Narrative:
Lax arrival conflicts. While flying the pdz 2 arrival to lax, we were told to maintain visual separation with an air carrier B737. We were also assigned 320 KTS. Our turn onto the lax ILS radial put us too close to the B737, which was flying an approach to the runways 24. We fly the assigned arrival, but I feel that we should have been given an altitude separation by approach control. The 2 arrs coincide, almost. We received an RA to descend and did so. I feel that the civet and paradise arrs need to be staggered more. We really needed the visual ability in this case, or might have had a real problem.

Narrative: LAX ARR CONFLICTS. WHILE FLYING THE PDZ 2 ARR TO LAX, WE WERE TOLD TO MAINTAIN VISUAL SEPARATION WITH AN ACR B737. WE WERE ALSO ASSIGNED 320 KTS. OUR TURN ONTO THE LAX ILS RADIAL PUT US TOO CLOSE TO THE B737, WHICH WAS FLYING AN APCH TO THE RWYS 24. WE FLY THE ASSIGNED ARR, BUT I FEEL THAT WE SHOULD HAVE BEEN GIVEN AN ALT SEPARATION BY APCH CTL. THE 2 ARRS COINCIDE, ALMOST. WE RECEIVED AN RA TO DSND AND DID SO. I FEEL THAT THE CIVET AND PARADISE ARRS NEED TO BE STAGGERED MORE. WE REALLY NEEDED THE VISUAL ABILITY IN THIS CASE, OR MIGHT HAVE HAD A REAL PROB.
