Our nation have several procedures and law for national airspace management, however those procedures and law not enough to manage airspace. Therefore, I have studied this paper for improving flight safety and for providing economics flight of civcil aircraft and military aircraft, also, for increasing efficiency of airspace through systematic airspace management, additionally, for improving nation defense ability and for preventation our nation damage when occuring airspace problem. Nowaday. in using airspace. two theory which freely use theory and use theory under jurisdiction is opposed by every nation in worldwide. Consequently. we can realize every nation endeavour to increase their jurisdiction airspace. However. our nation is not still prepared to cope with other nation when occuring airspace trouble. because airspace definition is not prescribed on our aviation law. Therefore. several problems which are improved in our airspace management are presented on this paper. The presented matters are as follows. First, The airspace definition is not prescribed on aviation law and responsibility limit of airspace management is ambugious. Second. problem on structure of approach control area and special airspace, Third. problem on airway system. Fourth. civil agency and military agency apply respectively different regulation in establishment of aircraft flight route, To grasp these problems, considered the airspace conception, airspace classfication. legal character of airspace. our nation airspace state and management together with other nation airspace state and management. also compared our nation airspace management with other nation airspace management. And. improvement methods to solve problems which was appeared by comparing and analysis are presented on this paper.

'Navigable airspace' means an airspace at and above the minimum safe flight level, including airspace or flight procedures needed for safe takeoff and landing. Airspace may be established as needed and may be abolished, and in some cases may be limited to airspace management. These are absolutely based on risk assessment. Safety is the state in which the risk of harm to persons or of property damage is reduced to, and maintained at or below, an acceptable level through a continuing process of hazard identification and risk management. 'Risk' is the assessed potential for adverse consequences resulting from a hazard and 'Risk assessment' involves consideration of both the frequency and the severity of any adverse consequence. This paper proposed 'risk assessment procedure' for the structural changes of Navigable Airspaces through literature reviews relevant to manuals on airspace management and risk management.

Global market of unmanned aircraft(UA) is rapidly expending based on the versatile and efficient utility of the UA. Domestically many industries, universities and research institutes are trying to do research and development of the UA in various angle of aspect. In spite of these effort, all the participants of research and development of the UA has been suffering the difficulty of acquiring the airspace around vicinity of Goheung airfield for the flight test of UA. Although the current procedure of execution of the flight test of UA is set after acquiring the airspace by applying the NOTAM(Notice To Air Man) to the Ministry of Land, Infrastructure and Transport(MLIT) at least 7 days before the flight test and commencing with the publication of the NOTAM by MLIT, if the flight test is carried out as planned, changing or reapplying the NOTAM expends mort time and makes difficulty often. Therefore it is needed that a restricted airspace for the flight test of UA is established and make all the executioner of flight test uses the exclusive airspace without limitation. This research proposes the restricted airspace with short term and long term establish requirement of airspace separately. The short term requirement has been established with the airspace of 10 nm radius and 8,000 ft altitude in which the requirements of flight test can be carried out more than 90% without needs of supplement of the additional airspace. The long term has been established within the airspace of 30 nm radius which is the maximum Radio Line Of Sight(RLOS) and 8,000 ft altitude with exclusion of current air way, airport control area, approaching corridor to the airport, existing restricted area(RA) and Military Operating Area(MOA) for the purpose of minimizing inconvenience of the other airspace user. Once establishing the exclusive airspace for the flight test of UA, research and development of industries, universities and research institutes will be more vigorous and contributes to the national economy.

