Narrative:

Subject: near miss, use of TCAS, RA with altitude diversion. Level flight 10000 ft at 250 KTS. TCAS very good, but in approach vectoring phase too great a task environment to constantly monitor TCAS when other critical duties, radio calls, fls tuning, checklists, etc, demands are excessive in the time constraints. ATC not helpful, since event occurred, then we advised ATC of our TCAS RA and a plus 800 ft altitude diversion to miss conflicting traffic. Syr approach said he advised us that traffic at 9500 ft. We did not receive same nor did we acknowledge same approach seemed nonchalant since he 'advised' us of traffic, but TCAS indicated - O2 on collision course and TCAS RA taken. It is presumed that traffic may have been assigned 9500 ft, but may have actually been maneuvering vertically. What training does ATC have for controllers concerning TCAS?

Original NASA ASRS Text

Title: TFC GIVEN AT 9500 BUT MLG FLC AT 10000 HAD TCAS RA AND CLIMBED 800 FT.

Narrative: SUBJECT: NEAR MISS, USE OF TCAS, RA WITH ALT DIVERSION. LEVEL FLT 10000 FT AT 250 KTS. TCAS VERY GOOD, BUT IN APCH VECTORING PHASE TOO GREAT A TASK ENVIRONMENT TO CONSTANTLY MONITOR TCAS WHEN OTHER CRITICAL DUTIES, RADIO CALLS, FLS TUNING, CHKLISTS, ETC, DEMANDS ARE EXCESSIVE IN THE TIME CONSTRAINTS. ATC NOT HELPFUL, SINCE EVENT OCCURRED, THEN WE ADVISED ATC OF OUR TCAS RA AND A PLUS 800 FT ALT DIVERSION TO MISS CONFLICTING TFC. SYR APCH SAID HE ADVISED US THAT TFC AT 9500 FT. WE DID NOT RECEIVE SAME NOR DID WE ACKNOWLEDGE SAME APCH SEEMED NONCHALANT SINCE HE 'ADVISED' US OF TFC, BUT TCAS INDICATED - O2 ON COLLISION COURSE AND TCAS RA TAKEN. IT IS PRESUMED THAT TFC MAY HAVE BEEN ASSIGNED 9500 FT, BUT MAY HAVE ACTUALLY BEEN MANEUVERING VERTICALLY. WHAT TRAINING DOES ATC HAVE FOR CTLRS CONCERNING TCAS?
