Research of the cooperation technology between the air traffic control service and the aerodrome service

The article considers the process of cooperation between the ATC and airport operation services. The analysis considers the procedures of cooperation while inspecting a runway before performing flights, aircraft departure and arrival that encompass the entire range of coordinated operations. For each procedure, the costs of aircraft delays are calculated. The assessment was carried out by synthesizing the chronology of services cooperation in real conditions. On the basis of the collected data flowcharts of services cooperation to ensure flights of an airport and the ATM services were built. To provide a visual comparison of the existing and proposed model sof services cooperation the networks of services cooperation were built based on the mathematical model of the graphic chart. The operation network establishes the sequence of events to provide departure of one aircraft operating a scheduled flight of an airline. Within the given study the ATC service and the aerodrome service are involved to ensure a departure. Cooperation between the operation and dispatch service of the airport and an aircraft crew is conditional because in this case they do not impact the technology of cooperation. The network is a particular set of dots(summits)interconnected by lines (links). In the case of our study, circles are events (performed work). Directional segments (lines) are work connecting events to each other. While assessing the process of cooperation during arrival and departure, two cases were considered: the runway is occupied or clear.The runway could be occupied for different reasons: available vehicles, people, animals or flocks of birds on the runway. The study of the cooperation technology was carried out for 12 monthsof making scheduled flights at Zhukovsky and Ostafievo airports on the basis of every day flight plans.
