abstract This article presents the results of analyses of aircraft emergency state changes during flight, which will help refine the models of aircraft technical operation processes at airports within a given airline network to enable continued flight. Therefore, in-flight aircraft state changes are eliminated because equipment failures (i.e. aircraft state changes) occur at each stage of the aircraft's flight, requiring fault resolution. Hence, the aircraft's transition through the states during a single flight is presented in the form of a graph. The operational management circuit of the airline's aircraft fleet is represented as a sequence of flights, each consisting of a series of segments between airports within the airline's network within the calendar timeframe of the aircraft's presence in that circuit. The model allows assessment of the aircraft's ability to recover, if necessary, at airports within the airline's network, utilizing the probabilistic and temporal characteristics of the recovery processes employed by airports, which pose a risk of flight delays. Recovery time must be considered to assess the probability and duration of flight delays.
