Narrative:
Lost the left main AC bus at FL360. QRH checklist was performed and system restored. While running checklist noticed speed was slow. Told pilot flying to correct and he did. Continued to our filed destination and landed under normal conditions. Always take time to monitor primary flight instruments while reading and accomplishing a QRH procedure. Do not assume the pilot flying is in full control of aircraft.
