Odds and Ends: AF 447 resurfaces; Racing toward 2,000; A400M; beating back anti-droners
Air France 447: More data has surfaces on Air France 447, the Airbus A330 that plunged into the Atlantic on a flight from Brazil to France several years ago. In a cooperative post-investigation that included Airbus and Boeing, efforts to replicate the crash in a simulator failed.
It separately emerged that the pilot of the flight had one hour of sleep and the co-pilots also didn’t have the requisite sleep.
Racing Toward 2,000: At ISTAT, Airbus COO Customers John Leahy said he expected to gain another 200 orders this month for the A320 family, reaching 2,000 orders for the neo in the process. Lufthansa and Turkish have since announced orders.
A400M certified: The troubled Airbus A400M has been certified.
Beating back anti-droners: Boeing and supporters killed legislation in Washington State that would have outlawed drones. Boeing’s subsidiary Insitu is headquartered in Washington and considered leaving to Oregon, across the Columbia River. A coalition is also working to have Moses Lake (WA) selected as a drone testing site under an FAA program.
Boeing’s webcast from Japan on 787 battery fix
Ray Conner, CEO of Boeing Commercial Airplanes, Mike Fleming, VP and Chief Engineer for EIS of the 787 and Mike Sinnett, vice president and chief project engineer for the Boeing 787, provided an update on the battery fix during a visit to Japan today (or tomorrow, Japan time….)
Here is a running brief of comments:
RC Ray Conner
MF Mike Fleming
MS Mike Sinnett
RC: US FAA has a comprehensive process we must follow to get airplanes into the air for testing and for re-EIS.
We’re here this week to discuss our solution and to take feedback from Japanese authorities, The solution is the result of thousands of hours of tests within Boeing and with other agencies.
We acknowledge the work of the Japanese regulators and GSD Yuasa and have been a tremendous partner throughout this process. I speak for the 170,000 employees of Boeing when we say that the safety of our product is the #1 priority of the company, ahead of everything else we do.
We have three layers of solutions and we are confident these are the right ones.
MS: (Going through the PDF slides linked above.) We understand that we do not have a business if we don’t have safety. Safety is the number one thing we think of in designing an airplane.
With 100 years of experience, we apply these lessons to each new airplane. We stand behind the integrity of each Boeing airplane.
The battery is only a backup in flight. It operates on the ground. The 787 is an electric jet, using two generators in combination producing one megawatt of electrical power. The APU also has two generators associated with it.
If in the unlikely event all generators and batteries fail, the Ram Air Turbine deploys. We don’t need the main battery in flight or the APU battery in flight for safety. The batteries operate the brakes on the ground and other ground-based functions.
The Li-Ion batteries technology was already mature technology for many applications, including aerospace (not commercial aerospace).
[Note: Bombardier reached a different conclusion, telling us that in 2009 when it had to make a decision on batteries that it was not satisfied with the Li-Ion technology, and therefore selected nickel-cadium.)
Li-Ion technology earned its way on to the 787.
We work very hard to design a system that will not fail Then we assume it will fail and provide redundancies or backups. We apply this design philosophy to every system on the airplane.
Odds and Ends: RR–We lost 777X; 787 webcast on battery fix
Engine Selection on 777X: Rolls-Royce tells us it’s out as a supplier for the Boeing 777X. Pratt & Whitney earlier withdrew from the competition, deciding there wasn’t a business case to be second fiddle to GE, which was presumed by RR and PW to a sure bet to be a supplier even if Boeing went with a dual source engine option. All this means, of course, that GE and its GE9X will be the sole source engine on the new airplane.
Marc Birtel, in an email statement, neither confirmed or denied the news.
“We are following a disciplined development process for the 777X and will make announcements regarding suppliers at the appropriate time. Our decision regarding engine options will be based on the right technical solutions available at the right time under the right business arrangements to meet our customers’ requirements.”
Boeing webcast on battery fix: Boeing has a webcast open to all at 6pm PDT today about the battery fix for the 787.
Special ‘task force’ studied lithium-ion batteries long before JAL 787 incident
A special task force was studying issues relating to the use of lithium-ion batteries in airliners long before the January 2013 Japan Air Lines fire. The effort began in 2008 and it met in December 2012, one month before the JAL fire.
Boeing, the FAA, Embraer, Airbus, GS Yuasa, American Airlines and ALPA are just a few who participated in these meetings, according to documents.
