Narrative:

At 17000 ft on a 080 degree heading (approximately location atlantic city VOR radial 267 at 56 DME) VMC conditions. Captain was pilot flying. ATC asked if we had traffic at 3 O'clock; 4000 ft below. First officer had visual and stated so to ATC. Captain did not have visual; but acknowledged position of TCAS target. ATC cleared us direct acy at 17000 ft and cleared other traffic direct woodstown (ood) with a climb to 23000 ft. Both aircraft acknowledged visual contact. We anticipated a TA which occurred; however it was quickly followed by a resolution advisory requiring a climb of 2500 FPM. I initiated a climb and the first officer notified ATC. Conflicting traffic continued climb until we received a descending RA. On receiving this; we returned to our assigned altitude of 17000 ft; which cleared the RA. Total deviation was 17600 ft prior to return to assigned altitude.

Title: CL65 FLT CREW EXPERIENCED TCAS RA AFTER ATC INSTRUCTED CLBING TFC TO MAINTAIN VISUAL SEPARATION FROM THE CL65 IN LEVEL FLT.

Narrative: AT 17000 FT ON A 080 DEG HDG (APPROX LOCATION ATLANTIC CITY VOR RADIAL 267 AT 56 DME) VMC CONDITIONS. CAPT WAS PLT FLYING. ATC ASKED IF WE HAD TFC AT 3 O'CLOCK; 4000 FT BELOW. FO HAD VISUAL AND STATED SO TO ATC. CAPT DID NOT HAVE VISUAL; BUT ACKNOWLEDGED POSITION OF TCAS TARGET. ATC CLRED US DIRECT ACY AT 17000 FT AND CLRED OTHER TFC DIRECT WOODSTOWN (OOD) WITH A CLB TO 23000 FT. BOTH ACFT ACKNOWLEDGED VISUAL CONTACT. WE ANTICIPATED A TA WHICH OCCURRED; HOWEVER IT WAS QUICKLY FOLLOWED BY A RESOLUTION ADVISORY REQUIRING A CLB OF 2500 FPM. I INITIATED A CLB AND THE FO NOTIFIED ATC. CONFLICTING TFC CONTINUED CLB UNTIL WE RECEIVED A DSNDING RA. ON RECEIVING THIS; WE RETURNED TO OUR ASSIGNED ALT OF 17000 FT; WHICH CLRED THE RA. TOTAL DEV WAS 17600 FT PRIOR TO RETURN TO ASSIGNED ALT.
