Courtney Mil,
You didn't misunderstand me. After a former Air France Captain and Airbus fan compared the "installation" error to another classical Crew action (French radio) I wanted to have confirmation or corrected information that the misinstallation was/wasn't a Crew action. Therefore my post could seem a bit provocative. You brought the answer, thank you. It means Crew have been victims of IT world.
As a retired IT guy and Airline pilot I'm preaching since 1988 that IT testing has other rules than aircrafts' certification There is a lack in our FBW planes resulting of a sad confusion well pointed in the Ariane501 report. That is first an Ocean of vanity and lack of modesty not only the money competition.
