Abstract. The article presents the experience of technical operation of the air data inertial reference system (ADIRS) both on real aircraft in airlines and on a procedure trainer during the “Simulator training” practice at a university. The features of the ADIRS construction are considered, its central role as the main source of flight and navigation information in the composition of the integrated onboard complex is shown. The main method of technical operation of the system under consideration is “on-condition” operation, i.e. operation until a dangerous failure occurs that can affect flight safety.
Through full-scale experiments based on the analysis of the system performance in real conditions typical failures are shown, emergency situations and possibility of system reconfiguration are considered. In the presence of a procedure trainer it is possible through experiments to study the features of the system operation, to develop a methodology for identifying and eliminating some failures.
The article proposes to use a continuous training system, consisting of three stages, when training aviation specialists. The first stage is a discussion of the construction features, the experience of technical operation of the systems under study at a local scientific and practical conference. The second is performing practical tasks for the systems under study on a procedure trainer. The third is conducting the technical operation work on the real aircraft systems.
