Narrative:

While flying at FL390 between fargo and bismarck, nd, we experienced a very strong, pungent odor of possible electrical origin, followed immediately by smoke in the cockpit. The smoke was coming from the area around the front instruments and was mixed with cooling air that normally flows over the panel. The captain and I immediately put on our oxygen masks (100 percent), pulled the smoke goggles out of the side panels and declared an emergency with ZMP. I requested an immediate descent and vectors to the nearest suitable airport that could accommodate a B767. We accomplished the smoke identify and removal checklist, emergency descent checklist, and coordinated with ZMP (and later bismarck approach control) for vectors to bis. After starting our descent, the lead flight attendant was asked to come to the cockpit and briefed on the situation. After returning to the cabin, she called the cockpit back and stated that a company employee had idented himself as a B767 first officer based at nyc. He wanted to know if we could use his assistance in the cockpit. We readily accepted hi offer -- great assistance in 2-PERSON cockpit during an emergency. After descending through FL200 we received a message on the EICAS status screen 'standby inverter.' during the descent we were handed over to bis approach control and were told to expect an ILS approach to runway 31. We do not carry commercial charts for bis. I informed approach control of that fact and requested the ILS frequency and course to runway 31, as well as the VOR frequency. The controller stated that he was not sure of the 'exact' inbound course to runway 31. At that point another air carrier flight came up on frequency and provided the course, frequencys, and minimums for our use on the approach to bis. We requested from approach control to have the emergency equipment and fire trucks to standby during our landing. We completed all checklists and received vectors for an ILS approach to runway 31 at bis. Upon an uneventful landing, we were followed to the air carrier airline gate by emergency fire equipment. No evacuate/evacuation of passenger was necessary. No injuries.

Title: B767 ACFT IN CRUISE HAD ELECTRICAL SMOKE. FLC DONNED OXYGEN, DECLARED AN EMER, COMPLETED CHKLISTS AND DIVERTED TO NEAREST SUITABLE ARPT. EICAS SHOWED 'STANDBY INVERTER' WHICH WAS PROBABLE SMOKE SOURCE.

Narrative: WHILE FLYING AT FL390 BTWN FARGO AND BISMARCK, ND, WE EXPERIENCED A VERY STRONG, PUNGENT ODOR OF POSSIBLE ELECTRICAL ORIGIN, FOLLOWED IMMEDIATELY BY SMOKE IN THE COCKPIT. THE SMOKE WAS COMING FROM THE AREA AROUND THE FRONT INSTS AND WAS MIXED WITH COOLING AIR THAT NORMALLY FLOWS OVER THE PANEL. THE CAPT AND I IMMEDIATELY PUT ON OUR OXYGEN MASKS (100 PERCENT), PULLED THE SMOKE GOGGLES OUT OF THE SIDE PANELS AND DECLARED AN EMER WITH ZMP. I REQUESTED AN IMMEDIATE DSCNT AND VECTORS TO THE NEAREST SUITABLE ARPT THAT COULD ACCOMMODATE A B767. WE ACCOMPLISHED THE SMOKE IDENT AND REMOVAL CHKLIST, EMER DSCNT CHKLIST, AND COORDINATED WITH ZMP (AND LATER BISMARCK APCH CTL) FOR VECTORS TO BIS. AFTER STARTING OUR DSCNT, THE LEAD FLT ATTENDANT WAS ASKED TO COME TO THE COCKPIT AND BRIEFED ON THE SIT. AFTER RETURNING TO THE CABIN, SHE CALLED THE COCKPIT BACK AND STATED THAT A COMPANY EMPLOYEE HAD IDENTED HIMSELF AS A B767 FO BASED AT NYC. HE WANTED TO KNOW IF WE COULD USE HIS ASSISTANCE IN THE COCKPIT. WE READILY ACCEPTED HI OFFER -- GREAT ASSISTANCE IN 2-PERSON COCKPIT DURING AN EMER. AFTER DSNDING THROUGH FL200 WE RECEIVED A MESSAGE ON THE EICAS STATUS SCREEN 'STANDBY INVERTER.' DURING THE DSCNT WE WERE HANDED OVER TO BIS APCH CTL AND WERE TOLD TO EXPECT AN ILS APCH TO RWY 31. WE DO NOT CARRY COMMERCIAL CHARTS FOR BIS. I INFORMED APCH CTL OF THAT FACT AND REQUESTED THE ILS FREQ AND COURSE TO RWY 31, AS WELL AS THE VOR FREQ. THE CTLR STATED THAT HE WAS NOT SURE OF THE 'EXACT' INBOUND COURSE TO RWY 31. AT THAT POINT ANOTHER ACR FLT CAME UP ON FREQ AND PROVIDED THE COURSE, FREQS, AND MINIMUMS FOR OUR USE ON THE APCH TO BIS. WE REQUESTED FROM APCH CTL TO HAVE THE EMER EQUIP AND FIRE TRUCKS TO STANDBY DURING OUR LNDG. WE COMPLETED ALL CHKLISTS AND RECEIVED VECTORS FOR AN ILS APCH TO RWY 31 AT BIS. UPON AN UNEVENTFUL LNDG, WE WERE FOLLOWED TO THE ACR AIRLINE GATE BY EMER FIRE EQUIP. NO EVAC OF PAX WAS NECESSARY. NO INJURIES.
