In this paper has been described a new procedure by which the characteristic limit state line of a geometrically known slope can be calculated. This approach is based on an intuition, applied to a detreministic evaluation of slope stability, to look for a slope charecteristic "failure curve". Subsequently, concerning probability perspective, has been considered Low's interpreting the reliability index. Linking prior studies toghether and to the Characteristic Resistance Envelope Procedure, an Overall Approach has been developed. A simple computed case in included in oreder to show computing potentilities of thi new approach.
