Bjorn’s Corner: Aircraft engines in operation, Part 4
By Bjorn Fehrm
February 10, 2017, ©. Leeham Co: We now continue our journey how an airline engine is operated during a typical mission.
Last week we explained basics for engine control and Take-Off flat-rating. We now continue with Climb, Cruise and Max Continuous ratings and why these are important.

We also touch on de-rating and Cost Index and how these affect how the engine runs.
Norwegian, from regional to mainline competitor
By Bjorn Fehrm
Introduction
February 8, 2017, ©. Leeham Co: When SAS (Scandinavian Airlines Systems) canceled Norwegian Air Shuttle’s (NAS) contract to feed its Norwegian network 2002, it had no idea the former feeder would almost run it out of business 10 years later.
The cancellation forced NAS to change tack. Subcontracting as a feeder to a mainline was no longer possible; SAS was the only mainline in Norway after buying Braathens (NAS’ original contractor). NAS decided to become a Low Cost Carrier (LCC).
Ten years later, Norwegian (as we call NAS from now) had taken over a large part of SAS’ European business. SAS was fighting for its life. Another five years and Norwegian’s expansion on LCC long-haul is forcing IAG (BA, IBERIA, Air Lingus, Vueling), Air France-KLM and Lufthansa to react.
How strong a threat to other LCCs and the majors’ long haul operation is Norwegian? We will answer the questions in a series of future articles. We start with Norwegian’s roots and its development til now. Read more
Assessing the future of COMAC programs

Introduction
Feb. 6, 2017, © Leeham Co.: China’s effort to become a viable commercial aerospace alternative was filled with rocky fits and starts for its two signature airliner programs, the AVIC ARJ-21 and the COMAC C919.
COMAC, a spin off from AVIC and yet another government-controlled entity, is already casting eyes on a 250-seat, twin-aisle design, the C929—ostensibly in a joint venture with Russia’s United Aircraft Corp.
The ARJ-21 regional jet finally entered service after delays of eight years. The C919 target EIS is now 2019, six years after the original date. The first flight hasn’t even taken place.
Chinese officials set a target EIS for the C929 of 2026.
A rough road remains ahead for each program.
Summary
- Exceedingly slow delivery ramp up for the ARJ-21.
- First flight of the C919 planned this year.
- Wide-body C929 will challenge the Airbus A330 and Boeing 787.
United: the road back
By Bjorn Fehrm
Introduction
February 1, 2017, ©. Leeham Co: A headline from one year ago read: “UNITED’S QUEST TO BE LESS AWFUL: A bungled merger. A corruption scandal. Three CEOs in a year. But hey, at least the snacks are free again.” (Bloomberg 14 January 2016).
“Things have changed, but not everything is fixed yet,” said Gary Laderman, United’s SVP Finance, Procurement and Treasurer, at the Airline Economics Growth Frontiers conference in Dublin last week.

Laderman then candidly went through the history, the fixes and why there is more to come. Read more
Pontifications: No rate increase on Boeing 787 predicted
Jan. 30, 2017, © Leeham Co.: Boeing will decide this year whether to boost 787 production to 14/mo from 12/mo by the end of the decade.
I don’t see how this can happen. Neither do several aerospace analysts.
Book:bill sales were just 0.36 in 2014, 0.53 in 2015 and 0.42 in 2016. The last three years saw a book:bill rate average of just 0.43, or an average of 57 airplanes per year.
Boeing is burning off the backlog, not adding to it. At this rate, Boeing won’t be able to sustain rate 12 beyond 2020, let alone boost the rate in 2019.
Not unless there is a plethora of sales this year. This doesn’t seem likely.
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
