Theoretical Approaches for Safety Levels Measurements – Sequential Probability Ratio Test (SPRT)

Abstract

The principles of civil aviation safety are considered. At present time, aviation is an ultra-safe system, (i.e. a system that experiences less than one catastrophic safety breakdown every one million production cycles). But, unfortunately, we can never state that aviation activities will be absolutely safe. In current conditions the increase of the civil aviation safety level is one of the principal objectives of the world air transport development. The paper pays special attention to the civil aviation threats and risks in the context of globalization processes. The investigation deals with problems of global implementation of Annex 19 to the Convention of the International Civil Aviation. Present research paper discusses new theoretical approaches to searching for methods to assess the “safety space” of civil aviation activity. Special attention is paid to an effective test, proposed by A. Wald.
