Narrative:
Approach called traffic initially at 6800' and climbing at 1 O'clock and same direction. We had leveled 8000' and obtained visibility on traffic. He would have cleared our aircraft ok, however TCAS increased from a TA to an RA, to which we were required to respond per TCAS procedure. We initiated a climb and advised ATC. We climbed to 8400' MSL before resuming normal flight at termination of TCAS advisory.

Title: ACR MLG ALT DEVIATION EXCURSION FROM CLRNC ALT IN RESPONSE TO TCAS II RA.
Narrative: APCH CALLED TFC INITIALLY AT 6800' AND CLBING AT 1 O'CLOCK AND SAME DIRECTION. WE HAD LEVELED 8000' AND OBTAINED VIS ON TFC. HE WOULD HAVE CLRED OUR ACFT OK, HOWEVER TCAS INCREASED FROM A TA TO AN RA, TO WHICH WE WERE REQUIRED TO RESPOND PER TCAS PROC. WE INITIATED A CLB AND ADVISED ATC. WE CLBED TO 8400' MSL BEFORE RESUMING NORMAL FLT AT TERMINATION OF TCAS ADVISORY.
