The automation of the exploitation risks assessment of the navigation information system of air drones

The article presents the method of the quantitative assessment of the exploitation risk of the navigation information system of air drones. With this method, it's possible to measure the probability of the failure of the system without the development of the failure tree. The presented method provides the way to solve the problem of decreasing the level of the exploitation risks of the navigation information system of the air drone on the stage of the system engineering. Presented method is based on the new mathematical models of the components of the navigation information system with detailed representation of the critical failure state.
