An MD11 makes an approach into subic bay, philippines, and programs the FMS in error. The flight crew assumes that the aircraft will follow an outbound radial, however the navigation system will not do that and they fly off course. Approach controller gets them back on course.

Narrative:

The problem arose due to confusion between FMS and hard VOR information received. The captain and first officer are new in aircraft type neither one ever having flown the MD11. The problem was discovered when the first officer questioned the (to) point on FMS information. Aircraft was not navigating to the VOR and outbound on the outbound radial as programmed (or thought to be). Approach questioned what we were doing on the wrong radial when we simultaneously figured out where we were. Corrected our flight path and the captain continued the approach and landing without further complications. Both crew members are new in the aircraft and flying in unfamiliar surroundings. Busy time of flight -- ie, captain was doing an approach checklist when it would be better to pay attention. Back side of clock -- both crew members tired.

Title: AN MD11 MAKES AN APCH INTO SUBIC BAY, PHILIPPINES, AND PROGRAMS THE FMS IN ERROR. THE FLC ASSUMES THAT THE ACFT WILL FOLLOW AN OUTBOUND RADIAL, HOWEVER THE NAV SYS WILL NOT DO THAT AND THEY FLY OFF COURSE. APCH CTLR GETS THEM BACK ON COURSE.

Narrative: THE PROB AROSE DUE TO CONFUSION BTWN FMS AND HARD VOR INFO RECEIVED. THE CAPT AND FO ARE NEW IN ACFT TYPE NEITHER ONE EVER HAVING FLOWN THE MD11. THE PROB WAS DISCOVERED WHEN THE FO QUESTIONED THE (TO) POINT ON FMS INFO. ACFT WAS NOT NAVING TO THE VOR AND OUTBOUND ON THE OUTBOUND RADIAL AS PROGRAMMED (OR THOUGHT TO BE). APCH QUESTIONED WHAT WE WERE DOING ON THE WRONG RADIAL WHEN WE SIMULTANEOUSLY FIGURED OUT WHERE WE WERE. CORRECTED OUR FLT PATH AND THE CAPT CONTINUED THE APCH AND LNDG WITHOUT FURTHER COMPLICATIONS. BOTH CREW MEMBERS ARE NEW IN THE ACFT AND FLYING IN UNFAMILIAR SURROUNDINGS. BUSY TIME OF FLT -- IE, CAPT WAS DOING AN APCH CHKLIST WHEN IT WOULD BE BETTER TO PAY ATTN. BACK SIDE OF CLOCK -- BOTH CREW MEMBERS TIRED.
