February 24, 2017, ©. Leeham Co: After having analyzed how the engine gets stressed during different phases of flight, we now look into how engines are used. The de-rating of engines for takeoff is important, as not 100% thrust is needed for all takeoffs. If the aircraft is lightly loaded or is taking off from a long runway, with low temperatures or altitude, the engine can be thrust de-rated so that it experiences less stress.
Once in the air, the engine is run below maximum settings by use of cost-index. These actions will result in less fuel usage and also longer engine operation between overhauls. We will now finish the operations part of our engine clinic with how airlines keep the engines away from the workshops by swapping the engines between fleet aircraft.
A visit to the engine workshop costs in the millions of dollars, so the longer the engine can operate before a shop visit, the better. Read more
Feb 23, 2017, (c) Leeham Co.: A Boeing company, Inventory Locator Service, yesterday posted an Evolution of Boeing graphic on its website that traces key points in
Boeing’s history.
There was a problem, however: the airplane at the top of the graphic, which was photo-shopped with Boeing 737 identification, was an Airbus A321.
A Twitter storm immediately commenced after one person saw the Evolution and posted it on his Facebook page.
It isn’t the first time an Airbus airplane showed up in a Boeing-focused promo piece. The promo piece was still up last night, but may not be when the company opens for business in the Midwest today.
The graphic is posted below the jump in this post.
The A321 wasn’t the only problem. A 747-8 was used to represent the first flight of the 747-100. A 737NG freighter represented the first flight of the 737, which was the -100 series. A 787–which didn’t even exist at the time–was used to represent the 1997 merger with McDonnell Douglas. And a 777F was used to represent the first flight o the 78.
This isn’t the first time an Airbus A320 was used to promote Boeing.
In November 2013, the Washington Aerospace Partnership (“WAP,” as in upside the head, somehow seemed fitting) used an A320 in a full page Seattle Times advert touting the state as the best place in the US to do aerospace business.

February 24, 2017, ©. Leeham Co: Airbus Group (“Airbus”) presented results for 2016 in line with guidance. The Airbus CEO Tom Enders said, “This is the best Airbus, ever.”
Yet everything was not as expected; most of the press conference was spent on how the sins of the old Airbus still haunt the present company.
The problem areas, A400M and A380, both stem from the same time period, 2000-2003.
This was when the old, non-integrated Airbus wanted to show the world it could build the largest, most capable aircraft. The resulting lighthouse projects, A400M and A380, are still not out of the woods. Read more

February 22, 2017, ©. Leeham Co: Ryanair is Europe’s airline with the lowest fares. And it’s the most profitable, despite growing faster than even the Middle East carriers (growth needs money).
It’s time to dive deep in this locomotive. I even flew their business class before writing the report, to understand what is going on. Read more
Feb. 20, 2017, © Leeham Co.: Boeing’s long-term messaging that all is well isn’t resonating with a number of industry analysts and observers.
To be sure, today and in the short-term, Boeing’s stock is on a steady upward trajectory.
But aerospace analysts are not buying into the long-term message.
Neither did three speakers at last week’s annual Pacific Northwest Aerospace Alliance (PNAA) conference in Lynnwood (WA), including me.
Consider:
February 17, 2017, ©. Leeham Co: In our journey of an airline engine’s life, we will now look at the maintenance which is necessary to keep it fit for flight.
An engine is only in top condition once in its life, at delivery. As soon as it’s operated on the aircraft, in-service wear of its different parts will reduce its performance.
The engine manufacturer’s prescribed maintenance is designed to keep the engine in good health during its life, despite all its hardship. Read more
