Objective: to map the competencies developed in training strategies for air transport practices for patients, in the face of emergency situations and disasters involving chemical, biological, radiological and nuclear (CBRN) agents. Method: this is a scoping review structured in accordance with the JBI and Preferred Reporting Items for Systematic reviews and Metanalyses extension for Scoping Reviews recommendations. The study was carried out in five stages: search for sources in 17 databases, an information portal and two repositories of gray literature, using 125 DeCS, MeSH and Emtree descriptors, without temporal and idiomatic clipping; selection; critical reading of the texts selected by two double-blind reviewers; summary of results and presentation of mapped competencies. Results: a total of 878 studies were analyzed, of which 18 composed the sample. In all, 11 competencies were mapped, with emphasis on the technical training domain. Competencies refer especially to technical-scientific knowledge in disaster situations involving CBRN agents and the safety of patients and professionals involved. Conclusion: the operationalization of artifices to improve qualification processes based on competencies proved to be strategic to increase the quality and safety of patient air transport practices. The approach of the sources on specific aspects of the particularities of practices related to emergencies and disasters involving CBRN agents in training/training processes demonstrates the academic effort to promote the reduction of the risk of these events when, in due course, civil and military institutions and their health operators are activated.
