Barcelona is equipped with radar right? Why clear a four engine heavy with hundreds of people onboard to arrange his own separation from 2 other aircraft? Sounds at best lazy. What would be wrong with proper vectoring in this scenario?
Every time I hear people respond to a traffic report with "we have him on TCAS", I do wonder what they are saying exactly. I don't see the relevance of that statement.
But then I similarly get irritated by "Down 200" and "squawk coming down". Maybe I need a holiday...
