Bjorn’s Corner: The role of a Flight Management System

 

By Bjorn Fehrm

15 April 2016, ©. Leeham Co: In several of my Corners when describing flight control systems and autopilots for airliners, I have written about the aircraft’s Flight Management System (FMS) without actually describing its role completely.

The first complete FMS was introduced with the Boeing 767 in 1982. Before the Boeing 767, aircraft cockpits had at least three flight crew members, the third being the navigator or flight engineer. This third person managed a number of tasks. He surveyed the aircraft’s systems/engines and performed the navigation for the aircraft.

With the introduction of computerized support systems for system monitoring and warning (EICAS for Boeing, ECAM for Airbus) and navigation (FMS for both Boeing and Airbus), the third person could be replaced and two flight crew cockpits became the norm.

When flying a modern airliner, the FMS has a central role in both flight preparations and during flight. We will therefore describe what an FMS does in more detail. Read more

Introduction

April 14, 2016, ©. Leeham Co: Bombardier is working hard to get additional mainline airline customers for its C Series project. The latest discussion is whether Delta Air Lines would replace its fleet of Boeing MD-88s with the C Series.

In this context, it’s also discussed if the largest model, the CS300, Figure 1, is large enough for Delta. This aircraft seats 135 passengers in a two class configuration and up to 160 passengers in an all economy high density version.

The question is whether this is sufficient for Delta and other mainline customers, or if a still larger version is needed in the program, the oft-discussed CS500. We decided to use our proprietary aircraft model to see if a CS500 would be straight forward for Bombardier to develop, should Delta or any other customer ask for a three model C Series program.

Summary

  • The C Series aircraft program was developed with the CS300 as the main model. The wing, engine and landing gear were dimensioned with the CS300 in mind.
  • The CS100 is a shrink of the CS300, and not vice versa (the CS300 a stretch of the CS100).
  • A tentative CS500 stretch if therefore a first stretch of the program’s main model and not a double stretch of a CS100.
  • This is evident when one starts to analyze how a CS500 would be designed. There are rather modest changes that need to be done to create an extended model that seat up to 180 passengers.

Alcoa lowers guidance, cites slowing jet sales, production ramp up

April 13, 2016, © Leeham Co.: Alcoa, a major supplier to Airbus and Boeing, lowered its 2016 guidance on anticipated lower demand for aluminum on lower orders for legacy commercial airliners and a slower than expected transition to new airplanes.

In a first quarter earnings call Monday, Alcoa didn’t specify which of the Big Two OEMs it was thinking of, or whether these might have been Bomabrdier and Embraer, for which it also is a supplier. But Sam Pearlstein, the aerospace analyst for Wells Fargo, believes it is Airbus and the A320/A350 programs.

“Alcoa reduced 2016 aerospace global sales growth guidance to 6-8% from 8-9% with large commercial aircraft growth now expected to be about 9% (vs. 15% previous forecast) largely due to lower orders for legacy models and a ”more careful” ramp-up of new models (which we presume means A320NEO and A350),” Pearlstein wrote in a note published yesterday.

Prices set for years, Boeing cost-cutting goes straight to bottom line

April 12, 2016: Prices for Boeing and Airbus planes are set through the remaining decade, meaning any cost-cutting being pursued by Boeing will flow straight to theBoeing Logo bottom line, a new note issued yesterday from Bernstein Research concludes.

“Pricing on more than 80% of deliveries is already set through the decade,” the note says. “Despite the competitive pressures, however, the reality is that most of the competitive situations are about deliveries in the next decade. This creates a situation in which most of every dollar of cost savings will flow to margin during this decade because most of the planed deliveries are already priced. The same is true for Airbus.

“This has not been the case in prior cycles because backlogs then tended to be only about three years of production, rather than the eight years that we see today. In those cycles, Airbus and Boeing would cut costs, but then compete away the value. That price competition will now be happening primarily on deals for delivery after 2020,” Bernstein says.

Why Boeing won’t take a charge on 787s

Introduction

Boeing 787-9. Source: Boeing.

April 11, 2016, © Leeham Co.: Boeing has $29bn in deferred production costs and another $3bn in deferred tooling costs for its 787. The accounting block, for its program accounting, is a record 1,300 aircraft. Many Wall Street analysts are skeptical whether Boeing will ever recover the huge deferred numbers.

Boeing insists it will.

Still, taking a charge of some number—as it has done twice for the 747-8 and twice for the 767-based KC-46A—is something Boeing repeatedly insists it doesn’t need to do.

Why not?

There are a few key reasons, say Wall Street analysts who follow Boeing: revenue, cash flow and the stock price.

