PRE DEP CLRNC MISINTERP. RPTR'S COMPANY RECENTLY BECAME USERS OF THE PDC FOR FLCS. THE RPTR FLC DIDN'T UNDERSTAND WHAT THE 'LOOP 9 DAG' ADDITION MEANT AT THE TOP OF THE PDC. THAT INDICATED A REVISION WHICH THEY DIDN'T KNOW. THUS; THEY STARTED THE DEP ON A DIFFERENT SID UNTIL ADVISED BY ATC OF THE CORRECT ROUTING.

Narrative

THE AIRLINE I FLY FOR HAS JUST BEGUN USING PRINTED PDC'S BROUGHT TO THE COCKPIT JUST BEFORE PUSHBACK (SEE ATTACHED). WE WERE DEPARTING LAX WITH THE ENCLOSED PDC. I READ THIS AS LAXX 2 DEP DAG TRANSITION FLT PLANNED RTE. ON DEP WE WERE INITIALLY RESTR TO 2000 FT AND THEN 5000 FT ON A VECTOR. FINALLY WE WERE TOLD TO RESUME THE LOOP 9 DEP; CLB AND MAINTAIN 15000 FT. WE ADVISED ATC THAT WE WERE ON THE LAXX 2. AFTER A FEW MOMENTS HE ADVISED US THAT WE WERE CLRED THE LOOP 9 PER TWR AND COULD WE MAKE THE ALT RESTRS? WE WERE HVY AND ADVISED HIM WE COULD NOT MAKE THE 13000 FT AT 8 DME LAX 041 DEG RADIAL; BUT WE DID MAKE 15000 FT AT 20 DME. ATC ADVISED US IT WOULD NOT BE A PROB; HE WOULD PROVIDE ANY NECESSARY VERT SEPARATION AND THERE WERE NO CONFLICTS. AFTER REVIEWING THE PDC; WE SAW THE LOOP 9 WAS INDICATED; BUT THE LAXX 2 WAS ALSO INDICATED ALONG WITH THE ROUTING. WE FOCUSED ON THE LAXX 2 AND COMPLETELY MISSED THE LOOP 9 ALONG WITH THE EFFECTIVE TIMES OF THE DEPS. TO AVOID CONFUSION; PDC SHOULD ONLY LIST THE CLRED ROUTING.
