Narrative:

Was reclred approximately 1 hour out of pdx by vancouver center at dolff, btg/312 degrees/70 DME, then the btg/275 degrees/25 DME, then btg, pdx. When the clearance was given captain was in the left seat and international relief officer in the right seat, first officer was on beak and out of the cockpit. Captain made the FMS entries. When ZSE noted the error first officer was in the right seat and hand flying the aircraft while captain made FMS entries. Prior to the btg/312 degrees/70 DME we were given an immediate turn away from restr airspace. ZSE informed us that we were not going to the btg/312 degrees/70 DME waypoint. The FMS showed the waypoint west of our position. They suggested we check our navigation data. A check was made finding 2 btg reference points in the database, both gave the same latitude/longitude, the second also had 116.6. When I was given the clearance, I selected the first waypoint as the latitude/longitude matched the requirement. In my subsequent investigation I found that the btg I selected was actually the btg/275 degrees/25 DME and all waypoints made from btg -- were off this displaced waypoint, ie, btg/275 degrees/25 DME was in fact btg/275 degrees/50 DME, thus the error in navigation. I questioned the crew and no one remembered making a defined waypoint as btg and the radial 275 degrees/25 DME in the defined waypoint page. The database was changed prior to our departure as the last date expired and a new database was used for this flight. Conclusion: when a defined waypoint is made in the FMS, I feel that it should be noted on the flight plan in the event that the pilot is not on duty at the time this waypoint would be referred.

Title: FATIGUED INTL CREW RETURNING FROM JAPAN PROGRAMMED FMS INCORRECTLY WHEN RECEIVING ARR CLRNC. ARTCC OBSERVED RESULTING ENCROACHMENT ON MIL AIRSPACE AND GAVE CORRECTING VECTORS.

Narrative: WAS RECLRED APPROX 1 HR OUT OF PDX BY VANCOUVER CTR AT DOLFF, BTG/312 DEGS/70 DME, THEN THE BTG/275 DEGS/25 DME, THEN BTG, PDX. WHEN THE CLRNC WAS GIVEN CAPT WAS IN THE L SEAT AND IRO IN THE R SEAT, FO WAS ON BEAK AND OUT OF THE COCKPIT. CAPT MADE THE FMS ENTRIES. WHEN ZSE NOTED THE ERROR FO WAS IN THE R SEAT AND HAND FLYING THE ACFT WHILE CAPT MADE FMS ENTRIES. PRIOR TO THE BTG/312 DEGS/70 DME WE WERE GIVEN AN IMMEDIATE TURN AWAY FROM RESTR AIRSPACE. ZSE INFORMED US THAT WE WERE NOT GOING TO THE BTG/312 DEGS/70 DME WAYPOINT. THE FMS SHOWED THE WAYPOINT W OF OUR POS. THEY SUGGESTED WE CHK OUR NAV DATA. A CHK WAS MADE FINDING 2 BTG REF POINTS IN THE DATABASE, BOTH GAVE THE SAME LATITUDE/LONGITUDE, THE SECOND ALSO HAD 116.6. WHEN I WAS GIVEN THE CLRNC, I SELECTED THE FIRST WAYPOINT AS THE LATITUDE/LONGITUDE MATCHED THE REQUIREMENT. IN MY SUBSEQUENT INVESTIGATION I FOUND THAT THE BTG I SELECTED WAS ACTUALLY THE BTG/275 DEGS/25 DME AND ALL WAYPOINTS MADE FROM BTG -- WERE OFF THIS DISPLACED WAYPOINT, IE, BTG/275 DEGS/25 DME WAS IN FACT BTG/275 DEGS/50 DME, THUS THE ERROR IN NAV. I QUESTIONED THE CREW AND NO ONE REMEMBERED MAKING A DEFINED WAYPOINT AS BTG AND THE RADIAL 275 DEGS/25 DME IN THE DEFINED WAYPOINT PAGE. THE DATABASE WAS CHANGED PRIOR TO OUR DEP AS THE LAST DATE EXPIRED AND A NEW DATABASE WAS USED FOR THIS FLT. CONCLUSION: WHEN A DEFINED WAYPOINT IS MADE IN THE FMS, I FEEL THAT IT SHOULD BE NOTED ON THE FLT PLAN IN THE EVENT THAT THE PLT IS NOT ON DUTY AT THE TIME THIS WAYPOINT WOULD BE REFERRED.
