The Impact of Operator State on Pilot/ATC ConflictEmpirical laboratory research has shown that a number of operator state factors may influence the quality of situation assessment, information processing, and decision making behavior. Few of these effects have been examined during high-risk decision making in highly automated environments. Many of these states may be induced by the conditions of flight themselves, such as information overload, frustration, or fatigue. Conflict within a flight crew or between flight crews and ATC can both exacerbate these states and be affected by them. Through examination and coding of ASRS incident reports we are addressing four questions: 1) How are different types of pilot/ATC conflict (operational, informational, cognitive) associated with words indicative of operator state? 2) In which type of conflict are operator state terms most likely to be in the narrative? 3) What operator state terms are associated with appropriate vs. inappropriate (e.g., social pressure) conflict resolution strategies? 4) When/what type of conflict situation is associated with differences in risk perception between pilots and ATC? What operator states are involved or inferred? This research will enable us to better predict particular operator states, situations, and differences in risk perceptions that may impact pilot/ATC interactions and ultimately the safety of Next Gen operations. |
