To be fair MJ I have never had an aircraft say to me that they have traffic on TCAS without a prompt.........often though as in this instance we are talking about I have advised an aircraft of possible traffic info and they have responded with yes we can see something on TCAS..........also often I have called traffic and been told yes we are visual............as you are well aware we NEVER asume in ATC so even though they can see something either visual or electronically it may not be the subject aircraft I am giving info on!....
