Pontifications: Leahy’s retirement from Airbus
By Scott Hamilton
Nov. 14, 2016, © Leeham Co.: News emerged last week that Airbus super-salesman John Leahy has a new deputy, Kiran Rao.
A new title for Rao wasn’t revealed in the Bloomberg story. He currently is EVP-Strategy and Marketing, so he already was right up there behind Leahy.
But the report, which is presumed true (Bloomberg has a good track record on this sort of thing) is pretty clear indication that the 66-year old Leahy is soon to retire and Rao is almost certainly his successor.
Leahy is Chief Operating Officer-Customers for Airbus Commercial.

Introduction
This article, which was published on the 14 November, has been updated with new information from Bombardier. The range of the CS100 from London City airport has increased due to improved performance from the aircraft and a new engine version with more thrust, the PW1535G engine.
November 14, 2016, ©. Leeham Co: In the last article about operating the Bombardier (BBD) CS100 from London City Airport (LCY), we could see that the runway is about half the length of an international airport’s runways. This will have a significant impact on the Take Off Weight (TOW) that can be used when commencing a route from London City.

The manufacturers have data in their aircraft brochures that state that one should be able to takeoff with e.g. the CS100 at Maximum Take Off Weight (MTOW) from a runway which is 1,463m/4,800ft long. London City Airport’s runway is 1,508m/4950ft long, so then things should be fine?
No, the figures from the OEMs is the planning figure for actual runway used and London City airports usable take-off Runway is given as 3,934ft. In addition there is 394ft stopping distance available.
To understand how this can be used required a bit of information that we did not have at the time of writing the original article. Some of the information we used was not up to date and we did not use the strongest engine available (PW1535G) when analyzing if an operator could fly direct between New York from London City.
Bombardier came to our help and we have now been able to update the data with which to feed our performance model. This shows among other things that it’s possible to operate a direct connection between London City airport and New York, given that the number of passengers (the payload) is restricted to around 50 passengers or below.
We have revisited the two cases, SWISS European operations from London City and how would a direct operation London-New York work. You find the updated article below.
Summary:
- London City Airport puts special requirements on the aircraft serving it.
- It puts stringent requirement for takeoff and approach/landing.
- We use new information and our performance model to present what routes can be served with a CS100 from the London City Airport.
Bjorn’s Corner: Turbofan engine challenges, Part 3
By Bjorn Fehrm
November 12, 2016, ©. Leeham Co: In our trip through a modern turbofan airliner engine and its technologies, we looked last week at the engine intake and the fan. We now continue with the compressor parts.
As compressors and turbines use the same principles (but in opposing ways), we will look at these principles this week and how their roles in the engine create their special characteristics.

As before, to make things concrete, we use a GasTurb simulation of a Rolls-Royce Trent XWB 84k engine to look at practical data when needed. As before, I have no specific knowledge about the engine and will not use any data outside what is public information.
The GasTurb cross section of a three-shaft turbofan is shown in Figure 1. We will examine the sections between station numbers (22) and (3) and (4) and (5) in the general discussion of compressors and turbines. We will then look at some data for common compressors. Read more
Bombardier 3Q2016 earnings: revenue down, performance up
Nov. 10, 2016, (c) Leeham Co.: Bombardier reported 3Q2016 and nine months results reflecting lower revenues as downsizing businesses and cost-cutting took effect.
Revenues for the current quarter were $3.7bn vs $4.1bn. For the nine months, revenues were $12bn vs $13.1bn. Earnings Before Interest and Taxes (EBIT), and before special items, were $87m vs $75m for the quarter. Losses are special items were $94m and $4.9bn.
For the nine months, EBIT was $323m this year vs $538m last year. Losses after special items were $722m and $4.66bn.
BBD burned through $320m in cash in the quarter vs $816m a year earlier. For the nine months, the cash burn was $1.56bn vs $2.37bn.

