Narrative:

Flight, DC10, dtw-lax on arrival to lax, descending on civet arrival, then cleared to intercept runway 25L localizer to descend to 3500 ft. We were advised to slow to various speeds, which required confign at a distance farther than normal from runway. Were told we were overtaking slower aircraft, but not the type. Radio chatter from and to lax approach was very busy. We continued to overtake the traffic, and was then told to level off at 5000 ft and turn to heading 200 degrees from approximately 270 degrees, then after a while, to turn to heading 340 degrees, about localizer (runway 25L). As needles centered, we were told to intercept runway 25L localizer, which required an almost 90 degree turn, which was too much at that proximity to localizer. No intermediate turns were given. We were then given clearance for the approach once established, and descent was started from 5000 ft, we received a TCASII advisory and was told by approach to climb back to 3500 ft, which we promptly executed, then reclred from inside the FAF to land on runway 25L. No TCASII resolution was given, only advisory. No further directions from approach control, was released to lax tower and landing completed. While on approach, before off course vector we were advised that we should be prepared for a go around due to overtaking speed, relative to aircraft ahead of us.

Title: DC10 CAPT'S RPT ON AN EXHAUSTING APCH INTO LAX WITH NUMEROUS HEADING CHANGES AND ALT ADJUSTMENTS FOR TFC SEPARATION DURING APCH.

Narrative: FLT, DC10, DTW-LAX ON ARR TO LAX, DSNDING ON CIVET ARR, THEN CLRED TO INTERCEPT RWY 25L LOC TO DSND TO 3500 FT. WE WERE ADVISED TO SLOW TO VARIOUS SPDS, WHICH REQUIRED CONFIGN AT A DISTANCE FARTHER THAN NORMAL FROM RWY. WERE TOLD WE WERE OVERTAKING SLOWER ACFT, BUT NOT THE TYPE. RADIO CHATTER FROM AND TO LAX APCH WAS VERY BUSY. WE CONTINUED TO OVERTAKE THE TFC, AND WAS THEN TOLD TO LEVEL OFF AT 5000 FT AND TURN TO HDG 200 DEGS FROM APPROX 270 DEGS, THEN AFTER A WHILE, TO TURN TO HDG 340 DEGS, ABOUT LOC (RWY 25L). AS NEEDLES CTRED, WE WERE TOLD TO INTERCEPT RWY 25L LOC, WHICH REQUIRED AN ALMOST 90 DEG TURN, WHICH WAS TOO MUCH AT THAT PROX TO LOC. NO INTERMEDIATE TURNS WERE GIVEN. WE WERE THEN GIVEN CLRNC FOR THE APCH ONCE ESTABLISHED, AND DSCNT WAS STARTED FROM 5000 FT, WE RECEIVED A TCASII ADVISORY AND WAS TOLD BY APCH TO CLB BACK TO 3500 FT, WHICH WE PROMPTLY EXECUTED, THEN RECLRED FROM INSIDE THE FAF TO LAND ON RWY 25L. NO TCASII RESOLUTION WAS GIVEN, ONLY ADVISORY. NO FURTHER DIRECTIONS FROM APCH CTL, WAS RELEASED TO LAX TWR AND LNDG COMPLETED. WHILE ON APCH, BEFORE OFF COURSE VECTOR WE WERE ADVISED THAT WE SHOULD BE PREPARED FOR A GAR DUE TO OVERTAKING SPD, RELATIVE TO ACFT AHEAD OF US.
