I have heard similar explanations, but if there is an aircraft on final, and I'm at holding point, I don't know if there is any difference for the other one wheather I'm sqwaking TA only or TARA. He is only working
his own settings and my altitude is showing anyway.
What puzzles me is really that I can't see any difference for me what I sqwak on ground (because RA is inhibited), nor the other airborne traffic (because they are working their own settings and can't see if I'm sqwaking TA or TARA).
