Abstract:

This document summarizes the results of a three-dimensional area navigation flight test. Horizontal error parameters evaluated included navigation sensor VORDME error, flight technical error, computer and total system error. Vertical error parameters evaluated included altimetry error, flight technical error, vertical error due to along track error, computer error, and total system error. Three vertical profiles were flown in a six segment test route three-degree climbs, three degree descents, and a six degree descent. Statistical evaluations were performed on the data and resulting values were then compared to FAA Advisory Circular 90-45A values. Statistical envelope plots for each segment and error type were generated as aids in evaluating the data. Tabular listings, by flight segment, are provided for each error type, as well as route summaries.
