Air traffic controller found asleep under a blanket at end of seventh night shift in nine days
At about 5:15 am, at the end of a 10 pm to 6 am shift, an approach controller responsible for the terminal airspace around a north Queensland regional airport was found asleep across two chairs at the workstation, leaving the airspace without an active controller for an unknown period. No aircraft were affected because traffic was very light. The Australian Transport Safety Bureau found the controller fell asleep because of the time of day, very low workload, a roster of multiple consecutive night shifts with reduced rest between blocks, and practices that increased the risk of sleep. It also found that rostering relied on short-notice tactical changes, so cumulative fatigue was not being managed strategically, and that supervisors were not treating low workload as a fatigue hazard.
