Narrative:
During cruise, an avoidance vector was given to us (aircraft X) from ZTL. We did not see the other aircraft Y when TCASII RA instructed a climb. We climbed approximately 500 ft when we acquired the traffic visually and then returned to FL330. Supplemental information from acn 412033: in cruise, on a vector with lots of holding aircraft in the area for atl, we were given an avoidance vector by center.
Original NASA ASRS Text
Title: ACR B737 FLC WAS ISSUED AVOIDANCE RADAR VECTOR FROM ARTCC CTLR AND INITIATED AVOIDANCE TCASII RA CLB FOR CONFLICTING B727 AT SAME ALT.
Narrative: DURING CRUISE, AN AVOIDANCE VECTOR WAS GIVEN TO US (ACFT X) FROM ZTL. WE DID NOT SEE THE OTHER ACFT Y WHEN TCASII RA INSTRUCTED A CLB. WE CLBED APPROX 500 FT WHEN WE ACQUIRED THE TFC VISUALLY AND THEN RETURNED TO FL330. SUPPLEMENTAL INFO FROM ACN 412033: IN CRUISE, ON A VECTOR WITH LOTS OF HOLDING ACFT IN THE AREA FOR ATL, WE WERE GIVEN AN AVOIDANCE VECTOR BY CTR.
