  • This paper used the golf course visitors' data in Jeju region to forecast the growth of inbound air traveler to Jeju. This is because the golf course visitors were proven to bring the highest economic and production inducement effect to the Jeju region. Based on such a data, this paper forecast the short-term growth rate of inbound air traveler using ARIMA to the Jeju until December 2025. According to ARIMA (0,1,0) (0,1,1) model, it was analyzed that the monthly number of golf course visitors to Jeju has been increasing steadily even since COVID-19 pandemic and the number is expected to grow until the end of 2025. Applying the same parameters of ARIMA (0,1,0) (0,1,1) to inbound air travel data, it was found the growth rate of inbound air travelers would be higher than the growth rate of 2019 shortly without moderate variation even though the monthly number of inbound travelers to Jeju had been dropped during COVID-19 pandemic.

  • This study aims to provide information necessary for developing a "Competency-Based Training and Evaluation Plan" for general aviation flight instructors in Korea. General aviation training experts designed a survey by selecting "Behavior Indicators" from the ICAO Flight Instructor Competency Model. This study analyses the importance of Behavioral Indicators, the level of instructor performance, and the training needs for flight instructors. According to the factor analysis, ICAO "Flight Instructor Competency Model" is found as a valid tool to measure general aviation flight instructor competencies. According to the training needs analysis, flight instructors training program needs to be improved on "Training Environment Management", "Teaching Method", and "Interaction" competencies. When compared with trainee group, flight instructors & examiners have a higher training demand for "Teaching & Learning Environment Management". This study suggests the flight instructor training program requires to be reorganized based on the competencies related to the flight instructor duties in the training environments.

  • In this study, we reviewed access transportation, operating companies, and airport infrastructure to revitalize Cheongju International Airport. Regarding access transportation infrastructure, it is necessary to promote a railway network connecting the metropolitan inland line and the central inland region. In addition, active administrative support from local governments is required to ensure smooth progress in railway and highway infrastructure linkage projects, such as the Osong Connecting Line and Chungbuk Line, high-speed rail network promotion, and expansion of the Chungbuk Eastern Axis Expressway and Central Expressway. Regarding operator access infrastructure, continuous efforts are required to add and attract airlines based at Cheongju International Airport. Regarding airport infrastructure, the Cheongju International Airport runway needs complete resurfacing due to its deterioration. Domestic passenger capacity has exceeded 6.5%, and considering the increase in import and export of high value-added goods in the North Chungcheong region, it is necessary to build and expand passenger terminals and cargo terminals. Cheongju International Airport's runway does not have enough runway length to operate large and ultra-large aircraft, so if it is extended from the existing 2,744m to 456m to 3,200m, several benefits can be expected in terms of revitalizing Cheongju Airport, such as route expansion.

  • As the domestic aviation industry grows, the aviation maintenance field is also growing rapidly. This change calls for more aircraft maintenance technicians, and interest in safety accidents is also increasing. Individual safety climate indicates the importance of safety in the organization. We expect that three individual factors (training effectiveness, procedure effectiveness, and work pressure) relate to safety behavior in the workplace via individual safety climate. The purpose of this research is investigating the relationship between individual factors and aircraft maintenance technician's safety behavior. Previous studies related to individual factors were examined for literature review. Based on the previous studies, research model was constructed. Hypothesis was verified by effected data from 305 samples were employed for final survey. The results show that individual factors were meaningful factors to effect perceived safety behavior, and safety knowledge & safety motivation were related to safety compliance & safety participation.

  • Master plan plans for new airports should estimate the approximate scale of the airside's moorings and terminals. The size of the pavilion can be determined by complex factors such as the operating hours of the operating company, the frequency of operation, and the aircraft class. Among them, the number of flights is calculated using the Horon-jeff equation because of the relationship between the number of flights and the time occupied by the mains. Since this estimation formula is a simplified formula, it is necessary to verify the appropriateness of the method of estimating the scale and to suggest improvement directions. Therefore, in this study, we propose a method of estimating the size of the western flags by investigating and analyzing the main airports of overseas airports to determine whether the application of the Horon-jeff formula is appropriate.

  • Recently, the development of UAM, which was named by NASA as an alternative to solve the traffic and environmental problems caused by the rapidly progressing urbanization. When designing UAM, the location of lift fans greatly affects the core technology of the eVTOL type, distributed electric propulsion technology and aerodynamic performance of the vehicle. In this paper, a hybrid UAM model was designed using OpenVSP, an open source aircraft configuration modeling program, and aerodynamic analysis was performed according to the lift fans position change by the vortex lattice method. As a result, it is confirmed that the flight parameters and trailing wakes are stable by fixing the lift fan with the state rotated 0° to the flow direction of the aircraft during cruise flight. Also, OpenVSP is a suitable tool to be used in aircraft configuration modeling and design.

  • The development of the aviation industry and the changes in the military operation mission environment are demanding more long - distance operation (long - time flight), and such a flying environment is a risk factor for fatigue - related accidents. For the aviation related organizations such as ICAO and FAA, fatigue risk management system (FRMS) are applied along with flight time restriction regulations to prevent fatigue related accidents. The most important process in FRMS is fatigue risk management. Fatigue risk management systematically manages fatigue through scientific fatigue risk data collection and fatigue risk assessment. The purpose of this study is to applicate the assessment of scientific fatigue risk management to pilots of airplanes engaged in long flight. We reviewed the current state of risk management and FRMS through previous research. We also developed fatigue risk management indicators and examined the validity of internationally recognized fatigue risk data collection methods and fatigue risk assessment tools. There are 134 mission (flight) data used for development. In order to verify the indicators, the fatigue risk score between the items was assigned through pair-wise comparison. In addition, the verify test results were normalized.

  • Since the MPL (Multi-Crew Pilot License) Program was introduced in Korea in 2009, there has not been a single pilot licensed under the MPL Program. To successfully implement the MPL Program in Korea, it is necessary for an Approved Training Organization to develop the MPL Flight Instructor Training Program and foster excellent MPL Flight Instructors. However, there are no rules or guidelines regarding the MPL Flight Instructor Training Program in Korea. This study suggests the Training Specification for the MPL Flight Instructor, including the training syllabus, training and assessment methods. The MPL Flight Instructor Training Program should be composed of minimum 14-hour academic and practical training, which includes the concept of Competency-Based Training, CRM, Competency, Behavior Indicator and Assessment. To be qualified for the MPL Flight Instructor, candidates need to successfully complete the course and pass the practical test. In order to maintain the qualification, MPL Flight Instructors should comply to recency and recurrent training requirements.
