The paper deals with engineering and cost specifications of Instrument Landing System (ILS) and GBAS Approach Service Type (GAST), which are used for precision approach in civil aviation. In the process of gradually replacing the ILS system with the GAST system, it is advisable to briefly consider all the factors that affect the decision regarding the scope and timing of the GAST implementation. The paper briefly deals with technical characteristics of systems, destabilizing effects on the systems accuracy, vulnerability to jamming and spoofing, and future benefits. Main advantages and drawbacks of the navigational systems are considered. The use of GAST-D (category II and III) gives an opportunity to change air traffic management procedures in order to increase runway throughput, which is important for busy airports, especially in low visibility conditions. Cost analysis includes only some items: equipment cost, airfield works connected with installation, maintenance, and flight inspection. Some examples from airports “Zhulyany” and “Boryspil” (Ukraine) are given.
