This work aims to analyze three conceptual models of startle, surprise and automation bias found in the literature: Conceptual Model of Startle and Surprise, Integrated Model of Complacency, and Automation Bias and Conceptual Model of Threat, Appraisal and Information Processing. Afterwards, an analysis of accidents reports of Lion Air 43, Lion Air 610 (737-MAX), Emirates 407 and TAM 3054 is carried out using the selected conceptual models. The aim is to deepen the knowledge about startle, surprise and automation bias by means of an analysis of how they are found in recent accidents, disseminate the subject to the aeronautical community and reinforce their importance for aviation safety.
