Investigations for Improving Operational Reliability and Maintainability of Instrument Landing System Components. Volume 1. Text and Appendices

摘要

An investigation of anomalous performance of the glide slope at Lambert--St. Louis is reported. An analysis of Instrument Landing System (ILS) Reference Data Heights (RDH) is reported, as well as the results of an investigation of glide slope critical areas. A study into the feasibility of developing ground-based checking techniques for validating the Sideband Reference (SBR) glide slope is presented, as well as an assessment of the current standards and tolerances used to qualify glide slope structures. In addition, a proposed methodology for mathematical model validation is discussed.
