Obviously doesn't pay to be a whistleblower in the new Europe either- you still end up dismissed, in court, paying out tens of thousands and being counter-sued, even though you are demonstrably correct in your contentions. Don't depend upon any justice in an Austrian Court either. They all pay homage to the almighty Airbus.
There is no latitude in DO-178(B) for any "proven by use in other non-aviation applications" contexts. TTTech and Nord Micro were just trying to make a fast buck by slipping one through. They also worked on the A340 and the Embraer ERJ-170 systems. They probably also did the software with the near fatal flaw in the A340-500/600 fuel system transfer.
You have to wonder what other shonks they've signed off on.
