COORDINATED MANAGEMENT OF AIRCRAFT DEPARTURES TO ENSURE THE SAFETY OF THEIR MOVEMENT AT TRANSPORT HUB

Abstract

The task is to coordinate the timing of departure from different airports of a large number of aircraft in order to eliminate cases of their dangerous approach in busy transport hub of a group flight. The conflict management function involves reducing the risk of an aircraft colliding with a source of danger to an acceptable level. A conflict situation is any situation involving an aircraft and a source of danger in which existing separation minima may be violated. The formulation of the problem of optimizing the delay time in the departure of aircraft when they approach at transport hubs is formulated and its solution is proposed on the basis of multiplicative convolution according to the criterion of maximum passenger comfort. It is required to form a single criterion for passenger comfort during takeoff and in flight itself, as well as to propose an algorithm for optimizing the departure delay times of a group of aircraft. When assessing comfort, penalty functions for delay in departure, the risk of unsafe approach of ships at transport hubs, and the factor of undesirable maneuvering when changing the flight level and flight speed are taken into account. An algorithm has been developed for the optimal four-alternative assignment of the delay time in the departure of each aircraft, taking into account the parameters of its approach to other aircraft. The examples of calculation and the results of comparing the optimal solution with the known approach are given. A gain has been established in significantly reducing the duration of the “conflict rapprochement”.
