Narrative:
At 12000 ft, 250 KTS, we were given a clearance by clt approach to descend to 10000 ft when we got a TCASII RA and thus stopped descent at 11000 ft and advised approach. Then we were given a clearance to maintain 11000 ft. We had a visual on the mdt traffic at all times at the lower altitude.

Narrative: AT 12000 FT, 250 KTS, WE WERE GIVEN A CLRNC BY CLT APCH TO DSND TO 10000 FT WHEN WE GOT A TCASII RA AND THUS STOPPED DSCNT AT 11000 FT AND ADVISED APCH. THEN WE WERE GIVEN A CLRNC TO MAINTAIN 11000 FT. WE HAD A VISUAL ON THE MDT TFC AT ALL TIMES AT THE LOWER ALT.
