Narrative:
Air carrier X on final for runway 27L approximately 3-4 mi east had been issued VFR helicopter traffic and altitude (1200 ft). Air carrier X reported TCASII RA and informed us that he was climbing. Controller responded that once again air carrier X had helicopter traffic (both controller and helicopter had visual separation). Controller instructed air carrier X to execute missed approach because aircraft was now too high to execute the approach. I do not agree with pilots responding to RA's inside the OM when traffic has been issued by the controller and proper separation exists. This is disruptive and expensive to airlines.
Original NASA ASRS Text
Title: ACR X TCASII RA FROM VFR HELI VISUAL SEPARATION IN USE EVASIVE ACTION CLB CTLR ISSUED MISSED APCH.
Narrative: ACR X ON FINAL FOR RWY 27L APPROX 3-4 MI E HAD BEEN ISSUED VFR HELI TFC AND ALT (1200 FT). ACR X RPTED TCASII RA AND INFORMED US THAT HE WAS CLBING. CTLR RESPONDED THAT ONCE AGAIN ACR X HAD HELI TFC (BOTH CTLR AND HELI HAD VISUAL SEPARATION). CTLR INSTRUCTED ACR X TO EXECUTE MISSED APCH BECAUSE ACFT WAS NOW TOO HIGH TO EXECUTE THE APCH. I DO NOT AGREE WITH PLTS RESPONDING TO RA'S INSIDE THE OM WHEN TFC HAS BEEN ISSUED BY THE CTLR AND PROPER SEPARATION EXISTS. THIS IS DISRUPTIVE AND EXPENSIVE TO AIRLINES.
