abstract="The article presents a semiotic model of &quot;aircraft conditions&quot; in flight and multilevel structures of an aircraft. The hierarchical structure of abstract models is divided into blocks and levels that make them more compact by applying a mathematical apparatus corresponding to the goals sated. The above models were tested on the basis of statistical data on TU-154 aircraft failures for 10 years. Various aircraft functional system failures in flight were examined. The state of the aircraft is identified by normative indicators recorded in the &quot;Aircraft Technical Operation Manual&quot;.   Keywords:     Aircraft; failure; faulty condition; flight delay; flight safety; management<p /> <p>Language: en</p>",
