Objectives: Possibilities of using drones in the ecological safety system. Methods: The main purpose of the research conducted in the form of a questionnaire was to get the respondents' opinions on the usefulness of unmanned aerial vehicles (drones) to support the performance of official tasks. (The method of a diagnostic survey with the use of a questionnaire). Results: The collected research material showed that the UAVs are useful to carrying out tasks related to environmental protection. The main recommendations for usefulness of drones in the surveyed group of respondents from individual forest districts were as follows: 1) performing tasks related to fire protection; 2) making cartographic materials, inventory of damages caused by abiotic and biotic factors; 3) used to fight forest pests 4) missing persons searching; 5) detection of illegal dumps; 6) animals inventory; 7) water courses beaver dams monitoring; 8) forest health condition assessment and monitoring; 9) the possibility of quick localization of fires in hard-to-reach places; 10) UAV equipped with thermal camera would help in monitoring (animals tracking); 11) tourist traffic monitoring. Conclusions: The collected research material shows that UAVs should be used by services and state authorities that perform tasks related to environmental protection. The results of the surveyed group of UAV operators show that drones would be useful in "tracking" illegal garbage dumps. Public services and bodies should use UAVs to monitor illegal garbage dumps. According to the surveyed group, there should be higher fines for throwing waste (garbage) in prohibited areas.

The paper presents selected issues concerning alternative power sources and propulsion systems meant for unmanned aerial vehicles (UAVs). The implementation of new propulsions in aviation is a laborious and long-term process, mostly due to safety and economical restrictions and requirements. Broadly, exploited solutions known from automotive industry may serve as a basis for development in aerospace technology, but cannot be applied without considering specific technical aspects (related to aircraft technology and flying objects physics). These aspects are mentioned in the text and some issues concerning suitability of types of aircraft are described. The paper presented contains a review of research on non-conventional propulsion systems for UAVs, conducted in Rzeszow University of Technology. Selected results of the research 􀣓 the fuel cell and the solar-cell UAVs and the aerial hybrid-electric drive test stand are shown in adequate pictures. The small-unmanned flying objects seem to be an accurate basis for such research. They allow reducing costs and improving safety in comparison to full-scale manned aircraft. They are also much quicker in manufacturing and easier to maintain and repair. Moreover, due to their various applications they may comprise the target market for this kind of propulsions. In particular, the issues of parallel hybrid-electric propulsions, fuel cell and solar-cell-assisted systems with appropriate examples are mentioned in the paper..
