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.

The flight deck crew are under the operational time pressure in the cockpit. The crew tend to make errors when they face the threats of operational time pressure because they are in a rush. The flight deck crew can reduce threats and errors which existing within the airlines by using threat and error management when the crew know these threats and errors. The airlines can implement meaningful safety management system by analyzing into the useful information for to identify the hazard and manage the risk to reduce these threats and errors since aircrafts accidents can be fatal.With the threats and errors that were found regard to operational time pressures, company may implements safety change process to improve the safety systematically and the crew can manage the threats and errors more effectively.

점증하는 항공교통량의 원활한 수용과 안전한 항공기술 저변확대를 위하여 ICAO는 성능기반의 항공교통관리(ATM) 체계와 시스템을 Upgrade할 구체적 이행계획인 ASBU를 개정하고 체약국들의 수용을 촉구하고 있고, 우리나라는 ICAO의 5연임 이사국으로서 ASBU의 주요 Module에 대응하는 모든 Working Paper에 대하여 적극 수용한다는 입장이다. 본 논문은 ASBU의 PIA 4에 해당하는 CDO 및 관련 Module인 TBO의 개념을 살펴보고, 선도적으로 운용되고 있는 사례를 분석해 봄으로써 미래에 대응하는 방안을 찾고자 하였다. CDO는 새로운 장비와 시스템을 갖추지 않더라도 절차의 보완으로 개선할 수 있는 부문에 속하므로 우리나라의 운영 현황을 리뷰하고 그 영향에 대하여 정리해 보았다. 다만, 항공기 고도 강하 단계에서의 개선효과가 상승 또는 순항 단계에 비하여 효율성이 상대적으로 미미한 편이고, ATM 구분 상 기상 등의 외부 변수에 취약하여 효율성 연구에 접근하기 어려운 면이 있으나, 고밀도 공항의 특화된 CDO 기법 개발을 통하여 연료절감 및 탄소배출량 저감, 소음감소의 성과를 이룬 선진 사례를 들어 국내에 적용할 수 있는 방안에 대하여 장기적으로 연구하고자 한다.

항공교통수요의 증가와 그에 따른 항공분야 발전에 따라 현재 사용하고 있는 항행안전시설들에 대하여 기술적 보완 및 업그레이드의 필요성이 대두되었다. 국제민간항공기구(ICAO)에서는 항공교통량의 증가를 수용하고, 항공 운항의 안정성과 효율성을 높이기 위해서 차세대 항행시스템(CNS/ATM)으로의 전환을 권고하였고, 각 국은 기존 항행시설의 성능과 한계를 극복하고 증가하는 항공교통량을 원활히 수용하기 위하여 차세대 항공교통관리 전략을 추진해 오고 있다. 이러한 차세대 항행시스템(CNS/ATM)의 효과적인 활용을 위해 자동화 시스템이 도입되었고 관련된 인적요소가 위성항행시스템 발전의 핵심 열쇠라고 ICAO에서 언급하였다. 본 논문에서는 차세대 CNS/ATM의 자동화에 따른 인적요소에 대하여 연구해 보았다.

As a method to come up with the low competence of responsible officers, an integrated system providing watch officers with information on navigation obtained on board and on land as well is needed to secure the safety of navigation. Therefore as an approach to improve the function for safe navigation, this paper is to develop, efficiently and economically, an integrated system of ship's information.

The worldwide improvement of the safety, efficiency and rationality in the field of aircraft operation environment and certificate management of aviation personnel has been proceeded cheerfully as a part of each country's globalization movement. Considering the importance of aviation transportation industry supporting nation's international trading has the competition among the airlines regarded possibly as that among the countries. In order to make Korean Government and Airlines more competitive in this race, the standardization and generalization of aviation regulations are required. On this study, some amendments are recommended to improve regulations and systems for pilot's certification management and operation environment by comparison analysis of regulations of ICAO, FAA and Korean aviation law.

As the domestic aviation industry develops, demand for pilots is increasing. As a result, the demand for flight training using flight simulation training devices that implement the same or similar interior of aircraft is also increasing. Despite this increase in demand, domestic laws, regulations and management systems related to flight simulation training devices have remained unchanged since 2009. As a result, the criteria for designation of new or developed flight simulation training devices are ambiguous. In addition, proper improvement of the current system should be prioritized for designation of new devices such as UAM and VR, along with developing flight simulation training devices. It is intended to present measures to improve the domestic flight simulation training system by investigating and analyzing advanced cases overseas.

In order to predict the future needs of the aircraft repair parts, each military group develops and applies various techniques to their characteristics. However, the aircraft and the equipped weapon systems are becoming increasingly advanced, and there is a problem in improving the hit rate by applying the existing demand prediction technique due to the change of the aircraft condition according to the long term operation of the aircraft. In this study, we propose a new prediction model based on the conventional time-series analysis technique to improve the prediction accuracy of aircraft repair parts by using machine learning model. And we show the most effective predictive method by demonstrating the change of hit rate based on actual data.
