Reminds of debates about ethics and morality...
I think when the airlines want to have a serious discussion about safety practices, then hiring practices will be first on the agenda, not whether we need TCAS I or II, or third FMS on board.
When all the lights go out, we either have pilots that can dead reckon and hand fly or we do not. Let's start there.
It's laughable to discuss SOPS and safety strategies when the airlines continue to hire personality over experience.
