The thesis explores the impact of multicultural and monocultural environments on Crew Resource Management (CRM) education delivery. It traces the historical development of CRM, emphasizing the importance of non-technical skills in aviation. Through surveys and interviews with students from different cultural backgrounds, the research reveals that multicultural environments enhance communication, English fluency, and adaptability, while monocultural settings improve teamwork and conflict resolution. However, each environment presents specific challenges, such as social toxicity in monocultural settings and initial adaptation difficulties in multicultural ones. The findings suggest that CRM training programs need to be tailored to address these differences to optimize effectiveness and improve aviation safety. The study offers actionable recommendations for enhancing CRM education.
