The main advantage of given technology is the ability to obtain and use in "real time" mode a number of important performances of aircraft equipments, metrics of organizational and technological processes etc. in the aircraft lifecycle management system.
The article outlines the theoretical approaches to the optimization of the geometrical parameters of flexible tanks for petroleum products taking into account the total length of the stitches on the top and bottom surfaces. The algorithm, mathematical models and optimization criterion to significantly (up to 20%) increase the efficiency of cutting the material of construction are proposed. On the basis of these curves are the formulas for determining the optimal height, length and width of the flexible container. The calculations are for the optimal sizes for example, flexible container with a capacity of 250 m3.
The basis of the proposed methodology is the evaluation of the barrier and physico-mechanical properties of structural polymeric material after the unilateral oil exposure at the alleged exploitation of the climatic region. Calculation of technical and economic efficiency methodology shows that savings of 360,000 rubles occur when testing the same polymer material with a petroleum product.
Highly informative method for determining the residual life of the compounds of collapsible oil pipelines on the actual condition of rubber O-rings is developed. Ratios and proposed formula for calculating the residual resource of quick couplings depending on the climatic region of operation are experimentally established.

In the article the analysis of engine turbine blades performance operation conditions influence is presented. As a result the factors, resulting in poor durability of the blades in operation, the characteristic defects of the turbine blades are determined and the conclusion on the necessity of applying a protective coating on them is made.
The challenge of improving the personnel policy of Russian civil aviation in the context of the main aviation specialties to ensure safety in today's realities air traffic. The definition the main problems of personnel policy, expressed in the lack and age restrictions flying staff, engineers, technicians and dispatchers of air traffic control.
Influence of unsymmetry of spectrum of the hindrance caused by inaccuracy of tuning of entrance filter is examined, on exactness of phase navigation determinations in a satellite radionavigation systems frequency-division channels.
Influence of replacement of a phase of a signal on its digital equivalent in the form of a time interval between zero transitions of a basic signal and mix of a signal and hindrance to the accuracy of digital systems of phase synchronization of means of communication and navigation is considered.
Article is devoted to detection and identification of refusals of governing bodies like "withdrawal and a klineniye" in ideal statement (the atmosphere - not indignant, sensors - ideal). Relevance of consideration of the matters is caused by a problem of deficiency of time for detection, identification and parrying of refusals of AT, in particular a control system, as systems of the most sensitive to refusals of its functional elements. In article the original technique of identification of refusals is stated, the results of modeling illustrating high precision of identification of refusal of an elevator are given.
One of the objectives of the management of infrastructure facilities is to ensure efficient evacuation in an emergency. The problem of the evacuation is related to the heterogeneity of data, its’ large volume, the loss of part of the information infrastructure under the influence of destructive factors. The concept design of the automated evacuation control system based on system engineering is considered. It involves the use of a systematic approach, modern information technologies, as well as simulation. The actuality of the use of technology solutions for big data management tasks in real time is proved. As a tool for distributed processing, cluster prototype with low power consumption computers is proposed.
