Narrative:

The airline I fly for has just begun using printed pre departure clearance's brought to the cockpit just before pushback (see attached). We were departing lax with the enclosed pre departure clearance. I read this as laxx 2 departure dag transition flight planned route. On departure we were initially restr to 2000 ft and then 5000 ft on a vector. Finally we were told to resume the loop 9 departure, climb and maintain 15000 ft. We advised ATC that we were on the laxx 2. After a few moments he advised us that we were cleared the loop 9 per tower and could we make the altitude restrs? We were heavy and advised him we could not make the 13000 ft at 8 DME lax 041 degree radial, but we did make 15000 ft at 20 DME. ATC advised us it would not be a problem, he would provide any necessary vertical separation and there were no conflicts. After reviewing the pre departure clearance, 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 departures. To avoid confusion, pre departure clearance should only list the cleared routing.

Title: 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.
