Since airline safety depends significantly on the role of pilot, the importance of airlines' training qualified pilots and investing in the training program grows. This study aims to analyze the determinants of the commercial airline pilot competencies during the transition course. To this purpose, one-year training evaluation results of 215 new airline pilots in the JET transition course of Company K in 2019 are studied with correlation coefficient analysis, factor analysis, ANOVA, and regression analysis. Undergraduate major and Uljin-trained pilots show higher final-stage scores in PROC, AUTO, and CRM. Due to Uljin-trained pilots' higher first-stage scores, their score increase during the course is limited. Uljin-trained pilots' MANUAL scores in the final stage are lower than those of undergraduate major and overseas-trained pilots. Influence of trained location is found greater than English competency, undergraduate GPA, and ground school scores on commercial airline pilot competency evaluation scores during the program. The results will be useful in establishing scenario-based training focusing on different background to apply competency-based training and assessment.

Due to the recent aircraft accidents both in Ethiopian airline and Malaysian airline, almost all the media are focusing the importance of the airline safety. Especially, media's eyes and ears are interested in the reasons why Malaysia airline's missing presumed as by either terrorist attack or pilot's mistake. Safety Behaviors of pilot are viewed as the most important human factor issues among researchers. This is because, if it were the case of a commercial airline, pilot's safety behavior would be directly related to the lives of couple of hundreds passengers. This paper considers the antecedents of this safety behaviors as pilot's leadership, pilot's leadership and self-efficacy. This paper has tried to find out which human factors of a pilot would have significant impact on their safety behaviors. According to the empirical research result from SEM (Structural Equation Model), it was found out both the leadership and self-efficacy of a pilot had direct impact on their safety behaviors through safety motivation. Thus it could be concluded that flight crew must follow the instruction of a pilot who had the authority of the flight operation. The managerial implication are discussed in the conclusion part of this paper. As an implication, this paper concluded that it would be necessary to do further research on pilot's leadership and self-efficacy.

Flight safety in modern commercial aircraft depends on the ability of pilots to manage overall flight operations. ICAO has made it mandatory for airlines to adhere to Crew Resource Management(CRM) policies to reduce operational safety threats. CRM is a set of techniques designed to effectively manage the human resources, aircraft, and environmental factors in order to promote safety and enhance efficient air operations. When looking at the career backgrounds of new pilots joining the Republic of Korea's commercial airlines, discharged military fighter pilots represent the largest demographic. Fighter pilots are experienced in empowering leadership and directive leadership from their military training and culture. New commercial airline pilots with military fighter pilot training should effectively acquire the required civil aviation CRM skills. The present study has been carried out to determine how the leadership experience of this demographic affects the acquisition of CRM skills for commercial airlines, and it confirms that there is a positive correlation.

It is necessary to establish a UAV pilot license and training system because the number of UAV-related accidents has rapidly risen. Most of accidents are caused by the human factors such as the lack of control skill and aviation knowledge. In this paper, we investigate licensing policy of small UAV pilots and examine the level of UAV licensing system and classification criteria based on comparative analysis of national cases such as USA, UK and China. Recently, the Ministry of Land, Infrastructure and Transport Affairs is planning to improve the safety regulation by taking into account the risk level of the licensing system, which has been classified according to the existing weight and commercial purpose. From the comparative analysis, we suggested a improvement policy for UAV licensing system in the view of pilot license segmentation, beyond Visual Line-of-sight flight and high risk UAV for non-commercial.

The purpose of this study was to analyze the face validity of the revised EPTA (English Proficiency Test for Aviation) to see if the tests actually contribute to the enhancement of aviation safety and achieve the purpose of the assessment. In order to reach the above objectives, 103 pilot test takers were surveyed, and nine in-depth interviewees were selected and interviewed. In addition, detailed research results were derived by dividing the participants into the pilot's flight experience (31 captain pilots, 42 first officer pilots, and 30 general commercial pilots). As a result, pilot participants were generally aware that EPTA was more reasonable because the revised EPTA properly implemented the aviation situation and gave participants motivation to learn aviation English. It was also seen that first officer pilots had a higher face validity of EPTA than captain and general commercial pilots. The reason was that first officer pilots considered air traffic control job was more important than other pilots did.

The purpose of this study is to efficiently treat the sewage sludge discharged from sewage treatment plants and evaluate the feasibility of the manufacture of lightweight aggregates(LWA) using a large quantity of sewage sludge. Sintered lightweight aggregate from sewage sludge is experimentally manufactured with various mass ratios of clay to sewage sludge by a pilot plant, and is tested for density, water absorption and crushing value. Their physical properties are compared to those of a commercial sintered lightweight aggregate. As a result, an experimentally manufactured lightweight aggregate is similar or superior in physical properties to the commercial lightweight aggregate. The manufactured lightweight aggregate could be used for structural concrete and non-structural concrete.

There is a concern in the aviation community that pilot schedules can lead to fatigue and increased chance of an aviation accident. Yet despite this concern, there is little empirical studies showing the relationship between pilot fatigue and commercial aviation accidents. At this point of view, countering fatigue is a challenging proposition in complex aviation operations. However, with appropriate planning, many strategies can contribute to pilot alertness and flight safety. With proper education program, sustaining a physiological fit, a right knowledge about pilot fatigue can design a safety operations. On this study, I inquire into the ways of enhancing pilot's efficiency from fatigue.

In this paper, two different flight training devices were constructed to verify the effectiveness of a pilot training system based on a Virtual Reality Head Mount Display. VFR Flight Procedure and IFR Flight Procedure were conducted by high level pilots with Commercial Pilot Licence. Flight data and pilot's visual data for each flight procedure were extracted, compared and analyzed with two training systems. Finally, the effectiveness of the training systems based on the VR HMD was demonstrated by assessing the given mission and the flight results.

This paper presents results of test for combustion vibration in the pilot furnace for fossil power plant under combustion test. We measured static pressure variation in the pilot furnace together with air and fuel flow. From test results, it shows that vibration magnitude is affected by air and fuel flow. Also, a finite element analysis using a commercial S/W is performed to calculate acoustic mode of the pilot furnace. These results show that dominant frequency occurred is related to acoustic natural frequency of furnace. After this, it needs to be studied the relation between dominant frequency of combustion vibration and air flow rate.

This paper describes the commercial application of custom ultrafiltration (UF) membranes in the resolution of two aqueous-based problems: the recovery and recycling of laundry wash water and the fmal polishing of sodium hydroxide sterilization solution in the dairy and brewing industries. Both applications are currently in the pilot Stage and employ custom-made UF membranes developed by Liumar Technologies Corporation of Ottawa, Canada.
