In the existing air traffic management (ATM) system, various types of safety alert features are provided based on trajectory data to ensure the safety of aircraft operations, along with aircraft position and detailed flight information. The urban air traffic management (UATM) system for urban air mobility (UAM) should also provide safety alert features to ensure the safety of UAM operations. Considering the operational environment of UAM, it is necessary that the safety alert features provided at least match or exceed those available in the existing ATM system. This study aims to present the safety alert features of the new UATM system that differ from those provided by the existing ATM system before introduction and commercialization of UAM. The study was conducted focusing on the safety alert features that should be provided in the event of a deviation from the UAM's path, and the establishment of the safety alert features was carried out in two parts: approach path monitor (APM), which is applied during the approach phase, and route adherence monitoring (RAM), which is applied during the cruise phase.

The European civil aviation industry, which had lower technical skills, capital strength and market scale than the U.S., adopted the production system of joint development and division labor between the nations of Europe. Each plant locations strengthened their specialization of the production branch in the past 40 years with a geographical accumulation of the specialized manufacturing facilities, suppliers, universities and laboratories by the logic of geographical proximity and learning effect. The cargo plane transportation system in the production of short- and medium-haul aircraft facilitated the geographical dispersion of manufacturing process and the logistical linkage among the various plant locations. But the production of long-haul large aircraft(A380) chosen the transportation system by the cargo ship because of the size and weight. Considering the transportation system by the cargo ship, the choice of Toulouse as a final assembly plant location was the irrational locational decision from a locational point of view. This locational choice is explained by the merging process of the European civil aviation industry, the logic of learning effect and geographical proximity, and the active attraction support policy.

지난 5월 1일부로 동유럽 10개국이 유럽연합(EU)에 가입했다. 동유럽 10개국이 EU에 가입했다는 것은 두 가지 측면에서 역사적 장애물을 제거하는 계기가 될 것이다. 하나는 사회주의체제를 벗어나 자본주의 체제로 편입되는 체제전환을 추구해왔으니 구소련이 주도하던 바르샤바동맹국으로서 몸에 베었던 의식과 체제의 잔재를 씻어내기 어려웠으며 이러한 잔재들은 동유럽 국가들의 경제$\cdot$사회 발전을 가로막는 역사적 장애요인으로 작용해 왔다. 따라서 EU가입은 이러한 역사적 장애요인을 극복하는 중요한 계기가 될 것으로 예상된다. 동유럽 10개국은 모든 사회$\cdot$경제 거래를 EU기준에 맞춰야 하며, 도로$\cdot$철도$\cdot$해운$\cdot$항공 등 물류부문에서도 EU의 기준을 충족시켜야 하는 ‘EU 공동체 확적영역’을 수용해야 한다. 따라서 동유럽 물류시장은 EU가입 이후 경제 및 교역발전에 따른 양적 팽창이외에 물류관련 기준과 거래관행이 개선되는 질적 발전도 가능하게 될 것이다. 우선 역내 통관절차가 단순해지는 등 사람, 자본, 화물의 이동이 자유화됨으로써 물동량이 크게 늘어날 것으로 예상되고 또한 동유럽 국가들은 EU로부터 운송 인프라 개발 및 현대화에 필요한 경제적 지원도 받게 된다. 한국해양수산개발원(KMI)은 ‘EU 가입 동유럽 물류시장의 특징과 시사점’이라는 현안분석을 통해 이같이 밝히고 우리나라 물류기업이 동유럽 시장에 진출하는 경우 제조업과 동반진출하고 현지업체와의 제휴관계를 모색하는 것이 바람직하다는 대응방향을 제시했다. 동 현안분석 내용을 요약$\cdot$정리한다.

A runway safety area (RSA) is defined as the surface surrounding the runway prepared or suitable for reducing the risk of damage to airplanes in the event of an undershoot, overshoot, or excursion from the runway. The Runway Stripe is a defined area including the runway stopway, if provided, intended firstly to reduce the risk of damage to aircraft running off a runway, and secondly, to protect aircraft flying over it during takeoff or landing operations. This study used 2 RSA analysis models; RSARA and LRSARA. The analysis utilizes historical data from the specific airport and allows to take into consideration specific operational conditions to which movements are subject, as well as the actual or planned RSA conditions in terms of dimensions, configuration, and boundaries defined by existing obstacles. This study applied the RSA and LRSA risk assessment models to a domestic airport that do not meet the criteria required by standards for aerodrome physical characteristics. The airport is considering a method to secure the runway strip standard through the displaced threshold. This study intends to confirm through quantitative risk estimation whether meeting facility standards through the runway displaced threshold leads to a positive change in risk mitigation.
