UDC 625.717:725.394(043.2) G. M. Agieieva, PhD, A. Burchak, Т. S. Sukach (National Aviation University, Ukraine) Air traffic control tower: changings of initial options Annotation: There are given there are given the results of research of world practice of airports reconstruction, in particular, the air traffic control. Over the time researched objects had lost their option of high-rise dominant building airports, but they had gotten new options in public buildings. The increasing importance of the air transport in World economy rises up the requirements to the airports, particularly to the quality and services which are provided. The demand for new buildings, modern airport buildings, the infrastructure objects and additional service, which meet current standards, are constantly growing. Airport development is not only building the new airport and reconstruction the existing ones buildings and constructions, this is also decommissioning and dismantling of individual objects. These can be the landing strips, terminal buildings (Khabarovsk, Russia), command-dispatching posts (Hartsfield-Jackson Atlanta International Airport, USA), etc. Social, political and economy changes in society are cause of non existing the big number of the airports (for example Donetsk, Ukraine; Tempelhof, Germany; Stapleton International Airport, USA). Some of them are being rebuilt and some of them are replaced with residential arrays, sport and trade centers, industrial enterprises; military airports are acquiring new functions, etc. Individual buildings are getting new options [2]. We will explore this on examples by several buildings of air traffic control tower (referred as - ATC) - high- rise dominant building airports. A. Stapleton International Airport, Denver, Colorado, USA. During 1929 – 1995 this airport was the main airport in Denver, Colorado [3]. The area of the airport was 19 sq.km, also there were six runways which provided air transportation; at Denver airport passengers were served by five terminals (rice.1, a). The control over ground handling of aircraft was carried out by the controllers of the ATC, located in a 12-storey building (fig.2, а). 21.23
