Description

The invention relates to the field of control and can be used for direct flight control both in the area of the airfield and on the routes.

When controlling aircraft in the area of the aerodrome, which is performed by the flight management group, the task is to identify potential conflict situations (PCS). It can be addressed at various stages of air traffic control. In this regard, certain methods of analysis of PCD can be used. So, at the stages of long-term and preliminary planning, it is advisable to take into account changes in the degree of conflict of air traffic over the expected number of ACLs when the intensity of air traffic changes. Therefore, in the process of current planning and direct air traffic control (ATC), there is a need to identify conflicting pairs or groups of aircraft (LA) with an assessment of the parameters characterizing the degree of danger of the aircraft, or the time remaining before the approach of a dangerous approach.

There is a method of controlling the air traffic of aircraft by analyzing PKS (Tarasov VG Fundamentals of the theory of automated control systems. - M.: VVIA named after N.E. Zhukovsky, 1988. - 438 pp.), Which was developed for automated warning systems of PKS on based on the concept of a database containing and supporting a dynamic information model of the air situation. The essence of the known method consists in the fact that the information on the movement and location of aircraft, obtained by means of a radar landing station (RPS), is sent to the command and control station, where using remote landing indicators (VISP) the flight control group (hydraulic fracturing) detects aircraft . But when detecting PCS, frac persons spend uneven time intervals on aircraft maintenance, which ultimately leads to a decrease in the throughput of the air traffic control system, i.e. does not ensure the rational use of airspace. This method, although it provides information-logical modeling of the air situation for the task of analyzing the ACL, however, this control method has a number of significant drawbacks:

the aircraft motion model corresponding to this method was developed for airways;

the use of this model for the analysis of ACL in the area of the aerodrome is not possible due to the significant difference in the kinematic and dynamic characteristics of the movement of the aircraft in the area of the aerodrome and on the route;

the safety area in this model is represented by a horizontal figure in the form of a circle;

the known method provides the elimination of the ACL only by changing the module of the velocity vector of the aircraft and does not take into account possible ways of resolving the ACL by controlling the course of the aircraft, as well as maneuvering in height;

the known method does not allow to identify the type of arising PKC;

the known method does not take into account the uncertainty of the location of the aircraft, due to the errors of the meters of the parameters of movement of the aircraft.

The technical result of the invention is to increase the throughput of the aerodrome area without reducing the level of flight safety of aircraft with direct air traffic control.

The essence of the invention lies in the fact that in the method of controlling the air traffic of aircraft in the area of the aerodrome, which consists in obtaining information about the location of the aircraft in space using the RCS, displaying information on the AISP, analyzing the information by the flight management group and deciding on the control of the aircraft, according to According to the invention, information from the RSP also arrives at a personal electronic computer (PC) with a software and mathematical software unit (PMO) that performs the functions of ation of control actions and the formation of the graphic display on the PC monitor the air situation to respond to emerging and foreseeable conflict between flying aircraft. In this case, the safety area around the aircraft is represented in the form of an ellipsoid of revolution, with the center coinciding with the geometric center of the aircraft and the axes corresponding to separation standards in the area of the aerodrome.

The drawing shows a block diagram of the implementation of the proposed method for identifying potential conflict situations in the area of the aerodrome with direct flight control. This scheme includes: aircraft (LA) - 1; radar landing system (RSP) - 2; remote indicators of the landing system (VISP) - 3; personal electronic computer (PC) - 6; software and mathematical support unit (PMO) - 5; flight management group (EMG) - 4.

The proposed method for controlling the air traffic of aircraft is implemented as follows.

Information about the air situation in the area of the aerodrome is determined by the CPD. Evaluation of the parameters of the movement of the aircraft and forecasting the ICS is carried out by the PMO unit. On the PC screen, the real air situation is formed and displayed taking into account emerging conflict situations. The structure of the PMO includes a database of typical potential conflict situations arising from the direct control of air traffic in the area of the aerodrome; a system for generating control actions, which, depending on the information arriving at the PMO input, gives information about the location of the aircraft control signals; a set of mathematical models of the aircraft’s movement, which allows predicting the aircraft’s movement, in which the safety area around the aircraft is represented as an ellipsoid of revolution, with the center coinciding with the geometric center of the aircraft and axes corresponding to separation standards in the aerodrome area, and also taking into account the uncertainty area of the aircraft’s location; graphic array formation system. Based on the assessment and prediction of the position of the aircraft during movement along the lines of a given path in the area of the aerodrome, the PMO unit forms on the monitor screen a real air situation in the area of the aerodrome with the display of conflict and pre-conflict situations.

The application of the proposed method will reduce the time of detecting ACS by persons of the flight management group, which will lead to an increase in the throughput of the aerodrome flight control system without compromising flight safety, and it is most rational to distribute airspace between its consumers. And taking into account the area of uncertainty of the location of the aircraft allows you to most accurately determine the time of occurrence of the ACS.
