Bjorn’s Corner: Aircraft engines, sum up
By Bjorn Fehrm
April 14, 2017, ©. Leeham Co: We’ve been talking engines on Fridays since October 2016. The Corners covered several areas, from technologies to operations.
And we could go on and dig deeper. But we will move on.
Before we go, we sum up what we have learned in the 24 Corners around airliner Turbofans.

two people to long-standing vacancies to allow ExIm to approve deals more than $10m.
ExIm, Trump now says, is a profit center for the US Treasurer.
His sudden understanding on this revelation is like his eye-opening realization that dealing with the North Korean situation isn’t easy.
Supporters of ExIm pointed out for years that the Bank returns money to the US Treasury.

Introduction
April 13, 2017, © Leeham Co.: Last week we finished the sizing of the fuselage for an NMA design. Now we continue with the wing. We go through the key parameters that will decide the performance of the wing and the aircraft.
The NMA is a critical design case. The performance envelope has to be just right. Too high and the economics of the aircraft won’t work, both for purchase price and operational costs.

Summary:
- Wing design is the mixing of conflicting requirements to a successful compromise.
- The NMA wing will use the design principles of the Boeing 787/777X wings but will be different in area, size and plan-form.
- The wing is sizing the engines, something we will look at in the next article.

Introduction
April 12, 2017, © Leeham Co.: Delta Air Lines today said on its earnings call that it is reviewing its wide-body order with Airbus.
At face value, the Delta statement might seem alarming. But as so often becomes the case, the “review” may not be what it seems.
Summary
- There is more activity about fleet requirements than simply “reviewing” the wide-body orders.
- Delta’s preparing to issue an RFP for single-aisle Airbus A321neos and/or Boeing 737-9/10s.
- Boeing hopes Delta will be a launch customer for the MAX 10.
- The NMA/MOM aircraft could be involved.
Aeroflot, the route to a modern airline
By Bjorn Fehrm
April 12, 2017, ©. Leeham Co: Aeroflot, established as the Soviet Union’s flag carrier in 1923, transformed from a state enterprise to a modern airline group after the fall of the Soviet Union in 1991.
The airline is today Europe’s seventh largest airline, two-thirds the size of Turkish Airlines, but having the same fast growth since 2005. We will cover Aeroflot’s journey in a series of articles, starting with the group’s history.

United’s new advertisement after passenger incident
April 11, 2017: United Airlines is in the midst of a public relations nightmare following Sunday night’s incident in which a passenger was dragged off a flight at Chicago O’Hare International Airport.
A new commercial was immediately launched, debuting on the Jimmy Kimmel show. Kimmel had his own caustic remarks.
United also recognized that it needed a new training procedure following the incident. The following is a video for its customer service training.
Pontifications: 787 production rate remains a question
By Scott Hamilton
April 10, 2017, © Leeham Co.: Boeing’s first quarter earnings call is scheduled for April 26, two weeks and two days from today. Officials said on the January earnings call, for year-end 2016, that they will decide this year whether to increase the 787 production rate to 14/mo by the end of the decade.
LNC has long believed this won’t happen. In fact, we predicted last September Boeing will have to lower the production rate from 2020.
The question of the rate is sure to come up on the 26th. I doubt CEO Dennis Muilenburg will be prepared to announce a decision one way or the other. It’s Boeing’s pattern to put off announcements like this until the very last minute, so a go-no go on rate 14 probably won’t be announced until toward the end of the year.

Introduction
April 10, 2017, © Leeham Co.: Tim Clark of Emirates Airline said the new breed of long-haul, low cost carriers are hurting EK’s load factors and yields.
Etihad Airlines’ business strategy of taking financial stakes in LCCs hasn’t produced the positive financial results desired.
Three big airlines, EK, EY and Qatar Airways, face over-capacity now compounded by electronic carry-on restrictions by the US and UK.
Figure 1. Click on image for a crisp view.
The thee carriers largely compete for the same connecting traffic through hubs only 72-235 miles apart (Figure 1). This is like having hubs in Milwaukee and Chicago (81 air miles apart) and Chicago-Detroit (237 air miles) with much, much smaller domestic catchment basins.
Summary
- Declining financial results for Emirates, Etihad.
- Deferring airplanes: 787s, 777X
- Long-haul LLC, Trump travel ban, poor investments hurt the airlines.
Bjorn’s Corner: Aircraft engine maintenance, Part 6
By Bjorn Fehrm
April 7, 2017, ©. Leeham Co: Last week’s Corner developed the overhaul shop visits per year for wide-body engines. We will now look at how the market develops around these overhaul opportunities.
How does the shop structure develop over a popular engine’s life-cycle? How much choice has an operator and when?
