Toulouse 13 Jan 2015: Airbus today held their annual press conference where they among other things revealed their final numbers for orders and deliveries. The press conference was hosted by Airbus CEO Fabrice Bregier accompanied by COO Customers John Leahy, new COO Tom Williams and new Head of Programs Didier Evrard.
Airbus in 2014
Bregier started with pointing out that 2014 was a very eventful year for Airbus. Airbus did their customary end of year sprint and passed Boeing for net orders with 24 aircraft netting 1456 commands, Figure 1.
On the delivery side Boeing is ahead with 723 deliveries versus Airbus 629, Figure 2.
Further Airbus certified the A350 and delivered the first aircraft to its launch customer, Qatar Airways. It also launched the A330neo and got 120 orders during the year. Finally they flew the A320neo first prototype.

Jan. 12, 2015: One of the subjects which is sure to come up on Airbus annual press conference on Tuesday the 13th in Toulouse will be when and how Airbus will re-engine the A380.
Airbus Commercial CEO Fabrice Bregier vowed during the Airbus Group Global Investors Day last month that an A380neo is coming.
There is much speculation around this subject as the business case of re-engineering an aircraft that is selling at such low numbers is difficult to get to close. The business case is difficult to make work for Airbus (such a project will cost in the order of $2 billion) but it will be equally hard for the engine manufacturers to offer engines that have enough efficiency gain to make the overall project feasible from an efficiency improvement perspective.
Here’s a visualization of events to look for in commercial aviation in 2015.

Dec. 21, 2014: Last week we did a deep analysis of A380 and its competition. It has been windy weeks for the aircraft since the Airbus Global Investor Forum and it was time to bring some needed facts on the table. These facts showed there is a clear difference between the hype being perpetuated in the media and the reality. As we cleared the situation around the A380, we also touched on the large twins that could fulfill at least parts of its missions.
There has been a lot of discussion around these aircraft as well as they form the battle of titans one level down from A380, the large, long-haul market today dominated by Boeing’s 777-300ER (the A380 does not have a real competitor–the 748i is clearly smaller, in fact so much smaller that it will be engulfed by the 777-9X).

Dec. 18, 2014: In our Monday article we go behind the scenes of the doubts that were spread over the A380 by Airbus last week. To complete the picture we now update our competitive analysis that we did in February this year. We then compared the A380 to Boeing’s 747-8i, the 777-300ER and the forthcoming 777-9X. We also included Airbus closest aircraft, the A350-1000.
A lot has happened since then. Airbus has done a lot of work on the passenger area of the A380 to offer increased passenger densities and the pictures of the emerging Boeing 777-9X and Airbus A350-1000 is now clearer.
Sales efforts of the A380 has also progressed, with meager results despite adding a leasing proposition what should make the hurdles of operating a small sub-fleet of A380s lower. To understand why, we interviewed Mark Lapidus, the CEO of Amedeo, the leasing company which specializes in financing and leasing of A380s. We wanted specifically to talk to Lapidus about the reactions of the airlines to the A380 and what problems he saw in selling an aircraft of this type.
In preparing the article we also gathered additional info from Airbus and Boeing, from the former around their work on the cabin configurations and densities, from the latter the maintenance costs for the up and coming 777-9X.
As we did this deeper study, a more nuanced and different picture emerged from the one seen in February. The results busts a number of deeply engraved myths, one being that four engines are more expensive to fly and maintain than two.
Dec. 16, 2014: There have been record aircraft orders year after year, swelling the backlogs of Airbus and Boeing to seven years on some product lines, Bombardier’s CSeries is sold out through 2016, Embraer has a good backlog and the engine makers are swamped with new development programs.
So it is with some irony that several Original Equipment Manufacturers (OEMs) are warning of cash flow squeezes in the coming years.

Dec, 8, 2014:The Boeing 737-8 MAX is the successor to the 737-800 and has largely been thought of in this context.
Our analysis, prompted by Norwegian Air Shuttle (NAS) plans to use Boeing 737-8 MAXes to begin trans-Atlantic service on long, thin routes, comes up with a conclusion that has gotten little understanding in the marketplace: the 8 MAX has enough range and seating to open a market niche below the larger, longer-legged 757, and the economics to support profitable operations for Low Cost Carriers interested in some trans-Atlantic routes or destinations beyond the range of the -800.

Dec. 2, 2015: The time has now come to cover descent and landing in our articles around airliner performance. As many aspects of descent are similar to climb we will repeat a bit what we learned in Part 4:
Lets now start to go through the steps that our 737 MAX 8 performs after leaving its cruise altitude.
Nov. 30, 2014: MTU Investors Day: MTU is a major participant in engine development and supplies, participating on the GEnx, GTF and GEnx program. It’s also a member of the joint venture in International Aero Engines and it’s a major player in the aftermarket Maintenance, Repair and Overhaul (MRO) sector, providing a serious competitive alternative to the aftermarket contracts offered by the engine OEMs. Its held an investors day conference Nov. 25. Highlights included:

In our first article on how to understand the fundamentals that make up airliner performance we defined the main forces acting on an aircraft flying in steady state cruise. We used the ubiquitous Boeing 737 in its latest form, the 737 MAX 8, to illustrate the size of these forces.
Here a short recap of what we found and then some more fundamentals on aircraft’s performance, this time around the engines:
When flying steady state (Figure 1) we only need to find the aircraft’s drag force to have all important forces defined.
The lift force is given as equal to and opposite to the aircraft’s weight and the tail downforce that we need to add to this was small. We also presented the two classes of drag that we will talk about:
We could see that the aircraft’s flight through the air created a total drag force of 7900 lbf, Figure 2 ( lb with an f added as we prefer to write it as this is a force and not a measure of mass. Mass we denote with just lb or the metric units kg or tonne = 2205 lb).
We also learned that if the drag is 7900 lbf then the engine thrust is opposite and equal. It is then 3950 lbf per engine when cruising at our mean cruise weight of 65 tonnes or 143.000 lb on our 1000 nm mission. Drag due to size consumes 63% of our thrust and drag due to weight 37%. Read more
