The purpose of this thesis was to research how well native and non-native English speakers proficiently communicated using learned Air Traffic Control (ATC) phraseology, and how well they communicated using plain phraseology. The participants in this study were Embry-Riddle Aeronautical University (ERAU) flight students at the Daytona Beach campus. This study used a sample of students from English-speaking countries and a sample of students from non-English speaking countries. A quantified study of the types of communication errors was conducted by listening to a pre-defined amount of voice communications between the Daytona Beach International Airport tower facility and ERAU flight student participants. In addition to analyzing the types of communication errors, this study determined if the participants met minimum English Language Proficiency (ELP) standards. There was no significant difference in communication errors between the two groups. Both groups met minimum English Language Proficiency (ELP) standards.
