The functional-architectural model of aircrafts on-board I&amp;C systems with possibility for CN reconfiguration, as well as enhanced method for assuring the functional safety of aircrafts on-board I&amp;C systems on their design stage and a new method for assuring this feature during the operational stage of such systems, based on the proposed model and which consider the on-line criticality and reliability control results of certain elements and functional subsystems is proposed and discussed.</p>
