Resumen
The aim of the study was to develop a model of the readiness and reliability of an aircraft to perform an air task. The applied research method uses quantitative statistical methods and Markov processes in order to create a mathematical algorithm to exploit a selected aircraft type. The paper presents a case study of the TS-11 ?Iskra? aircraft. The results show that even if the probability of being on stand-by is low, the tasks can be completed by operating the entire fleet properly.
