DEV FROM CLRNC RTE -- ACR HAS A RTE DEV DUE TO A CONFLICT BTWN THE PREDEP CLRNC AND THE PREFERRED DEP ROUTING. THE FLT PLAN RTE WAS NOT FULLY PRINTED OUT SO THAT THE FLC COULD CHK THE INFO.

Narrative

POORLY WRITTEN PDC AT OUR CREW'S AIRLINE CAUSES PROBS. WE WERE ON THE WRONG AIRWAY BECAUSE OF THIS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR IS AN MD-80 FO FOR A MAJOR ACR WHO HAS OFTEN FOUND ROUTING CONFLICTS BTWN THE PDC; THE PREFERRED DEP ROUTING AND THE FLT PLAN RTE. THE FLT OPS MANUAL AT HIS ACR STATES THAT THE PREFERRED DEP ROUTINGS IS TO BE FOLLOWED TO A POINT WHERE THE PDC IS INTERCEPTED. HOWEVER; THERE ARE ROUTINGS WHERE THIS POINT IS NOT CLRLY DELINEATED AND IN SOME CASES MUST BE INTERPRETED AND IN A FEW CASES THE PREFERRED DEP ROUTING AND THE PDC DO NOT CROSS AND THE TRANSITION IS NOT CLR. THIS FO USED THE FULL PRINTOUT OF THE FLT PLAN RTE TO TRY TO ASSIST HIS UNDERSTANDING OF THE RTE; BUT RECENTLY THE COMPANY HAS STARTED TO ABBREVIATE THE FLT PLAN RTE DUE TO SOME COMPUTER SOFTWARE PROB. IN THIS PARTICULAR CASE; THE FO ENTERED THE PREFERRED DEP ROUTING AND PDC INFORMATION IN THE FMC AND THE FULL RTE FLT PLAN RTE WAS NOT PRINTED SO HIS USUAL XCHK WAS NOT AVAILABLE. THE PREFERRED DEP ROUTING CONNECTION TO THE PDC WAS NOT APPARENT TO THE FO SO HE INTERPRETED WHERE THE RTES WOULD TRANSITION AND HE WAS INCORRECT ACCORDING TO THE ARTCC RADAR CTLR WHO THEN PROVIDED VECTORS TO THE PROPER RTE. THERE WAS AN EXTENSIVE DISCUSSION IN THE AIR. LATER THE FO HAD SEVERAL DISCUSSIONS WITH COMPANY MGRS ABOUT THE PROB; BUT THERE HAS BEEN NO CHANGE FOR THE BETTER. MORE RECENTLY; THE RPTR RECEIVED A CONFLICTING PREFERRED DEPT ROUTING AND PDC WHICH HE RESOLVED BY HAVING THE CLRNC DELIVERY CTLR CONTACT THE DEP CTL AND ARTCC TO DETERMINE THE CORRECT TRANSITION. THE FO SAID THAT HE NOW ALSO CHKS WITH THE SECTORS BEYOND THE ABBREVIATED FLT PLAN RTE INFO TO SEE IF THEIR ROUTING AGREES WITH HIS. THIS IS A PONDEROUS TECHNIQUE; AT BEST; AND REQUIRES EXCESSIVE RADIO XMISSIONS.
