In this paper the new revision of Korean Airworthiness Standards (KAS) - Emissions was proposed for enforced environmental standards. The Aircraft Engine Fuel Venting and Exhaust Emissions Requirements have been only defined for smoke, HC, CO and NOx as management items in previous KAS. However, this standard has not covered the current situation that International Civil Aviation Organization (ICAO) and United States Environmental Protection Agency (EPA) enforced environmental regulations, such as emissions trading system, limitation of CO₂ emissions and restriction of exhaust gas. In order to overcome these outdated situations, we presented the new requirements for aircraft exhaust gas emissions standard of Korea based on the latest standards of United States, Europe and other countries.

The European Union(EU) has recently introduced its Directive 2008/101/EC to include aviation in the EU ETS(emissions trading system). As an amendment to Directive 2003/87/EC that regulates reduction of the green house gas(GHG) emissions in Europe in preparation for the Kyoto Protocol, 1997, it obliges both EU and non-EU airline operators to reduce the emission of the carbon dioxide(CO2) significantly in the year 2012 and thereafter from the level they made in 2004 to 2006. Emission allowances allowed free of charge for each airline operator is 97% in the first year 2012 and 95% from 2013 and thereafter from the average annual emissions during historical years 2004 to 2006. Taking into account the rapid growth of air traffic, i.e. 5% in recent years, airlines operating to EU have to reduce their emissions by about 30% in order to meet the requirements of the EU Directive, if not buy the emissions right in the emissions trading market. However, buying quantity is limited to 15% in the year 2012 subject to possible increase from the year 2013. Apart from the hard burden of the airline operators, in particular of those from non-European countries, which is not concern of this paper, the EU Directive has certain legal problems. First, while the Kyoto Protocol of universal application is binding on the Annex I countries of the Climate Change Convention, i.e. developed countries including all Member States of the European Union to reduce GHG at least by 5% in the implementation period from 2008 to 2012 over the 1990 level, non-Annex I countries which are not bound by the Kyoto Protocol see their airlines subjected to aircraft emissions reductions scheme of EU when operating to EU. This is against the provisions of the Kyoto Protocol dealing with the emissions of GHG including CO2, target of the EU Directive. While the Kyoto Protocol mandates ICAO to set up a worldwide scheme for aircraft emissions to contribute to stabilizing GHG concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system, the EU ETS was drawn up outside the framework of the international Civil Aviation Organization(ICAO). Second, EU Directive 2008/101 defines 'aviation activities' as covering 'flights which depart from or arrive in the territory of a Member State to which the [EU] Treaty applies'. While the EU airlines are certainly subject to the EU regulations, obliging non-EU airlines to reduce their emissions even if the emissions are produced during the flight over the high seas and the airspace of the third countries is problematic. The point is whether the EU Directive can be legally applied to extra-territorial behavior of non-EU entities. Third, the EU Directive prescribes 2012 as the first year for implementation. However, the year 2012 is the last year of implementation of the Kyoto Protocol for Annex I countries including members of EU to reduce GHG including the emissions of CO2 coming out from domestic airlines operation. Consequently, EU airlines were already on the reduction scheme of CO2 emissions as long as their domestic operations are concerned from 2008 until the year 2012. But with the implementation of Directive 2008/101 from 2012 for all the airlines, regardless of the status of the country Annex I or not where they are registered, the EU airlines are no longer at the disadvantage compared with the airlines of non-Annex I countries. This unexpected premium for the EU airlines may result in a derogation of the Kyoto Protocol at least for the year 2012. Lastly, as a conclusion, the author shed light briefly on how the Korean aviation authorities are dealing with the EU restrictive measures.

국내 전체 조종사 배출 인원은 연 평균 1,200여명을 훌쩍 넘긴 가운데, 이 중 항공기사용업체를 통해 배출된 조종사 인원은 최근 5년 사이 2~3.5배 이상의 증가추세를 보이며 약 650여명 이상을 배출함으로써 전체 인원의 반 이상을 차지하고 있다. 그러나 현행 법령은 비행훈련과정을 운영하는 대학을 포함하여 항공기사용사업의 업무영역을 고려한 등록 요건 및 안전 고려가 부족하며, 비행훈련은 미래의 조종사를 양성하는 중요한 영역임에도 불구하고 훈련프로그램에 관한 요건이 규정되지 않아 비행안전은 물론, 양질의 조종사 인력양성을 위한 제도적 장치가 부족한 상황이다. 본 연구는 최근 발생한 항공기 사고/준사고 및 안전장애 유형을 토대로 항공기사용사업체에 대해 분석하고, 시행중인 비행훈련에 대한 법과 제도, 안전관련 개선방안에 대해 살펴보고자 한다.

