Instrument Landing System Improvement Program.

Abstract

Results are presented of the fourth year technical investigations to provide improvement in ILS performance. Major emphases were on development of mathematical models for predicting (1) effects on the glide slope and localizer; and (2) effects of irregular ground on image-type glide slopes. The design, development and testing of an Automatic Tracking Radio Theodolite is reported upon as well as the effects of truncated grounds upon image glide slopes. Results have been obtained from analyses of snow cover effects on the glide slope, methods of minimizing parasitic currents in V-Ring Localizer arrays and the minimization of over-flight effects on localizer monitors. Conclusions and recommendations for improvements in the glide slope performance at specific sites are presented from work done in providing special consultations at Detroit and Pittsburgh.
