CLRNC INTERP RESULTS IN ACR WDB MISSING ALT RESTRICTION ON LAX PROFILE APCH.

Narrative

WERE CLRED FOR A RWY 25L PROFILE DSCNT; THEN ABOUT TNP WERE CLRED TO INTERCEPT RWY 24R APCH. IT PUTS THE PLT FREE AT THAT TIME TO NO LONGER GO BY THE RWY 25L PROFILE DSCNT; WHICH HAS A 14000' AND 18000' AT CIVET. WE CROSSED ABEAM CIVET AT AROUND 12500' AND THE CENTER GOT VERY UPSET. THE CLRNC TO INTERCEPT RWY 24R APCH DOES NOT INCLUDE RWY 25L PROFILE DSCNT. THERE WAS NO CONFLICT OF ANY TFC; ALARMS OR ANYTHING; BUT A LOW ALT AT ABEAM CIVET GOING TO RWY 24R; WHICH IS NOT THE RWY 25L PROFILE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: PIC CALLED CENTER AFTER LNDG AND THEY STATED THEY HAD ABOUT 6 SIMILAR BUSTS AT CIVET THAT DAY. LATER WHEN THEY RETURNED ON ANOTHER TRIP THE CENTER WAS ISSUING THE CLRNC IN A DIFFERENT WAY. RPTR STATED THAT THEY SHOULD ALSO HAVE A PROFILE FOR THE RWY 24 COMPLEX WHICH WOULD HELP DO AWAY WITH CONFUSION. CLAIMS RWY 24 LOC TOO UNSTABLE THAT FAR OUT TO USE FOR NAV. ALSO STATED THAT WHEN CLRNC THOUGHT THEY SHOULD HAVE REQUESTED CLARIFICATION; BUT FREQ WAS SO BUSY DID NOT WANT TO BUST IN.
