February 3, 2017, ©. Leeham Co: In the last Corner, we went through how our airliner engine reacts to the different phases of flight, including what happens when we operate in a hot environment.
We also showed how engine manufacturers make a series of engines with different thrust ratings by de-rating the strongest version through the engine control computer.
We will now look deeper at how engines are controlled and why so-called flat-rating is important. Read more

Feb. 2, 2017, © Leeham Co.: Embraer’s new E2 jet faces a major challenge: the US pilot Scope Clause that limits the number, seats and weight of aircraft that can by operated by regional airlines on behalf of the US legacy carriers.
The E175 E2 exceeds the 86,000 lb weight limit in the Scope Clause. Unions declined last year to adjust this limit upward. The next round of contract talks begins in 2019.

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
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.
Jan. 30, 2017, © Leeham Co.: Two of the seven countries on President Trump’s own “no-fly” list of travelers coming to the United States committed to 108 Boeing airplanes.
One of the governments is an ally of the United States: Iraq.
Iraq remains on the US government list of a terrorist state. Iran, Sudan, Somalia, Libya Yemen and Syria were targeted in Trump’s Executive Order Friday as presenting terrorist threats to the US.
Airline flight crews who come from these countries, even if flying for airlines not of these nations, are affected, said the International Air Transport Assn. (IATA), an industry trade group.
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

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.
Jan. 25, 2017: Boeing today reported slightly lower revenues for 2016 vs. 2015.
Revenues were down 2% to $94.6bn vs $96.1bn.
Net profit was down 5% year-over-year, reflecting the lower revenues and after charges on the KC-46A tanker and 747-8 programs. Operating profit was $5.8bn vs $7.4bn.
Net profit under GAAP accounting was $4.4bn vs $5.2bn.
Boeing took a pre-tax $312m charge on the KC-46A in the fourth quarter. Charges are now approaching $2bn.
The full press release is here.
Note that officials will make a decision this year whether to increase 787 production to 14/mo by the end of the decade (see Highlights).
Jan. 24, 2017, © Leeham Co.: SkyWest Airlines, which stunned the aviation community in 2010 with an agreement to order 100 Mitsubishi MRJ90s and options for 100 more, is sticking with the airplane so far in the wake of another delay.
The Japanese company Monday announced a new delay of two more years, making a total of seven. Entry-into-service with launch customer ANA is now slated for 2020. Before this announcement, SkyWest was slated to receive its first airplane in 2019.
“Our conditional firm orders of the MRJ aircraft remain unchanged, and are dependent on flying contracts and scope availability,” a spokeswoman said in an email to LNC.
Mitsubishi lists the SkyWest order as firm on its web site.
