Background. The object of the research is the control system of safe following motion of two aircrafts. The subject of the research is the methods of ptimal flight control. The article is aimed at reproduction of human actions through quantitative estimation of the current risk in movement and in subsequent rearrangmenet of the control system by the example of aircraft’s entering the echelon on the back track.
Materials and methods. The author formulated a problem taking into account an integral criterion of motion safety and a synthesis of rules of optimal aircrafts’ fol-lowing movement control on the basis of dynamic programming.
Results. The result of the system work is maintaining a certain safe distance between two aircrafts despite the sudden deceleration of an aircraft flying in front. The author obtained the results confirming the possibility of automatic security control performed by the control tower service.
Conclusions. On the basis of the research carried out it is possible to make the following conclusions. 1. The author revealed optimal security control of the following motion of aircrafts in the form of an algorithm, having in general case on its input the coordinates of aircraft’s lateral motion X₁ and X₂, the coordinates Y₁ and Z of progressive and lateral motion of the second aircraft, and the velocities V₁ and V₂ of progressive and lateral motion of both aircrafts. 2. The synthesized system may be used for automatic prompting a pilot or control tower service on alert in case of dangerous closing in of two aircrafts while entering the echelon.
