This paper is focused on creation, accuracy and simulation of 2-parameter control of a mathematical model for motion of aircraft in a flying simulator. We are discussing many of important advances in applied aircraft modeling. Modelling on various computer architectures (central, parallel, distributed) has an impact on a structure of a simulator system of aircraft. The way of description of a numerical method and its accuracy, a shared memory system and a distributed memory system, is an important part. Necessary accuracy of implemented simulation methods, an analytical approach to definition of mathematical models, and corresponding simulation implementation architecttures are presented in the article.
