The presence of unmanned aerial vehicles in the airspace is affected by stimulating the development of aviation but also led to the creation of a new kind of threat. The variety of design and versatility of their applications made unmanned aerial vehicles widely available to all people. The number of flight incidents involving UAV was largely caused by failure to follow the rules of safe operation and the lack of experience of the operator. Due to the effects which may entail collision with an unmanned aircraft, aviation authorities and the users themselves take a series of measures aimed at their elimination.
