Narrative:

Air carrier X, climbing swbound, was in conflict with aircraft Y at 13000 ft (eastbound). When the r-side controller realized the 2 were in conflict, an immediate descent and turn was issued to air carrier X to 11000 ft and heading 270 degrees. A climb and turn was also issued to aircraft Y, climb to FL180 and heading 180 degrees.

Original NASA ASRS Text

Title: ZID ARTCC RADAR CTLR IS UNABLE TO MAINTAIN SEPARATION BTWN CLBING B727 TFC AND A C525 AT 13000 FT.

Narrative: ACR X, CLBING SWBOUND, WAS IN CONFLICT WITH ACFT Y AT 13000 FT (EBOUND). WHEN THE R-SIDE CTLR REALIZED THE 2 WERE IN CONFLICT, AN IMMEDIATE DSCNT AND TURN WAS ISSUED TO ACR X TO 11000 FT AND HDG 270 DEGS. A CLB AND TURN WAS ALSO ISSUED TO ACFT Y, CLB TO FL180 AND HDG 180 DEGS.
