Information system for land registration state aircraft safety

The article is devoted to the conceptual approach to the organization and functioning of the information system of land registration of the security status of the aircraft. Modern means of registration have traditionally placed on board of the aircraft. This character of their placement does not guarantee the integrity of the information latched during catastrophic situations. The authors propose to duplicate critical information by means of terrestrial services. To this it should be a system of land registration of the security status of the aircraft. It is assumed that the system should include the following components (systems): airborne, ground and orbital. Onboard complex is none other than the terminal, which receives information about voice and crew talks about the technical parameters of aircraft. This information formed into blocks, which are periodically transmitted in the direction of orbital or terrestrial systems. Ground complex in conception is the information and telecommunications network arbitrary or any cellular structure, while between its two different nodes should be at least two independent transmission route. This network is designed for accumulation and translation of the board received information in accordance with the route of the vessel. Orbital complex plays the role of the reserve component. He is engaged in special situations, such as flying aircraft over the ocean space at a considerable distance from the coastline. Its main function should be considered as a signal relay on board the aircraft nearest node terrestrial component to the route of the vehicle. This article discusses two versions of interaction airborne and ground systems to form a complete picture of the information security of the aircraft is able to board the vehicle. The first option involves the transfer to the ground all the complex information stored on board when flying a regular route zone. This approach is equivalent to the current replication status information to a remote server. At the same time ground-based network resources are utilized not fully, but the network itself does not guarantee occurrence of congestion nodes with increasing intensity of transport flows in the areas of its service. The second option provides for a “reset” in each zone only the information that has been accumulated since the last exchange of airborne and ground systems. Then, all the previously transferred to the “land” data must be translated to another point “reset” in real time, are accumulated with the newly received information, and be ready to further advance over the network. This ground complex is not only responsible for the integrity of the data, but also for the reliability of their delivery to the final destination. Distributed databases with structural adaptation are the technological aspect of such a system of organization. Thus, the terrestrial infrastructure forms an information model of the motion of the aircraft in order to preserve all critical information.
