ANALYSIS OF FACTORS AFFECTING THE OPERATIONAL EFFECTIVENESS OF AIRCRAFT CONTROL SYSTEMS

Abstract

The article highlights the mismatch between existing design approaches and the conditions of modern combat operations, as reliability assessment is often conducted only for individual factors in isolation. Based on the system analysis, the authors identified and classified three main groups of influencing factors: natural (meteorological conditions, geophysical factors, and physical effects), anthropogenic (combat conditions, man-made interference, and the human factor), and technical (hardware, information-processing and algorithmic, and dynamic factors). Their components and the nature of each factor’s impact on the aircraft control system are described in detail. Based on the results of the analysis, three detailed structural-hierarchical diagrams of the influencing factors have been developed. The generalized structural-hierarchical framework allows for a comprehensive consideration of internal and external threats that arise throughout the entire aircraft lifecycle and directly affect combat employment effectiveness. The authors substantiate that the reliability and operational effectiveness of an aircraft control system must be considered as equivalent and interrelated characteristics. The created structural-hierarchical framework will serve as a foundation for the subsequent determination of the minimum necessary set of properties that modern and prospective aircraft control systems must possess.
