If you think that an airliner in going to spot you just because
you have a transponder, is a very false security.
I fly a Boeing jet for a living and at times it is very hard to see
another jet that ATC and TCAS alerted us to.


But doesn't TCAS gives you resolution without the need to spot the
threat?
I was under the impression that it does.

Only if the threat is also equipped with TCAS...
