Though the functions and operational procedures of current ACAS-II are upgraded several times owing to technical advancement, so far the mid-air collision accidents never come to an end. Recently to solve the major issues of ACAS-II, ICAO began to develop a future ACAS (Airborne Collision Avoidance System) by the year 2015. Accordingly in order to prepare for international standardization of the future ACAS, in this paper a policy is proposed for domestic implementation of the future ACAS based on the results from studying the technical standards and future development trends of ACAS.

Airlines need to reduce their greenhouse gas (GHG) emissions because of the Paris Climate Agreement and ICAO CORSIA. This examined the degree of the strategic responses to which the airlines have made and the problems in the emission trading system (ETS). According to the analysis, the total amount of emission all the airlines made in the last three years was 116% more than the emission allowance imposed by the central government resulting in 10.7 billion KRW additional emission expense. Airlines would also face an increased carbon cost due to the implementation of ICAO CORSIA by purchasing an additional paid-in emission allowance in international routes. Although it is effective to retire the old aircraft early and induce the brand-new fuel-efficient aircraft to reduce GHG emissions, it is impractical in the short-term due to the tremendous amount of investment. To reduce the emission, airlines are washing engines, using ultra-light ULD and carts in the cabin, increasing the use of flaps and preventing the use of APU. On the other hand, these are very limited measures for reducing emissions according to the ICAO's mandatory emission target.

The 6th Worldwide Air Transport Conference was held in Montreal in March 2013 under the auspices of ICAO. This conference, which has been held every ten years, is dealing with virtually every issue of international air transport, and aiming at updating ICAO policy in order to ensure long-term growth of international civil aviation. Last conference which took place in 2003 focused on the liberalization of air transport, and the 6th conference shifted its focus from whether to push for liberalization, to how to implement it. The main agenda items for the 6th conference was liberalization, safeguards, ownership, fair competition, airports and air navigation facilities, charges, and ICAO policy. The liberalization, and in particular progressive liberalization has been a main theme over the past decades. In the process leading to liberalization, there needs to be the expansion of market access, easing regulation on ownership and control of airlines. Furthermore, the provision of enough infrastructure such as airport and air navigation facilities may be contributing factor to remove impediments to liberalization. However, out of concern as for undermining interests of consumer and the weak, when liberalization is proceeding in a sudden and radical manner, there should be safeguards so as to ensure market participation by developing countries, consumer protection, and economical and transparent decision on taxes and charges. Fair competition which differs from promoting competition in the market, is a policy in order to protect the weak players and consumers from monopoly and oligopoly. The Korean delegation submitted 3 WPs (WP/85, 86 and 87) and 1 IP, and presented WPs, at the conference, which were a lot compared with previous occasions. A paradigm shift was emphasized to expedite the process of liberalization at the 6th conference. The reality is that with many previous recommendations to stress the importance of liberalization, and to urge States to change their attitudes, the pace of the liberalization has been very slow and staggering. The liberalization of air transport will contribute to the growth of air transport and related industry, to create new employment, promoting tourism and regional development, and further to facilitating mutual understanding and exchange, which will also lead to making a barrier-free world. In this context, it is expected that the next conference will also evaluate the on-going process of liberalization.

In recent years, greenhouse gas (GHG) reduction has become high priority issue in international aviation. GHG emissions from the aviation sector only accounts for approximately 2 percent of total GHG emissions in the world. However, as with GHG gases in other sectors, it has been pointed out as a contributing factor to global warming and there is an ongoing conversation in the aviation community to establish international framework for emissions reductions. In the case of international aviation, effects of aviation activities of a State go beyond the airports and airspace of that State. This makes compiling of GHG emissions data very difficult. There are also other legal and technical issues, namely the principle of “Common but Differentiated Responsibility (CBDR)” under the United Nations Framework Convention on Climate Change (UNFCCC) and “Fair Opportunity” principle of the Chicago Convention. For all these reason, it is expected that it will not be an easy job to establish an internationally agreed mechanism for reducing emissions in spite of continuing collaboration among States. UN adopted the UNFCCC in 1990 and the Kyoto Protocol in 1997 to impose common but differentiated responsibility on emissions reductions. In international aviation, ICAO has been taking the lead in measures for the aviation sector. In this role, ICAO held the High-level Meeting on International Aviation and Climate Change on 7 to 9 October 2009 at its Headquarters in Montreal and endorsed recommendations on reducing GHG from international aviation which will also be reported to the 15th Meeting of the Conference of the Parties (COP15). Key items include basic principle in global aviation emissions reduction: aspirational goals and implementation options: strategies and measures to achieve goals: means to measure and monitor the implementation; and financial and human resources. It is very likely that the Republic of Korea will be included among the Parties subject to mandatory limitation or reduction of GHG emissions after 2013. Therefore, it is necessary for Korea to thoroughly analyze ICAO measures to develop comprehensive measures for reducing aviation emissions and to take proactive actions to prepare for future discussions on critical issues after COP15.
