An Integrative Review on the Effectiveness of Crew Resource Management between Flight Deck and Cabin Crew

This study presents a narrative review of 37 empirical studies published over the past decade, aiming to examine the impact of crew resource management (CRM) practices between pilots and cabin crew on aviation safety and organizational effectiveness.The literature was classified into four domains: (1) effectiveness of CRM training and safety outcomes, (2) communication and information sharing between cockpit and cabin, (3) delegation of authority and role clarification, and (4) variations in CRM performance across cultural, gender, and experience-related factors.Comparative analysis of research designs, sample characteristics, statistical methods, and findings confirmed that CRM functions not merely as technical training, but as a core strategy for strengthening airline safety culture and inter-occupational collaboration.Integrated simulation-based training, standardized communication, and explicit authority delegation emerged as critical for faster and more accurate crisis response.Moreover, cultural background, gender, and professional experience produced significant differences in CRM effectiveness.This review provides theoretical and practical foundations for improving integration, continuity, and customization of CRM training in airlines, while suggesting future directions such as applying real-time big data analytics and pursuing cross-industry comparative research.
