Abstract. The authors develop and show the practical applicability of mathematical models for assessing the wear of equipment. According to the property of fixed assets, which equipment belongs to, it has to be replaced as a result of wear and tear. In this connection, the relevance of the conducted research is caused by the search of models for assessing their state at a given moment of time. The complexity of developing such models is due to the fact that the characteristics of equipment performance are random values and random functions. When planning the work of the enterprise it is necessary to take into account the statistical characteristics of the survivability of the equipment. Only in this way it is possible to foresee in advance the amount of renewable equipment, the order of preventive maintenance and the terms in which equipment should be replaced to ensure uninterrupted implementation of the production program without excessive investment expenditures of the enterprise.

Key words:  mathematical models, wear and replacement of equipment, optimization.

Abstract. The article presents an original formalizable logical-probabilistic model for the development of hazardous situations in flight, the use of which contributes to the deepening of the analysis of flight safety as a state of the air transport system, covering all its components and interfaces directly or indirectly involved, the current state of which determines the risk of an accident in each specific flight.

It is shown that the effectiveness of measures to reduce the risk of aviation accidents (prevention of aviation events) within the framework of the civil aircraft flight safety management system is largely determined by the level of organization, depth and quality of the investigation of aviation events.

The developed model is essential for organizing the collection of data and recording the results of aviation events investigation, as well as hazard and risk factors that pose a threat to the safety of civil aircraft flights. It allows you to implement a systematic approach to the investigation of aviation accidents, aviation incidents and their prerequisites, providing coverage of all directly or indirectly involved components of the air transport system and interfaces, the current state of which determines the risk of an accident in each particular flight.

The collection and registration of the results of the investigation of aviation events, data on hazard and risk factors for flight safety within the framework of the state system for managing the safety of civil aircraft flights on the basis of the developed model contributes to the fulfillment of the requirements of international and national legislation by all participants in the flight safety management process.

Key words: flight safety, dangerous situations, hazard factors, accident prevention factors, probability of development of a dangerous flight situation, investigation of aviation events.

Abstract. Modern automated aircraft is a system with high information value of its operation parameters. The motor skill of the pilot in the flight control modes using autopilot and auto-throttle remains untapped on such types of aircraft. This leads to a lack of information about the aircraft state in flight and increases the risk of an emergency. To solve this problem, the authors developed a new method that allows pilots to evaluate the functioning of complex control systems, based on the formation of an integrated skill in combining static and dynamic parameters from various sources of information located in the cockpit. This method is based on a mathematical model for assessing the effectiveness of the operator’s activities and allows developing a methodology for training pilots to assess the functioning of automated aircraft systems and the state of the aircraft itself in flight.

The method consists in the fact that when performing a flight in the semi-automatic control mode, the pilot must partially replace the autopilot with manual piloting. By executing the commands set on the flight mode control panel, the pilot is partially dependent on the operating conditions of the automatics involved in operation. The theoretical calculation shows that the flight should be divided into specific stages, and the parameters of the information sources presented to the pilot in flight should be divided into static and dynamic ones. When training, it is necessary to stepwise increase the information load on the pilot through the static parameters of the information sources, requiring the student to withstand them by influencing the dynamic parameters. It is also necessary to gradually change the level of automation of the piloting mode.

The results of the experiment made it possible to determine that the participants of the experimental group were 24% more effective in performing the flight when moving from a flight with a high degree of automation to a flight with a minimum degree of automation. The processing of the experiment results showed that using the proposed preparation method when evaluating the functioning of automated aircraft systems provided the statistically significant efficiency.

Abstract. The complication of aircraft maintenance processes in the aerodrome area under the influence of extreme, and often uncontrolled use of unmanned aerial vehicles, jeopardizes aircraft (AC) flight safety, entailing consequences from acts of unlawful interference and terrorist threats, danger to life and public health, environmental changes. This is the purpose of the study, which resulted in a new mechanism for ensuring safety through the development of a management systems integration model (IMS) and a flight safety management system (SMS). Particular attention is paid to the issue of introducing electronic IMS models in combination with SMS, the development of which is built taking into account the requirements of the management system and modern IT technologies that ensure the interconnection of the main, supporting processes and management processes, indicators of management processes, flight safety and parameters of the main business processes with the business characteristics of the aerodrome.

Abstract. When flying in automatic mode, the pilot is outside the manual control loop and functions as an operator in the system. Congestion of the visual channel of perception of information coming to the pilot, the need to intervene in control through the influence of the pilot on the program of operation of the aircraft, and not through controls, leads to a change in the operational field of activity of pilots. To develop new piloting skills as part of the operator’s duties as a pilot, a different critical view of research in this area is needed.
