Aiming at the problems of aviation crash, such as suddenness, great loss, high search and rescue requirements, great difficulty, complex investigation procedures and far-reaching secondary hazards, unmanned aerial vehicle (UAV) equipment is used to assist the execution of accident search and rescue missions. Based on the advantages of UAV, such as safety and security, load diversity, flexibility, fast and efficient, and intelligent interpretation, combined with technology development and demand analysis, nine typical application scenarios of UAV in aviation crash search and rescue are analyzed. The results show that the analysis can provide reference for improving the scientific, information and intelligent level of aviation accident emergency rescue management.
