Narrative:

While during intercept to final, runway 28L sfo ILS, we were at 4700 ft approximately 12 mi final. Bay approach turned an MD11 into us. Upon getting a TCASII TA, we spotted the MD11 turning into us at a 90 degree. The TCASII then gave us an RA to 'climb, climb' as to miss the MD11. The approach controller said MD11 missed first 2 calls and then turned him into us on third call. Evasive action was performed by us with a 2000 FPM climb until conflict resolved. Supplemental information from acn 337814: approach gave 3 O'clock MD11 traffic to us. He further stated traffic would remain below us and had us in sight. Maybe all traffic callouts should be confirmed by both pilots as much as possible much like altitude is confirmed.

Original NASA ASRS Text

Title: AN ACR MLG CLBED TO AVOID AN ACR MD11. TCASII COMMANDED THE CLB. THE MLG WAS LINING UP FOR SFO, THE MD11 WAS MANEUVERING FOR SJC.

Narrative: WHILE DURING INTERCEPT TO FINAL, RWY 28L SFO ILS, WE WERE AT 4700 FT APPROX 12 MI FINAL. BAY APCH TURNED AN MD11 INTO US. UPON GETTING A TCASII TA, WE SPOTTED THE MD11 TURNING INTO US AT A 90 DEG. THE TCASII THEN GAVE US AN RA TO 'CLB, CLB' AS TO MISS THE MD11. THE APCH CTLR SAID MD11 MISSED FIRST 2 CALLS AND THEN TURNED HIM INTO US ON THIRD CALL. EVASIVE ACTION WAS PERFORMED BY US WITH A 2000 FPM CLB UNTIL CONFLICT RESOLVED. SUPPLEMENTAL INFO FROM ACN 337814: APCH GAVE 3 O'CLOCK MD11 TFC TO US. HE FURTHER STATED TFC WOULD REMAIN BELOW US AND HAD US IN SIGHT. MAYBE ALL TFC CALLOUTS SHOULD BE CONFIRMED BY BOTH PLTS AS MUCH AS POSSIBLE MUCH LIKE ALT IS CONFIRMED.
