The pilot aptitude test so far has been conducted with a dichotomous concept of cognitive factor and non-cognitive factor, so it was not easy to explain concrete factors about pilot aptitude. Therefore, an integrated approach is needed to construct pilot aptitude test including all factors that can predict pilot aptitude. In previous study, we developed questionnaire items for the Pilot Aptitude Personality Test(PAPT) which can predict the flight training achievement through personality and personal characteristics. And those items were categorized as personality, cognition, and motivation factors. The flight training grades were correlated with all the test factors of the items, and the cognitive factors were high. As a result of the regression analysis, the total score of the three factors together accounted for 16% of the flight training grades. The results of the ANOVA showed that the cognition factors and motivation factors had significant effects on the completion of the flight training. The factors of PAPT predicted not only the completion of the flight training but also the flight performance. This is because the existing paper-pencil pilot aptitude test can only discriminate the flight training completion status. This is also a result of the fact that the introductory flight training consists of various factors including not only basic cognition but also personality and motivation.

The purpose of this paper is to investigate the current technical status and future prospects regarding helicopter simulators. In the introduction section, we briefly summarize the concept of the simulator and the development history of helicopter simulators. In the main section, the development status of helicopter simulation technology is first presented and the FAA/EASA certification is then introduced as a verification method for the reliability evaluation of the developed simulator technology. In addition, several issues that need to be resolved along with future development directions are discussed to improve the reliability of helicopter flight simulator.

The primary objective of this paper is to introduce the application of Human-Machine Interface (HMI) and Augmented Reality (AR) technologies in flight operations. These include: self-check-in, baggage handling, airport security and surveillance, airport operations monitoring, In-Flight Entertainment and Connectivity (IFEC), cockpit design, and cabin crew support. This paper investigates the application status and development trends of HMI and AR technologies for airports and aircraft. These technologies can provide more efficient in-flight passenger service and experience by using AR devices. This paper also discusses the developments such as; the Integrated Control Application (ICA) for the IFEC interface, AR flight simulation training program using the fixed-based simulator, and the AR aircraft cabin interior concept test program. These applications present how HMI and AR techniques can be utilized in actual flight operations. The developed programs in this paper can be applied to their purpose within aircraft interiors and services to enhance efficiency, comfort, and experience.

In this study, we surveyed the operating status of the Light Sport Aircraft(LSA) in Korea, and reconstructed the flight route for Light Sport Aircraft in Yecheon TMA. Amended flight routes are LS095(Danyang Airpark $\Leftrightarrow$ Yeongju Airpark), LS096(Andong Airpark $\Leftrightarrow$ Yeongju Airpark), LS098(Yeongdeok Airpark $\Leftrightarrow$ Yeongju Airpark) and LS099(Yeongdeok Airpark $\Leftrightarrow$ Andong Airpark).

In this paper, a operation network system equipped with onboard wireless communication systems and ground-based mission control systems is proposed for swarm flight of small UAVs. This operating system can be divided into two networks, UAV communication network and ground control system. The UAV communication network is intend to exchange the informations of navigation, mission and flight status with minimum time delay. The ground control system consisted of mission control systems and UDP network. Proposed operation network system can make a swarm flight of various UAVs, execute complex missions decentralizing mission to several UAVs and cooperte several missions. Finally, PILS environments are developed based on the total operating system.

The purpose of this study is to provide in-flight security in situations where aviation security is constantly threatened by the increase in illegal interference in aircraft and the threat of terrorism that still exists. It is to identify legal operational problems such as education and qualification of the original system and to propose improvement measures. To this end, the need for revision based on relevant laws and guidelines such as "Operation Guidelines for In-Flight Security Officers" is to be discussed based on international standards such as ICAO and Federal Air Marshal. The research method was based on interviews with SEMs such as cabin managers, which focused on ensuring the legal status of In-Flight Security Officer, establishing relationships with captains, and improving education and training.

In order to evaluate the physical and mental health status of airline flight attendants, 136 airline flight attendants were given a general health questionnaire (Todai Health Index), and the prevalence of their subjective complaints was measured. Collected data were classified according to age distribution, length of employment, service area, smoking status, job satisfaction, gender, and marital status. The results obtained were summarized as follows: 1 The scores of health complaints of physical items were higher in the oldest group $(age 50\~60)$ than in younger groups. The THI eye and skin symptom scores were significantly higher for the oldest groups than for the younger groups. 2. The health complaints scores of physical items were higher in the long-length employment group (more than 5 years), whereas most scores of mental items were higher in the short- length employment group (less than 2 years). The THI mouth and anus scores for the long-length employment group were significantly higher than for groups of workers who had been employed for a shorter time. 3. THI scores were higher for domestic airline crews, dissatisfied workers and females. 4. The irregular life THI score was significantly higher among domestic crews than international crews. 5. The impulsiveness and depression scores were significantly higher in the dissatisfaction group. 6. The female group showed higher scores in the multiple subjective symptoms, mental irritability, depression, and irregular life categories. 7, The THI scores of the mouth, anus and nervousness were significantly higher for the married group than for the unmarried group. In summary, this study shows that the health complaints scores of physical and mental symptoms tended to be higher among the aged group, domestic airline crews, the dissatisfaction group, and females. These results can be used for improving the psychosomatic health status and working environments of flight attendants.

This study aims to determine how agricultural drones are operated for flight tests using a 5G communication in order to carry out a mission such as sensing agricultural crop healthy status with special cameras. Drones were installed with a multi-spectral and IR camera to capture images of crop status in separate altitudes with different speeds. A multi-spectral camera can capture crop image data using five different particular wavelengths with a built-in GPS so that captured images with synchronized time could provide better accuracy of position and altitude during the flight time. Captured thermal videos are then sent to a ground server to be analyzed via 5G communication. Thus, combining two cameras can result in better visualization of vegetation areas. The flight test verified how agricultural drones equipped with special cameras could collect image data in vegetation areas.

As demand for drone test flight is rapidly increasing, it is difficult for Goheung Aviation Center alone to meet the test flight demand. Newly developed drones or modified existing aircraft carry potential flight risks due to unpredictable flight performance or poor pilot skill when performing test flights outside the test site. Therefore, it is necessary to ensure sufficient test flight space for the safety verification of manned and unmanned aircraft. Therefore, this study analyzed the status of domestic flight test site and chapter 5 of ICAO DOC 9184-AN / 902 Part 1 (Airport Planning Manual). And to build a comprehensive flight test infrastructure, the methodology for preliminary evaluation of candidate sites for flight test sites and a method for evaluating infrastructure test sites was presented.
