Test and Evaluation of A Feasibility Model ILS Glide Slope Performance Assurance Monitor for the Final Approach Path.

摘要

The second of two test and evaluations was performed at the National Aviation Facilities Experimental Center (NAFEC), Atlantic City, New Jersey, to determine the feasibility of a ground-based monitoring system to accurately measure the flight-path of selected aircraft on the final approach path. This tracking information would provide a data base for statistical analysis of the instrument landing system (ILS) glide slope performance. This subsystem was tested by comparison of its measured glide slope angle with the glide slope angle generated by the NAFEC phototheodolite tracking system (time referenced). The data analysis indicates this glide slope monitor feasibility model was not adequate to perform as an ILS performance assurance monitor. The older test and evaluation is reported in FAA-RD-74-66, dated April 1974. (Author)
