Narrative:
Air carrier X, H/L1011, on ILS runway 31L, advised he was responding to a TCASII RA and climbing. X climbed to 3000 ft. Only other traffic was 3 mi behind, on parallel ILS runway 31R course and not overtaking. TCASII continues to issue needless RA's, especially on final, where proximity of aircraft is closer than that found in the en route environment, but where standard ATC separation is being applied, TCASII may work well away from the airport, but is impractical close to the airport.

Title: MULTIPLE RWY OP PARALLEL RWY APCHS ACR X TCASII RA NON ADHERENCE TO ATC CLRNC EVASIVE ACTION TAKEN FROM Y.
Narrative: ACR X, H/L1011, ON ILS RWY 31L, ADVISED HE WAS RESPONDING TO A TCASII RA AND CLBING. X CLBED TO 3000 FT. ONLY OTHER TFC WAS 3 MI BEHIND, ON PARALLEL ILS RWY 31R COURSE AND NOT OVERTAKING. TCASII CONTINUES TO ISSUE NEEDLESS RA'S, ESPECIALLY ON FINAL, WHERE PROX OF ACFT IS CLOSER THAN THAT FOUND IN THE ENRTE ENVIRONMENT, BUT WHERE STANDARD ATC SEPARATION IS BEING APPLIED, TCASII MAY WORK WELL AWAY FROM THE ARPT, BUT IS IMPRACTICAL CLOSE TO THE ARPT.
