Airline Pilot Risk Profiling By Using Unstable Approach Management Case, Selim Ozyurek 2023 Western Michigan University

Airline Pilot Risk Profiling By Using Unstable Approach Management Case, Selim Ozyurek

National Training Aircraft Symposium (NTAS)

Risk and human decision-making cannot be separated from each other. Many of theories and studies have tried to analyze pilots’ decision-making processes, risk factors, and preference behavior in the aviation domain. Unstable approaches are fairly infrequent, but an unstable approach is a major risk factor for landing accidents (Smith & Curtis, 2013; Smith, Jamieson, & Curtis, 2012). Therefore, the decision to execute a go-around if an approach is not sufficiently stable is encouraged in the interest of safety (Airbus Customer Services, 2012; Flight Safety Foundation, 2013), but in practice less than 5% of the unstable approaches actually results in a …
