Aerospace Instrument-Making Annotation << Back Way of association in the complex of the precisely-flight navigating equipment of aircrafts. V.E. Ksenofontov The possible direction of modernization of precisely-flight navigating complexes of planes of military-transport distant aircraft and helicopters due to the introduction of an additional contour of correction based on functional association of the onboard navigating equipment with the equipment of interplane navigation and communication between aircrafts is considered. Efficiency of functioning of a complex with an additional contour of correction in conditions of complex navigating conditions with application of methods оf an evaluation and diagnosing on the basis of application of dual and multilevel discrete models of its conditions is investigated.
