Method of modelling loss of spatial orientation by crews and identification of risks of large rolls

摘要

A method of modelling loss of spatial orientation (LSO) by crews and identification of risks of large rolls consists in that an area of acceptable and unacceptable risks is determined by probable distribution of flight. At the same time, when flying under normal conditions following operations are made: determination of normal distribution of flight parameters, transformation of alternating parameters (roll) according to the modulus, statistical processing modular histograms, smoothing modular histograms by the method of least squares, separation of a canonical part of modular distribution of parameters, verification of a canonical part (Kolmogorov, Pearson) according to the fitting criteria, definition and approximation of the "tail" of non-canonical part, definition of high-risk areas by a ratio of the area of canonical part and the "tail" of distribution, measurement of the risk level as the ratio of areas, assessment of the risk level from the point of view of acceptability or unacceptability, conducting anti-stress training of flight crews of aircraft of new generations with signalling of the parameters according to regulatory documents, while on flights in special situations a direct transformation (transformation of distribution law) is conducted, transition from normal to log-normal distribution law, analysis of the parameters of log-normal distribution, increasing the efficiency of flight operations, development of the measures for anti-stress training the flight crews of new generations with index signalling the parameters according to the regulatory documents.
