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), specifically Aviation English, 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. English in Global Aviation teaches readers how to apply linguistic research to real world, practical settings. The book uses a range of corpus-based findings and related research to provide an effective analysis of the language needs of the aviation industry and an extended look at linguistic principles in action. Readers are presented with case studies, transcriptions, radiotelephony, and a clear breakdown of the common vocabulary and phrasal patterns of aviation discourse. Students and teachers of both linguistics and aviation will discover the requirements and challenges of successful intercultural communication in this industry, as well as insights into how to teach, develop, and assess aviation English language courses. This book explains why and how English became the lingua franca of aviation. It demonstrates through the history of accidents and near-misses, together with research findings, that mastery of phraseology is insufficient for safety of flight. Experts in their area, the writers narrate the story in academic and professional voices, making this an authoritative work on the topic, and keeping the reader interested from cover to cover.
