Abstract : This report describes the methodology and results of Phase 2 and 3 of a four-phase program. The objective of the four-phase program is to measure and model navigational performance of aircraft making Instrument Landing System (ILS) approaches at distances from 10 to 32 nautical miles from the runway threshold. Navigation of the localizer at these distances is envisioned for simultaneous instrument approaches into parallel triple and quadruple runways. Knowledge of navigational performance will facilitate evaluation of triple and quadruple approach concepts and may identify ways to reduce Total Navigational System Error, which, in turn, may make triple and quadruple approach concepts more viable. The objective of Phase 2 was to quantify the bias in airport surveillance radar (ASR)-9 target position reports, and to provide correction factors to account for this bias in the Phase I calculation of cross-track deviation (CTD). The objective of Phase 3 was to determine the location of the ILS localizer course centerline (CL), half-scale, and full-scale course deviation indicator signals relative to the extended runway centerline, and to provide data on localizer CL location for use in Phase 1 CTD calculations.
