Nowadays aviation radio equipment is an important technical tool for solving various problems in the civil and military spheres related to flight safety and regularity. To ensure the effective use of aviation equipment for its functional purpose, it is usually necessary to develop and implement a functionally complete infrastructure of interconnected elements, which in particular include state regulatory bodies, enterprises that implement the stages of the life cycle of the equipment (design, manufacture, operation, and disposal), educational and research institutions and laboratories. During the use of the equipment for its functional purpose, situations arise when it is necessary to maintain and restore the performance of these devices. This task is implemented by carrying out maintenance and repairs in the relevant divisions of operating enterprises. Taking into account the large number of operated devices, the wide geographical location of centers of their use, the task of substantiating the infrastructure of repair centers for aviation radio equipment is urgent. This task was solved by developing a step-by-step methodology for calculating the efficiency indicators of the process of aviation radio equipment repair.
