Narrative:

Simultaneous ILS approachs to runway 5 land left&right using new pgm equipment. Air carrier X asked about traffic behind him on final. He was advised that there was a SF34 4 mi intrail. Air carrier X then said he got an RA. Air carrier X was then advised about additional traffic off his right was a company 727 landing runway 5R. Air carrier X took no further action. Once again, the use of TCASII during simultaneous ILS's has alarmed aircraft needlessly and, thankfully, this aircraft didn't take any action to put his aircraft in harm's way.

Title: ACR X TCASII RA WITH ACR Y WHILE ON CLOSE PROX SIMULTANEOUS PARALLEL APCH.

Narrative: SIMULTANEOUS ILS APCHS TO RWY 5 LAND L&R USING NEW PGM EQUIP. ACR X ASKED ABOUT TFC BEHIND HIM ON FINAL. HE WAS ADVISED THAT THERE WAS A SF34 4 MI INTRAIL. ACR X THEN SAID HE GOT AN RA. ACR X WAS THEN ADVISED ABOUT ADDITIONAL TFC OFF HIS R WAS A COMPANY 727 LNDG RWY 5R. ACR X TOOK NO FURTHER ACTION. ONCE AGAIN, THE USE OF TCASII DURING SIMULTANEOUS ILS'S HAS ALARMED ACFT NEEDLESSLY AND, THANKFULLY, THIS ACFT DIDN'T TAKE ANY ACTION TO PUT HIS ACFT IN HARM'S WAY.
