B757 FAILS TO FOLLOW PROGRAMMED FMS ROUTE ON CANUK RNAV STAR TO ATL.

Narrative

ON THE CANUK ARR TO ATL. LNAV LINKED TO THE AUTOPLT. APCH CHANGED OUR RWY. I ENTERED THE NEW RWY INTO THE FMS AND NOTED THAT WE WERE STILL ON THE ARR AND THE ADI INDICATOR WE WERE FLYING TOWARD THE ACTIVE WAYPOINT (RIPPI). AT RIPPI; THE ACFT CONTINUED TO FLY STRAIGHT AHEAD INSTEAD OF TURN AND THE FMC DISPLAYED 'FLT PLAN DISCONTINUITY.' I SWITCHED TO HDG SELECT AND AS I WAS DEVIATING FROM THE ARR; ATC CALLED AND GAVE ME VECTORS. THE DATABASE IS NEW IN OUR ACFT AND IS SUPPOSED TO CORRECT PROBS ASSOCIATED WITH RWY CHANGES. I HAVE NOT RECEIVED ANY TRAINING WITH THIS NEW DATABASE. EITHER THE DATABASE DOES NOT MAKE THE CORRECTION; OR I DO NOT KNOW HOW TO USE THE EQUIP PROPERLY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: REPORTER ADVISED THE WAYPOINT AT WHICH THE ANOMALY OCCURRED WAS BOJAA VICE RIPPI AS STATED IN THE NARRATIVE. REPORTER EMPHASIZED THAT AFTER THE NEW RWY WAS EXECUTED THE MAGENTA ACTIVE ROUTE LINE HAD NO DISCONTINUITY DISPLAYED; THE AUTOFLT SYSTEM WAS IN LNAV AND BOJAA WAS MAGENTA; IDENTIFYING IT AS THE ACTIVE WAYPOINT. THE SOP AT THIS ACR ALLOWS THE PF (THE REPORTER) TO PROGRAM THE FMS WHEN THE ACFT IS ON AUTOPLT AND THE PNF IS RESPONSIBLE FOR VERIFYING PROGRAMMING CHANGES PRIOR TO EXECUTION. REPORTER COULD NOT SPECIFICALLY VOUCH THE VERIFICATION WAS ACTUALLY DONE SINCE BOTH PILOTS WERE BUSY DURING THE TERMINAL OPERATION. REPORTER WAS UNAWARE OF OTHER INSTANCES OF THIS ANOMALY.
