“Increased software-controlled automation of operator tasks has increased operator training workload to merely understand all modes of normal operation. Additionally, off-normal failure modes have increased. To truly comprehend one instrument indication, the operator must understand all ways that indication can occur; otherwise, the operator cannot troubleshoot failure in time to intervene effectively. Complex systems test the real-time limits of diagnostic skill when failure indications proliferate. What is real and what is a false indication? Is there a common thread between multiple different warnings? Does the procedure actually address how the system is behaving? Which option will improve the situation right now? These are questions the expert operator expects to answer in seconds when time-critical failures occur. Only when design and training respect the day-to-day limits of human comprehension and team performance can reliable operation continue.”
The Germanwings Airbus accident investigation should have been done by an international entity with no vested interests in Airbus. It is partially owned by the French State and a major employer.
63,000 European jobs at stake:
“Airbus SAS … is an aircraft manufacturing division of Airbus Group (formerly European Aeronautic Defence and Space Company). It is based in Blagnac, France, a suburb of Toulouse, with production and manufacturing facilities mainly in France, Germany, Spain and the United Kingdom.
Airbus employs around 63,000 people at sixteen sites in four countries: France, Germany, Spain and the United Kingdom. Final assembly production is based at Toulouse, France; Hamburg, Germany; Seville, Spain; and, since 2009 as a joint-venture, Tianjin, China. Airbus has subsidiaries in the United States, Japan, China and India.
The company produces and markets the first commercially viable fly-by-wire airliner, the Airbus A320, and the world’s largest passenger airliner, the A380.” http://en.wikipedia.org/wiki/Airbus The one which went down is an ancient A320, known to have many potential problems which need addressing (as elaborated in our post about the Airworthiness Directives). Plus, the French prosecutor is in Marseille, well-known for its history of corruption (the city that is).
Who owns Airbus?
État français (French State): 11,00 %
État allemand (German State): 10,90 %
BlackRock: 4,20 %
État espagnol (Spanish State): 4,10 %
Clearly the French State should not be doing the investigation of the recently downed Germanwings Airbus A320!
