Air carrier medium large transport received a TCASII RA on an aircraft on visual approach to parallel runway and behind him. These type RA's create a problem for approach controllers.

Narrative:
Air carrier dc-9 received a TCASII RA to descend while on final at approximately 1200 ft AGL. The RA was generated by air carrier bae-31 following the dc-9 on a visual approach to a parallel runway whose ctrlines are separated by approximately 435 ft. This is a standard arrival procedure for cle. Controller's only course of action is to 'go around' (go up) when TCASII RA instructs to descend. The aircraft experiencing the RA could not visually acquire the intruder aircraft.

Title: ACR MLG RECEIVED A TCASII RA ON AN ACFT ON VISUAL APCH TO PARALLEL RWY AND BEHIND HIM. THESE TYPE RA'S CREATE A PROB FOR APCH CTLRS.
Narrative: ACR DC-9 RECEIVED A TCASII RA TO DSND WHILE ON FINAL AT APPROX 1200 FT AGL. THE RA WAS GENERATED BY ACR BAE-31 FOLLOWING THE DC-9 ON A VISUAL APCH TO A PARALLEL RWY WHOSE CTRLINES ARE SEPARATED BY APPROX 435 FT. THIS IS A STANDARD ARR PROC FOR CLE. CTLR'S ONLY COURSE OF ACTION IS TO 'GAR' (GO UP) WHEN TCASII RA INSTRUCTS TO DSND. THE ACFT EXPERIENCING THE RA COULD NOT VISUALLY ACQUIRE THE INTRUDER ACFT.
