Near-Misses-Line: Visualization of the Edge Between Safety and Danger

This research explores the concept of near-misses in aviation safety, defining them as events that almost led to accidents but were mitigated. It introduces the "near-misses-line," which separates safety from danger, emphasizing the importance of understanding factors like practical drift and normalization of deviance. The study proposes a new safety analysis model for assessing near-misses and improving risk management strategies, focusing on flight deck crews navigating standard procedures versus operational flexibility.
