A statement of the navigation performance necessary for operation within a defined airspace. QRNP type. A containment value expressed as a distance in nautical miles from the intended position within which flights would be at least 95% of the total flying time E.g. RNP4 represents a navigation accuracy of +/- 4 NM on 95% basis QRequired Navigation Performance (RNP). A statement of the navigation performance necessary for operation within a defined airspace.
