As we move into NextGen (Next Generation) aviation operations, it becomes critical to ensure sharedsituational understanding and cooperative problem solving between flight crews and ATC. Doing so willentail identifying potential problems, as well as evaluating the likely impacts of specific operator and environmentalcharacteristics on decision processes and outcomes. Aviation Safety Reporting System (ASRS)and National Transportation Safety Board (NTSB) incident and accident reports were examined, with a focuson human factors issues, antecedents of errors and associated operational consequences. Results showedinterrelationships between specific antecedents and errors, and the prevalence of attention errors, crewcommunication issues and monitoring/challenging errors in procedural errors and poor decisions. A modelof how antecedents contribute to poor situational models and outcomes is proposed.
