The problems of possible changes in the shape of aircraft in the process of movement are considered. Approaches to the detection of deformations in the process of motion are proposed. The efficiency of using such generalized parameters as dynamic coefficients is shown. A system is obtained in the deviations of the motion parameters of undeformed and deformed bodies and formulas are derived for changes in dynamic coefficients. The possibility of using not only traditional identification approaches, but also new methods of data mining, was noted, including the most informative indicators of state for the studied deformed bodies were determined. The ability to assess the presence of deformations based on calculations of indicators based on the results of measurements of angular velocities, inclination of the trajectory and angles of attack is shown on multiple simulations of the motion of undeformed and deformed bodies. Effective ways of storing the reference information are proposed taking into account analyzes of the characteristics of the bodies under investigation for the presence of critical sections, in which it is proposed to estimate the acceptable step enlargement based on the analysis of the Pareto front relative derivative (increment) of the function.
