"Patter" is the term given by flying instructors to the language they use whilst demonstrating training exercises in the air. It is a very special language as it has to be precisely co-ordinated with control movements and absolutely lucid. "Patter" is also a picture language because the art of flying is largely about visual cues. The good flying instructor should know these cues and a prime object of this book is to highlight them, not only in the text, but with matching pictures as seen from the cockpit. "The Patter book" is the first flying manual ever to record verbatim the language of the flying instructor as spoken in the air.
