TERENTEV The article discusses the features of the methodological approach to the probabilistic analysis of the effectiveness of test objects. The use of probability and quantiles as criteria is a more objective and convenient way of making decisions when creating aviation equipment compared to the multicriteria problem of parametric optimization of a set of basic tactical and technical characteristics. During the operation of the system in real time, the need arises to apply the techniques used to calculate probabilistic criteria for the implementation of the target function. The article presents a method for probabilistic analysis of the efficiency of an object at the stage of ground testing, performed in an automated form using the Mathcad environment. An objective assessment of the effectiveness of unmanned aerial vehicles contributes to solving the priority task in creating promising unmanned aircraft and is one of the ways to improve the combat potential of the Armed Forces when using modern Russian unmanned aerial vehicles as a new highprecision type of military equipment.
