Kim, Do-Hyun ; Hong, Seung-Beom ;
Journal of the Korean Society for Aviation and Aeronautics, volume 23, issue 2, 2015, Pages 1~6
DOI : 10.12985/ksaa.2015.23.2.001
The RSA is intended to prevent the following five types of events from becoming an accident: landing overruns, landing undershoots, landing veer-offs, takeoff overruns and takeoff veer-offs. The improved models are based on evidence from worldwide accidents and incidents that occurred during the past 27 years. The analysis utilizes historical data from the specific airport and allows the user to take into consideration specific operational conditions to which movements are subject, as well as the actual or planned RSA conditions in terms of dimensions, configuration, type of terrain, and boundaries defined by existing obstacles. This paper shows how to apply the improved models for Risk Assessment of Runway Safety Areas (Airport cooperative research program(ACRP) Report 50) into an airport and the outcome differences between the old models based on ACRP report 3-Analysis of aircraft overrun and undershoots for runway safety areas and the new models from ACRP report 50 in the specific airport.

Cho, Hwan-Kee ; Kim, Jong-Bum ; Song, Byung-Heum ;
Journal of the Korean Society for Aviation and Aeronautics, volume 23, issue 2, 2015, Pages 7~14
DOI : 10.12985/ksaa.2015.23.2.007
This paper deals with an optimal determination process for the built-in location of localizer under restrictive siting area conditions of a domestic P-airport. Aerodynamic forces and moments acting on the localizer structure can be used a reference to find the safe distance from jet blast and the position at which the reasonable structural loading is applied. Wind tunnel experiment is conducted to measure aerodynamic loadings. The finite element analysis for structural deformation is employed to get the information of structural failure. A new localizer's position is determined by considering aerodynamic loading, structural strength and thermal loading due to jet blast. Deflector effect was also investigated in this study. In conclusion, the location of localizer can be placed at shorter than the current position and greatly decreased if the deflector is applied at the front of localizer.

Airport is not only a public facility but a place where multiple cultural and ethnic groups are visiting. It has been reported though several researches that the level of emotional labor is more heavier than any other job. The more complex our society become, the more frequently emotional labor has been focused. Emotional labor became recently the issue of integrated studies above. Considering the level of emotional labor of airport employees, this paper believes their emotional labor has not been focused compared to such as tourism and service industry. This paper tried to research empirically the impact of internal marketing on airport employees' customer-oriented attitude based on their emotional labor using SEM (Structural Equation Modeling). According to the SEM results, it was proven that 'Autonomy of Airport Employee', a latent variable of internal marketing has a significant negative effect on employees' outside emotion. The outside emotion has also a significant effect on their customer-oriented attitude. It could be concluded the effort to increase decision making authority of employees should be implemented to provide them with deeper customer oriented insight.

This study deals with transfer passengers in hub airports. The research objective is to derive measures for transfer passenger quantity enhancement at Incheon International Airport by applying Analytic Hierarchy Process. In pursuing the above objective, this study conducted a survey to evaluate various selection criteria for choosing transfer airports and ranked attributes in weight order with Analytic Hierarchy Process. Furthermore, based on the trend analysis of Incheon International Airport's transfer passenger movement, this paper analysed main transit routes of Incheon International Airports against competitor airports among the region. The main result found from the study is flight frequency, ticket price and connecting hour were the most important 3 factors when people choose transit airports. Therefore, it is recommended government, airport authority and airlines to cooperate closely to meet the transfer passengers' needs on frequency, price and transit hour of flights.
In-Flight and Numerical Drag Prediction of a Small Electric Aerial Vehicle
Jin, Won-Jin ; Lee, Yung-Gyo ;
Journal of the Korean Society for Aviation and Aeronautics, volume 23, issue 2, 2015, Pages 51~56
DOI : 10.12985/ksaa.2015.23.2.051
This paper presents the procedure of drag prediction for EAV-1, based on a numerical analysis correlated to an in-flight test. EAV-1, developed by Korea Aerospace Research Institute, is a small-sized UAV to test a hydrogen-fuel cell power system. The long-endurance test flight of 4.5 hours provides numerous in-flight data. The thrust and drag of EAV-1 during the flight test are estimated based on the wind-tunnel test results for EAV-1's propeller performance. In addition, the CFD analysis using a commercial Navier-Stokes code is carried out for the full-scale EAV-1. The computational result suggests that the initial CFD analysis substantially under-predicts the in-flight drag in that the discrepancy is up to 27.6%. Therefore, additional investigation for more accurate drag prediction is performed; the effect of propeller slipstream is included in the CFD analysis through "fan disk" modelling. Also, the additional drag from airplane trim and load factor that actually exists during the flight test in a circular path is considered. These supplemental analyses for drag prediction turn out to be effective since the drag discrepancy reduces to 2.3%.

