June 16, 2016, © Leeham Co.: “I’m working on six or eight engines. The more the better.”
This startling statement comes from Alan Epstein, vice president of technology and the environment for Pratt & Whitney.
It runs counter to everything the airline industry has believed since the introduction of the twin-engine Boeing 767 was qualified for ETOPS in the early 1980s: fewer engines are better.
Epstein explained his statement during an interview with LNC at the United Technologies Media Days last week in Hartford (CT).
Epstein last year at the same event told LNC he was looking at four-engine technology for future airplanes. We asked him this year if he was still looking at four engines. That’s when he said he was looking at six.
It’s his job to think outside the box. This one clearly qualifies.

president of technology and the environment for Pratt & Whitney.
“The challenge to the business of the narrow-bodies is the A320s and the 737s are so learned-out that Boeing and Airbus are so efficient at building those airplanes, that their inherent cost is so low, it’s extremely difficult to move into that market,” Epstein said. “Because the learning curve, you need incredibly deep pockets and you’re going to be negative for a long time.
“I think that also applies to Airbus and Boeing,” Epstein said, referring to the prospect of a new single-aisle aircraft.

This has to come down by a factor of five, said Greg Hayes, the CEO of United Technologies, parent of PW.
This also illustrates the learning curve experienced by engine OEMs, a topic frequently discussed by the airframe OEMs but not so much by the engine manufacturers.
Hayes made the remarks at the UTC Media Day in Hartford (CT) last week. UTC is the parent of Pratt & Whitney, United Technologies Aerosystems (UTAS) and other non-aviation companies.

Introduction
June 9, 2016, © Leeham Co.: The debate continues whether the next new, clean-sheet airplane will be a Middle of the Market aircraft (MOMA) or replacements for the Airbus A320 and Boeing 737 families.
Along with he studies of new airplanes are those undertaken by suppliers. Electric Systems, a unit of United Technologies Aerosystems (UTAS), is working with the OEMs to determine what level of electric systems will be used in the new aircraft, whatever is selected to go next.

The last time this level was achieved was with the introduction of the Boeing 777, which at the same point had a 100% dispatch reliability rate.

Intelligent sensors on an aircraft have been reduced in the number on board an aircraft even as the needs greatly increase, he said. There has been a reduction of more than 50%, providing a 50% weight reduction.

Introduction
May 31, 2016, ©. Leeham Co: Airbus went through a complete review of all their aircraft programs as part of their yearly briefing for media in Hamburg today. A lot was said regarding the status for the different programs by Airbus CEO Farbice Bregier, its COO customers John Leahy and Executive VP Strategy and Marketing Kiran Rao.
The briefing was given against a backdrop of weak orders and deliveries for the first five months of the year. Both Bregier and Leahy said, “This is to be expected, it’s not sustainable that we have Book-to-Bill ratios (orders vs. deliveries) of over 1.5 or even close to two for many consecutive years. We have a backlog of 6,700 aircraft that customers expect us to deliver and they have little appetite to order new aircraft when they can earliest get them by 2021 at the earliest.
“We are now in a period of focus on deliveries and we can expect and be happy with a book to bill ratio of around one for the coming years. The extraordinary backlog also justifies our decision to increase production to 60 units per month for our A320 single aisle program.”
Here follows what was said for each of the programs.
