Narrative:

Our fpr was atl-notwo-J91-vxv-bkw-psb-J59-syr. Our pre departure clearance (ie, initial clearance) was atl-notwo J91 vxv...'fpr.' shortly after leveling off at FL330, we were navigating J91 after passing the vxv VOR (ie, tracking the 030 degree radial instead of our cleared routing of vxv-bkw, which is the 052 degree radial from the vxv VOR). At approximately 30 DME tracking outbound on the 030 degree radial, ZTL queried us of our position, and whether or not we were flying our assigned clearance, which was to track outbound on the vxv 052 degree radial until receiving bkw VOR and proceeding direct. We realized, after being queried, that we indeed were navigating on the wrong course. ZTL reclred us to the bkw VOR. It was my ultimate responsibility to back up the captain as he naved and I did not do that. He verbally stated the course of 030 degrees, and I did not verify the routing. CRM plays a large role avoiding these types of mistakes, each crew member must always back up each other on altitudes, headings, airspds, and clrncs. Supplemental information from acn 504000: ZTL advised us we were off course to the north and heading further off course. We realized our mistake and accepted the controller's heading to bkw. Although I announced the course outbound as 030 degrees, the first officer did not catch the mistake. We discussed the importance of actually checking the map instead of merely verbalizing what you hear. Extra caution must be taken when transitioning between maps (ie, vxv was on H5/H6 while bkw was on H4/H5).

Title: A B727-200 FLC DEVIATES FROM THEIR FILED FLT PLAN, PROCEEDING JET AIRWAY J91 VERSUS DIRECT TO BKW, WV.

Narrative: OUR FPR WAS ATL-NOTWO-J91-VXV-BKW-PSB-J59-SYR. OUR PDC (IE, INITIAL CLRNC) WAS ATL-NOTWO J91 VXV...'FPR.' SHORTLY AFTER LEVELING OFF AT FL330, WE WERE NAVING J91 AFTER PASSING THE VXV VOR (IE, TRACKING THE 030 DEG RADIAL INSTEAD OF OUR CLRED ROUTING OF VXV-BKW, WHICH IS THE 052 DEG RADIAL FROM THE VXV VOR). AT APPROX 30 DME TRACKING OUTBOUND ON THE 030 DEG RADIAL, ZTL QUERIED US OF OUR POS, AND WHETHER OR NOT WE WERE FLYING OUR ASSIGNED CLRNC, WHICH WAS TO TRACK OUTBOUND ON THE VXV 052 DEG RADIAL UNTIL RECEIVING BKW VOR AND PROCEEDING DIRECT. WE REALIZED, AFTER BEING QUERIED, THAT WE INDEED WERE NAVING ON THE WRONG COURSE. ZTL RECLRED US TO THE BKW VOR. IT WAS MY ULTIMATE RESPONSIBILITY TO BACK UP THE CAPT AS HE NAVED AND I DID NOT DO THAT. HE VERBALLY STATED THE COURSE OF 030 DEGS, AND I DID NOT VERIFY THE ROUTING. CRM PLAYS A LARGE ROLE AVOIDING THESE TYPES OF MISTAKES, EACH CREW MEMBER MUST ALWAYS BACK UP EACH OTHER ON ALTS, HDGS, AIRSPDS, AND CLRNCS. SUPPLEMENTAL INFO FROM ACN 504000: ZTL ADVISED US WE WERE OFF COURSE TO THE N AND HDG FURTHER OFF COURSE. WE REALIZED OUR MISTAKE AND ACCEPTED THE CTLR'S HDG TO BKW. ALTHOUGH I ANNOUNCED THE COURSE OUTBOUND AS 030 DEGS, THE FO DID NOT CATCH THE MISTAKE. WE DISCUSSED THE IMPORTANCE OF ACTUALLY CHKING THE MAP INSTEAD OF MERELY VERBALIZING WHAT YOU HEAR. EXTRA CAUTION MUST BE TAKEN WHEN TRANSITIONING BTWN MAPS (IE, VXV WAS ON H5/H6 WHILE BKW WAS ON H4/H5).
