Narrative:
On arrival to dtw at 11000 ft MSL, heading of 030 degrees, approach controller advised us of traffic (VFR) at 10500 ft MSL at our 2 O'clock position. We did not acquire the traffic visually and received a 'climb' advisory from TCASII. We followed the advisory and visual sighting on the traffic during our climb. We climbed approximately 700-800 ft before correcting back to our assigned altitude. As we started our climb, my captain advised the controller that we were climbing in response to a RA from TCASII. The controller did not respond -- busy with other traffic.

Title: AN MLG ACR CLBED IN RESPONSE TO A TCASII ALERT ON THE ARR RTE TO DTW.
Narrative: ON ARR TO DTW AT 11000 FT MSL, HDG OF 030 DEGS, APCH CTLR ADVISED US OF TFC (VFR) AT 10500 FT MSL AT OUR 2 O'CLOCK POS. WE DID NOT ACQUIRE THE TFC VISUALLY AND RECEIVED A 'CLB' ADVISORY FROM TCASII. WE FOLLOWED THE ADVISORY AND VISUAL SIGHTING ON THE TFC DURING OUR CLB. WE CLBED APPROX 700-800 FT BEFORE CORRECTING BACK TO OUR ASSIGNED ALT. AS WE STARTED OUR CLB, MY CAPT ADVISED THE CTLR THAT WE WERE CLBING IN RESPONSE TO A RA FROM TCASII. THE CTLR DID NOT RESPOND -- BUSY WITH OTHER TFC.
