Given the unprofessional comment made by the Dash-8 pilot, it seemed to me
that after calling traffic in sight, both pilots went heads down in
preparation for landing and the TCAS alert shocked them back outside.

Someone with whom I fly occasionally likes to tell ATC of traffic in sight
whenever it's in sight. I'll refrain if, for some reason, I'll be unable
to maintain visual separation (ie. I'm about to lose site of the other
aircraft over the wing).

I don't want to be responsible for visual separation from something I cannot
see.

Technically, of course, I know that this really only applies when we're both
IFR. But I follow this habit all the time anyway.

Problem? Good idea?
