The article analyzes the main principles of protection of settlements, industrial facilities and special territories against forest and landscape fires. Approaches to the organization of effective protection are considered, including close cooperation with local authorities, creation of firefighting teams and use of available firefighting forces and means. Special attention is given to the use of small and medium sized aircrafts, including helicopters with water dropping devices, as well as specialized aircraft, such as IL-76 and BE-200, for active firefighting. One of the promising technologies is the use of unmanned aerial systems (UAS), but their widespread implementation is hampered by the lack of a regulatory framework and insufficient study of the parameters of delivery of extinguishing agents such as water. This paper presents calculations to determine the amount of extinguishing agent required for firefighting with UAVs and provides recommendations for their optimization. It also discusses the challenges associated with improving the efficiency of water delivery and the possibility of using water additives to increase extinguishing performance. The results presented can serve as a basis for further development of firefighting technologies using UAS
