Narrative:

On the arrival phase into atl coming from the west, we were given a runway change. The captain was loading it in the FMS when this was done. The first officer began retrieving the new approach plate and reviewing it. At this time, approach control gave us a descending turn. The first officer began the descent, but not the turn. The captain prompted the turn and the first officer responded. However, the turn came late and a TA followed by a climbing RA was received. ATC was advised of the maneuver as we were complying. A 'clear of conflict' was soon received and the flight continued without further incidence.

Title: CL65 FO, SLOW TO RESPOND TO VECTOR HDG CHANGE BY A80, INITIATES TCASII RA MANEUVER DUE TO CONFLICTING TFC.

Narrative: ON THE ARR PHASE INTO ATL COMING FROM THE W, WE WERE GIVEN A RWY CHANGE. THE CAPT WAS LOADING IT IN THE FMS WHEN THIS WAS DONE. THE FO BEGAN RETRIEVING THE NEW APCH PLATE AND REVIEWING IT. AT THIS TIME, APCH CTL GAVE US A DSNDING TURN. THE FO BEGAN THE DSCNT, BUT NOT THE TURN. THE CAPT PROMPTED THE TURN AND THE FO RESPONDED. HOWEVER, THE TURN CAME LATE AND A TA FOLLOWED BY A CLBING RA WAS RECEIVED. ATC WAS ADVISED OF THE MANEUVER AS WE WERE COMPLYING. A 'CLR OF CONFLICT' WAS SOON RECEIVED AND THE FLT CONTINUED WITHOUT FURTHER INCIDENCE.
