Narrative:
During cruise flight on a revenue passenger flight from cincinnati, oh (cvg), to montreal, canada (yul), at FL290, approximately 40- 50 mins into the flight I was computing an estimated landing weight for the aircraft. I then lost consciousness for what the captain informed me was approximately 30 seconds. As I regained consciousness, the captain was saying my name to see if I was ok and inquired of my current condition. I informed him that I did not feel any adverse symptoms or degradation of my senses. I was able to perform my duties as normal and continued to do so. We continued to montreal without any further problems and landed safely.