Introduction
Nov. 9, 2016, © Leeham Co.: Bombardier reports its 3Q2016 and nine month earnings Thursday and as the year prepares to enter its last 45 days, disappointment 
hangs over the company and the stock.
Summary
- Despite winning firm orders for the CSeries from Air Canada and Delta Air Lines early in the year, no other new orders have been announced.
- Deliveries of the CSeries will only be about half those projected, due to engine delivery delays from Pratt & Whitney.
- The $1bn investment from the federal Canadian government hasn’t been achieved, but an announcement may come as early as next week that an agreement has been reached.
- Boeing revised the design of the 737-7 to sit “right on top of” the CS300.
- Embraer (Brazil) is taking the government bailout of CSeries to the World Trade Organization (WTO) in inquiries, with the USA lending support.
Flying the CSeries
By Bjorn Fehrm
November 09, 2016, ©. Leeham Co: After my preparations at Bombardier (BBD) in Montreal, it was time to take an early flight to BBD’s test center in Wichita (KS) the next day. We spent the afternoon in briefings and went flying Wednesday.

The trip to Wichita was with American Airlines regional carrier American Eagle on a BBD CRJ200. Within two days, I would experience the first and smallest regional jet, the CRJ200 (albeit in coach) and Bombardier’s latest and largest jet, CS300, which encroaches on the turf of the single aisles as a direct competitor to the Airbus A319 and Boeing 737-700/7.
At the test center, just off the runway to Wichita International, I would be joined by Mike Gerzanics, who was test flying for FlightGlobal. We last met when we test flew the Airbus A350 in Toulouse in Spring 2015. Read more
Pontifications: A history-making year
By Scott Hamilton
Nov. 7, 2016, © Leeham Co.: This is a history-making year.
Yes, there is Brexit.
Sure, there is the first woman candidate of a major political party running for the presidency of the US.
Yep, there is the biggest Doofus ever nominated by a major political party also running for the presidency of the US.
But let’s get to something really important.
The Chicago Cubs finally won the World Series 108 years after the last time they did.
CSeries out of London City Airport

Introduction
By Bjorn Fehrm
November 07, 2016, ©. Leeham Co: When we visited Bombardier (BBD) in Montreal recently, we learned new information about how the CSeries would operate from London City Airport. This unique airport served 4.3m passengers last year and have expansion plans for more passengers up to 2030.
Bombardier’s first CSeries operator, SWISS Airlines, configured all its CS100 aircraft to operate from London City. This requires special engine selections and certification of aircraft and crews. The certification of the aircraft, CS100 is ongoing and will be finished at the turn of the year.

We take a look at what is required for London City and how far the CS100, appropriately configured, can serve destinations from this special airport. We will use a combination of Bombardier data and our own performance model to reach the conclusions.
Summary
- London City Airport put special requirements on the aircraft serving it.
- The CSeries will be one of the most potent types allowed at London City.
- We use BBD data and our performance model to understand at what range destinations can be served.
Bjorn’s corner; Turbofan engine challenges; Part 2
By Bjorn Fehrm
November 04, 2016, ©. Leeham Co: We will now start to go through a modern turbofan airliner engine and look at the technologies which are used and what are their technical challenges. We will start today with the engine intake and the fan.
To make things concrete, we will use a GasTurb simulation of a Rolls-Royce Trent XWB 84k engine. This will provide us with realistic example data for the different parts of the engine. I want to stress that all values are assumed as typical for such an engine. I have no specific knowledge of the Trent XWB and will not use any data outside what is public information.

The GasTurb cross section of a three-shaft turbofan is shown in Figure 1. We will use the station numbers in the figure to navigate the engine and the data from the simulation to understand modern airline engines and their typical data. Read more
Boeing sees wide-body market recovery from 2020

Introduction
Nov. 3, 2016, © Leeham Co.: Boeing may have solved its pressing problem of largely filling the production gap for the 747-8, but there is still a long way to go for the
Boeing 777X. Boeing’s view of the wide-body market has shifted. Once it thought a strong market through 2020. Now it sees recovery in demand from 2020. Boeing photo via Google images.
777.
Boeing Co. CEO Dennis Muilenburg said last week the production rate for the 777 Classic may need to come down another 1-2 per month from the previously announced 5.5/mo if sales don’t pick up.
Despite a pending order for 15 from Iran Air and the perpetual sales campaigns, Muilenburg otherwise painted a picture about wide-body demand that is anything but rosy.
Summary
- Boeing no longer sees strong demand for wide-bodies through this decade. Recovery won’t resume until the start of the next decade.
- Thus, successfully bridging the 777 Classic to the 777X becomes more challenging.
- Investors yawn at more potential 777 production rate cuts.
