Narrative:

While approaching rochester in IMC, issued descent to 5000 ft. Approach issued TA to us of an md-80 which was descending to 4000 ft. Just as we leveled at 5000 ft we got a TA on TCASII. It rapidly went to an RA. I had the md-80 in sight. I illuminated our landing lights. It was clear that the md-80 would pass in front of us. We did not respond to the RA because we had the traffic in sight. Required ATC separation was lost because the approach controller did not watch he descent rate of the md-80. This could have been avoided if the controller realized that the md-80 could not descend at normal rates due to anti-icing requirements. Controller education and training is needed.

Title: TCASII RA FOR 2 MLG ACFT, NO EVASIVE ACTION AS TFC IN SIGHT.

Narrative: WHILE APCHING ROCHESTER IN IMC, ISSUED DSCNT TO 5000 FT. APCH ISSUED TA TO US OF AN MD-80 WHICH WAS DSNDING TO 4000 FT. JUST AS WE LEVELED AT 5000 FT WE GOT A TA ON TCASII. IT RAPIDLY WENT TO AN RA. I HAD THE MD-80 IN SIGHT. I ILLUMINATED OUR LNDG LIGHTS. IT WAS CLR THAT THE MD-80 WOULD PASS IN FRONT OF US. WE DID NOT RESPOND TO THE RA BECAUSE WE HAD THE TFC IN SIGHT. REQUIRED ATC SEPARATION WAS LOST BECAUSE THE APCH CTLR DID NOT WATCH HE DSCNT RATE OF THE MD-80. THIS COULD HAVE BEEN AVOIDED IF THE CTLR REALIZED THAT THE MD-80 COULD NOT DSND AT NORMAL RATES DUE TO ANTI-ICING REQUIREMENTS. CTLR EDUCATION AND TRAINING IS NEEDED.
