Dec. 5, 2016, © Leeham Co. Last weeks’ approval by the US Department of Transportation of a license for Norwegian Air Shuttle to operate long-haul, low-cost service to and from the US drew immediate fire from labor unions over anticipated US job losses.
But their view is too narrow.
It means more jobs for Boeing and its supply chain, which are also heavily unionized. It means benefits to US exports.
But overlooked is the next evolution in long haul travel that starts next year.
Dec. 5, 2016, © Leeham Co.: Far be it from me to say, I told you so.
But I did.
When Washington State extended the Boeing 787 tax breaks in November 2013 to the 777X through 2040, I wrote and told everyone who would listen (and even those who wouldn’t) that the 787 tax breaks had been found illegal. So extending them was extending illegal tax breaks.

December 02, 2016, ©. Leeham Co: We will now look at the combustor area in our series on modern turbofan engines. There is a lot of activity in this area, as it sets the level of pollution for the air transportation industry for some important combustion products.
We will also finish off the compressor part of our series by looking at the bleeding of cooling air for the engine and for servicing the aircraft with air conditioning and deicing air.
The amount of air which is tapped from compressor stages for cooling and other purposes can exceed 20% of the core flow (some of the flow paths are shown in Figure 1). At that level, it has a marked influence on the performance of the engine. Read more

December 01, 2016, ©. Leeham Co: Boom Technology and Virgin Atlantic plan to offer supersonic business class passenger traffic over the Atlantic. We covered the number of challenges that this poses in recent articles. The most difficult challenge is finding a suitable engine.
We started the investigation into a suitable engine in the last article. A Supersonic Transport Aircraft (SST) needs an engine which is very different from the latest crop of high-performance airliner engines.
The air entering the engine intake at Mach 2.2 is taken from standing still to a speed of 450m/s within a fraction of a meter. This raises the air pressure and temperature more than the combined intake/fan/low compressor does for a modern turbofan. The result is that the core’s high pressure compressor must adapt; it can’t have a high compression ratio (then things get too hot).
Add to that, that the engine must be slender. It can’t have a wide fan and therefore high by-pass ratio because the supersonic drag of such large engines would be too high.
Nov. 29, 2016, (c) Leeham Co.: When it comes to the prospect of imposing trade sanctions or retaliatory tariffs on Airbus for airplanes ordered by US customers, the European manufacturer has some advantages over Boeing few people apparently have thought about.
One is called Alabama. It’s where Airbus is producing A320 family members for US customers.
Alabamans voted by 1.76-to-1 for Donald Trump. Sixty-three percent to 35%.
Donald Trump tapped Sen. Jeff Sessions of Alabama to be his Attorney General. Sessions was one of the first in Congress to endorse Trump. He served as an advisor throughout the campaign.
Sessions is a big supporter of Airbus.
Sen. Richard Shelby, the other Alabama Senator in Congress, is also a big supporter of Trump. And of Airbus.
It’s highly likely that Sessions and Shelby will bend Trump’s ear in favor of not levying tariffs on Airbus planes.
Nov. 28, 2016, © Leeham Co.: Airbus claims that in a huge blow to Boeing and Washington State, the World Trade Organization (WTO) ruled today that the $8.7bn tax subsidy package Gov. Jay Inslee and the state Legislature approved for the 777X program is a “prohibited subsidy.”
This is the most onerous finding of illegal subsidies under WTO rules, and one that is rarely determined.
Boeing said the WTO “today rejected virtually all of the European Union’s challenges to the Washington state tax incentives” and declared a “complete victory.”
Nov. 28, 2016, © Leeham Co.: Boeing last week named an outsider, Kevin McAllister, as the chief executive officer of Boeing Commercial Aircraft (BCA).
I think this has the potential to be an invigorating move.
McAllister comes to BCA from his position as CEO of GE Aviation Services.
I don’t know McAllister and have no opinion whether he will be good, bad or mediocre. But I do like the idea of bringing an outsider in to run BCA. (My insider favorites were Stan Deal and Beverly Wyse.)

November 28, 2016, ©. Leeham Co: We covered Boom Technology’s and Virgin Atlantic’s plans to offer supersonic business class passenger traffic over the Atlantic in recent articles. In the first article, we focused on the problem areas that Boom technology must master.
The most difficult area is to find a suitable engine for the aircraft. Engines for long-range supersonic flight are quite different animals than the normal subsonic airliner engine. We will go through why the engines are different and give an example of how such an engine could look.
By creating a concrete example of an SST engine for an aircraft the class of the Boom SST, it will be possible to understand if Boom’s claim that suitable cores are available holds water, and how realistic is it to make an SST engine from these.
Note: Nov. 24 and 25 are Thanksgiving Holidays in the US. Our next post will be Monday.
Nov. 23, 2016, © Leeham Co.: The 50-seat regional jet market is dead.
That’s the conventional wisdom.
Well, not quite.
Piedmont Airlines, a unit of American Airlines, is adding the 50-seat Embraer ERJ-145 to its fleet. Eleven joined so far and next year the company plans to add 24 more.
CommutAir, an operator for United Airlines, is adding the same aircraft type to its fleet. Forty of them.
Why the mini-resurgence?
Low fuel prices and cheap airplanes.
