Abstract

Background/Objectives: The purpose of the study is to suggest some measures for auto-rotation function education that helicopters can be safely land on the ground in the event of engine failure during the flight.
Methods/Statistical analysis: The data is based on an analysis of auto-rotation flight accidents that have occurred since 1982 with a focus on the single engine helicopter model 500d operated by Korea's Army Aviation. Statistical data analyzed the causes of accidents during the accident of Army Aviation are categorized as human, physical and environmental errors. In this study, only auto-rotation flight accidents were extracted and analyzed.
Findings: In this paper, we investigated and analyzed the auto-rotation flight accident of 500d helicopter and found that most of the accident causes were human error in the final landing stage and suggested the following four improvement measures. First, it is to strengthen theoretical education, such as calculating altitude-speed flow chart for auto-rotation flight, and fully acquire situation-specific flight technology to cope with external environment (airplane speed, wind, altitude, air density, temperature, etc.). Second, it is to establish an effective flight training system for VR (Virtual Reality) and AR (Augmented Reality) linked with the fourth industry. Third, it is to improve the overall flight education system through investment in equipment and facilities such as helicopter flight simulators. Finally, it is to do continuous efforts are made to improve pilot safety mind and comply with regulations and procedures to remove human error.
Improvements/Applications: The results of this study are expected to greatly contribute to the improvement of pilot training and flight training systems for aviation training institutions and flight units.
