These exercises are intended for developing students' ability to recognize cognates commonly used in air technical communications. All exercises are to be conducted orally with emphasis on correct pronunciation. Each lesson is presented in two parts: (1) pronunciation drill, and (2) fill-in exercises (oral drills). Aside from English instructions for the oral drills, the text is written in Cyrillic script. Appendixes contain extensive lists of noun, adjective, and miscellaneous cognates. (RL)
