RELIABLE LINE SIGNALING TECHNIQUES FOR THE FAA GRN-27(V) AND CAT-III ILS

The purpose of these investigations is to reduce the effect of power line transients and lightning interference on solid state equipment. Specifically, this effort is directed toward protection of the GRN 27(V) and the FAA MARK III type Instrument Landing Systems. This report covers Phase I of the program. An overview of the problem and its solution is provided followed by the detailed analytical, experimental and design work that supports proposed system changes. The heart of these recommended system changes consists of changing the method of signaling from unblanced, non-isolated to a blanced, isolated configuration with tone signaling. The recommendations are to be implemented and tested at NAFEC during Phase II of the contract.
