RVSM은 특정 공역내에서 비행고도 FL290~FL410를 운항하는 항공기간의 수직분리기준을 기존의 2,000ft에서 1,000ft로 축소, 추가적인 운항고도를 제공함으로서 기존의 공역수용능력을 증가시키기 위한 목적으로 실시된다. 해당 공역에 RVSM을 도입하기 위해서는 RVSM을 적용할 경우 예상되는 항공기간 충돌가능성을 정량적으로 분석하는 것이 필수적이며 RVSM 공역을 운항하려는 항공기는 고도유지성능이 일정 수준을 만족함을 입증하여야 한다. 본 연구에서는 RVSM의 개념을 소개하고 RVSM 공역수립 및 유지를 위해 요구되는 사항을 분석하였다.

Recently increase in the number of aircraft caused the air traffic congestion and flight delays. If timely action to reform the air traffic system is not taken, these may result in added economic impact. As a result, the air traffic management should be changed in an innovative manner to modernize the existing air traffic control environment. This paper reviews the trends of airspace reforms such as integration of terminal control areas and flexible use of airspace introduced by foreign countries and compares their merits and demerits in order to provide a judgement to adopt the concept in domestic airspace in the future.

Demand for air transportation in Korea keeps increasing, and the number of airport operations also grows as a result. The major two airports in Korea, Incheon International Airport and Gimpo International Airport, share the metropolitan airspace, which is crowd with air traffic. As air traffic increases in the metropolitan airspace, the demand for the airport operations would outnumber the capacities of these airports. However, there is a room to efficiently manage the shortage of the airport capacity due to the different distributions of operations in these airports. This study presents a dynamic slot allocation that allows exchanging slots according to the traffic demand. The dynamic allocation mitigates the airports' capacity problem but the airspace capacity itself should be increased in order to tackle the problem fundamentally.

Recently avionics equipment and its integration are most important part for implementing high performance aircraft system. This trends are emphasized in the military or special purpose aircraft development program. Flight Test Bed Aircraft (hereafter FTB A/C) - by modified commercial aircraft - was key solution to verify function and performance of avionics system for complex aircraft development program for a while, but there are no experience to use it in domestic airspace of ROK. This paper would like to address what act and regulation is necessary to perform flight operation of FTB A/C with keeping a airworthiness and airspace control policy. and then willing to propose what do we do for improving aviation industry.

영공을 침범한 민간항공기에 대한 무력행사의 한계에 대해서는 국제법상 정립되어 있지 아니하다. 따라서 본 논문에서는 민간항공기의 영공침범에 관련된 국제법과 국제관행을 살펴보고, 특히 정치적 테러 수단으로 피랍된 민간항공기에 대한 무력행사의 적법성을 고찰하고자 한다. 본 논문의 연구범위는 평시에 영공을 침범한 민간항공기에 대한 요격 문제에 한정하고 있으며, 국가항공기의 영공침범에 관한 문제나, 요격으로 인한 민형사상의 책임에 관한 문제는 배제하고 있다. 본 논문에서는 영공을 침범한 민간항공기에 관련된 현행 국제법규와 각국의 무력행사 사례들을 분석하므로써, 국제법과 국제관행상 용인되고 있는 무력행사의 요건들을 정립하고, 그것들을 정치적 테러수단으로 피랍된 민간항공기의 특별 사례에 적용하고 있다. 결론적으로, 본 논문에서는 영공을 침범한 민간항공기에 대한 무력행사의 요건으로서 필요성, 최후수단성, 비례성이라는 기본원칙을 제시하고 있으며, 정치적 테러수단으로 피랍된 민간항공기에 대한 무력행사의 가능성에 대해서는 당해 국가안전의 필요성이라는 요인 때문에 다른 어떠한 형태의 영공침범 민간항공기에 대한 것 보다도 높을 수 밖에 없음을 마지막으로 제시하고 있다.

Obstacle defines all fixed and mobile objects, or parts thereof, that are located on an area intended for the surface movement of aircraft or extend above a defined surface intended to protect aircraft in flight or stand outside those defined surfaces and that have been assessed as being a hazard to air navigation. The airspace around airports are maintained free from obstacles so as to permit the intended aeroplane operations at the airports to be conducted safely and to prevent the airports from becoming unusable by the growth of obstacles around the airports. This is achieved by establishing a series of obstacle limitation surfaces or airspace imaginary surfaces that define the limits to which objects may project into the airspace. This is a case study that shows an application of obstacle limitation criteria, which must be maintained free from an critical obstacle, for specific conditions of two airports. For the purpose of the application, aeronautical studies/flight safety influence assessments were used to identify possible solutions and select a solution that is acceptable without degrading aviation safety.

Drone remote identification (ID) capability is essential to ensure public safety, help law enforcement, and secure the safety and efficiency of the national airspace. Remote ID technology can be used to differentiate compliant drones from illegal drones that pose a potential security risk by providing airspace awareness to the civil aviation agency and law enforcement entities. In addition, the increased safety and efficiency obtained by mandating remote ID will make it possible to operate drones over populated areas and beyond visual lines of sight. In addition, remote ID will allow drones to be safely integrated into unmanned traffic management systems and the national airspace. Remote ID devices can be categorized by type, i.e., broadcast remote ID or network remote ID. The broadcast remote ID, which has high technical maturity and will be applied in the near future, is primarily considered to ensure the security of drones. The network remote ID, which is being developed and tested and will be applied in the distant future, can be used additionally to ensure the safety and the efficiency of the national airspace. In this paper, we analyze the trends on regulation and standardization activities for drone remote ID primarily in the United State and Europe.

ICAO recommended that airspace monitoring and periodic safety assessments in each Contracting State ensure the stability of the airspace, since reducing the aircraft lateral and vertical separation intervals would rather increase the risk of collision. The target level of safety of the AKARA-FUKUE Corridor at the southern end of Jeju was 247×10^-9. In simple comparison, this means that the risk of an aircraft collision in this area (international safety standards, 5.0×10^-9) is about 50 times higher. The scope of this study is to organize the concept of terms, analyze the air traffic volume, the current status of navigational safety facility usage fees, and investigations of an aircraft collision risk in Jeju southern air corridor. Analyzing government policies and overseas evaluations, revising some of the existing contents, presenting some of the additional contents of new routes, and changing the instrument procedure for Korean-Chinese routes, change of arrive/departure route between Incheon Airport and Shanghai Airport, reduce the risk of aircraft collisions. We hope to restore airspace sovereignty, contribute to policies for the government to take the lead in solving this problem, and expect stability and operational efficiency in air traffic.

Being a cost-efficient solution for alleviating the traffic congestion in airspace, Air Traffic Flow Management (ATFM) has drawn more attentions from not only air traffic controllers but also researchers in the field of Air Traffic Management (ATM). Among other ATFM initiatives, it is believed that Ground Delay Program (GDP) could be effectively applied to reduce the congestion particularly in the relatively small airspace with dense traffic demand. This paper introduces a novel way that suggests flights to be delayed on the departing airports together with amount of the delays (in time) for those flights to be delayed. Adopting a fast-time simulation for predicting airspace delay of each flight for a given flight plan, the method is designed to iteratively and incrementally adjust the departure times in the plan towards reducing total airspace delays. Applying the method to Jeju airport with a hypothetically high demand, the paper demonstrates the airspace delay could be significantly reduced by applying GDP at Gimpo airport where more than 60% of Juju-bound flights departure. Although the simulation model needs to be calibrated and validated for the real-world application, the results clearly shows that the approach can possibly implemented as a tool for preparing the daily plan at the pre-tactical stage defined in the ICAO ATFM manual.
