Narrative:

We were on a 230 degree heading for a night visual approach to runway 16R at sea. The runway was changed to runway 16L and traffic was called at 1 O'clock, which was sighted on a downwind west of the airport. We were cleared for a visual approach to runway 16L to keep the traffic in sight that was going to runway 16R. The traffic turned base and joined the final for runway 16R, but was faster than us. Eventually we were flying side-by-side for the south runways. The aircraft was a DC10 and was very close. We received a climb RA as he began to pass, which we complied with. This was followed by a 'monitor vertical speed.' the DC10 was now slightly ahead of us and we could make a normal descent to the runway. Approach control should not issue this type of approach clearance at night with a heavy jet involved. Even though we had the traffic in sight throughout the approach, we did not have information on his speed or when he planned on turning base -- this would help us provide better separation on closely spaced parallel runways. I will not accept approachs like this in the future.

Title: B757 FLC CLB DURING FINAL APCH DUE TO TCASII RA CAUSED BY A DC10 PASSING ALONGSIDE GOING TO THE OTHER PARALLEL RWY. THEY WERE CLRED FOR THE APCH AND INSTRUCTED TO MAINTAIN VISUAL SEPARATION WITH THE DC10.

Narrative: WE WERE ON A 230 DEG HDG FOR A NIGHT VISUAL APCH TO RWY 16R AT SEA. THE RWY WAS CHANGED TO RWY 16L AND TFC WAS CALLED AT 1 O'CLOCK, WHICH WAS SIGHTED ON A DOWNWIND W OF THE ARPT. WE WERE CLRED FOR A VISUAL APCH TO RWY 16L TO KEEP THE TFC IN SIGHT THAT WAS GOING TO RWY 16R. THE TFC TURNED BASE AND JOINED THE FINAL FOR RWY 16R, BUT WAS FASTER THAN US. EVENTUALLY WE WERE FLYING SIDE-BY-SIDE FOR THE S RWYS. THE ACFT WAS A DC10 AND WAS VERY CLOSE. WE RECEIVED A CLB RA AS HE BEGAN TO PASS, WHICH WE COMPLIED WITH. THIS WAS FOLLOWED BY A 'MONITOR VERT SPD.' THE DC10 WAS NOW SLIGHTLY AHEAD OF US AND WE COULD MAKE A NORMAL DSCNT TO THE RWY. APCH CTL SHOULD NOT ISSUE THIS TYPE OF APCH CLRNC AT NIGHT WITH A HVY JET INVOLVED. EVEN THOUGH WE HAD THE TFC IN SIGHT THROUGHOUT THE APCH, WE DID NOT HAVE INFO ON HIS SPD OR WHEN HE PLANNED ON TURNING BASE -- THIS WOULD HELP US PROVIDE BETTER SEPARATION ON CLOSELY SPACED PARALLEL RWYS. I WILL NOT ACCEPT APCHS LIKE THIS IN THE FUTURE.
