In article is offered the methodic of definition quantity of measured parameters electronic equipment for an estimation of its engineering condition with the set probability. The essence of a methodic consists in formalization process definition of quantity
measured parameters of the sample of aviation technique. Process formalization is ensured with introduction of concept of the importance each parameter. The quantitative estimation of the importance parameters was determined by means of introduction factors of the importance. The method expert estimations were applied to determination factors of the importance parameters. The offered technique is applied on an example operation of radio station R-832M.
