Check Your Aviation English has been specifically designed for aviation professionals, particularly pilots and air-traffic controllers, to help them achieve and maintain ICAO Level 4. It contains 30 units of listening and speaking exercises, providing realistic practice of both Plain English and Radiotelephony as well as focussing on key vocabulary development. There are regular progress and review tests providing further practice and consolidation of important language points. All Radiotelephony extracts have been checked and verified for accuracy and authenticity by Oxford Aviation Academy. The perfect supplement for every aviation English classroom, Check Your Aviation English can be used to accompany any aviation English course but is also the ideal self study package. The answer key and listening script are included in the book while the accompanying CDs provide all the audio material for the exercises.
