Purpose In this study, a multi-criteria decision-making (MCDM) approach for evaluating airworthiness factors were presented. The purpose of this study is to develop an acceptable rationale for operational activities in civil and military aviation and for design, production and maintenance activities in the aviation industry that can be used in-flight safety programs and evaluations. Design/methodology/approach In aviation, while the initial and continuing airworthiness of aircraft is related to technical airworthiness, identifying and minimizing risks for avoiding losses and damages are related to operational airworthiness. Thus, the airworthiness factors in civil and military aviation were evaluated under these two categories as the technical and operational airworthiness factors by the analytic hierarchy process and analytic network process. Three technical and five operational airworthiness criteria for civil aviation, three technical and nine operational airworthiness criteria for military aviation were defined, evaluated, prioritized and compared in terms of flight safety. Findings The most important technical factor is the “airworthiness status of the aircraft” both in civil (81.9%) and military (77.6%) aviation, which means that aircraft should initially be designed for safety. The most significant operational factors are the “air traffic control system” in civil (30.9%) and “threat” in the military (26.6%) aviation. The differences within factor weights may stem from the design requirements and acceptable safety levels (frequency of occurrences 1 in 107 in military and 1 in 109 in civil aircraft design) of civil and military aircraft with the mission achievement requirements in civil and military aviation operations. The damage acceptance criteria for civil and military aircraft are different. The operation risks are accepted in the military and acceptance of specific tasks and the risk levels can vary with aircraft purpose and type. Practical implications This study provides an acceptable rationale for safety programs and evaluations in aviation activities. The results of this study can be used in real-world airworthiness applications and safety management by the aviation industry and furthermore, critical factor weights should be considered both in civil and military aviation operations and flights. The safety levels of airlines with respect to our airworthiness factor weights or the safety level of military operations can be computed. Originality/value This is the first study considering technical and operational airworthiness factors as an MCDM problem. Originality and value of this paper are defining critical airworthiness factors for civil and military aviation, ranking these factors, revealing the most important ones and using MCDM methods for the evaluations of airworthiness factors for the first time. In civil aviation flight safety is the basic tenet of airworthiness activities in risk analysis, on the other hand in military aviation high levels of risks are to be avoided in peace training or operational tasks. However, even high risks have to be accepted during the war, if the operational requirements impose, as mission achievement is vital. The paper is one of a kind on airworthiness evaluations for flight safety.

Methodological Approaches

The article describes a new class of organizational and technical systems - intelligent aviation systems, whose operational principles provide the increased safety of an aircraft flight. The development of systems of this class is primarily explained by the need to record statistical data on the main causes of aviation accidents (human factor - up to 87%, failure of aviation equipment - up to 15%, external factors - 2% of all cases). A scientific problem is formulated related to the importance of creating methods for assessing and predicting the threat of an accident based on direct control of changes in the values of characteristics that affect flight safety. For this, it is proposed to use the methods and means of the scientific and technical direction of artificial intelligence, which will reveal the immediate causes of an aviation accident and prevent them using the flight safety management system. The technical characteristics are considered, the properties of the system under study are presented, which determine the principles of its functioning: intelligence, information content, speed, controllability, interdependence of subsystems, flight safety, including identification of the threat of an accident, its prediction and parry. The above principles of the functioning of the system under study, which are part of the methodology for managing the safety of an aircraft in flight, are implemented in a set of methods and algorithms. Among them should be noted the intelligent method for assessing the threat of an aviation accident, the method for predicting the threat of an accident, the method for supporting decision-making by the crew in the event of the threat of an accident, as well as the method for synthesizing the control law for countering the threat

Abstract The algorithm for bird radar echo selection was developed in Israel and has been successfully used for many years to monitor birds in periods of massive intercontinental migration in order to ensure flight safety in civil and military aviation. However, it has been found that under certain meteorological conditions the bird echo selection algorithm does not filter out false signals formed by atomized clouds and atmospheric inhomogeneities. Although the algorithm is designed to identify and sift false signals, some useful echoes from smaller birds are erroneously sifted as well. This paper presents some additional features of radar echoes reflected from atmospheric formations that can be taken into account to prevent the loss of useful bird echoes. These additional features are based on the use of polarization, fluctuation and Doppler characteristics of a reflected signal. By taking these features into account we can reduce the number of false signals and increase the accuracy of the bird echo selection algorithm. The paper presents methods for using radar echoes to identify species and sizes of birds, together with recommendations on using the data to ensure flight safety during periods of massive intercontinental bird migration.

