Abstract: Fully automatic Omega Navigation Systems have been demonstrated and are beginning to be used operationally in aircraft and other vehicles. A natural question is the accuracy achieved by such systems. Concern over the probability of maintaining correct lane identification complicates this question. Use of the root-mean-square (rms) statistics is shown to be a misleading measure of operational performance. Alternate methods of specifying the navigational errors of automatic Omega navigators are discussed. Cumulative percentile plots are recommended for the specification of errors. Use of Weibull probability paper to study radial error trends is demonstrated. Illustrations of error analysis techniques are given, based on actual Omega flight test data.
