A380, 10 years later

April 28, 2015: Airbus is celebrating 10 years of its A380 super jumbo.

Just about everybody else is taking pot shots at it.

There’s little doubt the airplane is a masterful achievement. But production miscues delayed the airplane by two years, the market moved on it and when it was envisioned in the late 1990s, the Boeing 777-9 wasn’t.

So 10 years after entry-into-service, and a mere 15 after the program was launched, Airbus faces a crossroads: does it re-engine the airplane on an iffy business case or can it come up with enough Performance Improvement Packages for the airframe and with the engine makers chipping in to give it new life until the market grows into the airplane–if it ever does, say detractors.

Some at Boeing we talked with are rooting for Airbus to take the neo plunge. Read more

Can PIPs bring the A380 what Emirates Airlines wants?

Introduction

26 April 2015, C. Leeham Co: With Emirates Airlines deciding for Rolls-Royce Trent 900 engines for its 50 new A380s and admitting that it would accept that this could be for all of them if Airbus does not proceed with an A380neo, the time has come to look at how much incremental improvements can be brought on the present A380.

Our proprietary aircraft model is particularly suited for such studies as we can change any parameter and read the result off the efficiency scale. We can also play with the aircraft’s configuration and see what effect it will have. Based on Emirates’ new configuration of A380s equipped with the Trent 900 engine, we have checked what incremental improvements are doable and what would they bring.

Summary

  • Our deep analysis of 18 Dec. 2014 showed that the present A380 is the most economical aircraft one can operate if one can fill it to normal load factors.
  • Emirates COO Tim Clark complements this fact with the statement, “It is Emirates’ most profitable aircraft” in the press conference in London last week when announcing the Trent 900 deal with Rolls-Royce.
  • Clark’s statement also covers the fact the passengers prefer A380 over other aircraft if they have a choice, it operates with higher load-factors then Emirates other aircraft.
  • The A380 is a rather special design and its characteristics make Product Improvement Packages, PIPs, possible in a number of areas. We discuss which they would be and model their effect on overall performance.
  • While the sought-after 10%-13% improvement would not be in there, incremental changes can cover up to half of that with more or less plausible business cases. Airbus is right now deciding which of these they see as worthwhile and introducing them.

Rolls-Royce displaces Engine Alliance for Emirates A380 order

Rolls-Royce, in a major upset, won the Emirates Airlines order to power 50 Airbus A380s ordered in November 2013. The win displaces Engine Alliance, which to now has been the sole-source provider for EK’s A380s.

Two sources confirmed the RR win. RR and Airbus did not comment on the win. EK and RR have not made any announcement. EA also did not comment.

According to one source, EK determined the RR Trent 900 was determined to be up to 4% more efficient than EA. But it’s unclear if there were other factors involved. Read more

Boeing 737 MAX: performance if engine has SFC shortfall

By Bjorn Fehrm

Introduction

14 April 2015, C. Leeham Co: There have been persistent reports that the CFM LEAP engines should be behind their fuel consumption targets. We commented on these rumors recently. It’s normal for engines to be behind final SFC to varying degree during development, this is part of the gradual development and fine-tuning of an engine until its entry into service point.

As we commented before, the key is not where an engine is two thirds through its development but if the engine would fill specification at Entry Into Service (EIS). Gaps to final specifications are normal during development, should there remain any gap at EIS it would also not be the first time this happened. Engines where target specifications are met from day one are historically in the minority. As we are in the unique situation to have a complete airliner performance model, we have modeled how any engine performance gaps would actually affect aircraft performance.

Summary

  • We have investigated what any shortfall of LEAP-1B SFC would mean for the aircraft. For situations where there would remain any deficit at EIS we choose to look at 2.5% and the rumored 4.5%.
  • Finally, we compared these two situations with a 737 MAX that would have nominal performance LEAP-1Bs and looked at the improvement in performance for all three compared to today’s 737NG.

Aviation Partners Boeing: next step–scimitar for 757, 767

Introduction

April 14, 2015: Several airlines operate the Boeing 757 across the Atlantic on “thin” routes but sometimes have to do refueling tech stops when high westerly winds

occur.

The 757s are aging, with engine maintenance, repair and overhaul costs increasing under the tightly-controlled contract with Rolls-Royce and Pratt & Whitney.

Some airlines want a “757 replacement.” Boeing and Airbus don’t see a market for “just” a 757 replacement and argue the 737-900ER/9 and A321neo/LR are the replacements. Even these fall somewhat short.

Industry observers and pontificators nonetheless are obsessed with a “757 replacement” (except us—we’ve redefined the replacement as one needed for the 225/5000 Sector [225-250 seats, 5,000 miles] and concluded an airplane very similar to the 767-200 is needed).

Patrick La Moria, EVP and chief commercial officer, Aviation Partners Boeing.

