Abstract

The structure of the mathematical models of objects, methods of approximation (interpolation) of their characteristics, the methods and means of identification should be agreed among themselves and form a single information technology, convenient to use, in particular, in aircraft simulators. Computational methods used in the development of models of aircraft simulators and other technical teaching aids, can be divided into General and specific. Common methods are well-known methods of computational mathematics that make up one of the most important topics in applied mathematics at all. They are implemented in software on the mainframe, the relevant programme «shells». In the enlarged form of information technology of identification consists of the following stages: baseline experimental and calculated data; primary processing and creation of the data array; designation of areas of approximation in spaces of arguments; the choice of method of approximation and implementation  of approximation; develop working algorithms; evaluation of accuracy. Identification usually requires creativity, nature study, and only in rare cases, it may be completely formalized. Iterative research are, inter alia, such as assigning areas of approximation, the choice of method of approximation, etc
