The influence of the type of distribution of measurement error and measurement uncertainty on the reliability of the multiparameter measurement testing is studied. Indicators of testing reliability include the probability of a control error of type 2 (P2), as well as the risk of the customer Rз and the risk of the manufacturer Rп. These control reliability indicators were calculated for different values of measurement uncertainty. The study was performed using the Monte Carlo method (imitation modelling). Three models of measurement error distribution were used: normal distribution, triangular (Simpson) distribution, uniform distribution. The results obtained allow us to establish the measurement uncertainty that provides the required risk of the customer (or another indicator of reliability). The following was established. For the symmetric law of error distribution, the highest estimates of the reliability indicators take place with a uniform distribution of the measurement error. The probability of P2 is weakly dependent on the number of controlled parameters and the type of distribution of the measurement error, but it significantly depends on the accuracy of measurements. The customer's risk depends significantly on both the number of controlled parameters and the accuracy of measurements during control.

Bases of use of fiber optical paths as indicators of destructions are described at durability tests of aviadesigns. Recommendations at the choice of optical paths and are given to ways of their installation. Principles of construction of the equipment for registration of destruction of indiczlors are considered. Prospects of creation of the distributed fiber-optical gauges of deformations and destructions are noted. In this paper the task of searching metal objects in people cloth is soled. System consists from five single winding (frame) for creation required direction diagram. Using radio frequency band allows to combine transceiving channels, to reduce weight and size, to increase sensitivity, noise-immunity, to improve energy features.
