The airspace has to be designed considering the flight safety and economic efficiency of aircraft operators. The International Civil Aviation Organization(ICAO) published standards and recommended practices for safe design of the airspace. Each contracting country must follow the ICAO standards in designing the airspace for the utilization of civil aviation. Normally each member establishes its own standards and national aviation law for the safe and efficient design of the airspace, regarding the ICAO standards. However, our government has not developed yet clear and detailed standards and regulation system for airspace design. This might lead to aviation accidents and disputes between operators of aviation system This study is to review the characteristics of ICAO standards and a legal problem related to application of international standards for airspace design. Specifically this research analyzed the case of airspace design and operation of a domestic airport. The results of analysis are as follow: (1) per the safety of civil aviation, it is very required to establish national regulation system to follow ICAO standards in designing airspace, (2) It is also necessary to establish separate procedure for civil aircraft in military air base, when the aerodrome is co-used by military and civil aircraft. If the same procedure for military aircraft is applied to civil aircraft, it is necessary to make clear what the design concept is, (3) and the differences from ICAO standards have to be publicly known.

The Automatic Dependent Surveillance Broadcast (ADS-B) system is a key component of CNS/ATM recommended by the International Civil Aviation Organization (ICAO) as the next generation air traffic control system. ADS-B broadcasts identification, positional data, and operation information of an aircraft to other aircraft, ground vehicles and ground stations in the nearby region. This paper explores the ADS-B based trajectory prediction and the conflict detection algorithm. The multiple-model based trajectory prediction algorithm leads accurate predicted conflict probability at a future forecast time. We propose an efficient and accurate algorithm to calculate conflict probability based on approximation of the conflict zone by a set of blocks. The performance of proposed algorithms is demonstrated by a numerical simulation of two aircraft encounter scenarios.

The instrument landing system (ILS) is an international standard established by the International civil aviation organization (ICAO) as one of the landing support facilities for aircraft. This system consists of a localizer (LOC) that provides orientation information about the runway to indicate the approach direction, a glide path (GP) that indicates the appropriate approach glide slope, and three of marker beacons (MB) that indicates the distance to the runway landing edge. In this study, we predicted the received signal strength by altitude and distance for LOC signals transmitted from the ground and analyzed the difference with the signal strength measured in the actual environment. Our objective is to develop signal strength prediction technology and apply it to the real environment.

Charter flight in international air law has, from very beginning, not precisely defined by the International Civil Aviation Organization (lCAO) since 1947 when it came into being. By practice, the operation of charter traffic is, in its very beginning, the subject to the regulations of national rules and bilateral charter agreements (charter annex clause) within the framework of normal bilateral agreement of international air services. Taiwan had signed a series of bilateral air service agreement under the name of the Government of the Republic of China when Taiwan was recognized by the United Nations and major members of international community as the sole legal government representing China before 1971, but that situation was changed since then. Taiwan has only maintained diplomatic relations with 25 States, but maintained semi-official relations with major powers of the world. The former agreements were signed within the framework of the Vienna Convention on the Law of Treaties of 1969 while the latter agreements were signed within the framework of administrative and civil law of two countries which were not in the form of bilateral treaty signed by two sovereign States in its proper sense of international law. The legal regime of charter flights between Taiwan and Mainland China is regulated by special arrangements negotiated by delegated airlines and airlines association or private law institutions.