Considering Republic of Korea that is known as the worlds one of the most compact airspace, together with development of technology of aerospace and ever-strengthening weapon systems of aircraft, is, in its reality, in a dire need for more practical infrastructure against any intrusion, of course also being mindful of the situation with the North Korea, to its national airspace or other controlled airspace. Republic of Koreas current legislative regime is unable to effectively respond to such crisis on any legal ground, and responsible government members are relying heavily on relevant military laws and regulations. Naturally, there exists strong possibility of various problems when there occurs an actual intrusion to Koreas airspace and lawful and legal resolution of the aftereffect is demanded. This article categorizes Korean peninsula and its national airspace into various kinds of airspaces; KADIZ; FIR; airspace above EEZ; airspace above contiguous zone; airspace above the high sea, and attempted to research and study these respective categories, given the unique nature of airspace and the current responsive measure. Furthermore, this article will review some of the relevant legislative actions and their sense of direction as solution to the discussed problems.

The Korean airspace is very much limited, but its users are many. Especially many special using airspaces for military aircraft are formulated within the Taegu Flight Information Region and it is so restricted for civil aircraft to use the military airspaces. However, as the demand of civil air traffic is increasing, positive cooperation among the users of the airspace is needed to cope with the demand and to uplift the utilitation of the Korean airspace. Most of airspace except airways within the FIR are restricted areas, prohibited areas or operation areas for the military purpose. This thesis shows how to improve the utilitation of the Korean airspace and how much economical benefit the suggestion gives.

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 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.

Recently airspace became a hot issue considering today's international relations. However, there was no data that could be fully explained about a legal system of korean airspace, so I looked at law and practice about korean airspace together. The nation's aviation law sector is comletely separate from those related to civil and military aircraft, at least in legal terms. The Minister of Land, Infrastructure and Transport shall carry out his/her duties with various authority granted by the "Aviation Safety Act". The nation's aviation-related content is being regulated too much by the Ministry of Land, Infrastructure and Transport's notice or regulation, and there are many things that are not well known about which clauses of the upper law are associated with. The notice should be clearly described only in detail on delegated matters. As for the airspace system, the airspace system is too complex for the public to understand, and there seems to be a gap between law and practice. Therefore, I think it would be good to reestablish a simple and practical airspace system. Airspace and aviation related tasks in the military need to be clearly understood by distinguishing between those entrusted by the Minister of Land, Infrastructure and Transport and those inherent in the military. Regarding matters entrusted by the Minister of Land, Infrastructure and Transpor, it is necessary to work closely with the Minister of Land, Infrastructure and Transport when preparing related work guidelines, and to clarify who should prepare the guidelines. Regarding airspace control as a military operation, policies or guidelines that are faithful to military doctrine on airspace control are needed.

The airspace has to be designed considering the flight safety and economic efficiency of aircraft operators. The International Civil Aviation Organization(ICAO) published standards and recommended practices for safe design of the airspace. Each contracting country must follow the ICAO standards in designing the airspace for the utilization of civil aviation. Normally each member establishes its own standards and national aviation law for the safe and efficient design of the airspace, regarding the ICAO standards. However, our government has not developed yet clear and detailed standards and regulation system for airspace design. This might lead to aviation accidents and disputes between operators of aviation system This study is to review the characteristics of ICAO standards and a legal problem related to application of international standards for airspace design. Specifically this research analyzed the case of airspace design and operation of a domestic airport. The results of analysis are as follow: (1) per the safety of civil aviation, it is very required to establish national regulation system to follow ICAO standards in designing airspace, (2) It is also necessary to establish separate procedure for civil aircraft in military air base, when the aerodrome is co-used by military and civil aircraft. If the same procedure for military aircraft is applied to civil aircraft, it is necessary to make clear what the design concept is, (3) and the differences from ICAO standards have to be publicly known.

In this paper, the design result of the trajectory-based air traffic analysis software which is going to be used to assess air-traffic efficiency in case that some modification's made in dynamic airspace configuration, is described. The software has been developed to make statistical data about air-traffic in Incheon FIR based on the RPL, and to analyze the airway utilization and controller workload using the trajectory modeling data which are derived from the aircraft type, cruise speed, cruise altitude, and routes and fixes in the RPL. Since it batch-processes the long-term trajectory data with other inputs such as airspace, route information and so on, it has the advantage of quickly predicting the traffic variation when some change in airspace and route information is made.
