The T-50/A-50 Golden Eagle was developed for a supersonic trainer and light combat aircraft. At the design stage, vibration control plans were established and applied. For cockpit vibration, crew comfort vibration level was defined by the requirement of MIL-A-8892. It is found that the T-50/A-50 meets the requirement of cockpit vibration from the flight test data analysis. This paper contains the results of cockpit vibration analysis using the flight test data and the results of human vibration analysis lot the pilot inside aircraft. The human vibration level of pilot is increased as dynamic pressure is increased and at the specific high dynamic pressure, the ride comfort indicates 'a little uncomfortable'. Overall analysis results show that the vibration level of T-50/A-50 cockpit is tolerable and not critical for pilot's comfort.

In this paper, it has implemented the design for the K-Line Operations Safety Audit(K-LOSA) designed to provide a proactive snapshot of system safety and flight crew performance before an incident and accident. It introduces the a LOSA and ten operating characteristics that have come to define LOSA methodology. According to the LOSA methodology, we explain the conceptual and detail design and implement the prototype for the data collected with LOSA collection tool.

Coronavirus disease 2019 (COVID-19) reduces airline passengers, which leads to a sharp decline in airline sales. They are concerned about the dismissal or unpaid leave of the flight pilot and crew, and the management of the passengers is also under great stress. Stress management methods for COVID-19 can be divided into general stress management such as 'Let's change me', 'Let's find the source of life', and 'Let's ask for help', and mental health management in a disaster situation.

The Nose Landing Gear(NLG) of Rotary Wing Aircraft is an essential equipment in Landing System for pilot to perform a flight mission. It supports the fuselage at ground and absorbs the impact from the ground when landing, thereby, these functions sustain operational capability for pilot and crew. However, the A aircraft caused stick-slip behavior when it was stationed on the ground. Therefore, this paper summarizes pilot comment in operation which are classified by cause of occurrence and the troubleshooting process about each comment. It also describes design improvements which was derived from troubleshooting and suggests verification results of flight test.

The purpose of this study is to analyze the relationship between the safety, working condition and the organizational commitment among crews members of airline companies in Korea. The data were collected from 230 employees of the a private airline company who gave their informed consent and completed a self-reported questionnaire in November, 2014. A structural equation model was established. The fitness of the hypothetical model was adequate (${\chi}^2=88.424$, df=48, RMR=0.044, GFI=0.940, CFI=0.964, NFI=0.926, IFI=0.965). Analysis of the hypothetical model demonstrated that effects of safety, working condition were significantly correlated with organizational justice and organizational commitment. The results of this study indicate that it is necessary to develop a safety program and working condition to encourage better organizational commitment of the pilot, leading to a brighter future for domestic airline business.

항공 사고는 첨단 항공 기술의 발달로 꾸준히 감소해 왔지만, 여전히 발생하고 있다. 조종사는 목적지 공항까지 안전하고 효율적으로 비행하기 위해 위협과 오류를 관리해야 한다. 조종사에게 영향을 미치는 위협은 환경적 위협과 항공사 위협으로 나눌 수 있으며, 환경사위협에는 객실 위협이 포함된다. 조종사와 객실 승무원은 정상적인 운항 중에는 협력이 필요하며, 비상시에는 안전한 비행을 위해 효과적인 협력이 절대적으로 필요하다. 조종사가 비행 중에 간섭이나 작업 흐름의 중단이 발생할 때 에러를 할 가능성이 높아진다. 항공사들은 안전 운항을 방해할 수 있는 객실위협의 종류를 적극적으로 식별하고 분석하여, 조종사들이 안전한 비행을 유지하기 위해서 위협을 관리하도록 절차 및 훈련을 개선해야 한다. 본 연구는 안전관리시스템(SMS)의 안전도구인 LOSA(Line Operation Safety Audit)를 기반으로 기내위협의 유형을 파악하고, 항공사들에게 조종실위협 관리를 체계적으로 개선하는 데 필요한 객실위협과 간섭에 대한 자료를 제공하고자 한다.

Pilots have used checklist as a valuable tool to improve aviation safety and to reduce human error. A checklist however is too complex for a student pilot to use with less flight experience or time than a commercial pilot. It is agreed upon such complex checklist be a factor to threaten aviation safety for student pilots. This paper has focused on a checklist by dividing it into a couple of basic three flight procedures. Making exploratory case study of student pilots, researchers could analyze the correlation between checklist factors and those of human errors. First of all, it was necessary for student pilots to be educated professional knowledge regarding aircraft structures and engines to perform preflight inspection reducing human errors. Moreover it was recommended student pilots as well as maintenance crew confirm checklist together to enhance aviation safety.

The International Civil Aviation Organization (ICAO) introduced a safety management system in the aviation sector for aviation safety and mandated the implementation of safety management systems and national safety programs. The activation of the airline's safety management system is not just a requirement for organizational members to create and comply with necessary regulations, but a safety culture to promote and improve flight safety must be established within the organization. Therefore, the safety culture of airlines acts as a major key variable in the safety management system that directly affects safety performance. This study compared the data from the European pilot safety culture awareness, which was the basic data of the survey, with statistics on the safety culture awareness of domestic flight attendants to analyze the differences in safety culture between the two groups.

Flapper Valve of Korean Utility Helicopter(KUH-1) is an essential equipment in Environmental Control System(ECS) for pilot to perform flight mission. It provides pilots and crews with heating, ventilating and air conditioning. It has function of maintaining room temperature to sustain operational capability for pilot and crew. This paper summarizes pilot comments in flight test which are classified by cause of occurrence and the troubleshooting process about each comment. It also describes design improvements which was derived from troubleshooting and suggests verification results of flight test at low temperature.

In this study, emotional intelligence which is defined as knowing yourself and other people's emotions and the ability to use regulation was judged as an important factor for the service quality implementation of aircraft crew members perform to work in special circumstances. And the purpose of this study is how emotional Intelligence affects job satisfaction and organizational loyalty. So we analyze the emotional intelligence of the K domestic airline crew in this study. This study showed that emotional intelligence affect high quality of service to perform the work well and contribute to job satisfaction. And job satisfaction has a positive impact on organizational loyalty also. Therefore, the ability of airlines to improve service quality as well as performing work also for the emotional intelligence to increase satisfaction and loyalty unplug staffs and it will require ongoing sensitivity training.
