This thesis examines miscommunications in global transportation through the lens of conversational analysis. It focuses on the KLM, Pan American, and Avianca crashes that occurred in 1990 and 1977, which resulted in a tragic loss of life. It is the objective of this study to examine the mechanisms by which the pilots and air traffic controllers miscommunicated leading up to the accident. An analysis of transcripts from the cockpit voice recorder and communications with air traffic control are used in this study, as well as an examination of earlier studies in the field. Using conversation analysis, the study identifies and describes patterns of miscommunication between the pilots and air traffic controllers as well as their impact on flight safety. Study findings illustrate the complexity of miscommunication in global transportation as well as the potential risks associated with inadequate communication. The study found that aviation as a global workplace faces many communication-related challenges. Language barriers, cross-cultural communication difficulties, English proficiency issues, and pronunciation and dialect effects on communication all contribute to the conclusion that changes are needed with regards to communication in the aviation industry to reduce the risk of further accidents. Furthermore, the study emphasises the importance of effective communication in the aviation industry, as well as the need for ongoing training and education for pilots and air traffic controllers.