The paper introduces and analyzes the results of research into the development of anti-aircraft missile systems through the example of the first Russian anti-aircraft missile system S-25. The study describes the capabilities of the anti-aircraft missile system as the implementation of the requirements specifications in the context of the development of military aviation technology and electronic warfare means and emphasizes the importance of cooperation between enterprises — developers of guided missile weapons. Although the latter issue is poorly covered in the Russian scientific, technical, and educational literature, it is an important problem in organizing the development of missile systems. The paper is the first to provide detailed data on the content and timing of the stages of modernization of the S-25 system, and also presents graphic material that clearly demonstrates the change in the capabilities of the S-25 system due to an intensive change in the characteristics of military aircraft.

The military professional training of cadets-military pilots in a military aviation university is conditioned by the trends in the development of military education, its prompt response to the personnel needs of the troops. Aviation units need military pilots who are ready to fulfill the official duties of crew commanders, to solve the urgent task of ensuring flight safety. Training of flight personnel for military aviation does not fully take into account the need to form cadets' competencies as an aviation commander and teacher, which will contribute to ensuring flight safety and increasing the combat potential of aviation units and subunits. The article deals with the problem of flight safety as a factor affecting the national security of Russia, paying attention to the causes of accidents and pilot errors. In the course of the study, it was proved that the military-professional activity of cadets-military pilots is the process of solving professional tasks that ensure the combat readiness of aviation units while observing flight safety conditions. Based on the content analysis of the command and methodological professional tasks based on the activity approach, the leading role of the command-methodological activity has been established. The functional approach and the principle of identification made it possible to identify the functions of the leading command-methodological activity (military flight training and educational, organizational and managerial). Arguments are given regarding the development of cadets not only a set of abilities for command-methodological activity, but also professionally important qualities that integrate command-methodological competence. The structure of competence (motivational-value, cognitive, activity components) is determined taking into account the specifics (leading type of activity) and features (a set of command and methodological professional tasks) of military professional activity. The criteria for the formation of the components of the command-methodical competence (professional purposefulness, intellectual potential, professional responsibility) have been identified. The methodological basis of the pedagogical system for the formation of the command-methodical competence of cadets-military pilots was formed by the system-structural, personality-activity, functional, modular, adaptive, technological and competence-based approaches. The results of the experimental work carried out in the branch of Military Educational-Research Centre of Air Force Air Force Academy in Syzran confirmed the dependence of the cadets' readiness for flight safety activities on the formation of command-methodological competence.

Based on the analysis of statistical data on the number of aviation accidents per 100 thousand flight hours for the period of 1960-2012, the article proposes the use of periodogram as a method of spectral analysis to detect cycles and determine whether there is any indication of flight safety management system at different time intervals. It shows that strategic influences on safety system (within stable and well-functioning management structure) directly and extensively shape the trend of relative safety indicator.

The Military

Last year the Aëronautical Society kindly asked me to give my views on Military Aviation. I then tried to show the objects for which military aircraft would be used, the results likely to be gained, and the general lines upon which it was expected that progress would take place—in a word, the military aspect of aviation. Airships have now been handed over to the Naval Wing of the Royal Flying Corps and I propose to–night to deal almost entirely with aeroplane work, in the light of a year's progress. I make no excuse for reiterating the strong links which I feel bind soldier, sailor, designer and aircraft constructor in this matter. Rapidity of progress is essential and it can only be gained by cohesion of effort, lack of friction, and mutual understanding. The Service must remember that the aeroplane designer has to live and is not always merely chasing “X” with a slide rule; the constructor, that the soldier is not only pipe–clay and red tape and that there is sometimes method in his madness.

Abstract The article presents an innovative method that was verified in the field. It is aimed to improve the load bearing capacity of airfield pavements, which are one of the elements of the flight safety system. Airfield pavements protect the runway in case when the aircraft is taxiing beyond the runway. Moreover, they are also used to perform starting and landing operations of military aircraft. Due to this, they need to have an adequate load bearing capacity that ensures the safety of performing aircraft flights. Airports cannot afford to be shut down for a long time; thus, it is essential to look for efficient and fast solutions that could improve the load bearing capacity of airfield pavements. The authors suggested to apply geogrid immersed in natural airfield pavement.
