Odds and Ends: Real-time flight tracking; LEAP-1A testing
Real-time flight tracking: At last, the airline industry is adopting rules to require real-time flight tracking. ICAO, the international organization governing rules and regulations, approved one to require real time tracking next year. The action is long overdue.
Singapore Airlines has made the decision to begin installing the system sooner.
Initially data will be transmitted at 15 minute intervals but if a flight anomaly occurs, transmissions will occur at one minute intervals. While the system won’t prevent real-time accidents (or hijackings), locating airplanes sooner could save lives if an accident is survivable or accelerate recovery of flight data recorders and cockpit voice recorders to solve an accident sooner and potentially prevent accidents in the future from the results.
LEAP-1A testing: The CFM LEAP-1A, destined for the Airbus A320neo family, is now in flight testing, reports Flight Global.
Muilenburg’s challenges as Boeing CEO

Now open to all readers
Introduction
Jan. 27, 2015: Dennis Muilenburg has been the No. 2 at The Boeing Co. for a little more than a year. He was named vice chairman, president and COO in December 2013.
Jim McNerney
His boss, Chairman and CEO Jim McNerney, turned 65 last August. Sixty-five is the mandatory retirement age, but this has been waived before and McNerney is widely understood to want to stick around through Boeing’s 100th Anniversary in 2016.
The industry is buzzing with reports that McNerney might move up soon to
Dennis Muilenburg
non-executive chairman, with Muilenburg assuming the CEO title.
If and when Muilenburg becomes CEO, he faces a laundry list of challenges.
Summary
- Strong competition from Airbus that is getting stronger;
- Continued cost cutting;
- Learning the Commercial Airplanes business;
- Declining defense business and revenues, putting pressure on profits and cash flow;
- Flight testing and development of the KC-46A;
- Development of the 737 MAX and 777X and proving that delivering new airplane programs on time and on budget can be achieved again;
- Selling enough 777 Classics to maintain production rates to the 2020 EIS of the 777X;
- Dealing with labor unrest with its Seattle area unions and a new attempt to organize the Charleston 787 plant; and
- Deciding whether to take that “moonshot” and launch new airplanes earlier than the 2030 EIS McNerney set as policy.
Fundamentals of airliner performance, Part 6; The engine
By Bjorn Fehrm
19 Jan 2015: There is a lot written about the fundamentals of how aircraft fly. It is something that fascinates people and it generates a high level of understanding of these fundamentals. The same is not true for the airline turbofan engines in use today; their detailed function remains a bit of black art.
To some extent this might be because what is exiting in the engines (the thrust) is generated behind closed doors. The only visible part of the process is a rotating fan face and sometimes a slight miss-colored exhaust out the other way. There is also at takeoff a funny buzzing sound interspersed with the general engine noise. Apart from that, the most that one sees is a round nacelle and that is it.
A380neo decision likely this year, triggering the next widebody engine project

Introduction
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.
Summary
- A380 Classic equals Boeing 777-300ER seat fuel costs.
- Boeing 777-9 beats A380 on CASM, an A380neo regains the advantage.
- Engine makers face hard choices to retain dominance or to broaden market penetration.
Airbus/Boeing duopoly single-aisle is safe well into 2030 decade

Introduction
Dec. 28, 2014: Two challenges to the duopoly of Airbus and Boeing in the 150-220 seat single-aisle sector move forward in development in 2015, but neither is in a position to be a threat for the balance of this decade, nor even in the next.
Both challenges, the COMAC C919 from China, and the Irkut MC-21 from Russia, will for various reasons fall short of the Airbus A320/321 and Boeing 737-8/9 and plans to design the next generation new single-aisle airplane.
Summary
- The C919’s chief advantage was eliminated when Airbus and Boeing moved to reengine the A320 and 737 families.
- C919 retains pricing advantage but won’t overcome duopoly dominance.
- By the time the C919 enters service, Airbus and Boeing will have the second generation of LEAP and GTF engines available.
- The MC-21 takes into account better passenger comfort through a wider fuselage, but engines will be no better than those used on Airbus and Boeing.
- The MC-21 sales potential will be highly limited because Russia still hasn’t become a full trading partner due to political direction.
AirAsia A320 disappears en route in bad weather, but weather won’t be only area of investigative focus
Dec. 28, 2014: Weather will be a prime area of focus by investigators of the disappearance of AirAsia flight QZ8501. The flight, an Airbus A320-200 manufactured in 2008 and powered by CFM 56 engines, deviated from its intended flight path due to weather conditions, according to reports from officials in Indonesia.
It’s presumed the airplane’s disappearance is an accident.
With these reports, investigators will put weather conditions at the top of their list of areas to probe. They will attempt to determine whether there was a high altitude upset due to turbulence that caused the plane to lose control; whether the plane was intact when it presumably crashed into the sea or whether it came apart in flight, and if so whether this possibility was caused by stresses beyond design limits. Investigators will attempt to determine whether the plane was struck by lightning, causing a chain of events leading to a crash.
