Abstract. This article discusses the analysis of technical means of the airport’s air navigation system based on modern methods. The main expected functional changes to aircraft ATM capabilities from now until 2025 onwards include support for 4D trajectories and special approach types with optimized curved and offset trajectories. A promising tool for solving such problems is currently the use of multispectral surveillance systems that use both signals from radar and optoelectronic means in the visible and infrared ranges.

Keywords: air navigation, trajectory, radar, control room, surveillance system.
