Narrative:
We had had a sick passenger and the possibility existed for an emergency landing. We inserted our emergency field coordinates with the INS (waypoint 9). The emergency did not materialize. We forgot to reinsert the real waypoint 9. Upon passing 8, the aircraft began a left-hand turn. By the time we discovered our mistake we were well off course and arwy. We don't believe we were in radar contact and center never asked about our course, but the possibility for conflict could have existed. The captain (instrument) was out of the cockpit, and the copilot was on his first flight (widebody transport IOE). The copilot and I should have checked #9 coordinates when the alert lights came on (sopa, procedural). I was busy trying to call in a position report and could not find a station who could receive. I guess the copilot forgot to check or didn't notice the alert light, either.

Title: ACR HAS SICK PASSENGER. REPROGRAMS INS TO DEVIATE. FORGETS TO ENTER CORRECT WAYPOINT WHEN DEVIATION NOT NECESSARY. HEADING DEVIATION OFF AIRWAY.
Narrative: WE HAD HAD A SICK PAX AND THE POSSIBILITY EXISTED FOR AN EMER LNDG. WE INSERTED OUR EMER FIELD COORDINATES WITH THE INS (WAYPOINT 9). THE EMER DID NOT MATERIALIZE. WE FORGOT TO REINSERT THE REAL WAYPOINT 9. UPON PASSING 8, THE ACFT BEGAN A LEFT-HAND TURN. BY THE TIME WE DISCOVERED OUR MISTAKE WE WERE WELL OFF COURSE AND ARWY. WE DON'T BELIEVE WE WERE IN RADAR CONTACT AND CENTER NEVER ASKED ABOUT OUR COURSE, BUT THE POSSIBILITY FOR CONFLICT COULD HAVE EXISTED. THE CAPT (INSTR) WAS OUT OF THE COCKPIT, AND THE COPLT WAS ON HIS FIRST FLT (WDB IOE). THE COPLT AND I SHOULD HAVE CHKED #9 COORDINATES WHEN THE ALERT LIGHTS CAME ON (SOPA, PROCEDURAL). I WAS BUSY TRYING TO CALL IN A POS RPT AND COULD NOT FIND A STATION WHO COULD RECEIVE. I GUESS THE COPLT FORGOT TO CHK OR DIDN'T NOTICE THE ALERT LIGHT, EITHER.
