2016, in total 53 corporations operate 160 aircraft. Since 2000, 52 accidents occurred in these corporations. This number takes 20.2% out of in total 257 accidents. Especially in 2016, in two(2) accidents, two(2) aircraft and people onboard were damaged. According to accident reports of aircraft using service, in most cases actions against common sense were connected to accidents. This means that attentions of managers or pilot would have protected accidents. On the basis of such background, this research analyses accidents cases of corporations operating aircraft by utilizing ahp. According to this anlysis, unlike scheduled and unscheduled airlines, pilots in command (0.109) and assisting crew (0.105) in Liveware have taken the most importance. Operational procedure (0.100) in Software and a controlling system (0.086) in Hardware have shown the second most importance. This result demonstrates that in case of corporations operating aircraft require safety management at different level than airlines.

To achieve designed quality and reliability from R&D to force integration, an establishment of precise and distinct specifications and standards are required. However, the recent process of R&D standardization on defense acquisition system, has brought plenty of corrections on specifications and standards that may cause not only difficulties to production line and retardation to the military forces, but also a degradation of provided weapon systems. Therefore, a technical review should be performed by the developer, the producer, and the client, establishing the standard that include mass production requirements as well as clients' requirements. This paper propose a specified solution on process of R&D standardization, by applying a substantial FCA(Functional Configuration Audit) and PCA(Physical Configuration Audit) which implies participation of related agencies. By the improved PCA, 2,023 corrections on 74 types of QAR(Quality Assurance Requirement)s and 12,715 corrections on drawings are identified.

The SBD systems have made it possible that all boarding procedures are completed by passengers. With the SBD, air tickets can be issued and baggage can be consigned without the help of airline officers. This way, the SBD can improve the passenger circulation speed as well as decrease the time for passengers to wait for check-in, which is connected to the reduction of airlines' operaitonal costs. However, given that the SBD is a new technology, it has potentials to be used as a tool for air terrorism. This study purposes to determine methods to enhance the security and operation of SBD systems. With the aim, this paper investigated the existing literature on SBDs, self-check-in, airport security, air terrorism, risk management, aviation accidents, and information security. In order to compile real-time information about the SBD operations, twelve airports in North America, Europe, and Asia were analyzed based on existing studies on international SBD trends.

This paper describes the effect of advice information for arriving aircraft landing order on the air traffic controller's work efficiency. The air traffic control simulator used in the experiment was modeled on the basis of the aircraft parameters from BADA, gamma-command model and the 4-dimensional trajectory using the Bezier curve. The simulation results show that advice information was helpful for the performance of the work for users who did not have the air traffic control training. On the other hand, in case of users who have experience in air traffic control training, the work efficiency was lowered when the advisory information that does not reflect the user's intention is provided. Therefore, it can be seen that the effect of improving the work efficiency through advice information can be limited depending on the skill level of the air traffic controllers and the complexity of the air traffic situation.

The world air transport industry has grown steadily with quantitative expansion. The volume of air transport in the world is skyrocketing with the open-sky trend. Air passengers from or to South Korea has shown 5% of annual growth for the last couple of decades which caused South Korea now ranking in 18th in the World for air transport market size. Quantitative expansion of Air transport affects in policy making of air transport operators, such as airports, airlines or authorities, directly and indirectly. Especially, Aviation Safety field should be supported by policy regime with the growth of air transport volume, assured resources for continuous monitoring is standing out as a vital factor. This study is to estimate social costs caused by aviation accidents and investment costs for aviation safety by airports, airlines and authorities as operators. Estimated investment costs for aviation safety verified by comparing and analysing them. Precedent studies were reviewed to refer research methodology to calculate aviation accident costs and safety costs of operators. Safety costs of operators was calculated with literature researches and interview surveys among professionals of each operators in rational range.

The study of the safety perceptions between two groups, trained and untrained student pilots were compared as pre-studies of that how the safety perceptions of the flight instructors affect that of the student pilots. As a results, the factors of the communication and the safety procedures shows higher values on the one-year trained group than the other because the trained students get used to the safety procedures which are necessary to the practical training. In reliability for the flight instructor, the factors of two groups show the high tendency without regard to groups. Despite of the lack of the specific research, the result implies that the student pilots are influenced by the safety perceptions of the flight instructors. In addition, the factors of the accident report were investigated as that the trained group has lower mean, however the factors of the receiving penalties of the trained group were higher than the other. These results imply that the trained group feels concern for the penalties and the punishments by reporting the accidents in spite of amounts of the training.

It is well known some Foreign aircraft used to fly INCHEON FIR(Flight Information Region), especially the island of IEODO without a flight plan, even though foreign aircraft is subject to submitting a flight plan to Flight Information Center(FIC) before its flight. IEODO is a sunken rock 4.6m beneath the sea level, 149km away from Marado. Facing the Yangtze river's sea entrance horizontally and military zones of Korea and China vertically, IEODO is a very important place for national security of North East Asia because it is located at the boundary between China East Sea and Yellow Sea of South Korea. Moreover, JDZ(the 7th mine lot) is just 77NM from IEODO, which possesses natural gas eight times bigger than the gulf region and oil 4.5 times bigger than that of the U.S. In addition, INCHEON FIR, managed by MLTM(Air Traffic Control Center) and Japanese Self-Defense Force's JADIZ(Japanese Air Defense Identification Zone) are overlapping on IEODO whose air space is very complex. This paper focuses on air space, FIR, ADIZ(Air Defense Identification Zone) and related airspace system and suggests strategic implications of how to prevent foreign aircraft from invading INCHEON FIR without permission and of how to utilize the airspace efficiently.
