Aerospace Instrument-Making Annotation << Back THE TASK OF MANAGING SAFE LANDING AND FLIGHT ALONG NON-INTERSECTING ROUTES FOR GROUPS OF AIRCRAFT A.I. Eremin, D.A. Mihaylin, A.P. Moskalev, A.V. Roumakina The possibility of predicting the danger of group route flight of aircraft when they approach each other and a quantitative assessment of confidence in the continuation of landing under the influence of negative factors is considered. For the routing task of a group flight, the necessary and sufficient conditions for the non-intersection of routes are formulated while at the same time observing the criterion of the minimum total flight path of a given group of ground points. To control the safety of landing using fuzzy logic, the influence of wind disturbances, piloting errors, limited fuel supply and on-board equipment failures were taken into account. Keywords: group flight management, dynamic programming method, predictive risk function, crosswind, alarms. DOI: 10.25791/aviakosmos.05.2020.1155 Pp. 03-15.
