In this paper, we propose a secure alternative for improving airspace capacity of Incheon International Airport. Since the direction of simultaneous independent approaches to runway 15/16 radar-guided approach for ILS approach procedures for the need to provide control services, in view of the radar is the smallest possible no-fly zone airspace propose the demilitarized zone (P-518) adjustment. If possible simultaneous independent approaches to secure a temporary increase in the holding area due to traffic, the military training airspace gradually secured a total of 10 miles by 5 miles, some military training airspace in Osan Approach Control is proposed to include in Seoul Approach Control.

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.

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.

In this study, considerations for establishing RVSM airspace and requirements for RVSM operating aircraft are verified. The purpose of RVSM is to reduce vertical separation minimum for aircraft which operate between FL290~FL410 inclusive in regional airspace, and to increase airspace capacity by providing additional flight levels. To introduce RVSM, it is necessary to estimate quantatively airborne collision risk due to the reduction in vertical separation minimum. Aircraft operating through RVSM airspace is required to verify that height keeping performance is above specific standards.

This paper discusses the qualification criteria for international hub airport and suggests the strategies for Inchon International Airport (IIA) to be the hub airport in the East Asia. Recently, many East and Southeast Asia countries have invested on large scale international airports like Chap Lak Kok airport, Pudong airport etc.. as Korea have done on IIA. IIA to be open in 2001 will face a serious competition with these airport. Being a hub airport requires geographic proximity. sufficient volume of local traffic. uncongested infrastructure, a good accessibility to surrounding industrial centers. high quality of service to the airline. In order to promote airlines to land at IIA. Korea Government need to establish Open Sky Policy to many countries and national flag carriers of Korea need to be involved in a global alliance. Developing vicinity of IIA as free trade zone will generated more local traffic which makes IIA as more attractive candidate for airlines. The Korea airspace is one of the most restricted area in the world becuase of the national security. which limits civil aircraft maneuvers. The airspace need to be re-structured to exploit the full capacity of IIA.

The purpose of air traffic flow management is to balance demand and capacity in the national airspace, and its performance relies on an accurate capacity prediction of the airport or airspace. This paper developed a regression model that predicts the number of aircraft actually departing and arriving in a terminal maneuvering area. The regression model is based on a boosting ensemble learning algorithm that learns past aircraft operational data such as time, weather, scheduled demand, and unfulfilled demand at a specific airport in the terminal maneuvering area. The developed model was tested using historical departure and arrival flight data at Incheon International Airport, and the coefficient of determination is greater than 0.95. Also, the capacity of the terminal maneuvering area of interest is implicitly predicted by using the model.

The continuous increase in air traffic emphasizes the importance of capacity calculation. Research on the calculation method of Terminal Control Area (TMA) capacity has been treated as a partial aspect of the airspace sector capacity or has been limitedly studied. This study aims to propose a mathematical model for calculating TMA capacity, taking into account the Standard Terminal Arrival Route (STAR), separation standards, TMA entry speed, and runway threshold passing speed. The proposed model has the advantage of being able to calculate the instantaneous arrival capacity, which has not been noted in previous studies, along with the throughput. Additionally, it is meaningful as the model can easily calculate the arrival capacity of the TMA considering airport construction, runway expansion, or new procedures.

The purpose of RVSM is to reduce vertical separation minima for aircrafts which operate between FL290- FL410 inclusive in regional airspace, and to increase airspace capacity by providing additional flight levels. In order to introduce RVSM, it is necessary to estimate quantitatively airborne collision risk due to the reduction in vertical separation minimum. In this study, the basic concept of RVSM safety assessment and Reich collision risk model are introduced and mid-air collision risk in Incheon FIR is estimated based on ICAO RVSM safety assessment technique and Reich Model.

In domestic airport planning, capacity assessment traditionally focuses on comparing demand forecasts with runway capacity to identify saturation periods, which overlooks operational characteristics. Even when demand does not exceed capacity, prolonged near-capacity utilization can cause significant operational issues. Therefore, it is crucial to consider operational characteristics in capacity assessments to ensure stable airport operations and efficient development planning. This study uses the Capacity Coverage Chart to analyze the operational characteristics of Incheon Airport and major international airports. Based on the analysis, it suggests improving airspace and air traffic control procedures and utilizing off-peak hours to enhance operational efficiency at Incheon Airport. However, due to geopolitical constraints, increasing operational capacity at Incheon Airport is challenging. Thus, continuous efforts to expand infrastructure are necessary to meet future demand and prevent facility saturation.

Due to rapidly increasing air traffic congestion and airspace restrictions, the International Civil Aviation Organization (ICAO) is urging all aircraft to use SBAS by 2025, in order to implement Performance-based navigation to increase airspace capacity. In line with this, research and development of Korean-style SBAS, which reflects the characteristics of Korea's airspace environment, continues in Korea. Since there is no flight inspection procedure for performance testing and verification of SBAS in Korea yet, this paper analyzes FAA, ICAO Regulations, and laws enacted by the Ministry of Land, Infrastructure and Transport to derive essential evaluations and parameters of Korean SBAS, and presents the optimal design using RTK-DGPS as a position fixing system.
