, a change to the main landing gear was necessary.
Bjorn’s Corner: Geared turbofans
By Bjorn Fehrm
January 13, 2017, ©. Leeham Co: The time has come to go through the reasons why some turbofan engines are designed with a gearbox between the fan and the low pressure shaft.
The principle design is shown in Figure 1. It’s a graphical representation of a geared turbofan from the engine analysis software GasTurb.

The base idea is to have the low pressure spool of the engine to run at a considerably higher RPM than the fan. Read more