As the issuance of type certificate and production certificate for KC-100 Naraon, Korea is ranked as the State of Design and the State of Manufacture for civil aircraft specified in the Convention on International Civil Aviation. It means that another responsibilities are imposed and new frameworks are required for the airworthiness management including the continuing airworthiness. So far the minimum airworthiness management system was sufficient as the State of Registry for the aircraft operations and safety management. However, we need to establish and maintain the airworthiness management system for the effective certification and oversight of our air operators and approval holders. This paper introduces the new obligations under the Convention on International Civil Aviation, reviews the current aviation regulations and procedures and presents the strategy for the establishment of the regulatory system to ensure the airworthiness of aircraft.
Design of Envelope Protection Algorithm for Helicopters
Ko, Joon Soo ; Park, Sungsu ; Kim, Kyungmok ;
Journal of the Korean Society for Aviation and Aeronautics, volume 23, issue 2, 2015, Pages 63~68
DOI : 10.12985/ksaa.2015.23.2.063
This paper presents the algorithm for envelope protection of helicopters. The algorithm consists of two feedback control loops: inner loop and outer loop. As an inner loop control, model following control is designed to meet the ADS-33 handling qualities specification by minimizing the tracking errors between the responses of the actual model and those of the command filter. In order to implement envelope protection, saturation limiter is imposed to command channels in command filter, whose limits are computed corresponding to the envelope limit. Fast model predictive control is designed as an outer loop control to deal with saturation constraints generated by the inner loop envelope protection and also imposed by outer loop envelope protection variables. Simulation results show that the proposed algorithm yields good envelope protection performance.

We propose a rigorous and practical methodology to evaluate the performance of symbolic manipulation program such as Mathematica, Maple, and Maxima. First, we demonstrate an inverse method to construct the benchmark problems of an initial value problems. The benchmark problems associated with the discrete version of the Chebyshev polynomials provide a rigorous and objective measure to evaluate the performance of symbolic manipulation programs. We compare three symbolic manipulation programs, which are Mathematica, Maple and Maxima, using this methodology. The computation time, the used memory and the perturbation terms are chosen for comparison parameters.

Advanced countries in the aviation industry, especially the United States and European Union, develop and commercialize their own SBD system integrated with IT convergence technology, dominating the international market. Nevertheless, most of SBD technologies in domestic airports rely on other countries. It is imperative that internal airport operators introduce the Self Bag Drop system and produce, apply, and manage the most optimized SBD system for airports and airlines. Upon analyzing the tendency and operation of the SBD system utilized in leading international airports, this is conducted to address the possibility of the future implementation in domestic airports.

The volume of transfer passengers now faces a crisis because the number of Chinese and Japanese passengers, the majority of transfer through Korea, is decreasing. This paper is analyzing the their air travel behaviors as well as characteristics of their transfer behaviors at airport. According to the research, it is suggested that transfer passengers perceive the importance of duty-free stores but their satisfaction of using duty-free stores during their transfer at Icheon airport was proven to be low. Considering the characteristics of transfer service quality at Incheon airport, waiting time of transfer is important but not satisfactory for them. Moreover, information of free transfer tour to city downtown and paid-in transfer tour for medical tourism is not known very well among North East Asian passengers. Thus, it is necessary to do detailed research of North East Asian transfer passengers, who have transferred through Incheon airport more than twice a year, to find out their exact needs of transfer tour in Korea.
