Bjorn’s Corner: Over the oceans, use FANS
By Bjorn Fehrm
08 July 2016, ©. Leeham Co: We have over the last Corners described the future Air Traffic Management systems as a combination of ADS-B and Controller-Pilot Data Link Communications, CPDLC.
What to do when there are no ground stations that can receive the ADS-B broadcast of the aircraft’s position and where it’s going? Or the aircraft’s VHF based CPDLC?
We now talk about crossing the large waters where there are no ground stations for neither ADS-B signals nor VHF communications, whether by voice or data.

The solutions over these Oceanic areas have to be based on the aircraft following predetermined tracks, Figure 1, and continuously issuing position reports to ground controllers that keep the aircraft separated along the tracks based on the reports. We now cover how this has been done historically and the way forward.

industry.
The International Air Transport Assn. (IATA) Wednesday said yields and traffic remain under pressure. Freight tonne kilometers fell 0.9% year-over-year, IATA reported.
“Yields remained pressured as freight capacity measured in available freight tonne kilometers (AFTKs) increased by 4.9% year-on-year,” IATA said. “reight demand decreased or flat lined in May across all regions with the exception of Europe and the Middle East. These regions recorded growth in air cargo volumes of 4.5% and 3.2%, respectively, in May, compared to the same period last year.”
Lufthansa Cargo saw yields in a “landside” drop, according to a Bloomberg report.
Bjorn’s Corner: When it gets tough, use PBN
By Bjorn Fehrm
1 July 2016, ©. Leeham Co: Over several Corners we have described how the introduction of ADS-B and GPS will revolutionize air navigation and the ease with which bad weather take-off and landing procedures can be defined, with minimal requirements for installations on the ground.
The GPS system enables accurate enough navigation systems if extra correction systems augment the GPS signal. They then enable ILS-like landing capabilities on virtually any airport without requiring special ground installations.
There are situations where the capabilities of augmented GPS systems are not good enough. When local terrain requires that approach or departure procedures to and from an airport be flown in a narrow corridor with curved paths, we need to step up to Performance Based Navigation.

We will now go through what Performance Based Navigation is and how it differs from the GPS- based RNAV navigation we have described so far and when it will be used.
Southwest’s MAX deferral
- Bloomberg News reports that Boeing is mulling a 777-10. We hinted at this last July with the large GE9X development. See our Paywall Farnborough preview this coming Monday for more information.

June 29, 2016, © Leeham Co.: News last week that Southwest Airlines deferred 67 Boeing 737 MAX deliveries three year caused some to conclude that this is a harbinger of bad news for Boeing and the MAX program.
LNC disagrees with this conclusion.
Summary
- Southwest says it’s about not having a “subset” fleet of the 737 Classic when the MAX enters service.
- The airline also says it needs to spend more on technology, an area where WN has long lagged its competitors.
- Accelerated retirement of the 737-300/500 is a key reason for the fleet planning changes.
- Long-standing fatigue issues with the Classic remain a problem.
Analysts opine on Airbus, Boeing, Iran and Brexit
Click on image to enlarge.
June 24, 2016: Brexit continues to creep into US analyst reports for the potential impact of companies doing business in the United Kingdom.
But there are other issues as well. Highlights this week:
- Spirit Aerosystem is a supplier to Airbus and Boeing. Deliveries to Airbus for the A350 continue despite program delays. Negotiations continue with Boeing over new contract terms. (Buckingham.)
- Don’t freak out over the Southwest Airlines deferral of Boeing 737 MAX. (Credit Suisse.)
- The Iran deal isn’t a big deal yet for Boeing. (Goldman Sachs.)
- Brexit may benefit B/E Aerospace. (JP Morgan.)
- US trans-Atlantic airlines likely will be hurt by Brexit but purely US domestic carriers are fine. (Morgan Stanley.)
Brexit special: analyst reaction
Source unknown. Via Twitter.
June 27, 2016: Aerospace and airline analysts are reacting to Thursday’s vote in Britain to leave the European Union. Below is a synopsis of some of the analyst notes we receive.
Credit Suisse
We are forwarding the analysis our European Transports team put out this morning on Brexit and have a few observations as it relates to US Airlines.
- GBP Exposure: For the US network carriers (UAL, DAL, AAL), GBP exposure averages ~2-3% of total revenues with overall UK exposed revenues ranging 4-6%.
- Impact to High Yield Transatlantic Traffic Primary Concern: For US network carriers, we see the primary concerns post-Brexit on the demand implications on the Transatlantic. Last week IAG issued a profit warning which worries us on corporate demand weakness. Given scheduled seat growth in the Transatlantic continues to outpace demand (H2 seat growth US-EU scheduled at 8.6%), capacity cuts are needed to stabilize pricing particularly since UK GDP is likely to slow even further. We look to Q2 earnings calls next month for additional color from carriers.
- AAL Viewed Most at Risk Given Partnership with IAG, but Our Team Believes IAG is Least at Risk [among EU airlines] from Future UK-EU Air Service Negotiations: Our European analyst believes IAG’s airlines would see limited effect from the UK exiting the EU Open Skies agreement as long as renegotiated UK-EU bilaterals do not limit service levels. This suggests that AAL’s relative underperformance was overdone on Friday; however, we expect Brexit-related uncertainty to continue to weigh on network carriers, and reiterate our confidence in domestic carriers (Outperform on LUV & SAVE).
Bjorn’s Corner: SES, Single European Sky
By Bjorn Fehrm
June 10, 2016, ©. Leeham Co: Last week I wrote about the practical implementation of the next generation Air Traffic Management (ATM) that is possible with the new technology based on ADS-B transponders. My examples were from the implementation of the US NextGen Air Traffic Management.
The US has the advantage that the airspace has one Air Navigation Service Provider (ANSP), i.e. one organization for the Air Traffic Controllers. We will now look at the next generation Air Traffic Management in Europe where the project is called SES, Single European Sky. I wrote about SESAR, Single European Sky ATM Research, last week. This is the technology project for implementing ADS-B based ATM, SES is the European Union initiative involving all ANSPs in Europe in the change process.

