Abstract:

Evaluations and performance analysis are presented for Dallas-Fort Worth, TX, Wheeling, WV. Bristol, TN, Parkersburg, WV. Pontiac, MI. and DeKalb-Peachtree, GA. An investigation of anomalous performance of the glide slope at Lambert-St. Louis is reported. An analysis of Instrument Landing System ILS Reference Datum Heights RDH is reported, as well as the results of an investigation of glide slope critical areas. A study into the feasibility of developing groundbased checking techniques for validating the Sideband Reference SBR glide slope is presented, as well as an assessment of the current standards and tolerance used to qualify glide slope structures. In addition, a proposed methodology for mathematical model validation is discussed. Author
