Abstract : An evaluation was conducted at the National Aviation Facilities Experimental Center (NAFEC), Atlantic City, New Jersey, to determine the feasibility of a ground monitoring system to accurately detect the path of selected aircraft when on final approach and to eventually use this tracking information to provide a data base for statistical analysis of the Instrument Landing System (ILS) glide slope and localizer performance. The interferometer system (test system) was evaluated by comparing conic angles generated by the interferometer to conic angles generated by the NAFEC phototheodolites during flight approaches (time-paired). Analysis of the data revealed that the interferometer system was not adequate to effectively perform as an ILS performance assurance monitor. (Author)