Presently Europe is divided into 37 ANSPs (the US airspace has one). The ANSPs operate within the national borders of the European states, each serving its own country. SES has proposed to change the present 37 Functional Airspace Blocks (FABs) to 9, Figure 1 Read more
Bjorn’s Corner: Transponders, the kingpin of safe air navigation, Part 3.
By Bjorn Fehrm
June 3, 2016, ©. Leeham Co: Over the past few weeks, we have described how transponders go from being little more capable than the WW2 IFF that they were developed from, to how they will act as information beacons, sending the aircraft’s ID, position and speed to all surrounding listeners every second.
The consequences of this change are nothing short of revolutionary. From a situation where the ground controller or adjacent aircraft had scarce information on the multitude of aircraft they tried to track, Figure 1, they can now receive all the information they need from the aircraft under observation.

This, together with other technologies like data link-based communication, will change Air Traffic Management as we know it.
IATA on air safety
By Bjorn Fehrm in Dublin
Introduction
June 1, 2016, ©. Leeham Co: We report from the International Air Transport Association’s (IATA) Annual General Meeting running in Dublin Thursday and Friday this week, where all the world’s airlines meet to report on a number of initiatives and decide on things to do going forward.
The first briefing from IATA was on the level of safety in the air for 2015, measured through the IATA Operational Safety Audit, IOSA. 2015 was a good year, not quite to the level of 2014 which was the safest year in history, but close at 0.32 jet hull losses per one million flights instead of 0.27 recorded for 2014, Figure 1.
Figure 1. Jet hull losses during 2015 per million flight hours. Source: IATA.
As a reference, the the 2013 rate was 0.41 hull losses over one million flights. The 2015 rate was a 30% improvement over the average rate of the years 2010-2014. The turboprop level was worse at 1.29 hull losses per million flights but it was a large improvement compared to previous years at 3.13 and 3.95. It shall be cautioned that the sample size for Turboprops is much smaller than for Jets, therefore one hull loss will affect the statistics quite a lot. Read more
Dissecting Wide-Body deliveries through 2030
Subscription Required.
Introduction
May 26, 2016, © Leeham Co.: A softening of trans-Atlantic air traffic, with declining yields and passenger demand, raises anew concerns that there is an oversupply and over-ordering of twin-aisle aircraft.
Air Lease Corp. addressed this concern at its May 19 investors day, arguing that growth plus retirements over the next 25 years more than supports the orders.
ALC, which is headed by Steve Udvar-Hazy and John Plueger, considered two of the leaders of the lessor industry, note that there is an average of about 150 wide-bodies approaching 25 years in age each year for the next 20 years. Coupled with long-haul traffic growth, ALC—which has a modest number of wide-body orders—is comfortable with the future supply-demand.
We’ve dissected the known delivery dates of wide-bodies at Airbus and Boeing, using the Ascend data base as of January. Wide-body orders have been announced subsequently, but not all have been firmed up and the total number won’t materially affect the trend lines.

Summary
- We look at announced production rates by 2020 of Airbus and Boeing. We don’t include our own forecasts.
- We look at the defined delivery dates of the A330, A350, A380, 747-8, 777 and 787. These are all models, including ceo/neo and Classic/X.
- We look at factors that indicate a softening of wide-body demand across the Atlantic.