Summary

  • Bank of America Merrill Lynch estimates Boeing needs to post a profit of $30m on each of the remaining 900 787s to be delivered to recover the deferred costs. LNC figures this number is higher.
  • Pricing pressure from Airbus makes it difficult to obtain this profit.
  • The deferred costs limit Boeing’s ability to price down to meet Airbus’ offers to customers.
  • Credit Suisse figures Boeing can recover only some $22bn of $29bn in deferred production costs.
  • Boeing warns in SEC filings a forward loss might be required.
  • But no forward loss is likely unless revenue falls short.

Pontifications: Catching up on the KC-46A, KC-30A

Hamilton KING5_2

By Scott Hamilton

April 11, 2016, © Leeham Co.: The Government Accountability Office (GAO) concludes that the Boeing KC-46A aerial refueling tanker for the US Air Force has “challenging testing and delivery schedules” ahead in its annual review of the program.

It’s been a long, long time since I wrote about aerial refueling tankers. Having delved into this topic during the long-running saga of the USAF recapitalization effort, and the competitions between Northrop Grumman/EADS and later Airbus alone and Boeing, the topic had been beaten to death.

But as we who follow such things know, Boeing’s current effort to build the winning KC-46A for the Air Force has run into more than a few problems. These have led Boeing to be at least eight months late and write off $1.2bn pre-tax on the program.

And the problems aren’t over.

Inflight Internet

By Bjorn Fehrm

06 April 2016, ©. Leeham Co., Hamburg, Germany: On the second day of the Aircraft Interior eXpo, AIX 2016, we checked out the In-flight Internet situation. What interested us was why is there such lousy Internet performance on many airlines today and what will be done about it over the next few years. We got a good picture on why things are as they are and how this will change within quite a short time.

Rather than go through what a lot of vendors will do, we will try to describe the root problems involved and what is done by the industry to change that. We will also mention some of the key players that are attacking the subject.

But let’s start with the problem. Figure 1 shows where the world’s main airline routes are right now.

As can be seen, the world air traffic is not very evenly distributed. One third of the world has intense traffic and two-thirds not so much or none at all. Read more

Trends in cabin amenities

By Bjorn Fehrm

05 April 2016, ©. Leeham Co: We are at the Aircraft Interior eXpo, AIX 2016, to check out what’s new where the aircraft meets the passenger. We got to the expo in Hamburg on a full Lufthansa A320 flight. It was the usual struggle for the last passengers boarding to find place for their roller bags in the overhead bins.

Airbus showed the new overhead bins for the A320 at the show, Figure 1. They will be a big relief for the airlines and passengers, just like the Space-bins announced by Boeing at last year’s show.

As can be seen in the picture the passengers don’t get quite the nice airy feeling which is part of Boeing’s Sky interior. The shape of the bins are rather like the present day product but with the A350 style curvature to the other section.

It thereby will bring a bit lighter feel to the cabin but most importantly more space for carry on luggage. Roller bags can be stored standing on the side and this increases the capacity with over 50%. The first delivery of the new bins was to Delta for their new A321 last month. As can be seen in the picture mood LED lighting is also part of the A320 cabin upgrade. Read more

Alaska, Virgin confirm merger

AS_VX MapApril 4, 2016, (c) Leeham Co.: Alaska Air Group and Virgin America confirmed weekend reports that they reached a deal to merge.

The replay of the Alaska webcast/conference call, with slide show, is here.

Rationale includes what LNC outlined in our March 29 post: growth, access to more gates and slots. Alaska officials said Virgin’s presences in California, combined with Alaska, will give Alaska to #1 market share position on the US West Coast, passing Southwest Airlines’ 21% by one percent.

Here are some highlights from the conference call:

Boeing has lost neo/MAX battle; time to refocus goals

Subscription Required

Introduction

April 4, 2016, © Leeham Co.: Boeing should forget about competing with Airbus for market share.

The Airbus A320neo. Airbus has won the single-aisle battle between the neo and Boeing 737 MAX. Boeing needs to refocus its goal. Photo via Google images.

Airbus already has won the neo/MAX battle. This is a battleground Boeing will not retake for the lives of these airplanes.

Airbus has led Boeing in wide-body, passenger airplane sales for most of the past several years. (Boeing smashes Airbus in wide-body cargo aircraft sales.) This sector will remain competitive.

Instead, Boeing should concentrate on profit margin and roll the dice on a clean-sheet, new single-aisle airplane as its best hope of recovering the dominance it long held over Airbus.

Summary

  • Airbus has won the single-aisle competition with the A320neo family. Boeing has no hope of catching up in the next 10 years.
  • Airbus is competitive in wide-body sales (excluding freighters). This is the new battleground.
  • Boeing should “maintain” 737 market share and focus on margin across the 7-Series instead.
  • Boeing’s hope to regain the leadership in the single-aisle sector is the next generation aircraft.
