beggars belief
As a PPL I normally only read in this forum, but this is fair game for a comment since it is business / safety and I am well placed to speak on the first and have a vested interest in the latter.
To begin with the quality of the lengthy posting that got this started is poor. For such an "important" assertion it lacks objectivity and has the sound of something that has been lifted from another source.
There is nothing that has been done by TTTech (as reported in the initial posting) that I would have done differently. When you have an emplyee who behaves in this way, you use all legal methods to contain the situation. Equally, the Austrian authorities appear to have conducted themselves properly. That the employee is happy to put himself and his family through this is his look out.
Perhaps a more sensible route would have been to resign from the company, citing his concerns as the reason, copying his letter to Airbus et al.
Two final points. First is that I don't see a cost saving to Airbus from using this chip. I have first hand knowledge of this type of chip and frankly we are talking about small change.
Second, there is nothing to stop this chap seeking employment outside of the aerospace industry.
