Bombardier’s CS100 media flight demonstrates quiet
July 10, 2016, (c) Leeham Co.: Our coverage of the Farnborough Air Show (#FIA16 on Twitter) begins today, with a media flight on the Bombardier CS100. The day was rainy and somewhat turbulent until the flight got above the clouds. Some videos are jumpy as a result.
There are several videos about the flight and some with interviews following the page break.
Quiet taxi
The first video is intended to demonstrate the quiet Pratt & Whitney engines during taxi.
Boeing MAX program progresses well
Our coverage of the Farnborough Air Show begins today with an interview with Keith Leverkuhn, VP and GM of the Boeing 737 program. There will be a combination of paywall and freewall posts.

program is going well, with the company looking for ways to add improvements to the airplane even before it enters service next year.
Improvements, which include airplane and engine components, are intended to provide dispatch reliability close to the 99.98% of the 737 NG and extend on-wing time for the reliable CFM56 engine that has powered the 737 since introduction of the 737-300 in 1984, says Keith Leverkuhn, VP and GM of the 737 program.
Summary
- Many of the major tests are completed.
- Boeing, CFM see opportunities to insert components into the LEAP-1B during flight testing to extend on-wing time from entry-into-service.
- MAX 7X (or “7.5”) can be done within the “confines” of the current MAX program.
- A larger MAX isn’t ready to go yet.
Bjorn’s Corner: Over the oceans, use FANS
By Bjorn Fehrm
08 July 2016, ©. Leeham Co: We have over the last Corners described the future Air Traffic Management systems as a combination of ADS-B and Controller-Pilot Data Link Communications, CPDLC.
What to do when there are no ground stations that can receive the ADS-B broadcast of the aircraft’s position and where it’s going? Or the aircraft’s VHF based CPDLC?
We now talk about crossing the large waters where there are no ground stations for neither ADS-B signals nor VHF communications, whether by voice or data.

The solutions over these Oceanic areas have to be based on the aircraft following predetermined tracks, Figure 1, and continuously issuing position reports to ground controllers that keep the aircraft separated along the tracks based on the reports. We now cover how this has been done historically and the way forward.
IATA, Lufthansa cargo reports are discouraging

industry.
The International Air Transport Assn. (IATA) Wednesday said yields and traffic remain under pressure. Freight tonne kilometers fell 0.9% year-over-year, IATA reported.
“Yields remained pressured as freight capacity measured in available freight tonne kilometers (AFTKs) increased by 4.9% year-on-year,” IATA said. “reight demand decreased or flat lined in May across all regions with the exception of Europe and the Middle East. These regions recorded growth in air cargo volumes of 4.5% and 3.2%, respectively, in May, compared to the same period last year.”
Lufthansa Cargo saw yields in a “landside” drop, according to a Bloomberg report.
Farnborough Preview #3: Analysts weigh in
July 6, 2017: The industrial portion of the Farnborough Air Show (#FIA16 on Twitter) officially begins Monday and runs through Thursday. There are also some special events Sunday. LNC will be reporting from the Show throughout the week.
Below are a few final previews from aerospace analysts, followed by other analyst reports for the last week. There will be no Weekly Analyst Synopsis next week because of the Show.
Highlights below:
- Expectations for orders modest-to-slow. (Credit Suisse, JP Morgan).
- Southwest MAX deferral (Credit Suisse).
- Airlines face softer environment. (JP Morgan.)
- MOM Aircraft and 777X. (Buckingham Research.)
- Spirit Aerosystems looks to A350 charge.
Book Review: The Crash Detectives
July 5, 2016, © Leeham Co.: The Crash Detectives, by Christine Negroni, © 2016. Penguin Books. Available on Amazon.com.
As an avid follower of The Smithsonian Channel’s “Air Disaster” series and The Weather Channel’s “Why Planes Crash,” as well as knowing Christine Negroni, I was anxious to read her new book, The Crash Detectives. (Negroni is also the author of Deadly Departure, about TWA Flight 800.)
Negroni is no wanna-be aviation disaster geek. Her resume qualifies her to understand aviation accidents and speak and write with knowledge about them.
Negroni writes about dozens of aviation accidents and mysteries. Some of these are well known (the de Havilland Comet I accidents, for example). Some were miraculous outcomes (United Airlines 232, US Airways 1549, Qantas Airways 32). Some are ancient history (pre-World War II, including the disappearance of Amelia Earhart.)
Among the most interesting are the accidents in which hypoxia of the pilots are involved. These make fascinating reading. And it is hypoxia that is the leading cause of Negroni’s theory of one of commercial aviation’s most infamous mystery.
Pontifications: Boeing is back
By Scott Hamilton
July 4, 2016, © Leeham Co.: It’s looking like all the pain and agony of the 787 development is behind Boeing. (Except for the deferred production costs, of course.)
Boeing is back into airplane development mode.
To be sure, only one of these is a new airplane. The others are derivatives. But at least Boeing seems to be on the move after slowing the train (to mix the metaphors) considerably following the 787 debacle.
Farnborough Air Show preview: expectations and possible surprises
Subscription Required
Introduction
July 4, 2016, © Leeham Co: The Farnborough Air Show begins next Monday and predictably, focus will be on orders.
With new airplanes from Airbus and Boeing past their development stages, conventional wisdom says there won’t be much new in this arena.
Don’t be so sure.
Bombardier is now on an upward trajectory, but don’t look for a big splash at #FIA16 (for those looking for this year’s Twitter handle). Embraer will have its E190-E2 at the show.
It’s Boeing’s 100th Anniversary and the company is rolling out the history for the show.
Summary
- No new products from Airbus.
- Boeing may have a surprise.
- Low number of orders anticipated.
Bjorn’s Corner: When it gets tough, use PBN
By Bjorn Fehrm
1 July 2016, ©. Leeham Co: Over several Corners we have described how the introduction of ADS-B and GPS will revolutionize air navigation and the ease with which bad weather take-off and landing procedures can be defined, with minimal requirements for installations on the ground.
The GPS system enables accurate enough navigation systems if extra correction systems augment the GPS signal. They then enable ILS-like landing capabilities on virtually any airport without requiring special ground installations.
There are situations where the capabilities of augmented GPS systems are not good enough. When local terrain requires that approach or departure procedures to and from an airport be flown in a narrow corridor with curved paths, we need to step up to Performance Based Navigation.

We will now go through what Performance Based Navigation is and how it differs from the GPS- based RNAV navigation we have described so far and when it will be used.
Boeing launches PFS 2.0
Update, 0815 PDT July 7: Boeing Corporate Headquarters responded to our questions. The transcript has been added to the article below.
Boeing wasn’t shy about who it targeted, or punished. Even supply-chain giant United Technologies was placed on Boeing’s no-fly list when it balked at the onerous demand.
Now Boeing is moving forward with PFS 2.0, a second round of demands.
