  • In modern international law, the absence of legal definition regarding drone(Unmanned Aerial Vehicle) has made legal scholars work on an typical analogy between aircraft codified in the international document and drone. The wording of the Convention on International Civil Aviation is limited to two categories of aircraft, such as civil aircraft and state aircraft, whereas military aircraft is not legally defined. As such it is, the current practices of the State regarding the drone flight over foreign territory have proven a hypothese that drone is being deemed as military aircraft. Principal usage of drone lies in reconnaissance and surveillance mission as well as so-called targeted killing, which is prohibited if the killing is treacherous. Claimed war against terrorism, however, is providing a legal rationale that targeted killing is not treacherous, and that the targeted person is not civilian but combatant. In such context, armed attack of drone is deemed legal and justified. Consequently, such attack is legal in the general context of the war. The rules that govern targeting do not turn on the type of weapon system used, and there is no prohibition under the laws of war on the use of technologically advanced weapons systems in armed conflict so long as they are employed in conformity with applicable laws of war. Drones may present interesting new challenges because of their sophistication and the technological advantage they convey to their operators.

  • An amendment to Japanese Civil Aeronautics Act came into effect December 10, 2015. The Act prohibits flying drones over residential areas or areas surrounding an airport without permission from the Minister of Land, Infrastructure and Transportation. Flying drones during night time and during an event is also prohibited. The term "UAV" or "UA" means any aeroplane, rotorcraft, glider or airship which cannot accommodate any person on board and can be remotely or automatically piloted (Excluding those lighter than a certain weight (200 grams). Any person who intends to operate a UAV is required to follow the operational conditions listed below, unless approved by the Minister of Land, Infrastructure, Transport and Tourism; (i) Operation of UAVs in the daytime, (ii) Operation of UAVs within Visual Line of Sight (VLOS), (iii) Maintenance of a certain operating distance between UAVs and persons or properties on the ground/water surface, (iv) Do not operate UAVs over event sites where many people gather, (v) Do not transport hazardous materials such as explosives by UAV, (vi) Do not drop any objects from UAVs. Requirements stated in "Airspace in which Flights are Prohibited" and "Operational Limitations" are not applied to flights for search and rescue operations by public organizations in case of accidents and disasters. This paper analyzes some issues as to regulations of UAVs in Korean Aviation Safety Act by comparing the regulations of UAVs in Japanese Civil Aeronautics Act. This paper, also, offers some implications and suggestions for regulations of UAVs under Korean Aviation Safety Act.

  • Unmanned aerial vehicles(UAVs) operating in the military for various purposes are designed to transmit information collected according to the purpose to GCS(Ground Control System), and to transmit/receive the vehicle's operational control and status information using wireless communication(or datalink). Currently, the military UAV systems in operation in Korea use unique communication methods, protocols, and message structures for each system. In this paper, we analyze the TM/TC data protocol of two types of military UAV systems currently under development and propose a more efficient TM/TC message design scheme in wireless communication(or datalink) environment. And we will discuss issues to be considered for standardization of technology for ensuring interoperability with many UAVs or newly introduced UAV systems.

  • Currently, the domestic UAS technology is lagging behind the leading countries in terms of both advanced technology and industrial competitiveness, but it cannot avoid the global efforts of integrating UAS into existing manned aviation system and applying them to industries. UAS is a relatively new system to existing aviation world, but ICAO is making a great effort to help Contracting States and the aviation industries to better understand and promote UAV systems. In particular, the UAS is classified as RPAS and other UAS, leading to the standardization work for integrating the RPAS into the manned aviation in the near future. For this purpose, ICAO has been promoting the standardization for the global operation of the RPAS, and in this study, it has been carrying out the study on the strategy to establish the domestic RPAS certification system including the ICAO standardization activities. This paper analyzes the domestic and international regulatory frameworks for RPAS and presents a strategy for building the domestic RPAS certification system.