Randy Tinseth, VP Marketing for Boeing, referred to the group when he discussed the FAA approval to proceed with the Boeing plan to fix the 787 battery issues in his blog, here.
Tinseth writes:
The certification plan calls for a series of tests that show how the improved battery system will perform in normal and abnormal conditions. The test plans were written based on the FAA’s standards as well as applicable guidelines published by the Radio Technical Commission on Aeronautics (RTCA), an advisory committee that provides recommendations on ways to meet regulatory requirements. The RTCA guidelines were not available when the original 787 battery certification plan was developed.
We asked Boeing what the document was that Tinseth referred to above: it is a document numbered DO-311. There are a number of documents at RTCA containing the reference to DO-311.
DO-311 is described by RTCA as:
FAA approves Boeing plan for 787 battery fix; it is a “path” to resume service
From the FAA:
The Federal Aviation Administration (FAA) today approved the Boeing Commercial Airplane Company’s certification plan for the redesigned 787 battery system, after thoroughly reviewing Boeing’s proposed modifications and the company’s plan to demonstrate that the system will meet FAA requirements. The certification plan is the first step in the process to evaluate the 787’s return to flight and requires Boeing to conduct extensive testing and analysis to demonstrate compliance with the applicable safety regulations and special conditions.
“This comprehensive series of tests will show us whether the proposed battery improvements will work as designed,” said Transportation Secretary Ray LaHood. “We won’t allow the plane to return to service unless we’re satisfied that the new design ensures the safety of the aircraft and its passengers.”
The battery system improvements include a redesign of the internal battery components to minimize initiation of a short circuit within the battery, better insulation of the cells and the addition of a new containment and venting system.
“We are confident the plan we approved today includes all the right elements to conduct a comprehensive evaluation of the battery system redesign,” said FAA Administrator Michael P. Huerta. “Today’s announcement starts a testing process which will demonstrate whether the proposed fix will work as designed.”
The certification plan requires a series of tests which must be passed before the 787 could return to service. The plan establishes specific pass/fail criteria, defines the parameters that should be measured, prescribes the test methodology and specifies the test setup and design. FAA engineers will be present for the testing and will be closely involved in all aspects of the process.
The FAA also has approved limited test flights for two aircraft. These aircraft will have the prototype versions of the new containment system installed. The purpose of the flight tests will be to validate the aircraft instrumentation for the battery and battery enclosure testing in addition to product improvements for other systems.
The FAA will approve the redesign only if the company successfully completes all required tests and analysis to demonstrate the new design complies with FAA requirements. The FAA’s January 16, 2013 airworthiness directive, which required operators to temporarily cease 787 operations, is still in effect, and the FAA is continuing its comprehensive review of the 787 design, production and manufacturing process.
From Boeing:
Odds and Ends: Tanker-like redux; Ryanair’s 200 737s; new use for Winglet
Tanker-like Redux: As you read this story, it sounds a lot like Boeing vs EADS, right down to the build-it-in-the-USA element.
Ryanair’s 200 737s: News emerged that Ryanair will firm up an order soon for 200 Boeing 737s. This has been hanging “out there” for some time. We learned of this likelihood a couple of months ago. It was all hush-hush while Ryanair took another run at Aer Lingus.
Pan Am landmark: For those filled with nostalgia, this news is sad: the famed Pan Am Worldport faces the wrecking ball.
New Winglet use: This is pretty cool. Via Steve Trimble of Flight Global.
Odds and Ends: 777X ATO next month, says AvWeek; 787 and the FAA; A318
777X ATO: Aviation Week reports that Boeing’s Board will grant Authority to Offer the 777X at the next meeting, in April.
Emirates Airlines has previously said it will order 100 or more of the X to begin replacing its 777-300ERs. Lufthansa and Air Lease Corp are likely co-launch customers.
Update: The Wall Street Journal now has an article identifying British Airways and Japan Air Lines as possible launch customers.
787 and the FAA: The FAA is expected to green light this week going forward with Boeing’s proposed fixes for the battery issues in the 787, but this doesn’t mean the challenges are over for Boeing. Extensive lab and flight testing will be required, meaning it still will be some time before the grounding is lifted.
A318 Done: Bloomberg has a story about the Airbus A318 and its dried-up sales. It was never a good seller.
