Not only in Korea, but also in other countries, most helicopter accidents occur at low altitude. Analysis on accidents data collected both in Korea and other countries has brought two conclusions. Firstly, helicopter operations during the night hours carries a high risk. Secondly, the most common cause of night hour operations is loss of control due to the flight illusion. As an operation relying on a night vision in particular has a very high accident hazard, accompanying instruments such as NVG are ought to be provided. Hence, a thorough preparation and inspection on missions for night forest fire extinguishing should be required and perfect guidelines/road maps and enough training programs for the operation should be provided before the engagement in missions.

In this paper, the activities of North America to enhance the flight safety of helicopter were introduced. In North America, by 2009, 49% of worldwide civil helicopters are in operation. The development trends of North America to enhance the flight safety of helicopter are expected to have a significant impact to the other helicopter operating areas. The analysis of the case of Gulf of Mexico where large fleet of Helicopter in operations, FAA's NextGen program, and the Canadian plan to comply with the ICAO's Aviation System Block Upgrades plan shows the direction of helicopter avionic development for enhancing the flight safety of helicopter.

In this paper, We explain the development of helicopter avation information system which provides the current location and other pre-saved informations in order to guarantee the safe aviation. The system we developed has the functions such as displaying digital map data and current location, route planning, displaying the rate of deviation, calculating and displaying the cross sectional view through the route and providing a real-time speed, heading and other informations. In this system, we use GPS to get the current location, made the 1:250,000 digital map to display the current location and made the cross sectional view from the DEM(Digital Elevation Mode)) data to help safe aviation. This system provides many kinds of route setting methods by using UTM coordinates, Lati. Longi, coordinates, database of heliport location, scanned map, etc., and displaying the heading and distance. Moreover, it also has a characteristic of providing a consistent user interface.

EMSS is the organic system offering quick and efficient transfer and treatment for those who need an emergency service. For EMS aviation operation is the important transportation for the common benefits. There are several types of aviation operation. Among the different types of the operations, helicopter operation is very common because it is free from any locations. Notwithstanding the benefit, various types of EMS helicopter accidents and incidents are occurred because of its poor operation condition. In South Korea, even though so much effort was put to decrease the accidents rates, there are still many accidents happening by fire helicopters and the forest service helicopters. Therefore, in order to regularize the EMSH operation, measures for the aviation safety have to be prepared. This research is, related to the EMSH, focused on the suggestion of safety measure for the EMSH in Korea based on the accidents analysis in various countries.

최근 5년간 발생한 국적 항공기 사고 23건 중 헬기사고가 16건으로 전체 항공사고의 70%를 차지한다. 현재 국내에서 고정익 항공기 549대, 회전익 항공기 186대가 각각 운영(군 경찰 보유헬기 제외)되고 있음을 감안하면 회전익 항공기 사고가 훨씬 높은 편이며, 고정익 항공기 가동시간에 비하여 가동률이 매우 낮은 회전익 항공기를 고려하면 비행시간당 항공기 사고 비율은 회전익 항공기가 월등하게 높은 편이다. 또한 고정익 항공기의 평균기령은 10.9년인데 비하여 산림항공본부를 비롯한 헬기운영업체에서 운영 중인 회전익 항공기의 평균기령은 18.9년으로 회전익 항공기가 전체적으로 노후화 되어 있으나, 국적항공사에 운영 중인 노후 항공기 관리프로그램을 회전익 항공기 운영사에서는 운영하지 않고 있다. 따라서 본 연구를 통하여 노후 항공기 운영현황을 검토하여 노후 회전익 항공기 운영기준을 수립하고 노후 회전익 항공기의 정비프로그램을 정립하여 회전익 항공기의 지속감항성을 확보할 수 있는 방안과 수명주기 설정을 마련하고자 한다.

Korea's HEMS are mainly operated during the week, but they are pushing for 24-hour operations. This study has made an overall comparison and review of helicopter safety management that should be accompanied to this end. For research purposes, helicopter regulations and helicopter accident statistics were analyzed, with a high accident rate associated with pilot error and night flight. It was proposed that future preparations would require reinforcement of laws and regulations, reinforcement of pilots' night training, and introduction of training and preflight risk assessments. This study will provide a direction for future helicopter safety. This study will provide for future direction of helicopter safety research.