  • Al-Qaeda follower who planned to attacks the Pentagon and the Assembly by unmanned aircraft equipped with explosives was caught in the dictionary in September 2011. In addition, high-performance unmanned aerial vehicles in the United States 'sentinel' of the technology being leaked to Iran in late 2011 was an accident. Terrorist attacks on the forces used unmanned aircraft will be the day the not too distant. The purpose of this research is to provide response plans against acts of terrorism utilizing unmanned aircrafts to prevent large losses of lives such as the terrorist attacks of September 11. Discussing in detail, this research suggests revising and newly implementing the definition and categorization of unmanned aircrafts as well as relevant punishment in current aeronautics regulations as an initial response against acts of terrorism utilizing unmanned aircrafts. This is in order to newly implement and revise current relevant regulations that inadequately address the rapidly developing and changing unmanned aircrafts which will lead to increased sense of alarm for the potential terrorists, and also to introduce a systematic tool to punish those who commit such acts by clearly establishing the grounds for punishment. Also, under the binary operating system over airspace currently implemented globally, it is impossible to identify and control the infiltration of airspace by unmanned aircrafts. Recognizing such limitations, this research suggests a combined operation of airspace for unmanned and manned aircrafts as a second way of response for acts of terrorism utilizing unmanned aircrafts. A systematic integrated operation of airspace will appropriately control unmanned/ manned aircrafts that were not previously reported or otherwise have deviated from navigation routes, and will be able to prevent terrorism attempts utilizing aircrafts beforehand.

  • Nowadays, major advanced countries in aviation technology are putting their effort to develop commercial and civil Unmanned Aircraft System(UAS) due to its highly promising market demand in the future. The market scale of commercial and civil UAS is expected to increase up to approximately 8.8 billon U.S. dollars by the year 2020. The usage of commercial and civil UAS covers various areas such as remote sensing, relaying communications, pollution monitoring, fire detection, aerial reconnaissance and photography, coastline monitoring, traffic monitoring and control, disaster control, search and rescue, etc. With the introduction of UAS, changes need to be made on current Air Traffic Management Systems which are focused mainly manned aircrafts to support the operation of UAS. Accordingly, the legislation for the UAS operation should be followed. Currently, ICAO's Unmanned Aircraft System Study Group(UASSG) is leading the standardization process of legislation for UAS operation internationally. However, some advanced countries such as United States, United Kingdom, Australia have adopted its own legislation. Among these countries, United States is most forth going with President Obama signing a bill to integrate UAS into U.S. national airspace by 2015. In case of Korea, legislation for the unmanned aircraft system is just in the beginning stage. There are no regulations regarding the operation of unmanned aircraft in Korea's domestic aviation law except some clauses regarding definition and permission of the unmanned aircraft flight. However, the unmanned aircrafts are currently being used in military and under development for commercial use. In addition, the Ministry of Land, Infrastructure and Transport has a ambitious plan to develop commercial and civil UAS as Korea's most competitive area in aircraft production and export. Thus, Korea is in need of the legislation for the UAS operation domestically. In this regards, I personally think that Korea's domestic legislation for UAS operation will be enacted focusing on following 12 areas : (1)use of airspace, (2)licenses of personnel, (3)certification of airworthiness, (4)definition, (5)classification, (6)equipments and documents, (7)communication, (8)rules of air, (9)training, (10)security, (11)insurance, (12)others. Im parallel with enacting domestic legislation, korea should contribute to the development of international standards for UAS operation by actively participating ICAO's UASSG.

  • UAV-UGV teaming concept has been proposed that can compensate for weak points of each platform by providing carrying, launching, recovery and recharging capability for the VTOL-UAV through the host UGV. The teaming concept can expand the observation envelop of the UGV and extend the operational capability of the UAV through mechanical combination of each system. The spherical-shaped coaxial rotorcraft UAV is suggested to provide flexible and precise interface between two systems. Hybrid navigation solution that included vision-based target tracking method for precision landing is investigated and its experimental study is performed. Feasibility study on length-variable rotor to provide the compact configuration of the loaded rotorcraft platform is also described.

  • It is imperative to examine the regulatory trends of leading overseas aviation authorities to accelerate the effort to integrate emerging new air vehicle concepts such as UAS and eVTOL into the existing national airspace system. Whilst EASA seems to react swiftly in relation to regulatory framework by proposing new sets of customised special conditions to cope with a growing demand to introduce new aircraft concepts, understanding of such movement lags behind mainly due to the complexity of EASA's regulation structure, not to mention EU's legal system. Witnessing this situation, this paper reviewed the legal system of the EU which forms the basis of EASA's regulation system together with its own recently published UAS regulations so as to contribute towards the improvement of the aviation regulatory framework.
