All major aviation operations (flight, maintenance, air traffic  control, and airport) can induce substantial amounts of fatigue and  circadian disruptions on the humans conducting and managing those  operations. Select one of those aviation operations to analyze, then  evaluate the sources of fatigue which impacted that operation. Include  in your discussion how circadian rhythms can contribute to fatigue.  Next, creatively apply the implications of fatigue on that operation and  explain both how and why you believe it could negatively impact safety.  Finally, propose means for mitigating the associated fatigue and  improving safety in that operational field. As always, support your work  with a reliable source.
