Recently, with the advent of the 4th industrial era, unmanned aerial vehicles, which were mainly used in limited areas such as the military area, have expanded to the civilian area. That is, in the early stage of development, unmanned aerial vehicles were mainly used for military purposes, but recently, their utilization for various purposes such as imaging, agriculture, and leisure is rapidly increasing.
The purpose of this study is to analyze the accidents of factors that threaten safety in the operation of unmanned aerial vehicles and to suggest ways to improve aviation safety awareness of unmanned aerial vehicles. Therefore, this study analyzed accidents by applying SHELL MODEL to a total of 10 accident investigation reports reported to the Accident Investigation Committee. It was analyzed that errors caused by human factors such as insufficient confirmation, errors in judgment due to insufficient awareness of the situation by the pilot, non-compliance and lack of compliance with the pilot's compliance, lack of communication between the pilot and visual monitor, and insufficient safety supervision by government agencies were analyzed.
Based on the SHELL MODEL analysis results, a survey was conducted on aviation safety awareness targeting workers and non-workers. The input data were analyzed according to the purpose of the study using SPSS/WIN 28.0, and statistical techniques such as factor analysis, reliability analysis, correlation analysis, and multiple regression analysis were used.
The following conclusions were obtained through the statistical analysis of aviation safety awareness of workers and non-workers.
(1) According to the socio-demographic characteristics of workers, there was a statically significant difference in aviation safety awareness according to flight time and flight experience. Drone flight time was 5.00 over 500 hours and less than 700 hours. In terms of flight experience, 2 years or more and less than 4 years accounted for the highest share of 5.00.
(2) There was a significant difference in the non-worker's perception of aviation safety awareness improvement according to age and flight experience. Aviation safety awareness was the highest at 5.00 from 40s to 60s, and drone flight experience was the highest at 5.00 for more than 6 months and less than 2 years.
(3) Aviation safety awareness has a positive (+) effect on improving aviation safety awareness. In other words, if the aviation safety awareness of workers and non-workers is high, the improvement of aviation safety awareness also increases.
Next, the following conclusions were obtained through detailed questionnaire analysis (type of accident, unauthorized flight, unqualified flight) of workers and non-workers' aviation safety awareness.
Among the two groups in the questionnaire on accident type, workers answered that it was an unauthorized, unapproved flight by an unqualified person, and non-workers answered inexperienced piloting as the highest type of accident.
During the questionnaire on ineligible flight, both groups responded with some level of ineligible flight experience. Non-employees had at least one unqualified flight experience, and employees had a lower level of unqualified flight experience.Among the surveys on unauthorized flights, 62% of workers experienced unauthorized flights at least once, and 71% of non-workers experienced unauthorized flights at least once.
