Abnormal situations in flight arise when an aircraft in normal flight mode is exposed to one or more unfavourable factors. Therefore, such situations have a pronounced random nature. To assess the degree of danger of contingencies, it is convenient to use the Airworthiness Standards governing the list of situations and probability of their occurrence in flight. The degree of danger can be determined from the assumption that during the life of the aircraft each of the four contingencies will give the same level of risk. By combining all contingency situations with their normalized indicators and using this assumption, we can quantitatively determine their degree of danger (risk level) in the form of probabilistic indicators.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
