Unmanned aerial vehicles have become widespread in various fields of activity. In this article, we propose an approach to choosing performance characteristics of a quadrocopter, which provide a possibility to solve emergency landing problems. The key target characteristics for such a device are substantiated. The calculation methodology assumes the selection of commercially available components with the appropriate characteristics. For this purpose, the eCalc software was used. In the second part of the work, we propose a mathematical model describing the quadrocopter movement in emergency situations. This model allows us to create algorithms for solving control problems in various emergency situations. For implementation the possibilities of MATLAB package were used. Numerical experiment is carried out to prove the efficiency of this approach.
