Going from a 727 to a 767 meant isolating electrical smoke was no longer possible. The pilots didn't have the time to deal with what the FE did. The checklist was simplified to basically land at the nearest suitable airport and let it burn. The day I had electrical smoke in the whole aircraft I shut some non essential busses off immediately then did our simplified checklist. Wish we had an FE that day. It will really get interesting when they get down to one pilot operations.
