Taking your comments at face value for a minute.
HISLs and Anti Cols on my aircraft don't in any way affect the way I operate. I cannot see them. They enable others to see me.
Thus they don't require me to change my procedures whether they are on or off.
Thus they are all gain when available and no pain in procedure/skills changing.
TCAS, as any pilot knows, is good enough that you start to rely on it. I think that subconsciously you start to trust it and your lookout gets worse. Perhaps not everybody, but certainly me. I am back to flying an aircraft without TCAS at the moment and I have had to really work on getting my lookout back up to speed.
I, like you, firmly believe that safety and airworthiness has an important role to play. The difference is that I don't think that it should rule the roost. Operational effectiveness should be the god we worship, not safety at all costs.
I can tell that my lack of worship of safety and airworthiness dept irks you, but please don't imagine that being referred to as a twenty minuter upsets me for a moment. If only I had the balls.