Purpose - This study will investigate and identify the relationship between brand image, brand attitude and intent to purchase based on subjects that have remembered or watched more than one storytelling marketing ad related to airlines. The purpose of the project is to secure market competitiveness by presenting the basis for and use of the marketing strategy using storytelling, which can capture the goodwill of the aerospace competition market in the future. Research, design, data, and methodology - Prior to the research model and hypothesis testing phase, a verification factor analysis was conducted to assess internal consistency among each measurement item and to ensure reliability and validity of the measurement tool. Further, the organization was assessed for validity by calculating the mean variance estimation (AVE) and the construction concept reliability (CCR) through a positive factor analysis. Hypothesis verification was analyzed through a structural equation model, and each concept set in the hypothesis was entered as a potential variable, and each measurement item was entered as an observation variable. Results - Airline's storytelling marketing has a significant impact on the brand image and two emotional and cognitive responses have been shown to influence the brand image. In addition, airline storytelling marketing has a significant impact on brand attitudes and airline storytelling marketing derived from factor analysis has shown two emotional and cognitive responses to brand attitudes. Conclusions - The parts derived based on the research results show that storytelling marketing has a strong influence on the airline's brand image and attitude, and that it is necessary for airlines to have a brand image and attitude. Also, forming a favorable brand image has a significant impact on brand attitudes. We believe that by presenting basic data to the aviation industry in future research on airline storytelling, we will be able to increase understanding and contribution to development of storytelling marketing in aviation.

A Flight test is an important process that must be performed to maintain airworthiness in the aircraft lifecycle, including aircraft development and certification. Flight test can be conducted for the purpose of demonstrating or verifying compliance with the applicable standard. Results of the flight test air accident analysis confirm that it is caused by a combination of various factors as well as aircraft. The International Civil Aviation Organization recommends the establishment and implementation of a safety management system to prevent aircraft accidents, but it does not reflect the specificity of the flight test. As such, advanced countries are providing separate criteria to assist stakeholder in conducting flight test safety management. This study investigates and analyzes relevant regulations of advanced countries, in accordance with the construction of a national flight performance test site in Korea, and proposes government-level guidelines to help stakeholders develop their flight test operation manuals. The guidelines discuss topics such as organizational composition, safety and risk management, flight operation, personnel management, and administrative issues.

Aeronautical Information Service means a service established within the defined area of coverage responsible for the provision of aeronautical information/data necessary for the safety, regularity and efficiency of air navigation. Especially, in consequence of RNAV envelopment, the role and importance of aeronautical information/data has been increased constantly, therefore advanced RNP and navigation systems has been highly required simultaneously. International Civil Aviation Organization establishes SARPs to maintain aviation safety for every contracting states. Therefore, every contracting states should make an application of the aviation information and data in accordance with ICAO's SARPs, but each state is actually applied with each other regulations considered with each state's circumstance. At the result of these reason, it sometimes makes confuse to aircraft operator and effects significant aviation safety. The purpose of this study is to investigate SARPs of Annexes and rules of FAA relevant to Aeronautical Information Service(AIS), to compare them with Korean Aviation law and regulations related to AIS and then, to provide information for planing and decision-making to enhance them into the international standards.

VHF Omnidirectional Radio range(VOR) is used as an aircraft navigational aid. The VOR is a short-range air navigation system providing aircraft with its bearing relative to the ground station. The accuracy of a VOR must be checked in accordance with the current ICAO, FAA and domestic regulations. The primary purpose of performing VOR station ground checks is to minimize the need for expensive flight checks by determining the amount and direction of any course bearing inaccuracies being transmitted. In this paper we present current and advanced way of monitoring of VOR system. We verify this way by field test of the monitoring and it is a high performance way to achieve an improvement in accuracy and an effect compared to present monitoring system.

The purpose of this study is to verify the stable flight conditions of drones within a limited urban area by using the ICAO(International Civil Aviation Organization) reich model which is using to evaluate civil aircraft stability. The results of the study are summarized as follows. First, in order for the drones flying stably, the horizontal safety separation distance between a drone and another should be at least 1,852M. Second, assuming that no obstacles within 1,852M of horizontal space, two drones can be fly into upper and lower spaces. However there are obstacles such as buildings, it is impossible to secure a 1,852M distance between drones. Third, sensitivity analysis point out that the separation interval($s_x$) of drone aviation has the greatest influence on the TLS(Target Level of Safety). If future research is conducted to lower the numerical values, the safety distance between a drone and another drone will be drastically reduced, allowing more detailed urban space division, and will be presented as a scientific numerical value for establishing a dedicated path for the drones.
