MISSING Malaysia Airlines flight MH370 has not been discovered and unknown whether it crashed on the ground or under the sea. There are a couple of emergency equipment in the airplane not only outside of airplane but inside airplane such as ELT(Emergency Locator Transmitter). Since the ELT developed, it is required to be installed in the airplane for regulation requirement. However, despite of its important function, it is not working properly or shows wide search range for rescue during the crash or ditching on the water. I would like to propose how to over come the up-to-dated position data just before the event. Connecting with ADIRS or GPS which is installed internal airplane system will help to reduce the rescue time for survival passenger.

항공 운송량의 증가로 운항 중 예상치 못한 난류(Turbulence)에 직면하는 경우도 증가하고 있다. 이로 인한, 손님/승무원의 부상, 화물 손상, 항공기 효율성 하락 등으로 많은 Cost가 발생하고 있으며, 항공 안전에도 치명적인 위협이 되고 있다. 하지만, 이에 대한 정보는 운항 중인 항공기의 조종사기상보고(Pilot Weather Reports, PIREP)에 의존하여 발생 지역을 예측하고 있으나, 보고시간 지체에 따른 부정확한 위치, 주관적인 강도 예측으로 실제 유사 지역을 운항하는 항공기에 도움을 주는데 한계가 있다. 금번 논문에서 TAPS(Turbulence Auto PIREP System)의 원리와 실제 운영하는 항공사의 활용 방안을 고찰하여, 정보의 자동 송/수신을 통한 실시간 난류 정보 제공으로 위험 요인을 사전 인지하여 제거할 수 있는 방안을 살펴보고자 한다.

The air transportation industry in Korea has grown very fast in aspect of the transportation scale as much as entering within the tenth in the world. However, as compared with the air transportation industry, the civil aviation pilots training has been performed at very low level in quantity and quality because of the high cost of pilots training, nation security, limited airspace use and falling behind of the science technology in relation to the aviation industry. In result, the number of airline pilots became lower than actual demands of both airlines, KAL and ASIANA. This produced many foreign captains employed, airline pilots overloaded and finally affected flight safety. In this paper, it was studied the actual reality and problems of civil aviation pilots training and presented the encouraging policies for civil aviation pilots training in Korea.

This study deals with the overall meta-cognitive aspects of ATC-Pilot miscommunications pertinent to cognitive human errors based on the previous literature research which it has been focused on the issue of the global aviation English use in regard with aircraft accident and incident. Especially, it addresses the concern over the ICAO aviation English language proficiency evaluation program which will be implemented globally in March, 2008. In addition, It presents the analysis related to the on-going English language proficiency level four test conducted for Korean civil airlines pilots and air traffic controllers.

Since it's introduction in the late 19 century, the railway has taken an important role as people's feet and has conducted a stable management due to it's exclusive position for a long time. However, the competitions with other transportation devices such as cars and airlines are making it's previous position more or less weaker. In 1998, celebrating 100th anniversary, Korea Railway established the Customer Satisfaction Service Charter for the purpose of overcoming this competitive weakness, and as well to enhance it's service quality. The main purpose of this article is to depict and review the effectiveness of Customer Satisfaction Service Charter that has been adapted for a decade, and to suggest some effective supporting system that can make the charter to function more efficiently, and that would lead to the better realization of customer satisfaction service.

We conduct the future studies suggested by Park and Seo [3]. They considered a seat inventory control problem in which flights depart sequentially during a similar time-interval and passengers purchase available seats depending on individual customer choice behavior. Customer choice behavior can lead to one among a horizontal shift, a diversion-up, and a booking loss when a desired fare class is unavailable. We investigate how seat availability calculation method, booking limit control mechanism, seat inventory capacity, number of booking class, type of seat demand influence on revenues in an airline industry through thorough computer simulation experiments.

A reduction in search costs is generally believed to make markets more competitive. However, the effect may be mitigated or amplified if consumers must pay costs for switching products. This paper investigates how search costs affect prices in the presence of switching costs using U.S. domestic airfare data for 2000-2010. The airline industry experienced a dramatic decrease in search costs with increasing Internet use in the 2000s. At the same time, the industry is known for its frequent flyer programs (FFPs), which increase switching costs for consumers. We use the average network size of airlines in a market as a proxy for switching costs related to FFPs and Internet usage as a proxy for (the inverse of) search costs. The results show that increasing Internet usage lowers airfares but that the effect is smaller for markets with a larger average network size.

This study examines hypotheses that four personality traits(extroversion, emotional stability, openness to experience, and agreeableness) have effect on emotional exhaustion among flight attendants. Questionnaires were collected from 344 flight attendants working for two airlines in Korea. From the hierarchical regression analysis, this research could find out some results such as follows. First, extroversion, emotional stability, and agreeableness, with the exception of openness to experience, decrease the level of emotional exhaustion. Second, according to the results of these analyses organizations should consider employee's personality fitting to job in selection process.

The strengthened aviation security measurements caused by increased terror threat all around the world have air passengers annoyed by uneasy treatment and some delayed process. The service level of air travel and competitiveness of airlines industry has been weakened also. The aviation security process is mainly conducted at an airport. The threat level of airport is not usually same airport to airport, and the quality of aviation security activity is neither same. However, ICAO requires every international airport to conduct similar process to ensure aviation security without considering situational difference of each airport. The paper has objectives to develop reasonable security measurements based on risk management concept. It studied the ways of achieving target level of security of an airport, considering the threat situation of the airport and its ability to conduct security procedures.

Pilot has been fighting to get over fatigue during flight and thought it as a hinderance for safe flight. The fatigue related problem has been the biggest obstacle for aviation safety so far. Even though pilots and airlines try their best to overcome fatigue during flight, they couldn't overcome this problem. So the airliners let the pilot sleep during flight if pilots are too tired with the report. It is controlled rest used and managed by several European airliners. So this study tries to get Korean airline pilots' fatigue information and figure out the cause and reduce it.
