From ATSIN 49.....
(A/c identity) avoiding action, climb/descend immediately to (level) traffic at (number) o’clock (distance) miles opposite direction/crossing left to right/right to left (level information).
So, let me get this straight. This so-called "Working Group" has decided that an additional "a/c identity" spoken after the "avoiding action" is SO UNTHINKABLY DANGEROUS that the phraseology simply HAD to be changed. But they're perfectly happy for ATCOs to use the instruction above, even though it was a contributory factor in a recent major accident.
If this "Working Group" actually did any "work" they would advise ATCOs to give avoiding action in the horizontal plane only, and allow TCAS to do the rest.
But hey, the ATSIN only remains in force until December this year. Maybe then we'll see some progress.
