After analyzing each procedure from standard instrument procedures used at Incheon International Airport, which is believed to have caused noise problems in and around Ganghwa island, we came to a conclusion that some Standard Instrument Departure Procedures and Standard Instrument Approach Procedures need to be revised, and therefore we made some propositions with regard to noise abatement procedures(CDA, RNAV approach etc.). Additionally, we evaluated viability of the proposed flight procedures by conducting a number of demonstrations with use of flight simulation.

Recently, domestic small airport development plans are being promoted centering on islands, and among them, Baengnyeong Island Airport is located very close to North Korea due to its geographical characteristics. In particular, since it is located in the P-518, which is prohibited airspace, it is essential to configure the arrival/departure flight procedure route similarly to the current ship in terms of securing flight safety. Therefore, in this study, a plan for airport location and facility scale was proposed by focusing on the runway operated for the purpose of aircraft operation through consultations with the Ministry of National Defense. It was proposed to meet the standards of the Airport Facility Act as an airport dedicated to domestic flights for airside facilities such as runway length and direction, target aircraft, landing pad, apron, runway and taxiway width appropriate for the topographical characteristics of Baengnyeong Island. As a result, the flight procedure is generally established as a two-way visual flight, but the 10-way arrival/departure procedure was planned to be changed to an instrument (non-precision) according to the specificity of the region. In addition, a flight procedure was established and presented for safe and systematic operation by reflecting the changes in airport facility size (landing pad, runway end safety area, etc.) following the change in instrument flight procedure in the visual flight procedure.

In case of KOREA, many difficulties are expected for pilots to adapt to the flight operational environment changes which we will meet suddenly in anytime of the future as the operating plan for GPS is not fully prepared yet. It is because GPS operation is rather difficult compared to other navigation equipments, and it takes much time and experience to be familiar with GPS instrument approach procedure. First of all, it is keenly required to establish GPS instrument approach procedure for the local airports to be familiar with GPS instrument approach procedure. We would like to introduce GPS instrument approach procedure for the Cheju International Airport as a basic model to help you to understand it.

In this study. differences in attention allocation patterns between expert and novIce pilots were investigated by a verbal protocol when pilots were engaged in a task during the instrument flight. Ten pilots including experts and novices were participated to conduct a pre-determined task(a fix-to-fix) on F-5E Cockpit Procedure Trainer Simulator. Experts show better performance as expected with more stable variations in speed. altitude. and attitude. In attention allocation patterns. novices allocated about 83% of attentional resources on the primary instruments (airspeed indicator. altitude indicator. and attitude) relating to the task of the basic flight while experts spent 57%. This difference in the availability of attentional resources allowed expert pilots to accomplish the task better than novices. In other words. training a pilot should consider a program for building up wider instrument scanning patterns to become an expert in a shorter time.

Risk assessment should be processed when physical circumstances of airspace such as establishment of new flight procedures or reconstruction of existing airspace are planned to change and one of the alternatives for the change have to be selected. This is an effort to find the best alternative which is able to maintain at or above the acceptable risk level. ICAO and its contracting states provide specialized guidance material for 'Safety Management System' relating to handing airspace matters. These manuals include a conceptual framework for managing safety as well as some of the systemic processes and criteria used to meet the objectives of a State's safety programme. This criteria must be established in compliance with the State's laws and regulations for air safety and for the fulfillment of the State's safety goals. This study is to carry out the risk assessment criteria through literature reviews relevant to the safety management, and to propose the results of criteria to be applicable for establishing flight procedure design process.

대부분 국가에서 계기비행 절차는 국제민간항공기구(ICAO)의 DOC 8168, 항행 서비스 및 운항 절차(PANS-OPS) 또는 미국 연방항공청(FAA)의 터미널 절차(TERPS) 중 한 가지 기준을 적용해 설계된다. 특히, 선회접근 절차는 두 기준이 서로 많은 차이를 갖고 있고, 미국 터미널 절차(TERPS)는 2013년 이후에는 고도에 따라 확장된 기준을 적용함으로써 더 복잡해졌다. 선회접근 절차는 착륙을 위해 항공기를 에너지가 낮은 상태에서 지면과 가깝게 기동하는 것을 포함하므로 직진접근 절차보다 더 위험에 노출된다. 본 연구에서는 이들 차이점을 정확하게 알기 위해 선회접근 절차가 국내의 개별 공항에 따라 어떤 기준에 의해 설계되었는지를 구분하고, 선회접근 기동 중 최소장애물 회피를 보장하는 선회접근 구역 범위를 위한 반경을 산출하고, 안전한 선회접근 절차 수행을 위한 방법을 제시한다.

'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.

현재 대부분의 공항에서 운용중인 계기착륙시스템 (ILS; instrument landing system)은 시스템 특성상 단일경로로 운영되어, 다수의 항공기를 수용하기에는 한계가 있다. 이러한 한계점을 해결하기 위해 GNSS를 이용한 위성항법시스템인 GBAS가 개발되었다. GBAS는 ILS 보다 위치 정확도도 높고 단일경로가 아닌 다수의 경로를 이용하여 착륙이 가능하기 때문에, 다양한 착륙절차를 수행할 수 있다. 이에, 본 논문에서는 환경적인 요건과 공역 제한 때문에 ILS 설치가 불가피한 태안비행장에 가상 ILS 절차를 수립한 후 cessna skyhawk 172를 이용하여 가상 ILS 절차와 curved approach 절차를 비교하는 비행시험을 하여 curved approach에 대한 장점을 확인 하였다.

In response to the recent surge in aviation demand, major airports and aviation authorities continue to make efforts to formulate arrival and approach procedures that take into account efficient aircraft separation, noise and environmental issues of carbon (CO2) emissions. In order to ensure efficient traffic control and environmental issues, as a result, a new concept Trombone, Point Merge, etc. have been introduced and widely used in the domestic airspace. However, these new concept procedures which do not properly reflect the characteristics of the aircraft operation performance and the FMS vertical descent guidance hinder flight efficiency as well as bring in turn negative factors such as level-off flight and the use of drag device at the busiest phase of the flight descent operation, like the Continuous Descent Operation (CDO). Accordingly, throughout modification the current Standard Terminal Arrival Route (STAR) and Instrument Approach Procedure(IAP) that reflect the aircraft descent performance and the FMS guidance, the flight operation safety and efficiency is expected to be improved eventually. We herewith analyze and propose the way of improving flight efficiency in the arrival operation procedure by supplementary modification which consequently contribute to the aviation industry international competitiveness.
