ACR MLG ALT DEVIATION CROSSING RESTRICTION NOT MET.

Narrative

ENRTE TO LGB WE WERE GIVEN 2 RERTES; EACH ONE ENDING IN PSP DIRECT SLI DIRECT LGB. UPON THE HDOF TO THE LOW ALT CTLR OVER PSP WE WERE TOLD TO CROSS BANDS INTXN (PSP 258 DEGS TO 21 DME) AT 14000 FT. SINCE WE WERE AT FL240; THIS MEANT A HIGH RATE OF DSCNT WAS NECESSARY TO ACCOMPLISH THE XING. TO COMPLICATE MATTERS WE COULD NOT LOCATE BANDS ON THE HIGH ALT CHART (OUR CLRNC WAS DIRECT) AND I HAD TO ASK THE CTLR IT'S LOCATION AND EXPLAIN OUR PREVIOUS CLRNC WAS DIRECT. THE CTLR NOW CLRED US TO LGB VIA 'V372 SLI DIRECT LGB CROSS BANDS AT AND MAINTAIN 14000 FT.' THE CAPT WAS FLYING WHILE I FISHED OUT THE CHART AND FOUND V372; BANDS AND THE DOG LEG VIA HOF. AT THIS POINT THE CAPT HAD FULL SPEED BRAKES AND A BARBER POLE DSCNT; BUT WE STILL MISSED OUR XING BY .5-1 MI. PREVENTION: PLTS CAN ONLY NAV ON THE BASIS OF THEIR ATC CLRNC. IT TAKES TIME TO READ CHARTS; TUNE RADIOS; PLAN DSCNTS; ETC. A LAST MIN CHANGE TO AN ATC CLRNC COUPLED WITH A TIGHT XING RESTRICTION OVERLOADS THE CREW (10000 FT/21 MI). FOR OUR PART; WHEN ATC QUERIED OUR ABILITY TO CROSS BANDS AT 14000 FT I LOOKED AT THE CAPT AND HE NODDED YES. I REPLIED 'WE COULD.' GIVEN THE HIGH RATE OF DSCNT (6000 FPM) WE SHOULD HAVE SAID NO. SUPPLEMENTAL INFO FROM ACN 92863: WE GOT IN TROUBLE BECAUSE THE LOW CTR NEVER GAVE THE HIGH CTR CTLR THE PLANNED RTE OF FLT OR ALT RESTRICTIONS SO WE WERE NOT ABLE TO PLAN AHEAD. WE DON'T FLY INTO LGB OFTEN (MY FIRST TIME) AND THUS WERE NOT FAMILIAR WITH THEIR RESTRICTIONS OR RTES.
