Keith Richard Greenaway

Keith Richard Greenaway , who died on 21 May 2010, aged 94, established himself early in his career as the pre-eminent authority in north America on Arctic air navigation. He was only a flight lieutenant, RCAF, with 11 years service when he published his Arctic air navigation (1951), which immediately became the standard textbook in its field. The book deals with all aspects of air navigation, bringing information scattered in various publications together with the author's already very wide practical experience. The heart of the book details the limitations of the magnetic compass in high latitudes and sets out procedures in the reliable Asco-Gyro system of navigation, which Greenaway did so much to develop and which involves the determination of aircraft heading by astro compass and the maintenance of direction by gyro compass, continuously corrected for gyro-drift
