Airbus investment resets the clock on CSeries

April 17, 2018, (c) Airfinance Journal, Montreal: Aviation Week & Space Technology managing director technology Graham Warwick believe the acquisition of a 50.1% stake into Bombardier’s CSeries will give the program opportunities in many areas.
Talking at the Innovation Aerospace Forum in Montreal, Warwick says Airbus expertise in marketing, sales and support will be “immediate benefits” to the CSeries program.
Warwick recalls that Airbus is into its second iteration of the Airbus A320 program, whilst Bombardier’s CSeries is a new product.
“The CSeries is right at the beginning of its life. It clearly resets the clock for the CSeries and can even have a meaningful impact in the future,” he says.
Bombardier’s CSeries vice president program Rob Dewar says 29 CS100/300s are now in service with three customers: Air Baltic, Swiss and Korean Air.
The Canadian manufacturer continues to be pleased with the introduction into service.
Boeing to implement structural design change in 787-8 for production commonality
April 17, 2018, © Leeham News: Boeing will implement a manufacturing shift later this year designed to bring the 787-8 into more conformity with the production of its larger siblings, the 787-9 and 787-10.

The move, involving the aft fuselage production, will reduce costs and increase commonality between the first family member and the two larger models.
The plan was first reported by David Wren of the Charleston Post and Courier.
The 787-8 became Boeing’s problem child, plagued by design and production issues that caused the entry into service to be nearly four years late. Cost overruns in the program peaked at $30bn+ in deferred production and tooling costs. Boeing will be reducing these costs for the next decade.
Air Canada sees secondary airport need for NMA

April 16, 2018, (c) Airfinance Journal, Montreal: Air Canada sees the potential of a new midsize aircraft (NMA) in its fleet to avoid congested airport.
“There is a difficulty in getting slots at key airports in key times,” Calin Ravinescu, Air Canada president and chief executive officer, said at the Innovation Aerospace Forum in Montreal.
Airlines need OEM choices: Air Canada

April 16, 2018, (c) Airfinance Journal, Montreal: The commercial aircraft manufacturing industry could head into a scenario with two major alliances: Airbus/Bombardier rivaling Boeing/Embraer, but for Air Canada, airlines need to have choices.

“This is a terrific double-edge sword. Airlines definitively need to have choice,” said Calin Ravinescu, Air Canada president and chief executive officer at the Innovation Aerospace Forum in Montreal.
Ravinescu says the idea of a single source supply is not acceptable for maintenance prospective and from a customer service prospective.
“I am totally against any notion of single sourcing, or any component in any aircraft in any circumstances. Just like our customers, airlines expect competition is the aerospace and the aircraft space.
Déjà vu all over again

Introduction
April 16, 2018, © Leeham News: There’s high turnover in the executive ranks. Major delivery delays cause disruption and unhappy customers. Airlines are cancelling and switching orders. Product strategy is challenged. Your competitor is taking advantage and making significant inroads.
If this sounds familiar, it is.
It’s déjà vu all over again.
Pontifications: Shooting yourself in your feet
By Scott Hamilton
April 16, 2018, © Leeham News: Airbus’ new top sales chief, Eric Schulz, was candid about losing American and Hawaiian airlines wide-body orders, according to a report from Flightglobal from the Airbus annual meeting.
In reference to Hawaiian’s switch of an A330-800 order to the 787-9, he admits: “Maybe we did not see the danger coming…we may have made the conclusion a bit too early that the best solution was to stick with us – which I think it was,” Flightglobal wrote.
American’s loss, Schulz told Flightglobal, was for a different reason: American was “already very heavily engaged” with the 787, adding: “I knew exactly where our competitors had to go in terms of pricing. I’m certain American did a good deal.”
I thought American and Hawaiian were predictable outcomes. But Airbus’ problem went beyond not seeing the “danger.”
FAA AD may severely limit ETOPS of some RR-powered 787s: sources

April 14, 2018, © Leeham News: An airworthiness directive from the US Federal Aviation Administration is expected as early as Tuesday that could severely restrict flight operations some of Rolls-Royce-powered Boeing 787s.
The AD is expected to require inspections and a reduction in the ETOPS long-range operation to 140 minutes from the nearest airport from 330 minutes, sources say. Inspections have to be made by May 20, according to preliminary information. If inspections fail, ETOPS may be reduced to 60, two airlines tell LNC. A third source didn’t have the numbers but said the AD is expected to be “onerous.”
Until the AD is issued and published, the numbers and conditions could change, one source tells LNC on background.
EASA, the European safety agency, issued its AD yesterday, with an April 20 effective date.
About 25% of the 787s are powered by Rolls-Royce engines, but not all engines are affected.
Leveraged Go Air plans major expansion
April 13, 2018, © Leeham News: Go Air of India is the fourth-ranked low-cost carrier by market share, with big ambitions.
The airline had only 32 airplanes at the end of last year but had more than 140 on order as of last month, presaging expansion domestically and internationally.

This compares with rival Indigo Airlines, the leading LCC, with a current fleet of 153 aircraft and orders for 380; Jet Airways (115 and 75) and SpiceJet (57 and 155). Subsequent to the end of last year, Jet place an order for 75 more 737 MAXes.
Bjorn’s Corner: Aircraft stability
April 13, 2018, ©. Leeham News: In the last Corner we discussed the pressure distribution on a conventional airfoil and compared it with a modern Supercritical airfoil. The Supercritical airfoil (which is used on all modern airliners) achieves a higher cruise Mach and a lower transonic drag by accelerating the air over the wing to a lower supersonic speed than conventional airfoils.
What conventional and supercritical airfoils share is a pressure distribution making them unstable. We need to stabilize them on an aircraft.

Narrowbody and Widebody engine developments

Introduction
April 12, 2018, © Leeham News: In an article yesterday about Long-Haul LCC costs we observed how the new Narrowbody engines are catching up to the fuel efficiencies of the Widebody engines.
Traditionally the Widebody engines were the efficiency leaders. The Narrowbody companions were designed to be durable rather than efficient.

We use the engine modelling software GasTurb to understand why this catching up of the Narrowbody engines has happened.
Summary:
- The new Narrowbody engines for Airbus’ A320 series and Boeing’s 737 MAX are close in specific fuel consumption to the new Widebody engines.
- We use the GasTurb engine modelling software to find the root cause of this change.
