Abstract. As part of many specialized analog computers (SAVM) designed to simulate and
simulate the flight of aircraft, there are a number of electromechanical units and systems (integrating,
positional, instrument tracking systems, etc.), whose natural frequencies of oscillation should be at
least an order of magnitude higher than the frequency of change of the variables reproduced by them
in order to increase accuracy of modeling. In this regard, when designing a joint venture, it is
necessary to know the dynamic characteristics of the object, on the basis of which the technical
conditions for the manufacture of these blocks are developed. This article describes a technique for
obtaining the dynamic characteristics of the aircraft using the main control board (OPU).

Keywords: aircraft movement, dynamic characteristics, main control board, simulation
accuracy.
