현재까지 항공기에 적용되는 기술들은 수많이 발전해왔다. 조종사의 편의성을 위한 기술들 또한 많이 발전해왔다. 자동운항 등 많은 기술들이 조종사를 보조하며 편의성을 위해 사용되고 있다. 하지만 비행기가 처음 만들어 졌을 때부터 바뀌지 않은 조종의 방식과 항공기의 국제성이 가지는 장시간의 비행은 여전히 조종사에게는 큰 피로를 안겨주고 있다. 본 논문은 조종사들의 피로를 경감 시켜 피로로 인해 발생 할 수 있는 사고들을 예방하기 위해 음성인식을 적용하여 새로운 조종의 방식인 '음성인식을 통한 항공기 조종면의 제어' 기술을 제안한다. 기존의 손을 사용한 조종방식이 아닌 컴퓨터와 조종사의 대화를 통해 데이터를 처리하고 즉각적인 피드백을 받으며 조종사의 편의성을 증가시켜 나아가 피로를 경감 시킬 수 있다.

항공기에는 많은 시스템이 있고 다양한 장치들이 있다. 이 장치들은 사용자의 명령을 입력받아 사용되는데 자동을 제외한 거의 모든 시스템들은 사용자의 직접적인 조작으로 작동된다. 하지만 여전히 완전 자동화는 되지 않아 사소하고 섬세한 부분에서 조종사는 수동으로 작동시켜 주어야하는 부분들이 있다. 사소한 부분들을 신경써야 하기에 조종사에게 피로는 필수적을 따라왔다. 본 연구에선 현재의 기술에서 더 나아가 음성인식(STT, TTS)을 활용하여 항공기의 다양한 장치들을 원격제어할 수 있게 개발하여 완전 자동화를 목적으로 한다. 음성을 이용한 방식은 조종사에게 손을 사용하지 않는 편리함을 제공한다. 조종사에게 원거리에서 음성으로 조작할 수 있게 해줌으로써 손을 사용하여 조작하지 않아 편의성을 제공할 수 있고 명령을 통해 컴퓨터가 처리함으로써 조종이 간단해진다. 본 연구로 인해 사소한 부분까지 신경쓸 필요가 없어져 조종사의 실수나 피로로인해 일어나는 사고를 방지할 수 있다.

Approximately 70% of aviation accidents in the world are caused by human factors of pilots and 15-20% of these accidents are known to be caused by pilot fatigue. Recently ICAO established new standards of FRMS for aircrew. The US and the EU have introduced FRMS and established and operated new aviation regulation systems for pilot flight(duty) time limitations. On the other hand, Korea has not yet introduced FRMS. This study reviewed ICAO's standards of FRMS and analyzed the aviation regulations of the US and the EU. As a result of this study, it showed that Korea also needed to introduce FRMS. This study reasoned out plans to improve Korean aviation regulations about pilot flight time limitations based on international standards.

Charles Lindbergh has experienced the uncontrolled situation of the aircraft while he was asleep with open eyes during his Atlantic crossing flight around 20 hours after departure from the New York in 1927 because of the fatigue. According to the NTSB(National Transportation Safety Board) reports, about 40 incidents are related fatigue in each year. The sleep loss is the most wanted item for the NTSB and may cause the similar effect as the alcohol does. The fatigue may affect the management of the threats and errors especially during take-off and landing. In this study, threats and errors of major accidents that NTSB analysed fatigue as a causal factor will be identified in order to understand the seriousness of fatigue.

Despite the development of the aviation industry, aircraft accidents due to pilots' human errors continue to occur. The cause of aircraft accidents due to human errors is that they cannot remove hazard factors that hinder flight safety in advance, leading to accidents. This study examined how job stress, fatigue, and anxiety, which psychologically and physically affect flight safety among various hazard factors, affect pilots' safety behavior for flight crew and pilots of general aviation working in domestic airlines. In addition, an empirical analysis was conducted to confirm the mediating effect of safety culture between job stress and safety behavior. According to the results of the study, job stress not only directly affects the safety behavior of pilots, but also affects the safety culture of airlines such as safety atmosphere and reporting culture. The purpose of this study is to improve the performance of the safety management system through the correlation between the pilot's job stress and safety culture and safety behavior.

During the COVID-19 pandemic, there have been many changes in the aviation industry as a whole. Passenger traffic has decreased, but on the contrary, the international transport demand for cargo planes has never been higher. Due to their geopolitical location when flying to major cities around the world, Korea's international pilots are bound to have relatively more jet lag-causing routes than their American or European-based pilots. Through this study, we tried to analyze the degree of fatigue and fatigue weighting factors according to operating conditions for domestic pilots. As a result of the study, the following conclusions were drawn. Despite the variety of models, routes, and fatigue between individuals, it was found that the 3 Pilot operation route was concentrated as a representative fatigue route. Most of the individual fatigue improvement request sections showed higher fatigue as the night flight section was longer among the 3Pilot routes for more than 12 hours, and 43 out of 90 participants (Korean Air pilots) focused on 3Pilot (two captains and one pilot) as fatigue-intensive operating conditions. Therefore, it proposes an improvement in the system of applying 12-hour unification standards according to Korea's geopolitical international operating conditions and time difference standards.

The highly maneuverable fighter aircraft such as F-22, F-16 and F-15have the high maneuverability to maximize the combat performance, whereas the high maneuver characteristics might degrade the pilot's mission efficiency due to fatigue's increase by exposing him to the high gravity and, in the worst case, the pilot could face GLOC (Gravity-induced Loss Of Consciousness). The advanced aerospace company has applied the various technologies to improve the pilot's tolerance to the gravity acceleration, in order to prevent the pilot from entering the situation of the loss of consciousness. Especially, the Anti-G Suit(AGS) equipment to protect the pilot against the high gravity in flight could improve the mission success rate by decreasing the pilot's fatigue in the combat maneuver as well as prevent the pilot from facing GLOC. In this paper, a control algorithm is developed and verified to provide an optimal air pressure to AGS according to the gravity increase during the high performance maneuver. This result is expected, as the key technology, to contribute to the KF-X(Korean Fighter eXperimental), project in the near future.

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.
