On the Containment Band of Position Errors for the Required Navigation Performance

Abstract

The required navigation performance (RNP) is a statement of navigation accuracy of aircraft. The RNP type is represented by 95% containment band of errors. The meaning of the containment band differs corresponding to the dimension of errors, e.g., one-dimensional or two-dimensional. Both dimensions are used for describing RNP types in the aviation world. In this paper, the two-dimensional (circular) containment is compared with one-dimensional one assuming the Gaussian and the double exponential (DE) error distributions. Results and several problems are discussed herein.
