Introducing a framework for understanding the rehtionship between human error and aviation safety from multiple perspectives and using multiple models.The first part of the framework is the perspective of individual operator using the information processing model.The second part is the group perspective with the Crew Resource Management(CRM) model.The third and final is the organization perspective using Reasons Swiss cheese model.Each of the perspectives and models has been in existence for a long time,but the integrated framework presented allows a systematic understanding of the complex relationship between human error and aviation safety,along with the numerous factors that cause or influence error.The framework also allows the identification of mitigation measures to systematically reduce human error and improve aviation safety.