While all this debate is going on, Aviation Partners Boeing (APB) is close to seeking board approval to offer a scimitar option for the 757 that will improve efficiency by about another 1.5%. A scimitar for the Boeing 767 may not be far behind.

Summary

  • Scimitars and the increased range will eliminate some “tech” stop for fuel.
  • Field performance will be better.
  • Low fuel prices and prospect of scimitars (as well as lack of availability of new airplanes) may lead to longer retention of 757s and 767s.

Boeing MOM airliner; market coverage

By Bjorn Fehrm

Subscription required.

Introduction

12 April, 2015: In our study of the options for Boeing’s market study called Middle of the Market (MOM), we could conclude that the most likely aircraft to cover their 200-250 seat 4750nm range requirement would be a seven abreast twin aisle aircraft using their patented new oval construction, thereby saving weight and drag.

After finishing the series, Readers requested that we conclude the work by showing what market segment a family of such airliners would cover and how they would relate to the Boeing 787-8. As it is pretty straight forward to see with our aircraft performance model how much of a range of aircraft variants one can make from one base development of aircraft and engine, we decided to fulfill the wish from our Readers.

We have therefore looked at how far the concept MOM airliner could be stretched and what segment in the market would be covered by it. We also studied how much such a family would encroach on Boeing’s 787 Dreamliner market.

Summary

  • A base design such as our proposed MOM dual aisle airliner can typically cover a market of 30-40 seat increments per model.
  • Limiting factors are the base models wing area and span, together with engine sizing. Much depends on the engine’s stretch capability.
  • A MOM airliner family would compete with the 787-8 for short- and mid-haul traffic, there presenting a more economical alternative. The Dreamliner would have long-haul for itself.

Bjorn’s Corner: Intro, LCC long range and CFM’s LEAP

By Bjorn Fehrm

March 19, 2015: This is the first version of my Corner where I will comment on the aeronautical world as I see it. It will be a mix of tech things (I am an engineer) and my view on things from my European vantage point. Enough on reason and style; lets get started.

LCC goes long range: After AirAsiaX and Norwegian, now Ryanair is going long range, according to Irish Times (or not; the latest news from Robert Wall of The Wall Street Journal is that the board has not approved a long range business plan).

Be that as it may with Ryanair, the key thing is that what happened to the majors on short haul is about to hit them on long haul as well. Short haul LCCs brought about a change in airline economics and in single aisle aircraft. The LCCs, followed by Ultra LCCs, started the trend to denser and denser configurations where the latest trends are sub 29 inch pitch slim-seats and lavatories that started at 37 inch getting slimmed to 31 inch. It has also brought about changes in galleys and emergency exits configurations, all leading to aircraft with higher and higher capacities.

This is a pivotal year for the A380 as Airbus considers neo, PIPs

Introduction

March 15, 2015: This is a pivotal year for the future of the Airbus A380.

Tim Clark, the president of Emirates Airline, increased the pressure for development of an A380neo when he said he’d buy up to 200 of the prospective re-engined airplane, potentially doubling the number of neos he previously said he’d buy.

It was widely expected that if Airbus proceeds with a neo, Rolls-Royce will provide the engine. Market Intelligence, however, indicates development of the Advance engine may be running into challenges. Airbus is now talking with Engine Alliance about upgrades to the GP7200.

Summary

  • Customers take wait-and-see approach to prospect of a New Engine Option.
  • Mixing engine types a consideration for some.
  • Some at Boeing quietly rooting for Airbus to proceed.

Notes #1 from ISTAT 2015

Snippets heard in the hallways of the 2015 ISTAT annual meeting in Phoenix:

  • The Rolls-Royce Advance engine intended for the Airbus A380neo appears to be heavy, causing Airbus to return to Engine Alliance to discuss how the GP7200 might be improved. But at best the engine probably could only gain perhaps 5% better fuel consumption, well short of the 10% goal set by Tim Clark, president of Emirates Airline, the largest A380 customer. This means Airbus would have to find 5%, more or less, from the airframe–a challenge.
  • It’s still unconfirmed but appears highly likely that Swiss Airlines will be the first operator of the Bombardier CSeries. But Jon Ostrower of The Wall Street Journal beat us to the Publish button reporting the same, along with a first half EIS of the CSeries. We’ve previously estimated a 1Q2016 EIS with a slight chance of 2Q2016.

Pontifications: A350 launch aid, Emirates and the A380, Bombardier and U-Turn Al

Hamilton (5)

By Scott Hamilton

March 5, 2015: A350 Launch Aid: Boeing and the US Trade Representative got in a big twist around 2006 when Airbus said it would accept more than $1bn in launch aid from Germany for the A350. At that time, the US and European Union had recently launched the international trade complaints before the World Trade Organization (WTO), but the A350 came after the complaint was filed and the WTO refused the US request to add it to the proceedings.

Germany, in a political snit, later said it would withhold part of the launch aid because Airbus hadn’t promised the number of jobs in connection with the program to Germany that politicians wanted.
