Aircraft Arrival Time Prediction via Modeling Vectored Area Navigation Arrivals
Hong, Sungkwon ; Lee, Keumjin ;
Journal of the Korean Society for Aviation and Aeronautics, volume 22, issue 2, 2014, Pages 1~8
DOI : 10.12985/ksaa.2014.22.2.001
This paper introduces a new framework of predicting the arrival time of an aircraft by incorporating the probabilistic information of what type of trajectory pattern will be applied by human air traffic controllers. The proposed method is based on identifying the major patterns of vectored trajectories and finding the statistical relationship of those patterns with various traffic complexity factors. The proposed method is applied to the traffic scenarios in real operations to demonstrate its performances.

'Visual segment surface' means a surface that extends from the missed approach point of non precision approaches (or the decision altitude location for approaches with vertical guidance and precision approaches) to the threshold to facilitate the identification of and protection from obstacles in this visual segment of the approach. Validation is the necessary final quality assurance step in the procedure design process, prior to publication. The purpose of validation is the verification of all obstacle and navigation data, and assessment of flyability of the procedure. This paper shows how to apply the protection for the visual segment of the approach procedure, and the results of the validation for visual segment surface conducted at an airport.

After the GBAS ground system installing at the airport, a GBAS ground and flight testing must be conducted to verify functionality and performance of the system. Since Korea has no experience of the GBAS ground system installation, GBAS test and evaluation methods have never been studied so far. Therefore this paper analyzes the test items and methods for the GBAS ground and flight testing based on ICAO documents, FAA flight inspection manual and testing reports of other countries. As a result of the analysis, this paper proposes the GBAS ground and flight testing items in korea, also describes the flight procedures for the GBAS flight testing.

There are several methods to improve the flight efficiency of HALE(High Altitude Long Endurance) UAV(Unmaned Aerial Vehicle). Airframe structural point of view, weight reduction of the airframe structure is the most important method to improve the flight efficiency. In order to reduce the weight of airframe structures, new concepts which are different from traditional airframe structure design such as the mylar wing skin should be introduced. The spar is the most important component in a mylar skin wing structure, so the spar weight reduction is the key point for reduction of the wing structural weight. In this study, design trade-off study for the front spar of the HALE UAV wing is conducted in order to reduce the weight. Design and analysis procedure of high aspect ratio wing spar are introduced. Several front spar structures are designed and trade-off study regarding the weight and strength for the each spar are performed. Spar design configurations are verified by the static strength test. Finally, optimal front spar design is decided and applied to the HALE UAV wing design.
A Study on the Application of Operational Experience in the Stage of Aircraft System Design and Safety Assessment
Koo, Min-Sung ;
Journal of the Korean Society for Aviation and Aeronautics, volume 22, issue 2, 2014, Pages 34~39

Airworthiness authorities specify the technical standards of airworthiness that propose minimum requirement of the commercial transport category and apply the rules in the certification process to ensure the safety of the aircraft. The Federal Aviation Administration and other national airworthiness authorities define the fatal accident risk levels for the safety assessment of the aircraft system and establish standard procedures to apply both qualitative and quantitative analysis techniques. However, an accident or incident may occur by the combination of various factors, although the aircraft is designed in accordance with the strict standards and approval by the Airworthiness Authorities. There are some key factors, such as human error, unpredictable complex system failures, degradation of the components reliability, improper maintenance task and intervals. Risk can be reduced by reflecting aircraft operational experience with similar types of aircraft in the process of aircraft development and safety assessment. Result of the root cause analysis for the Airbus A300-600 incident in which the aircraft engine reverser was deployed in the air have been introduced to reflect the design of system and related components. Also, this paper suggests to create a big-database in order to provide a feed-back to the FAR Part 25 transport category design and safety assessment of the operational experience.

Shin, Gwon-Sang ; Yuh, Song-Hee ; Lee, Hyung-Bok ;
Journal of the Korean Society for Aviation and Aeronautics, volume 22, issue 2, 2014, Pages 53~59
DOI : 10.12985/ksaa.2014.22.2.053
Simultaneous parallel approaches in all weather conditions should be applied to manage efficiently increasing volume of air traffic flow and solve the problem of delayed arrivals. But All of the airports which have closely-spaced parallel-runways in Korea don't meet the interval-standards for IFR parallel approaches. In that regard, more accurate and safer System should be applied for the Korean airports. GNSS was adopted as an international standard of the next-generation navigation system and many studies and master plans have been activated by stages in Korea. In this paper, the current state of the domestic airports will be analyzed focusing on the interval of parallel runways and future specification of both flight operation system and air-side management will be recommended.

Cho, Sung Hwan ; Kim, Ki Woong ; Park, Sung Sik ;
Journal of the Korean Society for Aviation and Aeronautics, volume 22, issue 2, 2014, Pages 60~70
DOI : 10.12985/ksaa.2014.22.2.060
This paper has tried to research the perception of pilots in a commercial airliners or full service carriers focusing on the airliner's safety management system (SMS). ICAO requires the airliners to set up the basic standards of SMS since the SMS is believed to be the core of the aviation risk management. According to the previous study, it was proved safety climate of an airline affects the safety behavior of cockpit crews. Safety climate is different from safety culture and the safety climate has an advantage to be measured more quantitatively than the culture. That is, the safety climate could be represented as SMS. As the results of the empirical study based on Chen & Chen(2014)'s SMS practice sacle, it had been assumed at the beginning the major factors such as Clarification of SMS, Safety Training for Crews and Sharing of SMS Information have positive effects on the motivation for safety behaviors. The motivation is directly correlated to crews' safety behaviors. However, the result showed the clarification of SMS has not a significant effect on their safety behaviors. The main reason is cockpit crews, through the survey, perceived airline seemed to have no definite standards of SMS and the senior management to have less interest in aviation safety.

Incheon international airport has tried to upgrade its image by hosting lots of international events and inviting celebrities as a honorary ambassador of airport. It is uncomparable to other airports all over the globe for incheon airport to utilize an honorary ambassador to promote airport. The purpose of this paper is to try to find out the PR effect of employing honorary embassador at Incheon airport, which has a positive impact on enhancing the image of Incheon airport. In other words, it should be considered the PR effect of honorary embassador has contributed to upgrading airport image resulting in the commitment of passengers. According to empirical research result, it is proven the attractiveness and trust of honorary embassador has not significantly positive impact on the airport's image. However it is also proven the PR activities of airport authority has a significant impact on the airport's image. Passengers believed the honorary ambassador has a high level of attractiveness and trust but they don't agree causal relationship among attractiveness, trust and airport image. That is, they are not interested in who is the honorary ambassador of airport but in the contents of airport's news article itself. The administrative implication is mentioned in the paper that airport authority should mainly focus on the contents of PR not the figure of the honorary ambassador.
