The ever-increasing requirements for aircraft control systems lead to their more complex structure and, consequently, synthesis. Thus, there is a need to develop and improve control algorithms that can meet these requirements. To develop control systems for high-precision aircraft, it is important to analyze how adaptive control systems are used. The paper examines the aircraft control system with one-parametric adaptation homing in the final section of the trajectory. The analysis of the test trajectory of the aircraft movement allowed us to establish the criteria for selecting the adaptation parameter. We comparatively analyzed the parameters, found a method to estimate their efficiency, and demonstrated the operation procedure of the adaptive system on a typical model of an aircraft moving in the atmosphere when homing in on a fixed target. The study gives the results of numerical simulation and shows the high efficiency of the method developed.
