Available in PDF, EPUB and Kindle. Book excerpt: Results of tests to determine the effect of snow on image glide path systems are presented. Effects on three systems, capture effect, null reference, and sideband reference are discussed in terms of change in the far-field signal characteristics. Data includes; far-field signals such as received in the aircraft, conventional near-field monitor signals, analog, integral-monitor signals, and trends of the signals as a function of environmental condition. The primary conclusions are that new snow depths less than eight inches do not generally cause a change in the path but a change in the snow surface condition such as during a thaw tends to make the path move upward as if the ground plane were simply elevated. The conclusions agree with theoretical predictions. (Author).

This book was released on 1975 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of the tenth consecutive year of data collection concerning snow effects on operation of image glide-slope systems are presented. Evidence continues to show that with snow on the reflecting ground plane, the far-field glide slope does not lower; rather it tends to rise approximately one-tenth of one degree elevation per one foot depth of snow. Further, the conventional near-field, 180 deg. point monitor response does not correlate with far-field path performance when snow covers the ground. A two-frequency, capture-type far-field monitor was tested. Conditions surrounding the collection of data on snow effects are severe enough to produce considerable noise in the data, and this prevents correlations that do exist from appearing in an elegant form.
