Narrative:

IMC at 4000 ft with final approach controller for runway 28L at pit. Heading 070 degrees (angling in toward runway 28L centerline). Air carrier Y was on ILS to runway 28L. TA and RA came close together (within about 7-8 seconds). Controller was busy and did not acknowledge our advisement that we had left our altitude in response to an RA. He sounded unconcerned and gave us a left vector to intercept ILS 28L localizer. Air carrier Y may have had TCASII also.

Title: ACR X TCASII TA RA EVASIVE ACTION TAKEN. NON ADHERENCE TO ATC CLRNC. PLTDEV.

Narrative: IMC AT 4000 FT WITH FINAL APCH CTLR FOR RWY 28L AT PIT. HDG 070 DEGS (ANGLING IN TOWARD RWY 28L CENTERLINE). ACR Y WAS ON ILS TO RWY 28L. TA AND RA CAME CLOSE TOGETHER (WITHIN ABOUT 7-8 SECONDS). CTLR WAS BUSY AND DID NOT ACKNOWLEDGE OUR ADVISEMENT THAT WE HAD LEFT OUR ALT IN RESPONSE TO AN RA. HE SOUNDED UNCONCERNED AND GAVE US A L VECTOR TO INTERCEPT ILS 28L LOC. ACR Y MAY HAVE HAD TCASII ALSO.
