The paper discloses the method for evaluation of service lifetime of on board avionic hydrostatic drives on the background of information acquired from human independent flight control devices on the basis of description how the structural parameters of the system subject to alterations over the equipment lifetime. The description of structural parameters related to the hydrostatic drives takes advantage of these data from the human-independent flight control devices that have not been used so far and establishes correlation between these data and the measurement signals that are typical for the drives. Evaluation of the service lifetime employed by the presented method consists in comparison between the values for actual structural parameters and adequate threshold limits under provision that specific parameters affecting the process of predicted lifetime evaluation as well as describing the technical condition of the devices are mutually independent. Identification of structural parameters attributable to avionic hydrostatic drives was carried out on the basis of information that can be acquired from human-independent flight control devices. The theoretical backgrounds for the proposed method related to assessment of technical condition of an avionic hydrostatic drive and evaluation of its expected lifetime on the background of information acquired from the human-independent flight control devices are presented, as well as measurement data are listed whereas the data had been acquired from human-independent flight control devices and they refer to structural parameters of avionic hydrostatic drives for two types of aircrafts that are operated by Polish Air Forces.
