Problem
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.
