Hazards of cross-cultural communication failure in aviation

This study explores the hazard of cross-cultural communication failure on the flight deck focusing on how culturally homogeneous and heterogeneous crews operate in different cultural environments. Although Crew Resource Management (CRM) is largely built on Western cultural norms (North America and European), the nature of modern aviation places pilots from multiple cultural backgrounds on the flight deck. Although multiple studies have shown operational differences around the world, most studies focus on culturally homogeneous crews. The focus of this study was specifically heterogeneous crews. The research instrument was a survey distributed to 400 pilots employed by Part 121 scheduled airlines, or the international equivalent. Participants were split into a culturally homogeneous reference group, and three comparison groups based on their working country. Countries are grouped using a derived score based on Hofstede’s cultural dimensions of Power Distance (PD), Uncertainty Avoidance (UA), and Individualism (IDV). Responses were analyzed utilizing Pearson’s chi-square and Fisher’s exact test for comparisons. Additional exploratory analysis included survey response time. The findings indicate a statistically significant difference between culturally homogenous crews and heterogeneous crews. Reference group participants consistently had the highest rate of positive responses, with one exception, question 12. Importantly, even comparison group 1, which is culturally closest to the reference group, generally had a lower positive rate of response than the culturally homogeneous reference group. Expat status also showed significance in multiple questions, while when factored by native language differences appeared in the fewest questions. This suggests that differences are cultural rather than language based. Current CRM theory assumes low PD and high IDV and may not be optimal for all operations. While a good foundation, this research highlights the need for an industry-wide shift from a one size fits all CRM theory to a model that is more adaptive to operators’ specific needs, and the cultural context in which they operate. Further research is needed to explore more specific qualitative accounts of communication failures on the modern flight deck.
