The offered model of radiowaves propagation of the unmanned aerial system data link is realizedin two stages: calculation of middle radius of coverage area and his further elaboration by geometricalmethods along the separate directions with the expressed relief inhomogeneities. Underestimationof this factor can be a reason of absence of receiving signal which leads to interruption of integrity of information,or can be an occasion of propagation of radiowaves beyond of destination area which createsa precondition of leaking or physical interception of information. The model allows to promote the levelof informative integrity, availability and safety of data exchange due to a removal of propagation of radiowavesout of setting. Also it promotes reduction of probability of leaking and physical interception of informationas well as retain of necessary level of availability and integrity of information