The potential impact of aircraft emissions on the current and projected climate of our planet is one of the more important environmental issues facing the aviation industry. Increasing concern over the potential negative effects of greenhouse gas emissions has motivated the development of an aircraft emission estimation and prediction system as one of the ways to reduce aircraft emissions and mitigate the impact of aviation on climate. Hence, in this research, using Piano-X software which was developed by Lissys Co., fuel consumption and emissions for 3 types of aircraft were estimated for different design payloads with various flight distances and flight paths. Fuel burns for economy speed, long range cruise speed, maximum range speed were also investigated with various flight distances and altitudes.

The amount of greenhouse gas (GHG) emissions has been increasing steadily over the last 3 years (2009~2011), averaging 5.7 percent a year, due to the growth of low cost carriers and the increased demand for air transportations. The present study attempts to investigate the aviation fuel consumption and GHG emissions of Tier 3a type by the flight phase from three aircraft type such as B737-600(routes between Gimpo-Jeju airport), B737-700(routes between Gimpo-Jeju airport and Inchon-Narita), B737-800(routes between Inchon-Narita) using the Flight Operation Quality Assurance(FOQA) data of the year 2011.

The potential impact of aircraft emissions on the current and projected climate of our planet is one of the more important environmental issues facing the aviation industry. Increasing concern over the potential negative effects of greenhouse gas emissions has motivated aircraft emission estimation and prediction as one of the ways to reduce aircraft emissions and mitigate the impact of aviation on climate. We obtained airline flight schedules for all the airports in Korea that are included in OAG data. Fuel burn and emission index of LTO flight which contains take off, climb and approach under 3000ft and Non LTO flight which contains climb, cruise and descent over 3000ft for all the airports in Korea in 2005 were estimated and analysed for each condition using AEIC software which has been developed by MIT Lab for Aviation and Environment.

최근 들어 대기보전에 관한 연구와 관심의 증가로 인하여 점, 선, 면 오염원에 대한 많은 연구 결과들이 발표되어 지고 있다. 특히 지역별로 자동차, 항공기, 선박 등의 특정적인 교통수단에 따른 대기오염 배출량과 배출 특성도 많이 연구되고 있다. 그러나 아직까지 철도차량 배출원에 의한 배출량의 산정과 배출 특성에 따른 대기오염 영향에 대한 연구사례가 드물다. (중략)

포항지역은 인구규모 50만 정도의 중소도시이지만 도심은 항만을 끼고 있고 포항제철 및 연관산업체가 입지하여 선박, 전동기관차 그리고 인근의 공항 등 다양한 형태의 대기오염물질 배출원이 공존하고 있는 지역이다. 지금까지 대기오염배출량 산정에는 주로 자동차 및 산업체 및 주거지역지역과 같은 오염원을 다루고 있으며 기관차, 항공기 및 선박과 같은 오염원에 의한 대기오염물질 배출량 산정은 드물다. 이러한 복합적인 오염원이 존재하는 곳에서의 대기질 관리에 있어 가장 선행되어야 할 사항 중의 하나는 주요한 대기오염 배출원의 파악과 가장 현실성 있는 오염원의 배출목록을 작성하는 것이다.

현재 우리 나라에서는 수송분야 중 항공기, 선박, 건설기계 농기계 등과 같은 비토로 이동오염원에 의한 대기오염에 대해서는 연구가 부진한 실정이다. 2001년 김포공항을 이용하던 국제선 항공기는 인천국제공항의 개항에 따라 이전하게 되었다. 이에 따라 항공기 이착륙에 의한 대기오염 배출이 상당 부분 김포지역에서 인천 영종도지역으로 이전되었을 것으로 예상된다. 본 연구에서는 미국 FAA에서 공항의 대기오염배출량 산출 및 주변지역의 농도예측에 선정모델로 추천하고 있는 EDMS (Emission and Dispersion Modeling System)을 사용하여 국제선 이전에 따른 김포공항 주변지역의 NOx 오염도 변화를 예측하고 이를 실측치와 비교 평가하고자 한다.
