APCH CTLR ASKS FLC ABOUT THEIR CLRNC INTERP WHEN ASSIGNED THE EAST SIDE STAR 'WITH ALT RESTRS.'

Narrative

ATC FACILITY; SOCAL APCH LOCATION; BANDS INTXN. RPT FILED DUE TO POSSIBLE MISCOM AND INTERP OF ARR CLRNC. SOCAL CTLR CLRED US FOR EAST SIDE 1 ARR WITH ALT RESTRS AFTER PASSING BANDS INTXN. THAT WAS OUR ONLY CLRNC. WE STARTED OUR DSCNT SO AS TO CROSS KAYOH AT 8000 FT; 210 KTS. AFTER WE STARTED THE DSCNT THE CTLR SAID THE CLRNC WAS A LITTLE CONFUSING AND WANTED TO KNOW OUR INTERP OF IT. WE TOLD HIM WE WOULD CROSS KAYOH AT 8000 FT; 210 KTS AND F047 AT OR ABOVE 7000 FT. HE SAID HE WANTED KAYOH AT 8000 FT. WE FAILED TO NOTICE THE NOTE TO MAINTAIN LAST ASSIGNED ALT TO KAYOH. NO CONFLICT OR TCASII ALERT; WE WERE IN THE CLR WITH VISIBILITY AT LEAST 5 MI. EVEN WITH THE CHART OUT; THE NOTE WAS NOT ANNOTATED ON THE FMC. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE CAPT WAS FLYING AND WAS ANXIOUS TO GET DOWN SINCE HE WAS FAIRLY NEW ON THE ACFT TYPE. THE CREW HAD REVIEWED THE STAR CHART AND KNEW THAT THE ALT DEPICTED FOR XING KAYOH (8000 FT; 210 KTS) WAS AN 'EXPECTED' ALT. THE FLT WAS ARRIVING OVER PSP VOR AND HAD BEEN ASSIGNED TO CROSS 'BANDS' INTXN AT 14000 FT. THEN THE EAST SIDE ARR STAR CLRNC WAS ISSUED. AFTER BANDS THE ACFT WAS IN DSCNT. AT ABOUT 11500 FT THE CTLR INTERVENED WITH HIS QUESTION REGARDING THE CLRNC INTERP. THE CTLR SAID THAT THE INTERP WAS CORRECT; THAT HE HAD WANTED THE FLT AT KAYOH AT 8000 FT BUT WAS WONDERING HOW THE CREW INTERPRETED HIS CLRNC. THE RPTR WAS CONFUSED AS TO WHY THE CTLR ISSUED THE CLRNC IN THAT MANNER IF THE STAR CHART NOTE SAID TO 'MAINTAIN THE LAST ASSIGNED ALT TO KAYOH.' THE ACFT WOULD HAVE HAD A SEVERE ALT PROB WITH XING KAYOH AT 14000 FT AS THAT INTXN IS ONLY 12.9 NM FROM THE LOM FOR RWY 19R AT SNA. EVEN XING KAYOH AT 8000 FT IS A CHALLENGE AND A 'SLAM DUNK' APCH DUE TO THE HILLS AND SOUND ABATEMENT POLICY AT SNA. THE FMC DID NOT HAVE ANY NOTES REGARDING ANY RESTRS; ONLY A 'KAYOH AT OR ABOVE 7000 FT' FOR BEST FUEL ECONOMY. RPTR WOULD LIKE THE NOTE MOVED TO A SECTION NEARER THE BANDS/KAYOH LEG AND ATC TO NOT CONFUSE THE ISSUE WITH CLRNCS PHRASED AS THIS ONE WAS. THE KEEP THEM HIGH PROC (IE; 14000 FT) IS VERY DIFFICULT TO DEAL WITH.
