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.
Could an NMA be made good enough, Part 4?

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.
Delta reviewing Airbus wide-body order, but more is going on
Subscription Required
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.

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.
Middle Eastern airline turmoil hits Boeing

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?

Things get worse before better at Cathay
April 6, 2017, © Leeham Co.: Cathay Pacific Airways faces a loss this year after posting its first loss in eight years last year.
Analysts following the Hong Kong-based airline see another loss, with declining revenues and pricing pressure from competition.
Could an NMA be made good enough, Part 3?

Introduction
April 6, 2017, © Leeham Co.: After sizing the cabin of the NMA, the time has now come to size the fuselage. Can a fuselage be designed that gives an NMA “dual aisle comfort with single aisle economics”?
Figure 1. The NMA takes more and more the shape of a 767 replacement (A United 767-200). Source: United
We will investigate the dimensions, the drag and the weight of an NMA fuselage. It will be based on the cabin and design techniques we described in Part 2. We then compare the efficiency of the result with the fuselages of the Airbus A321LR and Boeing 767. This will show if the necessary efficiency can be achieved.
Summary:
- It’s possible to design a dual aisle fuselage with the same perimeter per seat abreast as a single aisle fuselage.
- This will make the central, cylindrical, section have competitive weight and drag characteristics.
- The larger diameter of the dual aisle fuselage will increase the size of the tapered front and rear sections however.
- It’s still possible for an NMA fuselage to be as weight-efficient as a single aisle fuselage, measured per transported passenger.
Pegasus Airlines, bridging Europe and Asia
By Bjorn Fehrm
April 05, 2017, ©. Leeham Co: Turkey’s Pegasus Airlines has its operations center south of Hungary’s Wizz Air that we wrote about last week. With a hub in Istanbul, the Turkish LCC connects Europe and West Asia/Middle East.
Pegasus is a fraction larger than Wizz Air and had the same dynamic development until last year, when the internal unrest in Turkey threw a spanner in the airline’s growth. Read more
