Taking readers step-by-step through the major issues surrounding the use of English in the global aviation industry, this book provides a clear introduction to turning research into practice in the field of English for Specific Purposes (ESP) and a valuable case study of applied linguistics in action. With both cutting-edge research and evidence-based practice, the critical role of English in aviation is explored across a variety of contexts, including the national and global policies impacting training and language assessment for pilots, air-traffic controllers, ground staff and students. Readers are presented with key case studies, transcriptions, radiotelephony, and a clear breakdown of the common vocabulary and phrasal patterns of aviation discourse. An essential resource for students and teachers of both linguistics and aviation, English in Global Aviation reveals the requirements and challenges of successful intercultural communication in this industry and offers insights into how to teach, develop, and assess aviation English language courses.
