Abstract

Background/Objectives: This study was conducted to identify hazards that may arise from operating small Unmanned Aerial Vehicles (UAV) in non-control areas.

Methods: This study identified the types of accidents that could be caused in the operation of the UAV based on the International Civil Aviation Organization accident type classification system. This study analyzed the hazard factors related to reliability according to the life cycle of each small UAV system and the hazard factors related to the operator's flight proficiency.

Findings: First, Product based structure of the minimum flight system for each mission model was derived by supposing UAV classes C2 and C3 in order for the realistic mission models of small UAVs, such as facility diagnosis monitoring, collecting evidence of traffic violations and event venue photography.

Second, the types of accidents that can be caused by each mission model are commonly identified as Loss of control in-flight, Fire-non impact, Fire-post impact, Power plant failure, Control flight into terrain, Bird strike, Mid-air collision, Navigation error, and Loss of lifting condition enroute.

Third, According to each mission model, the Bow-Tie model of the Ministry of Land, Infrastructure and Transport was derived that includes all hazardous events by hazard factors, causal events, safety mechanisms, defense mechanisms, potential consequences, and potential consequences severity.

Improvements/Applications: These results prove that, for safety, safety indicators should be set and managed for hazards that may be caused in the operation of small UAVs.
