Military UAV(Unmanned Aerial Vehicle) operated as a RC(Remotely Control) model level within the limit of the military special use airspace until now. However, the high and medium altitude of URA(Unmanned Reconnaissance Aircraft) which the ROKAF have been trying to import recently is at the UAV level and needs the criteria for the classified airspace flights. The required flight criteria includes operator location, mission operation limit, equipment, etc., which are the principle and standard applied based on the airspace use for UAV. Also, the general flight rules, visual flight rules, instrument flight rules are required in order to have to be applied to the actual flight. Besides, an appliance regulation needs to be arranged regarding two-way communication, ATC and communication issue, airspace and area in-flight between UAS( Unmanned Aircraft System) users. An operation of the UAV in the air significantly requires the guarantee of the aircraft`s capacity, and also the standardized flight criteria. A safe and smooth use is ensured only if this criteria is applied and understood by the entire airspace users. For the purpose, a standardized military UAV flight operations criteria that is to be applied for each airspace by UAV is to be prepared through analysis of the present state, a legend UAV system, and a special character analysis.

Incheon international airport has been successful, that is, the winner of Airport Service Quality (ASQ) evaluation performed by ACI(Airport Council International) for nine consecutive years. It goes without saying that such an outstanding performance was made not only by airport authority itself but by the collaboration among subcontractors at Incheon international airport. Since Incheon airport is showing more than 80% of outsourcing rate, it is important to mention and study the roles and functions of subcontractors who has made a major contribution to ASQ performance. According to empirical research in this paper, it was found out service attitude, communication skill and interdependence between airport authority and subcontractors were important factors affecting the ASQ score. It is also analyzed that those independent factors have an impact on ASQ performance through the intermediate factor of trust. As a result, service attitude and interdependence between airport authority and subcontractors have statistically a significant effect to the relational satisfaction and ASQ performance. It could be concluded that trust is significant factor determining the causal relationship among service attitude, communication skill, relational satisfaction and ASQ score.

A customer loyalty program (i.e., FFP) has become more important to keep loyal customers especially for legacy airlines. Therefore, the researchers intended to examine the elements of an airline loyalty program and how these elements influenced the effects of the loyalty program. To set up the research framework, the commitment-trust model (i.e., KMV model) in the loyalty program was used in this study. Shared values, benefits, serviceabilities, and affiliated companies were considered as independent variables (i.e., elements of FFP). Trust and commitment added as mediating variables and customers` loyalty were examined as a dependent variable. A survey has been conducted. All independent variables had positive relationships with trust and commitment and trust influenced commitment. Lastly, the mediating variables had positive effects on customers` loyalty.

Due to the recent aircraft accidents both in Ethiopian airline and Malaysian airline, almost all the media are focusing the importance of the airline safety. Especially, media`s eyes and ears are interested in the reasons why Malaysia airline`s missing presumed as by either terrorist attack or pilot`s mistake. Safety Behaviors of pilot are viewed as the most important human factor issues among researchers. This is because, if it were the case of a commercial airline, pilot`s safety behavior would be directly related to the lives of couple of hundreds passengers. This paper considers the antecedents of this safety behaviors as pilot`s leadership, pilot`s leadership and self-efficacy. This paper has tried to find out which human factors of a pilot would have significant impact on their safety behaviors. According to the empirical research result from SEM (Structural Equation Model), it was found out both the leadership and self-efficacy of a pilot had direct impact on their safety behaviors through safety motivation. Thus it could be concluded that flight crew must follow the instruction of a pilot who had the authority of the flight operation. The managerial implication are discussed in the conclusion part of this paper. As an implication, this paper concluded that it would be necessary to do further research on pilot`s leadership and self-efficacy.

FOD(Foreign Object Debris) has the potential threat to damage aircraft during critical phases of take-off and landing roll with some objects including metal on the runway. FOD can be found anywhere on an airport`s air operation areas such as runway, taxiway and apron. It can lead to catastrophic loss of life and airframe, and increased maintenance and operating costs. In this paper, we defined FOD and surveyed its riskiness and necessity of automatic FOD detection system. We compared the requirements of the environment in Korea to the FAA advisory circular. Also we analyzed operation methods of FOD detection systems already installed at some airports. Based on the surveys mentioned above, we propose hybrid type of FOD detection system considering the environment in Korea which uses millimeter wave radar, optical camera and thermal imaging camera to detect FOD efficiently. In management approach, fixed type of the system should be installed for real-time monitoring, and mobile type of the system can be used additionally.

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.
